return():
first string
s2 second string
returns
-1 if s1 < s2
0 if s1 = s2
1 if s1 > s2
This allows you to compare strings with case sensitivity in place. If
you don't care about the case of the string use the normal '==' '>',
'<', '<=', '>=', symbols.
example:
first string
s2 second string
l amount of significant digits to compare
returns
-1 if s1 < s2
0 if s1 = s2
1 if s1 > s2
This allows you to compare strings with case sensitivity in place and it
allows you to choose how much of the strings are compared.
example:
the PC unit doing the editing
return When done editing it returns SFB_EDIT and activator
is set to PC
The 'BEGINEDIT' function sets a PC into editing mode. while in edit mode
the PC field 'editing is set to true. Once the PC is done editing a 'SFB_EDIT'
message is sent to the unit editing to continue on with the DIL.
If for some reason the PC needs to break
out of the editor before it is done editing then the Dil needs to call
the 'killedit' function
<A HREF="#sect-beginedit">interrupt editing before done</A>
example:
the target string you want to replace
n what you want to replace the target with
o the original string
return the string with the old string replaced by the new string
This function replaces all occurences of a string in another string with a
new string.
Example:
The name of the Unit file
u The Unit you want to restore into or null if none
Return if 'u' null returns a pointer to the Unit loaded,
if 'u' not null returns null and loads Units from the specified file into the
unit 'u'
restore loads a copy of a unit or units which were previously saved with the
'store' command. Just as with "load", the unit is put inside the unit which
executes the restore command unless the 'u' argument is not null. If the 'u'
argument is an unitptr like room, object, npc, or pc the items restored will be
placed inside the 'u' Unit..
Note, It is only possible to restore items as long as the main-database
contains a reference for the unit 'name@zone'. Use 'Store' and 'Restore'
sparingly, remember that items saved in player's inventories are automatically
saved in this instance.
The 'store' and 'restore' are perfect for operations such as mud mailing
objects from player to player, storage devices for players that will keep
inventory through a reboot. Even the ability to save a players inventory while
they fight in an arena and restore it to them undamaged when finished. Finally
it could be used to save a donation room through reboots since it can be used on
a room to store the contents of a room any NPC or objects in the room would be
saved through reboot.
Disk access is always slow.
If you use 'Restore' on a continuous basis always attempt to keep file sizes to
a minimum for quick loading. Otherwise you might cause serious delays on the
server. If the Dil that uses Restore saves at certain times try to make it so
the saves are spread out over as large amounts of time as possible.
Example 1:
the character that should make an additional attack
v the character being attacked
b any penalty or bonus added to the attack.
wt the weapon type of the attack, if a valid type then that
is used for the attack purpose, otherwise the default
weapon/hand attack is used.
returns The amount of damage done or -1 for failed
ch' performs an attack (using whatever weapon is wielded or his bare hands) against 'vict'.
If wtype is within a valid weapon range (WPN_XXX) any weapon will be bypassed,
and the value will be used as the attacktype. Good for things like "meleeattack
(ch, vict, bonus, WPN_CIRCLE_KICK)" If you want person to be able to perform an
extra attack even though wielding a weapon or something. Note that this will
require BOTH a weapon type WPN_CIRCLE_KICK and a skill "kick" in order for it to
work.
Example:
the original string to be parsed
s The starting point of the string to be parsed out
e the ending point of the string to be parsed out
return the portion of the string defined by the 's' and 'e' values
This function parses the string passed to it and returns the portion of the string
defined by the start value and the end value that is also passed to the function.
Example:
String to lower case
return the string passed in lower cased
This function returns a copy of the string passed in but with out capitals.
Example:
String to lower case
return the string passed in lower cased
This function returns a copy of the string passed in with all characters changed
to be capitalized.
Example:
the unit that you want to check the password of
s the password you are using to check
Return Returns an integer TRUE if pcname is the units password
FALSE if not
This function checks the string against the units password and returns TRUE
if they match.
Example:
The name of the String file to be deleted
Return Returns an integer TRUE if deleted FALSE if not
The delstr is used to delete files that are used with the 'loadstr' and
'savestr' functions. The delstr function will only delete files that
each individual Zone has access to which is set up in the Zonelist file in the
VME etc directory.
Example:
The name of the Unit file to be deleted.
Return Returns an integer TRUE if deleted FALSE if not delunit
is used to delete files that are used with the 'Restore' and 'store' functions.
Example:
Unit that you are checking
returns TRUE' if item is a light, 'FALSE' if it is notway to small', 'to small', 'way to large', 'to large', or null if fits
Simply checks the item to see if it is a light.
the name of the player being checked
Return Returns an integer TRUE if pcname is a player FALSE if not
This function is used to find out if a string you pass to it is a player or not.
This can be used and is used to find out if a player is truly a player that an
Administrator is deleting with out having that player on line.
Example:
The file name you want to check
return a file size in bites 0 if no file
This function does exactly what it says it does it checks a files size.
Example DIL:
The Filename of the file to appear in the log directory.
s The string to be logged.
wa Write or Append
The 'flog' function allows you to split up your logs in the log directory
so that you don't end up with everything in the main vme.log.
Note:
The append/write argument must be in lower case and can only be a 'w' or a 'a'
surrounded by '"'. If the argument is a 'w' it will over write any log file
by that name. If the argument is 'a' it will append to the file by that name.
Example:
the original string to be parsed
l The amount of characters to parse out
return the left portion of the string with length l
This function parses the string passed to it and returns the number
of characters defined in its second argument.
Example:
The name of the string file to be loaded
buff The string that you wish to read the file contents into
Return
the original string to be parsed
r The amount of characters to parse out
return the right portion of the string with length r
This function parses the string passed to it and returns the number of characters
from the right defined in its second argument.
Example:
The Filename of the file to appear in the log directory.
s The string to be logged.
wa Write or Append
The 'flog' function allows you to split up your logs in the log directory
so that you don't end up with everything in the main vme.log.
Note:The append/write argument must be in lower case and can only be a
'w' or a 'a' surrounded by '"'. If the argument is a 'w' it will over write
any log file by that name. If the argument is 'a' it will append to the
file by that name.
Example:
The wild card file you want to match or '*' for all.
return a Stringlist with all the filenames that match the
'match' argument.
The 'match' argument uses the same wild cards as the Linux 'ls' command
so the following will work.
* Match any character or group of characters
? Match one of any character
[...] Match one of a set of characters
Example:
the unit that you want to set the password of
s the password you are using to set
This function sets a unit password it only works on Players characters of corse.
Example:
The Unit that has the contents to be stored or is to be stored
filename The name of the file you want to store the Units to
container Do you want to save the container 'TRUE' for yes, 'False' for no
Store saves a copy of a unit or units. If the container value is 'TRUE'
everything inside including the container itself will be saved. If the container
argument is 'FALSE' only the contents of the object will be saved. You will want
to use the 'TRUE' value when saving something like a Clan chest that has items
inside to store and has extras on the chest that you also wish to keep. The
'FALSE' value for container would be good for temporary storage of PC inventory
or for storing room contents.
The 'store' and 'restore' are perfect for operations such as
mud mailing objects from player to player, storage devices for players that will
keep inventory through a reboot. Even the ability to save a players inventory
while they fight in an arena and restore it to them undamaged when finished.
Finally it could be used to save a donation room through reboots since it can be
used on a room to store the contents of a room any NPC or objects in the room
would be saved through reboot.
Disk access is always slow.
If you use store on a continues basis, it is essential that you do so ONLY if it
is needed and even then, only at amply spaced intervals. Otherwise you might
cause serious delays on the server. Remember that items saved in player's
inventories are automatically saved in their instance.
Example 1:
the command string that is sending the message
a the unitptr (activator) that activated the message
m the unitptr (medium) that the Dil is acting through
t the unitptr (target) the Dil is acting on
p the power of the message
arg the argument sent with the message
o the unitptr (other) you also want the message to go to
This sends the 'SFB_DONE' message to any dils that are waiting for it in the
surrounding area and to the other pointer if not null. The following is just
one example you can find many more in commands.zon
Example:
the command string that is sending the message
a the unitptr (activator) that activated the message
m the unitptr (medium) that the Dil is acting through
t the unitptr (target) the Dil is acting on
p the power of the message
arg the argument sent with the message
o the unitptr (other) you also want the message to go to
New Function send_pre(...) takes same arguments as send_done but returns either
SFR_SHARE or SFR_BLOCK.
If the command is blocked by another special or dil, then SFB_BLOCK will be returned,
and you should quit your dil.
Example:
character you are adding the color to
ks key string for the color
cstr color string
This function allows your Dils to create and add their own personal colors to a players
color list. That way you can actually make an act in a color that the player chooses or
you yourself choose.
Function:
character you are deleting the color from
ks key string for the color
This function is used to delete any colors from a players personal color list.
Function:
character you are deleting the color from
ks key string for the color
returns returns the color in a string
This function returns what color a player has for a key in the players list.
Function: character you are changing the color on
ks key string for the color
cstr color string
This will change a color in a players personal list.
Function:
unitptr - person you are stoping the fighting for
vict unitptr - person you are removing from the fighting or null for everyone
This function can be used to cancel combat in a room or with two people.
The following example copied to a player will stop any fight the player is in.
Example:
:Unit to remove from game
The destroy function works in two ways depending on the Unit being acted on.
If the Unit being acted on is a PC the player is saved and ejected from the game.
If the Unit being acted on is a NPC, or an Object. the purge function destroys
the Unit. Currently destroy will not destroy rooms.
This is different from the old destroy function in that it removes the player
out of the game instead of leaving the player in the menu.
Example
Weapon to get the name of ass defined in 'values.h' and 'weapons.def'
returns The name of the weapon that corresponds with the integer value
example:
Weapon to get the info of ass defined in 'values.h' and 'weapons.def'
returns Intlist containing 4 values:
0 Number of hands
1 weapon speed
2 weapon type
3 shield block value
This function gives you access to the values in the weapons.def file.
With this things like 'wear' equipment' and 'look' are much easier to
write in Dil.
Example
Skill to get the name of ass defined in 'values.h' and 'commands.def'
returns The name of the skill that corresponds with the integer value
example:
- is a string that will be shown to other mobiles when the act is executed.
To refer to the following arguments use the <A href="#formatters">formatters</a> listed below.
visibility
- is an integer that defines what happens if the mobile that is about to receive the
message can't see the activator.
If the receiver cannot see char, replace any reference to char with
someone.
If the receiver cannot see char, don't send the message at all. Use
this when missing vision should eliminate the perception of the action
the message represent. One instance where it is used is in smile. You
would need a ridiculously sensitive ear to hear, let alone percept
that someone's smiling if you can't see them. Do not use it if
'sound' is inherent in the message.
Works exactly like - is a unitptr, and the most important argument in the act. If this
is not valid the act will never show, leaving mobiles without
the message.
medium
- is a unit pointer, an integer or a string. Use this at your
leasure.
victim
- is a unit pointer, an integer or a string. Certain flags in
the next argument rely on the validity of victim.
- is an integer that defines who gets the message.
Sends the message to the entire room, excluding 'char'.
Sends to 'victim' only. 'victim' must be valid, naturally.
Sends the message to the entire room, excluding 'char'
and 'victim'. Perfect for bystanders in a melee.
Sends the message to 'char' and no one else.
Sends the message to everybody in the room.
This is a bit different from the rest. In sends the
message to all other units in the local environment,
excluding those inside 'char'.
will be sent to the receiver as a single `$'
'$', followed by a number and an extra character.
means this formatter refers to the 'char' argument.
'2'
means this formatter refers to the 'medium' argument.
'3'
means this formatter refers to the 'victim' argument.
the formatter will be replaced with the name of the unit, or
(depending on the visibility)
'something' or 'someone'.
'a'
'a' or 'an' depending on the name of the unit referred by the number.
'e'
'it', 'he' or 'she' depending on the gender of the unit referred
by the number.
'm'
'it', 'him' or 'her' depending on the gender of the unit referred by
the number.
'n'
the formatter will be replaced with the title of the unit, or
(depending on the visibility) 'something' or 'someone'.
'p'
'fighting', 'standing', 'sleeping', etc., depending on the position
of the unit referred by the number.
's'
'its', 'his' or 'her' depending on the gender of the unit referred
by the number.
't'
the string in the argument referred by the number.
Example:
act("You step over $2n.", A_SOMEONE, self, litter, null, TO_CHAR);
act("$1n steps over $2n.", A_SOMEONE, self, litter, null, TO_REST);

The name of the String file to save the String to
buff The String you wish to save into the file
wa Write or append
Return the stringlist you are removing from
i the index you want to remove
This function allows you to remove a string from a stringlist with out
leaving a blank spot in the stringlist.
Example:
player your resetting
This function simply resets a players level. Can be used in functions
like reroll where you set the players back to the way he first logged on.
Example:
player your resetting
This function simply resets a players virtual level. Can be used in functions
like reroll where you set the players back to the way he first logged on.
Example:
player your resetting
Reset a characters race, weight, height, age, lifespan, and costs for training.
As if you first log on the character. Great for reroll along with 'reset_level' and 'reset_vlevel'.
Example:
The wild card file you want to match or '*' for all.
return a Stringlist with all the filenames that match the 'match' argument.
The 'match' argument uses the same wild cards as the Linux 'ls' command
so the following will work.
* Match any character or group of characters
? Match one of any character
[...] Match one of a set of characters
Example:
the player name you want to delete
This function deletes a player but it doesn't check to see if it
was deleted or if it even existed you will have to do that with 'isplayer'.
Example:
the stringlist or intlist you are inserting to
i the index where you want to insert the string
s the string you want to insert
This function allows you to insert a string in a stringlist or intlist
with out re-writing the entire stringlist or intlist to do it. The
following Dil will add a string in order to a stringlist.

This documentation is designed for people with some experience in programming. Experience in C is recommended, but PASCAL or BASIC in some form or other will do just fine too.
DIL is a simple programming language with fixed types reflecting the types used in Valhalla Mud. The language gives you almost endless possibilities in designing your adventures and quests. It gives you the control you need for making the game interesting and intelligent.
<IMG SRC="../images/backgr/waveline.gif" BORDER="0" HEIGHT="18" WIDTH="100%">
Making a program:
You define your DIL programs within your zone file. Each program you make is a *template*. Such a template must be equipped with a unique name (for that zone). Templates can either be defined in a new %dil section, just below the %zone
section in the zone file, or directly attached to units defined in your zonefile.
If you define your DIL templates inside a unit definition, that unit is automatically assigned a program using that template. If you want to use an already designed template, either in your own, or another zone, you use a special function named "dilcopy", that takes the name of a template, and any optional parameters in parenthesis. The parameters of a template called with 'dilcopy' may only be of types integer, strings and stringlists.
Example:
dilcopy myfunc@myzone("say Hello, my friend!", 1, CMD_SAY, {"name1", "name2"});
DIL templates can always be reused. In fact, with version 2.0 of DIL, programs are no longer saved with equipment, but only a symbolic reference is used. That way, if you make a change in your zone, ALL units using that program are changed. This however requires you keep the name. Upon loading, if a template is not found, the program is halted and rendered useless until such a reference can be found during loading.
Technical note:
When you use several 'dilcopy' in your zonefile, only one instance is present game-time, thus saving tremendous amounts of memory. It is similar to a shared library, in which code is shared but variables are not.
You may use your templates to define both procedure and functions for your other templates to call.
A template is defined by beginning with 'dilbegin' and ending with 'dilend'. Inside the template your program section is defined, marked by the keyword 'code', followed by the program itself;
dilbegin myprogram(); var i : integer; j : integer;
code
{
heartbeat:=PULSE_SEC*5;
:start:
exec("say Hello world", self);
pause;
goto start;
}
dilend
This simple template does nothing but making its owner say 'Hello world' once every 5 seconds. The template is called 'myprogram' and takes no arguments. The 'pause' command waits for the program to receive a timer message, whose interval is set by the 'inline' variable 'heartbeat'. The 'self' variable is a unitptr referring to the unit owning the DIL program. Other inline variables will be explained later.
For a DIL program to work, it must be part of a *unit*: a room, player, non-player or object. The program uses *messages* to operate. Your program gets activated when it receives a message that some command is being executed, or a certain amount of time has passed. You decide yourself in the program, what to wait for, before the program continues executing.
Supposing you want your program to contain variables, you have to put them in a section before the 'code' section marked 'var'. The variables are declared by their type and their name, separated by a ':' and ended by a ';'
For an example, see the program above. Variables of type 'string', 'stringlist' and 'integer' are saved, if the unit the program is attached to is saved with player inventory. Variables of type 'unitpr' and 'extraptr' are 'volatile'. This means that they are cleared whenever there is a chance that their contents may have been rendered non usable. This ensures that you do not have any 'loose' pointers. However it is possible to 'secure' the contents of a 'unitptr' type variable of a unit located in your local environment (the units directly 'visible' to the unit who owns the DIL program) (see the secure / unsecure functions).
<IMG SRC="../images/backgr/waveline.gif" BORDER="0" HEIGHT="18" WIDTH="100%">
Data Types:
DIL supports a fixed set of types you can use and manipulate. Through these, you can get and manipulate information about almost anything in the game. The types are listed below:
String:
A string is some text. They are used for a lot of things such as command arguments, room descriptions etc. String variables are automatically resized and allocated when you assign them, so you do not have to worry about the string length nor allocation in your DIL programs. Strings may be compared either with '==' (equal to), '!=' (not equal), '<=' (less than or equal to), '>=' (greater than or equal to) '<' (less than), '>' (greater than.
Static strings are defined just as in the rest of the zone, within double quotations. Strings may be searched easily with the 'in' operator. Variables of type string are saved with DIL programs, if attached to a saved unit.
Example:
"This is a static string"
Strings may also be added to each other, in an expression.
Example:
"say "+itoa(42)+" is the answer!"
Example:
if (self.name == self.names.[1]) ...
Elements of the string can also be accessed by referencing them by their position.
Example
if (str.[3]==f])
{
exec ("say The 4th element is a F.",self);
}
Note
Currently you can only access the single elements of a string you can not set
them. In the future this will be possible. You can still accomplish this by
copying one string to the other one element at a time and changing any that you
want something like this.
Example
i:=0;
ln:=length (str);
while (str.[i]<ln)
{
if (str.[i]=="f")
newstr.[i]:="b";
else
newstr:=str.[i];
i:=i+1;
}
str:=newstr;
This snip of Dil would replace any 'f' in a string with a 'b' remember dil is
not case sensitive so it will also replace an 'F'.
Stringlist:
A stringlist is a list of separate strings. This is used for things such as (multiple) names or keywords. You may request a specified word in a stringlist by its number. Example:
mystring := self.names.[2];
Returning null if out of bounds of the stringlist (see 'length()'). Static stringlists are defined just as in the rest of the zonefile, as a comma separated list of static strings within curly brackets.
Example:
mysrtringlist := {"Some string","another string","the last string"}
Stringlists are modified through the 'addstring()' and 'substring()' procedures. Stringlists are searched easily by the 'in' operator. See documentation below. They can also be set directly (see example above). Variables of type string are saved with DIL programs, if attached to a saved unit.
Elements of each separate string in a stringlist can be accessed by appending a separate position at the end of the request for a string as follows:
Example
if (strlist.[5].[3]=="b"){
do something
}
Note See the strings for more information on accessing a single element.
Integer:
Non-fraction numbers can be used throughout your DIL programs. They are given normally, or in normal C style hexadecimal, preceded with '0x'. Integers are signed 32-bit integers. Variables of type string are saved with DIL programs, if attached to a saved unit.
Example:
0x10
Example:
2
Integers are used within expressions as both number value and boolean(true/false) values. You may use comparison between integers through the comparison operators: '==' (equality), '<' (less than), '>' (greater than), '<=' (less or equal), '>=' (greater or equal) '!=' (not equal).
Example:
if (42<12) ...
Returning the boolean value (true/false) depending on the comparison between integers. The result may be stored in an integer variable, and tested later, or used directly in an 'if' or 'while', etc. You may also operate on boolean expression themselves, using LOGICAL operators 'and','not','or', which allows you to combine the expressions.
Example:
if ( not ( (self.hp<42) or (self.level>10) ) ) ..
Integer expressions may also use a number of other operators: '+' (addition) '-' (subtraction/negation), '*' (multiplication), '/' (division), '|' (bitwise or, for flags), '&' (bitwise and, for flags)
Precedence rules for using these operators are still somewhat messed up. You'd better use parenthesis where ever possible.
Intlist:
Intlists are an array of integer types. They can be set directly as follows:
Example
wpn:={5,3,6,9,3,9};
The intlists can be accessed in the same way stringlist are accessed as follows.
Example
if (wpn.[5]==5)
{
do something
}
The intlists are saved on savable units.
</A> 5.3 The Integer List</A>
Type:intlistThis variable type allows you to keep an ordered list of integers with out having to create a variable for each integer. Example:Setting an intlist
myintlist:={1,5,9,2,8,5}; myintlist.[10]:=50;
If you set a index that is higher then the highest index, every index in
between will be set to zero. For example if you only have two values in the
intlist and you set index value 10 to 50 all indexes between 2 and 10 will be
set to 0.
Example: Using intlists
if (myintlist.[5]==5){ stuff }
if (myintlist<myint){ stuff }
i:=0; ln:=length(myintlist); while (i<ln){ myintlist.[i]:=i; i:=i+1; }
See Also:
Extraptr:
Extra descriptions, quests structures, etc can be searched and manipulated using variables of this type. There is no way to declare static structures of this type in DIL programs. Lists of extra descriptions are easily searched with the 'in' operator (See below). Extraptr variables are 'volatile', and thus cleared whenever there is a possibility that they are rendered unusable.
Type: cmdptr
cmdptr fields
name
string - command name
type
integer - command type like social or skill or just command
level
integer - minimum level to use command
loglevel
integer - level of character that can see the log 0 for no logs
position
integer - minimum position to use command
next
cmdptr - pointer to the next cmdptr
previous
cmdptr - pointer to the previous cmdptr
The cmdptr can be used to search the command list or display all the commands.
I0t is also now possible to sort the commands by type by defining your own command
types and using the type field to sort on.
In order to get the first command in the list you use the following function:
Function: chead();
If you want to get a specific command then you use the following function:
Function: cmdptr := getcommand (s : string );
Example:
dilbegin cmdtst(arg : string); var cmd : cmdptr; st : string;code { cmd := chead();
while (cmd) { st := cmd.name + " " + itoa(cmd.level) + " " + itoa(cmd.type) + " " + itoa(cmd.loglevel) + " " + itoa(cmd.position); act("CMD: $2t", A_ALWAYS, self, st, null, TO_CHAR); cmd := cmd.next; }
cmd:=getcommand("kick"); sendtext ("You must be "+itoa(cmd.level+" to use kick&n",self);
quit; } dilend
Unitptr: Unit pointers are used to keep track of units: rooms, players, non-player or objects. Through a variable of this type you can access most of the information in a unit. Unitptr variables are 'volatile', and thus cleared whenever there is a possibility that they are rendered unusable.
Type: zoneptr
Zone Pointer Fields
next
The 'zoneptr' works like a unitptr. To get the first zoneptr in the global
list of zones you use 'zhead'.
Example: zoneptr := zhead();
Zone list command
dilbegin zonelist (arg:string); var z:zoneptr; buf:string; code { z:=zhead(); while (z) { buf:="Name: "+z.name+"&n"; buf:=buf+"Filename: "+z.fname+"&n"; buf:=buf+"Creator: "+z.creators.[0]+"&n"; buf:=buf+"Notes: &n"+z.notes+"&n&n"; z:=z.next; }pagestring (buf,self); quit; } dilend
Messages:
In DIL, a program attached to a unit gets activated when the program receives a message. In order to save CPU usage, there are a number of different message categories which can cause activation of a program. The 'wait()' commands first parameter is an integer, telling what message categories the program should reactivate on. The second parameter is an expression, which also must evaluate to TRUE. 'pause' is just special instances of the 'wait()' command.
Caveat Builder: Whenever you construct the arguments for the wait command, bear in mind that ALL your tests will be executed EVERYTIME a message of the relevant kind comes through. Thus you should keep the length of the activation expression to a reasonable minimum, and you should NEVER use the time-consuming findxxx-functions.
Valid example (That prohibits a player from removing an object): :glue:
wait(SFB_CMD,command(CMD_REMOVE));
u := findunit(activator,argument,FIND_UNIT_IN_ME,null );
if (u != self)
{
goto glue;
}
act("You can't remove $2n, it's sticky.",
A_SOMEONE,activator,self,null,TO_CHAR););
block;
goto glue;
See Also:
<a href="findunit.html">Dil and Findunit()</a>The message categories are as follows:
SFB_CMD Command message
When this flag is set, the program gets activated by all commands (legal or illegal) issued by PC's or NPC's. Moving around is also considered a command.
Assume a janitor executes the command ' Ge all from corpse', And Ge interprets to 'get' then this will occur in the DIL program:
'activator'... is a unitptr to the janitor.
'cmdstr'...... is a string which contains 'get'
'excmdstr'...... is a string which contains 'ge'
'excmdstr_case'...... is a string which contains 'Ge'
'argument'.... will contain 'all from corpse'
command(CMD_GET) will evaluate to TRUE.
SFB_DONE 'Command has now been executed' message
When this flag is set, the program gets activated by all successful commands issued by PC's or NPC's. The 'activator', 'medium' and 'target' special values are used as follows:
'activator'... The PC / NPC which executed the command
'medium'...... The unit which is operated upon.
'target'...... The target of the operation.
For example, assume the player John gives a garlic to Mary the Lumberjack wife. The following values are set:
activator == John (unitptr)
medium == Mushroom (unitptr)
target == Mary (unitptr)
command(CMD_GIVE) will evaluate to true.
You thus know that Mary has in fact received the mushroom. It is NOT possible to block (using the 'block' command) these commands since they have already been executed at the time of notification. In a 'get' command, medium would be a unitptr to where the unit was taken from, and target would be the object which was taken.
See the file commands.txt for a description of how the arguments are set for each command. If you can not find a command in there, just ask to get it implemented. Especially you should pay attention to the non-obvious SFB_DONE command(CMD_AUTO_ENTER).
SFB_TICK Timer message
When this flag is set, the routine gets activated by a "clock". The clock ticks (in 1/4th of a second) are determined by the 'heartbeat' variable.
'activator'... is null.
'argument'.... will be empty.
command(CMD_AUTO_TICK) will evaluate to TRUE.
SFB_COM Combat message
When this flag is set, the routine gets activated whenever a combat is in progress. The unit containing the DIL program needs not be involved in the combat itself:
'activator'... is a unitptr to the PC/NPC about to hit someone else.
'argument'.... is empty.
command(CMD_AUTO_COMBAT) will evaluate to TRUE.
SFB_DEAD Death message
When this flag is set, the routine gets activated when a PC or NPC dies:
'activator'... will point to the PC/NPC that is about to die.
'argument'.... is empty.
command(CMD_AUTO_DEATH) will evaluate to TRUE
The SFB_DEAD message is sent, just as the character dies, while his items are still equipped, just before the corpse is created. The character's '.fighting' field points to his primary opponent, although this person does not necessarily have to be the one that killed him.
This can be exploited by making items wiz invisible (the .minv field) just as the message is received, causing them to stay inside the player rather than being transferred to the corpse. This does both give the ultimate crash protection, as well as a means of letting items, such as bribe items, forever be a part of the player (remember to make it un-wizinvis when the player returns from heaven - players should not have access to items while in heaven).
SFB_MSG User message
When this flag is set, the routine gets activated when a message is passed to it. Messages can be passed with the DIL commands 'sendto' and 'send':
'activator'... is a unitptr to the unit sending the message.
'argument'.... is a string containing possible data from the sender.
command(CMD_AUTO_MSG) will evaluate to true.
Messages are normally not generated by actions performed by the owner of the program. For a program to be able to be aware of messages from the owner, a keyword 'aware' should be listed just after 'dilbegin'.
When a unit is saved, normally, the DIL programs in it would restart when the program is loaded. However it is possible to let DIL programs recall their execution from where they left off when they where saved. This is done by listing the keyword 'recall' after the 'dilbegin'. This is however a bit limited. Only the status of the original template are saved. Not the state inside a template called as a function or procedure from inside the original template. 'secure' and interrupts are not recalled upon loading the template.
Example:
dilbegin recall aware mute(); var i : integer;
code
{
i:=10;
while (i>0)
{
wait(SFB_CMD,command(CMD_SAY) or command(CMD_SHOUT));
exec("emote tries to make a sound, but only blood spurts through"+
"the lips",self);
block;
i := i - 1;
}
i:=10;
while (i>0)
{
wait(SFB_CMD,command(CMD_SAY) or command(CMD_SHOUT));
exec("emote tries to make a sound, but can't",self);
block;
i := i - 1;
}
i:=10;
while (i>0)
{
wait(SFB_CMD,command(CMD_SAY) or command(CMD_SHOUT));
exec("emote tries to make a loud sound, but can't",self);
block;
i := i - 1;
}
quit;
}
dilend
/* When attached to a PC, the pc will be unable to utter a sound the first 10 sound command, and blood will spurt out. The next 10 sound commands, the victim just can't shout. The last 10 sound commands only say will work. In the end, 'quit' removes the program all together. The smart thing is that the 'aware' keyword lets the program receive messages from the owner (player) commands. Secondly, the keyword 'recall' makes sure that the program does not start over, if the victim quits in the middle, but restart at the position it had attained. Do not put in the 'aware' if it is not needed. It saves some interpretation time not having to pass the extra messages. */
SFB_PRE Command preprocessing
When this flag is set, the program is activated by a few special events which can then be blocked or changed. Currently, this event is triggered just prior to a spell being cast, and just prior to any sort of damage being given to a target.
PRE "command(CMD_CAST)"
Assume a a spell is cast from player A on player B with a scroll C.
'activator'... is a unitptr to A.
'medium' ... is a unitptr to C.
'target' ... is a unitptr to B.
command(CMD_CAST) will evaluate to TRUE.
'argument'.... will contain a number followed by any
argument to the spell itself. You should
parse this number, it equals the spell number SPL_XXX.
'power' .... is set to 'HM', i.e. how powerful the spell cast
is going to be. YOu can change this number at will.
If you decide to block the spell, you ought to set it
to -1.
Example: wait(SFB_PRE, command(CMD_CAST));
s := getword(argument); splno := atoi(s);
if (splno == SPL_FIREBALL_3)
power := 0; /* No damage */
...
PRE "command(CMD_AUTO_DAMAGE)"
Assume that damage is given from player A to player B with a sword C.
'activator'... is a unitptr to A.
'medium' ... is a unitptr to C.
'target' ... is a unitptr to B.
command(CMD_AUTO_DAMAGE) will evaluate to TRUE.
'power' .... is set to how much damage will be given. You can change
this number at will, but you should not set it to less
than zero.
'argument'.... will contain three numbers that you must parse to
determine what kind of damage we're talking about.
First number is the attack group, this can be one of
MSG_TYPE_XXX from values.h and/or vme.h.
Second number is dependant on the attack group and
identifies what damage compared to the group. For
example WPN_XXX for weapon group.
Third number is the body hit location, one of WEAR_XXX,
(but not all of them, just hands, feet, legs, body, head,
arms, i.e. the armour positions, not positions like finger
or ear).
Example: wait(SFB_PRE, command(CMD_AUTO_DAMAGE));
s1 := getword(argument); grpno := atoi(s1);
s2 := getword(argument); atkno := atoi(s2);
s3 := getword(argument); hitloc := atoi(s3);
if (grpno == MSG_TYPE_SPELL)
{
if ((s2 == SPL_FINGER_DEATH))
{
act("Your scarabaeus lights up as it protects your life force.");
power := -1;
block;
}
}
...
A note upon activating a DIL program
This is what you can't do:
If a DIL program is already active, e.g. it is sending a message or perhaps using "exec" to perform an action, then it can not be activated. Thus, any active DIL program is unable to catch further messages. Imagine this setting:
You have five program P1..P5. P1 sends a message, which is intercepted by P2. P2 now sends a message, but since P1 is busy it can not process the message. P3..P5 are however possible candidates. Assume P3 sends a message, and P4 acts upon it. P4 now sends a message and the ONLY program which can catch it is P5, since all the other programs are "busy". If P5 sends a message no-one can act upon it. When P5 returns, so does P4, P3, P2 and finally P1.<IMG SRC="../images/backgr/waveline.gif" BORDER="0" HEIGHT="18" WIDTH="100%">
Built-in Variables:
'cmdstr'This variable is a string which contains the "command" which was entered by a player. The result of adding:
cmdstr + " " + argument
is the entire string as entered by the player. The 'cmdstr' is EXPANDED by the interpreter, so assume a player types 's' then the string is expanded to 'south'.'excmdstr'
This variable is a string which contains the "first string" which was entered by a player. The result of adding:
excmdstr + " " + argument
is the entire string as entered by the player. The 'excmdstr' is not EXPANDED by the interpreter, but it is converted to lower case. So assume a player types 'S' then the string is returned as 's'. The 'excmdstr' is however changed to all lower case if you don't want this see 'excmdstr_case'.'excmdstr_case'
This variable is a string which contains the "first string" which was entered by a player. The result of adding:
excmdstr_case + " " + argument
is the entire string as entered by the player. The 'excmdstr' is not changed in anyway from how a player types it. If a player types 'S' then the 'excmdstr_case' will have 'S' in it.
'self' This variable is a unitptr to the unit owning the DIL program. For C++ people, this is like the 'this' pointer. For example, if Mary has a program, then self.title equals "Mary the Lumberjack wife"
'activator' This variable is a unit pointer to the unit which activated the DIL program. It is set if 'activator' issued a command or unknown command and the program was setup to catch it, with : wait (SFB_CMD...). See description of messages for more information.
'target' This variable is a unit pointer to the unit which is the target of the current operation. For 'done' messages this could for example be the destination in a give command. See description of messages for more information.
'medium' This variable is a unit pointer to the unit which was used during an operation. For 'done' messages this could for example be a bag which was the medium in a get operation. See description of messages for more information.
'power' This variable is an integer which can be reassigned. It is used in permission messages and in a few done messages. For example a permission request to damage a person with 100 damage would have power equal 100. This could then be reduced to 50 by assigning a new number. See description of messages for more information.
'argument' This variable is a string, showing the argument of a command resulting in the activation of the DIL program. See SFB_CMD for example.
'heartbeat'
This is the DIL programs heartbeat. It can be assigned runtime to
change the rate with which SFB_TICK is activated. Do not set it
too low, and remember that it is specified in 1/4th of a second.
use the constant PULSE_SEC to multiply your wanted delay, for
Example:
heartbeat := PULSE_SEC*25; /* Tick every 25 seconds */
'null' This is a null pointer.
'weather' This is the state of the mud-weather. It will equal one of the SKY_XXX values in values.h and/or vme.h.
'realtime' This variable returns the number of seconds passed since 1970 something. For C buffs this is equivalent to time(NULL).
'mudday' 'mudhour' 'mudmonth' 'mudyear' These variables lets your program keep track of the time in the mud. They all have integer types.<IMG SRC="../images/backgr/waveline.gif" BORDER="0" HEIGHT="18" WIDTH="100%">
DIL constructs:
DIL offers a set of construct for you to program with.
<a name ="dcif">
if:
The if statement is much like C. It takes any type as
argument. Non integers are considered 'TRUE' if they are
not null.
Example:
dilbegin foo();
code
{
if (self.hp>10)
{
exec("say Hehe!",self);
}
else
{
exec("say ouch!", self);
}
}
dilend
Example:
dilbegin foo();
code
{
if (self.loaded>10)
{
exec("say its getting crowded!",self);
}
}
dilend
Example:
dilbegin foo();
code
{
if (self.loaded<10)
exec("say plenty of room!",self);
}
dilend
goto:<a name ="dcgoto">
The goto statement lets you jump about in the code.
Labels in your DIL programs, for 'goto' or interrupts
are defined within ':'. For an example, see the program below.
Example:
dilbegin foo();
code
{
:mylabel:
exec("say Hello world",self);
pause;
goto mylabel;
}
dilend
while:<a name ="dcwhile">
The while statement lets you execute a series of
statements while an expression evaluates to TRUE.
Example:
dilbegin foo();
code
{
while (not self.inside) {
exec("say I own nothing", self);
pause;
}
exec("say ahh.. now i own something", self);
}
dilend
break: <a name ="dcbreak">
The break statement makes you break out of any
loop you're currently in.
Example:
dilbegin foo();
code
{
while (self.inside) {
if (self.position < POSITION_SLEEPING)
break;
exec("say I own something", self);
pause;
}
}
dilend
continue:<a name ="dccont">
The continue statement makes you jump to the top
of any loop you're currently in.
Example:
dilbegin foo();
code
{
while (self.inside) {
if (self.position < POSITION_SLEEPING)
break;
pause;
if (self.hp<0) continue;
exec("say I own something", self);
pause;
}
}
dilend
on n goto la, lb, ..., ln:
This construct is an easy way of performing a goto operation
based on the result of an integer. The integer value 'n' must
be zero or positive and less than the number of labels specified
in the label-list. If n is outside this range, the on-goto operation
is skipped and execution continues at the next instruction.
Based on the value of 'n' execution continues at the label
corresponding to number 'n' in the list. I.e. if n is 0, then
execution continues at the first specified label, if n is 1
then at the second, etc. etc.
Example:
Assume you have an integer 'i' larger than zero, which takes
on 0, 1, 2, 3, 4 or 5. Based on each value you need to take a
different action, this is how you can do it:
on i goto grin, laugh, grin, nada, poke, laugh;
log("Value was not in the range 0..5");
quit;
:laugh:
exec("grin", self);
goto ...;
:grin:
exec("cackle", self);
goto ...;
:blank:
exec("cry", self);
goto ...;
:poke:
exec("smirk", self);
goto ...;
It is often used in this context
on rnd(0,4) goto l1, l2, l3, l4, l5;
:l1:
bla;
:l2:
bla;
....
foreach:
Foreach is an easy way to process all the units in the
local environment relative to the 'self' executing the
foreach. Foreach takes care of creating a list of local
units, and of securing them. You can use both break and
continue in a foreach statement. The unit executing the
foreach ('self') is always a part of the foreach.
It is important to understand that the units in the local
environment are relative to the 'self' executing the foreach.
Example:
This foreach is copied onto the spell caster, and hence all units
relative to the spell caster (i.e. self) are processed in the foreach.
Assume that it was executed on the spell caster's staff, then all units
found would be relative to the staff, i.e. the spell caster's inventory.
...
foreach (UNIT_ST_PC|UNIT_ST_NPC, u)
{
if (u.hp < u.max_hp)
{
act("Warm raindrops fall upon you, cleaning your wounds.",
A_ALWAYS, u, null, null, TO_CHAR);
u.hp := u.hp + 6;
if (u.hp > u.max_hp)
u.hp := u.max_hp;
}
else
act("Warm raindrops fall upon you.",
A_ALWAYS, u, null, null, TO_CHAR);
pause;
}
...
<IMG SRC="../images/backgr/waveline.gif" BORDER="0" HEIGHT="18" WIDTH="100%">Assignment:
You can assign values to the variables you declare
in your 'var' section, and some of the built-in
variables. This is done by the ':=' operator.
Note that you can also assign a variable the result
of an expression
(the addition of strings below as an example)
Example:
dilbegin foo();
var
myvarsl : stringlist;
myvars : string;
code
{
:start:
myvarsl := {"a string","another","the first"};
myvars := self.name+" XX ";
myvarsl.[2] := "the last";
myvarsl.[3] := "illegal"; /* Will not work since [3] is not defined */
pause;
goto start:
}
dilend
<IMG SRC="../images/backgr/waveline.gif" BORDER="0" HEIGHT="18" WIDTH="100%">
<a name ="express"> Expressions: The expressions used in assignment can return any of the types you can declare variables. Also they might return fail or null. An expression returning fail will not result in any action being taken. Fail is returned when you request a field from a null pointer, or the like.
Example:
dilbegin foo();
var
myvarsl : stringlist;
myvars : string;
myvarint : integer;
myvaredp : extraptr;
myvarunit : unitptr;
code
{
:start:
myvarunit := self.inside.next;
myvarsl := {"a string","another","the last"};
myvars := self.name+" XX "+itoa(self.hp);
myvarint := activator.hp;
myvaredp := "Rabbit Stew Complete" in activator.quests;
pause;
goto start:
}
dilend
<a name ="ops">
Operators:
DIL features many other operators. For integers, '<', '>', '<=', '>=', '!=' '==' signify less than, greater than, less or equal, greater or equal, not equal, and equality operators. Furthermore, you can compare strings with '==' or '$=' for equality test, and '!=' for non equality. Pointers may also use '==' and '!=' and you may force DIL to compare pointers, even for strings with the '#=' pointer-equality operator. The '$=' and '#=' is considered obsolete, and only used for backward compatibility.
<a name ="ein">
in: The special operator 'in' is a multipurpose operator for a lot of things. It allows you to search through quests and extra descriptions, stringlists and search for words in strings.
<a name ="esins">
string 'in' string Argument 1: A string to find. Argument 2: A string to search. Return: TRUE, if first string is found in second string.
Example:
dilbegin foo();
code
{
if ("guard" in activator.title)
exec("say hello guard",self);
pause;
}
dilend
<a name ="esinsl">
string 'in' stringlist
Argument 1: A string to find.
Argument 2: A stringlist to search.
Returns: 1.. if first string is found in stringlist, or 0 if it is
non existent. If found the number equals the index of the
string found plus one.
Example 1:
s := "c";
sl := {"a","b","c","d"};
i := s in sl;
The result of 'i' is 3, and sl.[i-1] equals "c" (s).
Example 2:
dilbegin foo();
code
{
if ("james" in activator.names)
exec("say hello james.",self);
pause;
}
dilend
<a name ="esine">
string in extraptr
Argument 1: A string to find.
Argument 2: An extra description list to search.
Return: Extraptr to first entry with string matching .names or
null if none. (names must be exact letter by letter
match, although case is ignored).
Example:
dilbegin foo();
code
{
if ("Rabbit Stew Complete" in activator.quests) {
exec("say wow!, you helped Mary get her stew!", self);
exec("app ", self);
}
pause;
}
dilend
<IMG SRC="../images/backgr/waveline.gif" BORDER="0" HEIGHT="18" WIDTH="100%">
<a name ="funcs">
Functions:
DIL features an extended set of built-in functions for extended program control. Built-in functions can be part of any expression in DIL. The built-in functions are listed later.
Example:
dilbegin foo();
code
{
exec("say I exist in "+itoa(self.loaded)+"copies", self);
pause;
}
dilend
DIL also lets you use templates as functions, but in a limited way. Using templates as functions, you may only use the return value to assign it to one of the variables declared in the 'var' section. No fields.
Example:
dilbegin integer bar(s:string);
code
{
exec("say "+s,self);
return rnd(1,10);
}
dilend
dilbegin foo();
external
integer bar(s:string);
var
myint:integer;
code
{
myint := bar("rolling the dice.");
exec("say I rolled a "+itoa(myint));
pause;
}
dilend
quit: This simple command quits the entire DIL program, even if called while inside a procedure or function.
return: Return from a call to a procedure template (no return type declared). The execution continues from where the procedure was called.
return():
Return from a call to a function (return type declared). The expression inside the parenthesis evaluates to the value returned.
DIL also allows for game-time *symbolic* resolving of function/procedure names. This allows you to pass template names as string arguments and call them in your program. This kind of function call requires taxing look ups and type check runtime, so use the normal kind of procedures if possible.
In effect, the syntax of a symbolic call is similar to that of a normal, except you use a string variable as function name instead of the real function name. If the string variable contains a valid reference to a procedure/function, and all the argument types matches the found templates argument types, the call is made. Otherwise, the call is skipped. Note that you will get no type check by the compiler when using symbolic references.
<IMG SRC="../images/backgr/waveline.gif" BORDER="0" HEIGHT="18" WIDTH="100%">
<a name ="fields">
Fields:
The 'extraptr' and 'unitptr' types contain information which is available to you by using fields. For example (self is a unitptr), self.inside is a unitptr to what is inside the 'self' unit. (Hence '.inside' is the field). And self.inside.outside is a unitptr to self (assuming that something is actually inside self, otherwise self.inside would evaluate to null). Some fields may not be changed by DIL programs directly but must be modified indirectly using certain procedure calls in DIL. Others may not be changed at all. All are readable for DIL programs.
The extraptr structure is used for several things. The primary is extra descriptions for units, and quest data. Keywords in the 'names' field and the actual description/data in the 'descr' field.
In the following (RW) means the value may be assigned new values by DIL, while (RO) means the the value only can be read. A (RO) value might be possible to change through built-in functions/procedures

The following are definitions and documentation for the built-in functions in DIL. The definitions are not definitions 'as such', but serve to distinguish arguments in the documentation below.
string asctime(i : integer) i : the time to convert in seconds (<a href = "#bvrealtime">realtime</a> variable)
Returns: The seconds converted into an ascii format date of the following
form "Mon Nov 18 18:49:08 1996"
Example:
log(asctime(realtime));
</PRE
Function: integer strcmp( s1:string, s2:string) ;
s1
if (strcmp("I Care about Capitals",s2)==0)) { sendtext ("You care I can see.&n",self); quit; }
Function: integer strcmp( s1:string, s2:string l :integer) ;
s1
if (strcmp("Mark Carper",s2,4)==0)) { sendtext ("Hi Mark how is it going?&n",self); quit; }
string textformat(s : string)
s : The text string to format. The string is formatted according to
the escape format codes as defined in one of the other documents.
Returns: The formatted string which will automatically adapt to each
individual player's settings.
Example:
ts := note.extra.descr;
rs := textformat(ts);
integer spellindex(s : string) s : The abbreviated or full spell name
Returns: -1 if no such spell, otherwise it returns the spell index
for that spell.
Example:
s := "cu li wo"; /* cure light wounds */
i := spellindex(s);
string spellinfo(idx : integer, i1 : integer, i2 : integer, i3 : integer,
i4 : integer, i5 : integer, i6 : integer, i7 : integer, )
idx : The spell index (SPL_XXX). You might want to use spellindex
to find this value.
Returns:
The full name of the spell, or the empty string if no such spell.
All the integer parameters are set to the following values:
i1 : Spell realm (MAG / DIC)
i2 : Spell sphere (SPL_XXX)
i3 : Mana usage
i4 : 0 if a non-offensive spell, non-zero otherwise
i5 : Resistance required (SPLCST_XXX)
i6 : Mediums (MEDIA_XXX)
i7 : Targets (FIND_UNIT_XXX & TAR_XXX)
Example:
s := "cu li wo"; /* cure light wounds */
i := spellindex(s);
s := spellinfo(i, i1, i2, i3, i4, i5, i6, i7);
/* s & i1 - i7 now set */
</a>
Function: beginedit ( u : unitptr);
u
dilbegin edextra (); var temp:string; code { beginedit (self); wait(SFB_EDIT,self==activator) ; temp:=textformat(argument); addextra (self.extra,"general",temp); quit; } dilend
The previous DIL is an example of how you could make a command to set the general extra which is the characters description when you do 'look player'
integer can_carry(ch : unitptr, u : unitptr, n : integer) ch : The character to check u : The unit to check if he can carry. n : How many copies of that unit.
Returns: 0 if 'ch' can carry 'n' times 'u'.
1 if 'n' items are too many (his hands are full)
2 if 'n' times 'u' are too heavy
Example:
i := can_carry(activator, item, 1);
if (i == 1)
exec("say Your hands are full!", self);
else if (i == 2)
exec("say You cant carry that much weight.", self);
else
exec("give "+item.name+" to "+activator.name, self);
string fits( char : unitptr, obj : unitptr, pos : integer ); char: Character which we want to test if obj can be fitted upon obj: The object we want to see if fits char. pos: -1 or WEAR_XXX Returns: Empty string if ok, or a textual description of the size problem.
Fits tests if "obj" can be worn by "char" in position "pos". If pos is -1, then fits automatically figures out the default worn position for "obj".
Example:
s := fits(self, obj, -1);
if (s != "")
exec("say Don't buy it, its "+s, self);
Function: string replace( t :string, n : string, o : string);
t"Jafar %t% %l%" := replace(%n%,pc.name,"%n% %t% %l%");
"Jafar the human %l%" := replace(%t%,pc.title,"Jafar %t% %l%");
"Jafar the human 1" := replace(%l%,itoa(pc.vlevel),"Jafar the human %l%");
</A>
Function: unitptr restore( filename : string , u : unitptr );
filename
dilbegin chest_load (); var waist:unitptr;/*to hold the null returned in this example*/ chest:unitptr;/*pointer to the storage chest*/ code { chest:=load ("chest@myzone");/*get the container*/ if (chest==null) { log ("Error");/*log an error*/ quit; }waist:=restore("chest."+self.zoneidx,chest); /* restore given filename into chest waist can be ignored in this dil since it is not used. */ link (chest, self);/*link chest into room*/ quit;/*dil load routine done destroy self.*/ } dilend
Example 2:
dilbegin chest_load (); var chest:unitptr;/*item to be loaded*/ code { chest:=restore("chest."+self.zoneidx,null);/*restore into chest*/ if (chest== null)/*see if something was restored*/ chest:=load("donate_chest@"+self.zoneidx); /*load a new one if there is nothing restored*/link (chest, self);/*link item into room*/ quit;/*destroy the load dil.*/ } dilend
Note: Example 1 is to be used if 'storall' was used not storing a container. Example 2 is for items stored with 'store' with the container saved as well. See Also <A HREF="#bpstore">Store a Unit to a Unit file</A> and <A HREF="#bfdelunit">Delete a Unit file</A>.
integer meleeattack ( ch : unitptr, vict : unitptr,
bonus : integer, wtype : integer )
ch : The character which should make an additional attack.
vict : The victim of the attack.
bonus : Any penalty or bonus added to the attack.
wtype : The weapon type of the attack, if a valid type then that is
used for the attack purpose, otherwise the default weapon/hand
attack is used.
result: 'ch' performs a melee attack (using whatever weapon is wielded
or his bare hands) against 'vict'. Returns the amount of damage
given (-1 is failed).
If wtype is within a valid weapon range (WPN_XXX) any weapon will be bypassed, and the value will be used as the attacktype. Good for things like "meleeattack(ch, vict, bonus, WPN_CIRCLE_KICK)" if you want person to be able to perform an extra attack even though wielding a weapon or something. Note that this will require BOTH a weapon type WPN_CIRCLE_KICK and a skill "kick" in order for it to work.
Function:
meleedamage ( c : unitptr, v : unitptr, b : integer, wt : integer );
cdilbegin kick(arg : string); external provoked_attack (victim : unitptr, ch : unitptr);

Function: string mid ( o : string, s : integer, e : integer );
o"rock" := mid ("sprocket",3,6);
string moneystring(amt : integer, verbose : integer)
amt : The amount of money
verbose: True if an expanded string (copper pieces) or false
if abbreviated money types (cp).
result : The moneystring for the given currency.
unitptr equipment ( u : unitptr , i : integer )
u : The character to search.
i : What equipment to find, any of the WEAR_XXX macros.
result: Returns the unit on 'u' which is equipped on position 'i'.
See WEAR_* in values.h and/or vme.h
Function: string tolower ( s : string );
s"hello!" := tolower("HELLO!");
Function: string toupper ( s : string );
s"HELLO!" := toupper ("hello!");
integer visible(u1 : unitptr, u2 : unitptr) u1: The character who is looking at u2 u2: The unit which the character u1 is trying to see. return: TRUE if u1 can see u2, FALSE otherwise. Example: if (visible(self, victim)) ...
integer opponent(u1 : unitptr, u2 : unitptr) u1, u2: Two characters return: TRUE if u1 is in combat with u2, FALSE otherwise. Example: if (opponent(self, victim)) ...
When in a combat, you are usually only melee-attacking one opponent, although you may have many other opponents. This function lets you check if you are directly / indirectly an opponent to another unit.
integer purse(u : unitptr, coinage : integer)
u : The unit to check
coinage: The money type (e.g. gold, silver), one of IRON_PIECE, etc.
Returns: The number of such units found.
Example: if (purse(self, PLATINUM_PIECE) > 10)
exec("say I am loaded with platinum!", self);
integer atoi ( s : string )
s : A string with a number.
return: The number in the string.
Example: i := atoi("42");
Function: integer check_password( u : unitptr, s : string ) ;
uif (not check_password(pc,arg)) { sendtext (arg+" is not "+pc.name"'s password.",self); quit; }
integer command ( cmd : string or integer )
cmd : A string of the full typed command, e.g. "push" or "say".
Alternatively you can specify one of the macros defined in
values.h and/or vme.h, e.g. CMD_SAY
return: Whether the command specified by the activator is the one of
the argument.
It is noteworthy, that unlike simple compares like this;
if ("spook" in cmdstr) {
...
...
}
or
if (cmdstr == "spook") {
...
...
}
where the first will activate even if the cmdstr is "nospook", and the second only if cmdstr equals the word "spook" to the letter, the following construct will activate as long as the contents of cmdstr doesn't conflict with cmd;
if (command("spook")) {
...
...
}
ie, it will receive the same kind of treatment as a 'regular' command. That means that you provide ease of use to the user (allowing shorthand notation), while securing that you're doing what the user wants.CAVEAT Builder:
If you use a string argument as cmd, be sure that there are no white-space in it, ie, that the argument does only consist of letters.
Example:
command("spook");
is a valid string, while this construct;
command("spook him");
is NOT valid. The reason of that is that cmdstr only contains the
FIRST word of the input from the player, and thus the latter
construct could never evaluate to true. This should be evident
taking the above information into account, as "spook him" could
never equal "spook" (which would indeed be the text in cmdstr
if the player entered the string "spook him".)
Function: integer delstr( filename : string ) ;

integer dildestroy( s : string, u : unitptr )
s : name of dil template to delete.
u : unit to remove program from.
return: Whether a program using a template with same name as in 's'
attached to unit 'u' was deleted.
integer dilfind( s : string, u : unitptr )
s : name of dil template to find.
u : unit to find program in.
return: Whether a program using a template with same name as in 's'
attached to unit 'u' was found.
string itoa ( i : integer ) i : A number. return: A string with the number. Example: s := itoa(42);
integer isaff ( u : unitptr , i : integer ) u : A unit to be examined. i : An id of an affect, see ID_* in values.h and/or vme.h return: TRUE, if unit 'u' is affected by affect id 'i'
Function: integer islight ( u : unitptr )
uFunction: integer isplayer( pcname : string ) ;
pcname
if (not isplayer(arg)) { sendtext (arg+" is not a character.&n",self); quit; }
integer isset ( i : integer , bit : integer ) i : An integer to examine. bit : A set of bits to match. return: TRUE, if bits in 'bit' is set in 'i'. Example: if (isset(self.manipulate, MANIPULATE_TAKE)) ...
integer paycheck( u1 : unitptr, u2:unitptr) u1 : unit to check against u2 : player to check access for return: TRUE if the player u2 has pay access to the location in which the unit u1 is located. FALSE if the player does not have access. Using non-players as u2 will return TRUE. The function checks if the player has pay-access (if needed) to the zone in which u1 is located.
unitptr findunit ( u : unitptr , s : string , i : integer , l : unitptr )
u : The unit the local environment is relative to.
s : A string with name of the unit to find.
i : The environment, where to look for it, see FIND_UNIT_*
in values.h and/or vme.h.
l : An optional list of units to search.
return: If the unit is found, the function returns that unit.
Returns null if nothing found.
The first argument is typically the char that's looking for something, i.e. if Mary needs a spoon to stir the pot, she'll be the first argument.
The second argument is what you're looking for, represented by a string. In the above mentioned example, that'd be "spoon".
For the second or third argument, you have a choice, as you'll only need to use one of them, and let the other be 0 or null. For instance, if you have a pointer to Mary's kitchen utensil pot, you can use the line:
findunit(mary, "spoon", 0, pot);
Or you can just let her look around for it with:
findunit(mary, "spoon", FIND_UNIT_INVEN or FIND_UNIT_SURRO, null);
You can use all the FIND_UNIT_ values defined in values.h and/or vme.h, if you want to look for something for example within the zone (FIND_UNIT_ZONE), the entire world (FIND_UNIT_WORLD) (you rarely need to do that, it's mainly for tell etc.), or just the inventory or equipment of the char in question (FIND_UNIT_INVEN and FIND_UNIT_EQUIP). Finally, as in the example above, you can look in the room of the char (FIND_UNIT_SURRO).
Using FIND_UNIT_PAY or FIND_UNIT_NOPAY in this function will be ignored. The flags for findunit, intuitively:
FIND_UNIT_EQUIP:
The objects you will see with `equipment' Assumes first argument to findunit is a char.
FIND_UNIT_INVEN:
The objects you will see with `inventory' or `look in bag'
FIND_UNIT_SURRO:
The objects you can see, and get with `get', or the characters you can `poke' :-)
FIND_UNIT_ZONE: As FIND_UNIT_WORLD, only more local.
FIND_UNIT_WORLD: Any object in the entire world. Does NOT start looking close to the object of findunit's first argument, but rather somewhat randomly.
On top of these, the following (new) values are defined:
FIND_UNIT_IN_ME:
Anything inside of the object of the first argument.
FIND_UNIT_HERE:
Anything `here', i.e. in object or around it (same as IN_ME + SURRO)
FIND_UNIT_GLOBAL: ANYTHING, starting close to object and working out.
unitptr findrndunit( u : unitptr, sv : integer, uf : integer) Returns: A pointer to a random unit, or null u : The unit pointer which the search is relative to. sv : The search-location, a value (not bit vector) of FIND_UNIT_XXX uf : Bit vector. The unit flags which can match of UNIT_ST_XXX
Example: u := findrndunit(self, FIND_UNIT_ZONE, UNIT_ST_PC|UNIT_ST_NPC);
This routine returns a random unit. Notice how the 'uf' lets you specify exactly what unit types to look for. The 'sv' is not a bit vector, although FIND_UNIT_XXX is usually used as such. If you need to search multiple environments, then call the routine once for each.
Using FIND_UNIT_PAY or FIND_UNIT_NOPAY in this function will pick a random player which in addition to being in the search environment also is registered as valid payer (or not). Asking for a room would yield a random room registered to be accessible for paying players only (or not). Asking for objects would return no unit (null).
</A>
Function: integer filesize ( filename :string);
file
dilbegin notebook (); code { ns := filesize (self.name+"notebook"); if ( ns >500000) { sendtext ("Your notebook is full.&n",self); quit; } else if ( ns > 250000) { sendtext ("Your notebook is more than half full.&n",self); quit; } else if (ns >125000) { sendtext ("Your Notebook is only 1/4 full.&n",self); quit; } else if (ns >0) { sendtext ("Your notebook is less than 1/4 full.&n",self); quit; } else { sendtext ("You don't have anything in your Notebook.&n",self); quit; }} dilend
The previous DIL example shows how you could use the 'filesize' instruction to check the size of a player stored notebook.
unitptr findroom ( s : string )
s : Symbolic name of room.
return: A pointer to the room, or null
Example: findroom("inn@udgaard")
unitptr findsymbolic ( s : string )
s : Symbolic name of the NPC or Object to find.
return: A pointer to an instance of the unit, or null.
Example: findsymbolic("bread@midgaard")
This routine supplements findroom and findunit. It comes in handy,if it is
important to get a correct reference to a NPC in the world. If for example,
Mary needs to send a message to John the Lumberjack, then she should NOT
use the findunit() since it may locate a different John - even a player!
If she instead locates him using findsymbolic("john@haon_dor") she will be
certain that it is in fact her husband, and not the player John Dow from
Norway. It will NOT locate rooms, for the only reason that findroom is a
lot more efficient.
unitptr findsymbolic ( u : unitptr, s : string, i : integer ) u : Search is relative to this unit. s : Symbolic name of the NPC or Object to find. i : FIND_UNIT_XXX bit vector of places to search. return: A pointer to an instance of the unit, or null. Example: findsymbolic(self, "bread@midgaard", FIND_UNIT_INVEN)
This routine supplements findroom, findunit and findsymbolic(#). It comes in handy, if it is important to get a correct reference to a unit somewhere relative to 'u'. If for example, Mary needs to check if she has her own cooking pot, then she should NOT use the findunit since it may locate a different pot, not belonging to Haon-Dor but to some other zone. If she instead locates it using findsymbolic(self, "pot@haon_dor", FIND_UNIT_IN_ME) she would be certain that it is in fact her own cooking pot that she is carrying around, and not some other pot from a Joe Blow's zone.
Function: flog (filename : string, s : string, wa : string );
filename
dilbegin zonelog (s:string); code { flog (self.zonidx+".log",s,"a"); return; } dilend
The previous DIL function will work in any zone to log to a file with that zones name each zone could use it to keep zone logs separate.
string getword ( var s : string ) s : A string with zero or more words separated by space. return: The first word of the string.
NB: The argument string has the returned word removed.
stringlist getwords ( var s : string )
s : A string with zero or more words separated by space.
return: A stringlist where each string was a word in 's'.
unitptr ghead ( )
return the first unit in the global list which will be the last char to have logged on.
stringlist split ( var s : string, var t : string)
s : A string with zero or more words separated by var t.
return: A stringlist where each string was a word in 's'
separated by string 't'.
You can use '&x' to split a string by line. This is very usefull when reading in files with 'loadstr'.

Function: string left ( o : string, l : integer );
o"short" := left ("shorten me",5);

integer length ( a : string or stringlist )
a : a string or stringlist to examine.
return: The length of the string in characters, or the number
of strings in a list.
unitptr load ( s : string )
s : Symbolic name of unit.
return: A pointer to the unit, or null
Example: load("garlic@midgaard")
The loaded unit is automatically placed inside the object
which loaded it. Use for example the link command to move
it into other units.
</A>
Function:
integer loadstr( filename : string , buff : string );
filenameFILE_LOADED, FILE_NOT_FOUND, FILE_OUT_OF_MEMORY,or FILE_TO_LARGE
Loadstr is used to load strings from disk that were saved either by savestr
or any text editor.
The 'loadstr' is perfect for operations such as
on-line edited newspaper, a lottery where the tickets are sold to players,
creating smarter NPC's that can remember through reboots who they are hunting,
Dil based teachers, message boards, mail system, news command., zone or
room based help, competition boards, and much much more.
Disk access is always slow.
attempt to keep file sizes to a minimum for quick loading. Otherwise you
might cause serious delays on the server.
Example:
dilbegin news_load (); var ret:integer;/*to hold the return value if loaded or not*/ buff:string;/*to hold the loaded string*/ code { ret:= loadstr("news.txt",buff); if (!ret) { log ("File not read."); quit; }sendtext(buff+"[&]n",self); quit;/*dil load routine done destroy self.*/ } dilend

<A HREF="#bfdelstr">Delete a String file</A> and
<A HREF="#bfsavestr">Save String file</A>
integer openroll( dice : integer , end : integer )
dice : The size of the dice being rolled.
end : The margin for the open-ended roll.
return: A random integer in approximately +/- 2^31 in worst case.
Example: i := openroll(100,5); The "100" roll continues on values
96 - 100 and on values 1 - 5.
integer pathto( from : unitptr, to : unitptr )
from : The unit which the path is taken from
to : The unit which the path is taken to
returns: DIR_XXX from values.h and/or vme.h.
Example: i := pathto(self, findroom("inn@midgaard"));
pathto(buff : string, u : unitptr ) buff : The string that is to be paged to the player. u : The unitptr the buff is to be paged for. returns: nothing example: pagestring (buff,self); would format the buff string to the player so the buff text doesn't scroll off the screen until after the player presses enter.
Function: string right ( o : string, r : integer );
o"Easy" := right ("This is Easy",4);
integer rnd ( i1 : integer , i2 : integer ) i1 : Start of range. i2 : End of range. return: A random integer in an interval from 'i1' to 'i2'. Example: i := rnd(1,10);
Built-In Procedures:
DIL features some built-in procedures that allows you increased control over in-game data structures and event handling. Once such procedure (used above)is 'exec()'. The inline procedures are used as any other procedure by typing its name, followed by a list of argument expression enclosed in parentheses. The return types of the expressions used for built-in procedure calls are checked by the compiler.
DIL also lets you call templates defined in the current or other zones. The naming of templates follows the normal naming convention for zone, using the 'name@zone' as a symbolic name for a procedure. Before being able to use external procedures, you must define their name and type in a separate 'external' section in the template. The declaration in the 'external' section should match the original declaration of the referenced program. You can define the number and type of arguments the template take, by listing them inside the declaration parenthesis (as well as in the original declaration of that template) (see example below) Example:
dilbegin bar(s:string);
code
{
exec("say "+s,self);
return;
}
dilend
dilbegin foo();
external
someproc@hades1();
bar(s:string);
code
{
someproc@hades1();
bar("Hello "+activator.name);
pause;
}
dilend
When the procedure is called, the argument expressions are calculated, and
passed to the template. Built-in procedures, their arguments and function
are listed later.
The following are definitions and documentation for the built-in procedures in DIL. The definitions are not definitions 'as such', but serve to distinguish arguments in the documentation below.
follow( f : unitptr, m : unitptr ) f : The character to follow m : The character to be followed
Unconditionally makes 'f' follow 'm', even if 'f' is mortally wounded, sleeping, fighting or whatever.
</a>
Function: flog (filename : string, s : string, wa : string );
filename
dilbegin zonelog (s:string); code { flog (self.zonidx+".log",s,"a"); return; } dilend
The previous DIL function will work in any zone to log to a file with that zones name each zone could use it to keep zone logs separate.
logcrime( c : unitptr, v : unitptr, t : integer ) c : The criminal (main suspect) v : The victim t : The crime type (CRIME_XXX)
Registers a crime committed against 'v' by 'c'. Use the
CRIME_XXX values from values.h and/or vme.h as the 't' argument.
The logcrime routine automatically registers group members
of the criminal, etc. In stuff like steal, remember to make
the criminal visible if he fails his attempts.
acc_modify( u : unitptr, i : integer )
u : A player
i : An amount in 1/100s, for example 100 would equal $1.00, and
-100 would equal -$1.00.
Access only allowed with 'root' access and all transactions are
registered in the specially encrypted account log file. Use with
great caution, and always test thoroughly before using.
Use without prior permission may cause deletion of god / zone.
</A>
Function: stringlist strdir( match : string ) ;
match
"corpse*" matches: corpse.10938 corpse.whistler corpseofwhistler ... "corpse?" matches corpse1 corpses corpse5 ... "[abc]*" matches ability about cost back ... "[a-z]*" about zoo man father ... "start[nm]end" matches startnend startmend
Example DIL:
dilbegin wanted (); var wantedlist:stringlist; templist:stringlist; i:integer; ln:integer; code {
wantedlist := strdir ("dead*");
i := 0; ln := length (wantedlist);
while (i < ln ) { templist := split (wantedlist.[i],"."); sendtext (templist.[1]+" wanted dead!&n",self); i:=i+1; }
quit; } dilend
The previous DIL would be an example of a command to check the wanted dead players on the VME if you saved the files with the first word being 'dead' and separated it with a '.' and the players name. For example if 'whistler' was wanted dead the file name would be 'dead.whistler'
Function: set_password( u : unitptr, s : string ) ;

u
dilbegin save_contents (); code {:start: wait (SFB_CMD,command ("store")); wait for the store command*/ block; store("chest."+self.zoneidx,self,FALSE);/*store everything inside self.*/ goto start; } dilend
Example 2:
dilbegin save_container_n_contents (); code {:start: wait (SFB_CMD,command ("store")); wait for the store command*/ block; store("chest."+self.zoneidx,self,TRUE);/*store everything inside self and self.*/ goto start; } dilend
See Also <A HREF="#bfrestore">Store a Unit to a Unit file</A> and <A HREF="#bfdelunit">Delete a Unit file</A>.
position_update ( u : unitptr )
u : A pointer to a player or a monster. The character will be
updated and perhaps killed, incapacitated, mortally
wounded, revived, etc. depending on current hitpoints.
Useful when tampering with the 'hp' field. Example:
pc.hp := pc.hp - 100;

Function: gamestate( u : unitptr, gs : integer );
Change the gamestate of a unitptr, uses the GS_ defines from the
vme.h. This is used on the log on menu of the VME 2.0 release. Which is
shown here as an example but it can also be used in a command. When used it
removes the char from playing so be aware that players could use this to hide
if you run a player killing style mud.
Example:

Look in vme.h for the possible values you can send to the menu function.
addextra ( var e : extraptr, l : stringlist , s : string ) e : Extra description list to add element to. l : Stringlist for the .names field. s : String for the .descr field. result: Adds an extra description to a list of extra descriptions.
CAVEAT builder: You cannot use an extraptr variable as the e argument, but you may continue to use the following form:
... ... addextra (self.quests, "Bozo's Quest"); ... ...
addstring ( var l : stringlist, s : string ) l : Stringlist to add string to. s : String to add. result : Adds a string 's' to a stringlist 'l'.
subextra ( var e : extraptr, s : string ) e : Extra description list to remove element from. s : String matching .names field in element result: Removes first extra description from list with matching name.
<emp>CAVEAT</EMP> builder: You cannot use an extraptr variable as the e argument, but you may continue to use the following form:

walkto ( u : unitptr ) u : Room to walk to. result: Makes unit (self) walk to room, taking a 'step' at each 'tick'.
Example:
walkto(findroom("inn@udgaard"));
link ( u : unitptr, t : unitptr )
u : Unit to link.
t : Unit to link into.
result: Link a unit into another unit hierarchy. (Automatically
unequipps if equipped).

</A> 4.8 Getting a skills name</A>
Function: string skill_name( i : integer ) ;

Function: reboot ;
This function works like a quit command. Anything after the reboot function in a Dil will not be
executed the mud will reboot instantly. The zone must have root privileges in
the zonelist in order to use this function.
Simple reboot command
dilbegin cmd_reboot (arg:string); code { sendtext ("Rebooting the mud.&n",self); reboot; } dilend
Function: killedit ;
This function is used to kill the editor on a PC if it needs to
stop editing before the PC is done editing. An example of when this is needed
is when a player is killed while editing or is transfered away from a place where he was editing.
You can let them finish but it may be wierd for a person to finish
posting in one room while in another.
Example
dilbegin editextra (arg:string); code { interrupt (SFB_DEAD,self==activator,int_quit); beginedit (self); wait(SFB_EDIT,self==activator) ; temp := textformat(argument); addextra (self.outside.extra ,{"graphitee"},temp); quit; :int_quit: killedit; quit; } dilend
experience ( i : integer, u : unitptr )
i : A integer number of experience to gain or loose.
u : The player to receive the experience.
result: The integer amount of experience is added to the players
total amount of experience (thus causing more or less
experience). USE WITH CARE! SUGGEST THAT YOU ONLY USE
INTEGER CONSTANTS AS THE EXPRESSION TO AVOID ERRORS.
The purpose of act is to send a message to a number of players present in a room. The room is defined as the room containing the afore mentioned character (provided he himself is in the room, i.e. not in a closedcontainer.)
Syntax:
act(message, visibility, char, medium, victim, to_whom); message
A_SOMEONE
A_HIDEINV
A_ALWAYS
A_SOMEONE, except that the receiver
will see the message even when sleeping.
char
TO_ROOM
TO_VICT
TO_NOTVICT
TO_CHAR
TO_ALL
TO_REST
Act Formatters
Just as the description formatters, act has its own set of formatters that enable you to create generic messages that will be interpreted at run-time, lessening the load on you.
The format string is a normal message, containing some special characters:
'$$'
The numbers:
'1'
The characters
'N'
exec ( s : string , u : unitptr )
s : Command and arguments to perform.
u : Unit to perform command.
result: Unit (PC/NPC) executes command. The argument is treated just as
if a normal PC entered a command at the command prompt in the
game. It is not directly possible to detect whether the command
was a success or fail. For example, you might force a PC to
"get key". If there is no 'key' available, the PC will get
notified the normal way. Plenty of examples are given above.
wait ( i : integer , dilexp )
i : Message class to accept, see SFB_* in values.h and/or vme.h
dilexp : Expression that has to be TRUE or not null to accept message.
result: Waits for a command, matching the flagset, and satisfies the
expression. When using the 'wait()' command, the first argument
is an integer, that tells what classes of messages to wait for.
Each message class is represented by a bit named as described in
the chapter on messages.
Example:
wait (SFB_TICK|SFB_MSG, TRUE)
/* Will accept a message, either from another DIL program or a
timer message. As the second argument is always TRUE, any
such message will reactivate the DIL program.
*/
Example:
wait (SFB_CMD, command("transmutate"))
/* waits for an command entered named 'transmutate'.
Activates the DIL program, that then can block the command, or
let it pass (and then let the game produce the normal error
message for unknown commands).
*/
</A>
Function: integer savestr( filename : string , buff : string , wa :string);
filenameFILE_SAVED, FILE_NOT_SAVED, FILE_NOT_CREATED, or FILE_ILEGAL_OPP
Savestr is used to save strings to disk to be loaded later by the 'load' function.
The 'savestr' and 'Loadstr' is perfect for operations such as
on-line edited newspaper, a lottery where the tickets are sold to players,
creating smarter NPC's that can remember through reboots who they are hunting,
Dil based teachers, message boards, mail system, news command., zone or
room based help, competition boards, and much much more.
Note:The append/write argument must be in lower case and can only be a
'w' or a 'a' surrounded by '"'. If the argument is a 'w' it will over write
any string file by that name. If the argument is 'a' it will append to the
file by that name.
Disk access is always slow.
If you use loadstr on a continuous basis always
attempt to keep file sizes to a minimum for quick loading. Otherwise you
might cause serious delays on the server.
Example:
dilbegin news_save (arg:string /*for saving*/); var ret:integer;/*to hold the return value if saved or not*/ code { ret:= savestr("news.txt",arg,"w"); if (!ret) { log ("File not wrote"); quit; }
sendtext("New news file wrote.[&]n",self); quit;/*dil save routine done destroy self.*/ } dilend

secure ( u : unitptr , label )
u : Unit to secure.
label : Label to jump to, on removal.
result: Secures a unitptr, so that the program will go to 'label'
if unit leaves local environment. If this happens, during
a call to another function/procedure, it will continue
at that label when the function/procedure returns.
If you perform some kind of call to a template, the removing
of a unit from the local environment will not have affect.
until the return from that function, as the program execution
will continue at the designated label after a call. Should
several secured units leave local environment, the last such
event will determine the point of execution upon return.

Function: stringlist unitdir( match : string ) ;

Example DIL:
dilbegin aware reload_corpse(); var corpselist:stringlist; u:unitptr; ln:integer; i:integer; x:extraptr; code { corpselist:=unitdir("corpse*"); ln:=length(corpselist); i:=0; while (i<ln) { u:=restore(corpselist.[i],null); x:=CORPSE_EXTRA in u.extra; if (u!=null) if (x!=null) link (u,findroom(x.descr)); else link (u,findroom("temple@udgaard")); i:=i+1; }quit; } dilend
The previous DIL example is the DIL used in restoring corpses to the game in case of a crash. For more information you can see how the death DIL'S work by reading through the file death.zon in the vme2.0/zone. directory.
unsecure ( u : unitptr ) u : Secured unit. result: Drop secure on a given unit.
block
result: Blocks any command issued by a player or mobile. Blocking a
command prevents the command from being parsed by the
interpreter. This is ideal if you need to make a routine
which intercepts a command, reacts on it in a special way,
and does not need the standard way of reacting.
priority
result: Set until nopriority command. When set, no special routines
"below" the current DIL program will be executed. This is used
to make other special routines idle. See haon-dor.zon for an
example.
nopriority result: Cancels the priority procedure.
addequip ( u : unitptr , i : integer )
u : Unit to equip.
i : Where to equip unit.
result: Equips unit, presumed to be in inventory PC/NPC at
given position. See WEAR_* in values.h and/or vme.h
unequip ( u : unitptr ) u : Unit to unequip. result: Unequipes unit presumed to be in equipment of PC/NPC.

if (not isplayer(arg)) { sendtext (arg+" is not a character.&n",self); quit; } dilcopy ("god_delete@clans("+arg+")",self);
sendtext (arg+" has been deleted.&n",self); quit; } dilend
dilcopy( s : string, u : unitptr )
s : Name template to attach to unit.
u : Unit to attach a dil program to.
result: Attaches a DIL program to a unit 'u', which uses a template
named by 's'.
sendtext( s : string, u : unitptr )
s : text to send
u : Unit to send the text to
result: Sends the string 's' to 'u'. Useful only for nanny stuff,
because no new line appended.
change_speed( u : unitptr, i : integer ) u : the unit on which you wish to alter the current combat speed. i : the amount to add to the speed.
Beware, this is not the 'speed' as in the speed field, rather this is the speed which is calculated during combat. It is used for spells like 'stun' which effectively puts the character out of combat for one round. Such a spell would be implemented like:
change_speed(u, 12)
and would only cause any effect if 'u' was fighting already (if not, use setfighting).
integer transfermoney( f : unitptr, t : unitptr, amount : integer) f : The char the money is taken from t : The char the money is given to amount : How much money. Returns: TRUE is money was transferred, FALSE if could not afford.
If 'f' is null and 't' isn't, then money is created and given to 't'. If 'f' isn't null but 't' is, then money is removed from 'f'.
set_fighting( u : unitptr, t : unitptr ) u : the unit on which attacks. t : the unit being attacked.
This is used to set two characters fighting. If the attacker is fighting already, the target will simply be inserted into the opponent list and perhaps killed a little later.
setweight( u : unitptr, i : integer ) u : the unit on which you wish to alter the weight. i : the new weight
This is needed on for example drink-containers. I.e. if you wish to remove or add some liquid, you must also adjust the weight of the container, or you will mess up things.
setbright( u : unitptr, i : integer ) u : the unit on which you want to change the brightness. i : the new brightness
When you want to increase / decrease the amount of light shed by a unit, use this function. Units with "bright" light up rooms so that people can see.
log( s : string ) s : Text to put in the log. result: Puts text in the log for debugging purposes.
send ( s : string )
s : Message to send.
result: Send a message to all DIL programs in current local environment,
matching the message class SFB_MSG. The message is not received
by those DIL programs in the local environment that is not set up
to wait for that message class.
sendto ( s : string , u : unitptr )
s : Message to send.
u : Unit to send it to.
result: The message is passed to all DIL programs in unit, matching the
message class SFB_MSG. The message is not
received by those DIL programs in the local environment that is
not set up to wait for that message class.
sendtoall( m : string, s : string ) m : Message to send. s : Name idx to send message to. result: Send a message to all units matching a given database name.
Example:
sendtoall ( "some message", "rabbit@haon-dor");
The message "some message" is sent to all units in the world matching the data base name "rabbit@haon-dor". Like 'send()' and 'sendto()', the message received matches the SFB_MSG message class.
sendtoalldil( m : string, s : string ) m : Message to send. s : Name idx to a DIL program to send message to. result: Send a message to all DIL programs matching a given database name.
Example:
sendtoalldil ( "some message", "intercomm@cemetery");
The message "some message" is sent to all DIL program in the world matching the data base name "intercomm@cemetery". Like 'send()' and 'sendto()', the message received matches the SFB_MSG message class.
cast_spell( i : integer, caster : unitptr, medium : unitptr, target : unitptr )
WILL EVENTUALLY BE OBSOLETE AND REPLACED BY THE CAST_SPELL BELOW.
i : Spell index to cast. See SPL_* in values.h and/or vme.h. caster : The caster of the spell. medium : The medium, with which the spell is cast, might be caster. target : The target of the spell.
Use this to cast spells without performing all the usual mana stuff, etc. Very useful with for example rings / items possessing magical abilities.
integer cast_spell( i : integer, caster : unitptr, medium : unitptr, target : unitptr, effect : string )
i : Spell index to cast. See SPL_* in values.h and/or vme.h.
caster : The caster of the spell.
medium : The medium, with which the spell is cast, might be caster.
target : The target of the spell.
effect : A symbolic DIL program which takes no arguments. This will
cause all effects to be suppressed and leave this to the program
specified. A string of "" will cause the ordinary messages to
appear.
returns: The result of the spell.
Use this to cast spells without performing all the usual mana stuff, etc. Very useful with for example rings / items possessing magical abilities. Please note that in the two programs below the variable 'hm' represents the number of hitpoints that will be deducted from the target.
Example:
%dil
dilbegin myeffect(medi : unitptr, targ : unitptr, hm : integer);
code
{
act("The caster is $1N medium is $2N and target is $3N",
A_ALWAYS, self, medi, targ, TO_ALL);

exec("say Result of spell was "+itoa(n), self);
}
dilend
integer attack_spell( n : integer, caster : unitptr, medium : unitptr,
target : unitptr, bonus : integer)
Returns : The amount of damage given.
n : The spell index of the offensive spell (SPL_XXX)
caster : The caster of the spell.
medium : The medium, with which the spell is cast, might be caster.
target : The target of the spell.
bonus : Possible (+) advantage or (-) penalty.

addstring (sl,s); return (sl); } dilend
integer interrupt( flags : integer, dilexp, label )
Set up interrupt matching message classes matching "flags", for example "SFB_COM" or "SFB_COM | SFB_MSG".
When the program is activated on either of the specified conditions the 'dilexp' is evaluated. If true, then execution continues at 'label', otherwise the next interrupt is checked (if any).
Interrupts are saved (restored), when 'recall' is set. Returns an integer which is used for clear() to clear an interrupt.
Example:
The following program shows, that the owner (self) of the program keeps snoring while sleeping. The on_activation ensures that the program is only activated when the owner is sleeping. However, since the interrupt precede the on_activation, these may still be intercepted before the on_activation. The on_activation is just another type of interrupt that reacts on all flags (without actually setting them so that the program is activated).
When the program receives the message "relief" the snoring stops briefly. As used, "relief" may only be set once.
When the program receives the message "cured", the snoring stops completely (i.e. the program quits itself).
dilbegin
var i : integer;
code
{
/* Notice that the sequence in which the interrupts (and the on_activation)
are executed, is quite important: You can be cured at *any* time. The
program will skip if you are not sleeping. If you are sleeping you can
be relieved. */
interrupt(SFB_MSG, argument == "cured", the_end);
on_activation(self.position != POSITION_SLEEPING, skip);
i1 := interrupt(SFB_MSG, argument == "relief", relief);
:loop:
exec("snore", self);
pause;
goto loop;
:relief: /* Suppose you can only be relieved once, then we must clear interrupt */ clear(i1); pause; pause; goto loop;
:the_end: /* Person is cured... */ quit; } dilend
clear( i : integer )
Clears the interrupt number "i". If i is invalid, this will either clear an wrong interrupt or do nothing.
integer on_activation ( dilexp , label ) dilexp : A boolean DIL expression. label : Label to jump to - OR the reserved keyword SKIP. returns : The index to the interrupt handing the on_activation.
result: Sets up an interrupt that is executed before every activation
of the DIL program. This is for example useful to catch
situations where your NPC has fallen asleep or is injured.
If 'dilexp' evaluates to TRUE then the program jumps to 'label'.
If 'label' is 'skip' then the program is simply not activated.
When the on_activation evaluates to true, and jumps to a label
other than skip, the condition is automatically cleared. If the
dilexp evaluates to false, or if the label is skip, the activation
