Level Script commands

Every map of KeeperFX, like the original game, has a script file that describes how the game works. KeeperFX has a changed and expanded level script compared to the original game. This document assumes you are writing KeeperFX script, in which case you need to include the LEVEL_VERSION(1) command in your script or KeeperFX will interpret the level as a classic DK map.

KeeperFX can also run maps that use the original Dungeon Keeper script. The commands reference for that can be found here. If you want to convert Dungeon Keeper maps to KeeperFX maps follow this guide.

Finding the level script

When you first save your level, a number of files are created in the Levels directory. For example, for level 200 (the example map), the following files are created:

Map00200.apt
Map00200.clm
Map00200.dat
Map00200.inf
Map00200.lgt
Map00200.lif
Map00200.own
Map00200.slb
Map00200.tng
Map00200.txt
Map00200.wib
Map00200.wlb

For KFX format maps, .lif/.tng/.apt/.lgt files are replaced by .lof/.tngfx/.aptfx/.lgtfx files.

You will notice that there is a .txt file included in the list. This is the script file which you will edit.

If you open it, you will see that it contains many commands which the game uses to create the level. When you have looked at the example script, open the script file of your own level.

Script layout

You can enter commands into the script in any order. The script does not run in the same way as most other programs or HTML scripts. Instead, KeeperFX stores it all in memory. This means that code guarded by IF statements will be executed immediately when their conditions are met. Bear this in mind when you are writing your scripts. When working with conditions that are disabled in the script, note that they are evaluated from 'top level' to 'bottom level'.

IF(PLAYER0,FLAG1 >= 1)
  IF(PLAYER0,MONEY < 10000)
    NEXT_COMMAND_REUSABLE
    ADD_GOLD_TO_PLAYER(PLAYER0,1000)
  ENDIF
  SET_FLAG(PLAYER0,FLAG1,0)
ENDIF

In this above example the player will never get 1000 gold from the script, because FLAG0 will be reset to 0 before the next script level is evaluated. Best practice is to indent conditions, and to remember that the script is evaluated from left to right before it is read from top to bottom. This means that code blocks within nested IF statements are executed separately to and after the preceding block; these "subblocks" execute only after the entirety of the preceding block has been executed, and only if all preceding IF statements linked to it remain true.

IF(PLAYER0,FLAG0 == 1)
    REM Main block
    IF(PLAYER0,FLAG1 == 1)
        REM Subblock 1
        IF(PLAYER0,FLAG2 == 1)
            REM Subblock 2; will not work, because subblock 1 sets condition 1 to false
        ENDIF
        SET_FLAG(PLAYER0,FLAG0,0)
    ENDIF
    REM do something; always executes, even if condition 2 is true
ENDIF

Beyond the functional, it is good to have your script readable and easy to understand. Use the REM function to add comments and information where applicable. Because Timers, Flags, Action Points and Hero Gates cannot be named, it is best practice to document these at or near the top of the script:

REM FLAGS:
REM PLAYER_GOOD,FLAG3       - Stores when the Knight has been added to the level
REM PLAYER0,CAMPAIGN_FLAG1  - Records in how many campaign levels the player found the hidden shrine

REM TIMERS:
REM PLAYER1,TIMER1 	- Started when Blue Keeper is killed, spawns parties from the east
REM PLAYER2,TIMER1 	- Started when Blue Keeper is killed, spawns parties from the west
REM PLAYER_GOOD,TIMER2  - Time between discovering the hidden treasure room and spawning a Knight

REM HERO GATES:
REM 1 - Hidden beyond the gems
REM 2 - Central room of the fortress

REM ACTION POINTS:
REM 1 - North of the red portal
REM 2 - At the entrance of the fortress

To keep the script readable and easy to look at when searching for errors, it is good practice to keep to the following format so others can look at your script without finding it incomprehensible:

- Comments
- Setup Commands
- Modified rules and creature statistics
- Availability
- Hero Parties
- Advanced script blocks
- Scenario
- Victory condition

Some example scripts are provided at the end of this documentation.

Note: There is a limit on how many commands can be used in a same script:

256 CREATE_PARTY
256 ADD_TUNNELLER_PARTY_TO_LEVEL
256 ADD_PARTY_TO_LEVEL
512 IF
2048 script values

You can track how many commands you have in your script by opening the KeeperFX log file and looking for the line "Used script resources:"

Script Parameters and Variables

This section will describe parameters to script commands available to use in Dungeon Keeper.

Players

There are nine players in the game. Each has a number and colour.

Player	Player Command	Colour	Number
Player 1 (single player)	PLAYER0	RED	0
Player 2 (enemy)	PLAYER1	BLUE	1
Player 3 (enemy)	PLAYER2	GREEN	2
Player 4 (enemy)	PLAYER3	YELLOW	3
Hero Dungeon	PLAYER_GOOD	WHITE	4
Neutral	PLAYER_NEUTRAL	no colour/multicoloured	5
Player 6 (enemy)	PLAYER4	PURPLE	6
Player 7 (enemy)	PLAYER5	BLACK	7
Player 8 (enemy)	PLAYER6	ORANGE	8
All Players	ALL_PLAYERS	-	9

Neutral is used for creatures and rooms that have not been claimed by any players, e.g. unclaimed Portals and bonus creatures hidden on the level. The name PLAYER_NEUTRAL is added as a new possible player name, but it works only on some specific commands. Use it for example to place units or modify slabs. As Neutral players have no dungeon, you cannot query information relating to the neutral dungeon structure, for example how many neutral units there are.

The player numbers start at 0 and not 1. The [target player] variables found in the script take the number. Other commands accept the 'player command' or 'colour'.

The main (red) player is player 0 and the one you will almost always use for single player games. KeeperFX allows campaigns played from a different perspective, and multiplayer games will have the client players have non-red colours too.

PLAYER_GOOD is set to 'ROAMING' by default, meaning the heroes or creatures it has do not need a dungeon to function.

Creatures

All the creatures in the Dungeon Keeper have special names which you have to use when referring to them in the script. The following list shows you their proper name and the script name you should use.

Creatures

Heroes

Imp	IMP
Horned Reaper	HORNY

The ANY_CREATURE command may be used on [creature] parameters to target a random creature type.

Note: There is also a FLOATING_SPIRIT creature that is mainly used when your dungeon heart is destroyed (when you click on the Possess icon), or at the very beginning of any levels (when you "enter" into the Dungeon Heart). Floating Spirits can be added into creature pool, but they are useless so you can avoid them.

Note: How you design your level is up to you but when Dungeon Keeper was being developed, they made certain creatures not come through the Portals. Ghosts are created when a creature dies from torture. Skeletons are created when a creature dies in a Prison. Horned Reapers are only available through a sacrifice in the Temple and Vampires only rise from the Graveyard. Tentacles like water and are only bonuses on those levels with water. Bear this in mind when you are scripting your level.

Criterion

There's criteria, to be used on spells like LEVEL_UP_CREATURE, that select a specific creature.

criterion	description
ANYWHERE	Creature anywhere on the level
AT_ACTION_POINT[#]	Unit at specified action point
MOST_EXPERIENCED	Highest level creature
MOST_EXP_WANDERING	Highest level idle creature
MOST_EXP_WORKING	Highest level working creature
MOST_EXP_FIGHTING	Highest level creature in combat
LEAST_EXPERIENCED	Lowest level creature
LEAST_EXP_WANDERING	Lowest level idle creature
LEAST_EXP_WORKING	Lowest level working creature
LEAST_EXP_FIGHTING	Lowest level creature in combat
NEAR_OWN_HEART	Creature close to friendly dungeon heart
NEAR_ENEMY_HEART	Creature close to enemy dungeon heart
ON_ENEMY_GROUND	Creature on enemy tile
ON_FRIENDLY_GROUND	Creature on friendly tile
ON_NEUTRAL_GROUND	Unit on neutral ground, like dirt, water and neutral tiles.

Example:

REM Red units that reach action point 3 turn blue
NEXT_COMMAND_REUSABLE
CHANGE_CREATURE_OWNER(PLAYER0,ANY_CREATURE,AT_ACTION_POINT[3],PLAYER1)

Location

Script commands with the [location] variable, called [where] in the old documentation, accepts the following commands:

COMBAT[player name]	The location of the last battle of the player in the brackets.
CTA[player name]	The location where the Call to Arms power is cast by the player.

COMBAT and CTA can be used without brackets to get the human player, but this must not be used on multiplayer maps.

Variables

Variables are names that have a number associated with them, e.g. the MONEY variable contains the amount of gold that player has. Most variables in Dungeon Keeper are individual to each player and are constantly updated with the correct information.

Game turns

A game turn is a counter that counts how many times Dungeon Keeper has run through it’s main loop. The main loop is a series of commands which tells the game to update and then draw everything on the screen. Each time it runs through these instructions, the game turn counter increases by one and the loop is run again.

When the game runs at default speed, it will do 20 turns per second. So if you want have a one minute delay, you should use 1200 game turns. Players may use frameskip to make it go faster, or use the -fps command line to make it go slower. Also, when the game will lag due to performance issues or multiplayer lag, things could run slower. However, please design for the default speed and avoid maps where players feel the need to frameskip to make the level fun.

Comparisons

The Comparisons are symbols which you can use to compare two values. These will be mainly used by the IF commands.

Command	Description
==	Equal to
!=	Not equal to
<	Less than
>	Greater than
<=	Less than or equal to
>=	Greater than or equal to

Note: If possible, use ‘Less than or equal to’ or ‘Greater than or equal to’ instead of the ‘Equal to’ command because the IF command isn’t checked every game turn. This may cause the game to miss things and therefore cause errors. For example, instead of asking whether the player has 30 creatures, ask if the player has 30 creatures or more.

Action points

Action points are areas of the map that are triggered if a creature steps into it. The Action Point can only be triggered once (unless you use the RESET_ACTION_POINT command) and is player independent so you can only detect which player triggered it.

Each Action Point has a number which you will have to remember. You will use this number in the script.

Hero Gates are special Action Points that act as Portals for Heroes. They do not have trigger areas so you cannot use them as traps, only as entry points for parties or new creatures. Like the Action Points, each Hero Gate has a number and you will need to use this number in the script.

Setup Commands

SET_GENERATE_SPEED

This command tells the game how long to wait before generating a new creature for each player.

SET_GENERATE_SPEED([a])

Where:

[a] - The number of game turns between each creature.

The type of creatures that appear cannot be scripted and will depend on the rooms the player has built. It will apply to all Portals on the map. The value can be changed within IF-statements.

Example:

REM Create a new creature for each player every 500 game turns
SET_GENERATE_SPEED(500)

COMPUTER_PLAYER

If you have placed down an enemy dungeon heart, this command tells Dungeon Keeper that a computer player needs to be assigned. Can be used inside IF-statements to change personalities mid level.

COMPUTER_PLAYER([player],[a])

Where:

[player] - The player’s name, e.g. PLAYER1. See Players section for more information.

[a] - A single number telling the game what attitude the computer player has. See table. Can also be set to 'ROAMING' to make it function like heroes.

Player	Description
0	A general computer player with everything turned on. Builds rooms quickly and is aggressive.
1	Medium aggressive computer player. Builds rooms slowly.
2	Medium defensive computer player.
3	A defensive computer player that only builds rooms 3x3 tiles in size.
4	A defensive computer player that only builds rooms 4x4 tiles in size.
5	An aggressive computer player that only builds rooms 4x4 tiles in size.
6	General aggressive computer player.
7	General defensive computer player.
8	Constructive defensive player that builds 5x5 rooms. Doesn't dig for gold, doesn't move creatures.
9	A computer player which only moves creatures.
10	A medium computer player.
11	Medium aggressive computer player.
12	Rapid Gold Digging Computer with Imp Army.
13	Skirmish Defensive: Can randomly be selected on 1 player maps, turtles
14	Skirmish Peculiar: Can randomly be selected on 1 player maps, will build an onortodox dungeon shape
15	Skirmish Balanced: Can randomly be selected on 1 player maps, plays well rounded
16	Skirmish Rush: Can randomly be selected on 1 player maps, attacks quickly
ROAMING	Roaming creatures that do not need a dungeon to function. PLAYER_GOOD is set to ROAMING by default
OFF	Turns the computer back into a zombie player, without any activity.

Example:

REM Set up and aggressive computer that uses Player 2's dungeon
COMPUTER_PLAYER(PLAYER2,1)

Example 2:

REM On this map the heroes build rooms and can be defeated by killing their heart.
COMPUTER_PLAYER(PLAYER_GOOD,9)
REM And also, there are black roaming creatures on the map that belong to no dungeon and attack everybody.
COMPUTER_PLAYER(PLAYER5,ROAMING)

ALLY_PLAYERS

Sets up an alliance between two players. The difference to original DK is that this command takes 3 parameters - 2 are players, and third one is the status of the alliance. Note that computer players will not break the alliance by themselves, but human player may do so. So this command is mostly for controlling the computer players behavior.

Example:

ALLY_PLAYERS([player],[player],[state])

Where:

[player] - The player’s name, e.g. PLAYER1, which gets the alliance set.

[state] - What happens to the alliance, it can have the following values:

0: Players are enemies, but may change that. Computer Players never will.
1: Players are allied, but may change that. Computer Players never will.
2: Players are enemies, and cannot change this.
3: Players are allied, and cannot change this.

Example:

REM The Blue and Green keepers will not attack each other.
ALLY_PLAYERS(PLAYER1,PLAYER2,1)

Note that if you enable KeeperFX commands with LEVEL_VERSION(1), old ALLY_PLAYERS commands (without the extra parameter) will no longer work. Add a '1' to fix this.

START_MONEY

How much gold each player has at the start of the level.

START_MONEY([player],[gold])

Where:

[player] - The player’s name, e.g. PLAYER1. See Players section for more information.

[gold] - The amount of gold for that player.

Example:

REM Give all players 40000 in gold at the start of the level
START_MONEY(ALL_PLAYERS,40000)

MAX_CREATURES

The maximum number of creatures a player can have. The player can still gain creatures through Scavenging and Torturing but no more will come through the portal until the number of creatures drops below the maximum again.

MAX_CREATURES([player],[a])

Where:

[player] - The player name, e.g. PLAYER1. See Players section for more information.

[a] - The maximum number of creatures. This must be a number below 255.

Example:

REM Player 1 will not gain any more creatures through his Portal once he has 40 creatures in his dungeon
MAX_CREATURES(PLAYER1,40)

ADD_CREATURE_TO_POOL

The creature pool is a set number of creatures that can be attracted by all the players.

Imagine a large group of creatures waiting outside the Dungeon Area (all Portals share this group). A player puts down a room, e.g. a Torture Chamber, and a creature (Dark Mistress) is attracted. The Mistress is taken from this group. If there are no more Mistresses in the group then the player will not be able to gain any more unless he uses other means, e.g. scavenging. This is a first come, first serve system so players will need to hurry if they want to gain the rarest creatures. If a creature becomes angry, it will exit via an Portal and return to the pool. Dead creatures also return to the pool.

This command sets the number of creatures that are placed in this pool. If you leave any creatures off the list then they will not appear in the pool. Use it multiple times (within conditions) to add up.

ADD_CREATURE_TO_POOL([creature],[a])

Where:

[creature] - The creature’s name, e.g. BILE_DEMON. See Creatures section for more information.

[a] - The number of creature’s of that type in the pool.

Example:

ADD_CREATURE_TO_POOL(BILE_DEMON,20)

CREATURE_AVAILABLE

Tells the game whether a creature of specific kind can come through that player's Portal. Parameters of this command have been changed from the original game, and now look like this:

CREATURE_AVAILABLE([player],[creature],[can be attracted],[amount forced])

Where:

[can be attracted] - If set to 1, it is possible to attract the creature, either by rooms or by forced attraction (so it works like 4th parameter in original command).

[amount forced] - Amount of creatures of that kind which can be force-attracted (attracted even if player doesn't have rooms required by that creature). Originally there was no possibility to skip attraction conditions.

DEAD_CREATURES_RETURN_TO_POOL

Normally, when a creature dies, and its body vanishes, it is added to the creature pool again. This command allows you to ensure that all dead creatures are dead forever.

DEAD_CREATURES_RETURN_TO_POOL([a])

Where:

[a] - Logic value to control the creatures returning after death. The default value is 1, allowing dead creatures to come through portal again. Setting it to 0 will prevent dead creatures from returning.

Example:

REM Dead creatures will not return to pool on this map.
DEAD_CREATURES_RETURN_TO_POOL(0)

ROOM_AVAILABLE

This command tells the game that a specific room is available for the player to place down.

ROOM_AVAILABLE([player],[room],[can be available],[is available])

Where:

[player] - The player’s name, e.g. PLAYER1. See Players section for more information. Works with ALL_PLAYERS.

[room] - The room’s name, e.g. TEMPLE. See Room names section for more information.

[can be available] - This value can be set to 0, 1, 2, 3 or 4.

It will not become available at all.
The room becomes available through research.
The room becomes available when researched or when found on the map.
The room may not be researched but becomes available when claimed on the map.
The room becomes available for research after claimed on the map.

[is available] - This value should either be 0 or 1. If it is 1 then the room is available straight away. If it is 0 then the room can not be build until the conditions of 'can be available' are met.

Example:

REM This Treasure Room has been set so that it is available from the start of the level.
ROOM_AVAILABLE(ALL_PLAYERS,TREASURE,1,1)

REM This Torture Chamber has been set do that it needs to be researched before it becomes available.
ROOM_AVAILABLE(ALL_PLAYERS,TORTURE,1,0)

MAGIC_AVAILABLE

This command tells the game that a specific power is available for the player to cast.

MAGIC_AVAILABLE([player],[power],[can be available],[is available])

Where:

[player] - The player’s name, e.g. PLAYER1. See Players section for more information. Works with ALL_PLAYERS.

[power] - The power’s name, e.g. POWER_LIGHTNING. See Power names section for more information.

[can be available] - This value can be set to 0 or 1. If it is 1 then you are telling the game that the power may be researched at some point.

[is available] - This value should either be 0 or 1. If it is 1 then the power is available straight away. If it is 0 then the power cannot become available until it is set to 1 or researched.

Example:

REM This Speed Creature power has been set so that it is available from the start of the level.
MAGIC_AVAILABLE(ALL_PLAYERS,POWER_SPEED,1,1)

REM This Conceal Creature power has been set do that it needs to be researched before it becomes available.
MAGIC_AVAILABLE(ALL_PLAYERS,POWER_CONCEAL,1,0)

DOOR_AVAILABLE

This command tells the game that a specific door is available for the player to construct.

DOOR_AVAILABLE([player],[door],[can be available],[number available])

Where:

[player] - The player’s name, e.g. PLAYER1. See Players section for more information. Works with ALL_PLAYERS.

[door] - The door’s name, e.g. BRACED. See Door names section for more information.

[can be available] - This value can be set to 0 or 1. If it is 1 then you are telling the game that the door can be constructed.

[number available] - The number of doors available to the player at the start of the level or when they become available.

Example:

REM The Wooden Door is now available to the player to manufacture and none have been given to him at the start
DOOR_AVAILABLE(PLAYER1,WOOD,1,0)

TRAP_AVAILABLE

This command tells the game that a specific trap is available for the player to construct.

TRAP_AVAILABLE([player],[trap],[can be available],[number available])

Where:

[player] - The player’s name, e.g. PLAYER1. See Players section for more information. Works with ALL_PLAYERS.

[trap] - The trap’s name, e.g. LAVA. See Trap names section for more information.

[can be available] - This value can be set to 0 or 1. If it is 1 then you are telling the game that the trap may be constructed at some point.

[number available] - The number of traps available to the player at the start of the level or when they become available.

Example:

REM *** The Word of Power Trap is now available to the player to manufacture
REM *** and none have been given to him at the start
TRAP_AVAILABLE(PLAYER1,WORD_OF_POWER,1,0)

Script flow control

LEVEL_VERSION

Lets the game know if the level was designed specially for KeeperFX. To use new script commands, you must start the script with LEVEL_VERSION(1). Without it, the new commands will not work properly, and the game will try to emulate old behavior of commands which were modified.

REM

This can be placed at the start of a line to tell the game to ignore any text after it.

Example:

REM ***** Setup Level Section *****

WIN_GAME

Tells the game that you have won the level. This command must be included in single player games to tell the player he has won. In multiplayer levels, it is not necessary. You should always use them with IF commands to make sure something happens to cause the game to end.

Example:

REM Win the level if Player 1's dungeon is destroyed
IF(PLAYER1,DUNGEON_DESTROYED==1)
  WIN_GAME
ENDIF

LOSE_GAME

Tells the game you have lost the level. This command does not always need to be included as you will automatically lose the level if you Dungeon Heart is destroyed. You should include it if there is a strict goal the player needs to attain.

Example:

REM Lose the level if Player 0's total battles lost is 30
IF(PLAYER0,BATTLES_LOST >= 30)
  LOSE_GAME
ENDIF

IF

This is used to test the differences between two values. This could either be a comparison between a variable and a number, or between two variables. If those two values agree with the comparison, the script will continue. If the two values do not agree with the comparison, the script will find the next ENDIF and continue from there.

IF([player],[variable][comparison][a])
IF([player],[variable][comparison][player],[variable])

Where:

[variable] - The name of a variable, timer, flag (all types), creature, room, trap or door.

Checking variable returns its value at the moment. See Variables section for more information.
Checking creature returns how many creatures of that kind a player owns. It doesn't matter if the player can controls them, or they're in custody.
Checking room returns how many slabs of that room the player owns.
Checking trap or door availability returns amount of deployed traps and doors owned by that player.
Checking TIMERx, FLAGx or CAMPAIGN_FLAGx returns its current value.

[player] - The player’s name, e.g. PLAYER1. If ALL_PLAYERS is used, then the condition has to be met for all of the players in order for the commands inside to be executed.

Example:

IF(PLAYER1,VAMPIRE > PLAYER0,VAMPIRE)
    IF(PLAYER0,VAMPIRE >= 1)
        QUICK_OBJECTIVE(1,"Blue has more vampires than you do. Attack him before scavenging starts")
    ENDIF
ENDIF

ENDIF

This command must be placed at the end of all IF statements. This tells the IF command where to jump to when the comparisons in the statement are not met.

See IF commands for examples.

IF_AVAILABLE

Checks availability of an item, and compares it to a second value. That value may be a number or variable. New option values have been added to this command:

IF_AVAILABLE([player],[variable][comparison][a])
IF_AVAILABLE([player],[variable][comparison][player],[variable])

Where:

[variable] - The name of a creature, room, power, trap or door.

Checking creature availability returns how many creatures of that kind can come from portal to that player. The check includes creature pool, players creature limit and whether attraction criteria are met.
Checking room availability returns whether the room can be built by a player. Cost of the room is not considered.
Checking power availability returns whether the power can be cast by a player. Cost of the power is not considered.
Checking trap or door availability returns amount of traps and doors a player has stored, either in workshop or in off-map storage.
Accepts TOTAL_CREATURES, TOTAL_DOORS and TOTAL_TRAPS

Example:

IF_AVAILABLE(PLAYER0,BOULDER > PLAYER_GOOD,TOTAL_CREATURES)
    QUICK_OBJECTIVE(1,"You have more boulders than there are heroes left. Go make pizza.")
    TRAP_AVAILABLE(PLAYER0,BOULDER,0,0)
ENDIF

IF_CONTROLS

Checks creatures controlled by a player and compares is to a second value. That value may be a number or variable. Units in an enemy prison are excluded here.

IF_CONTROLS([player],[variable][comparison][a])
IF_CONTROLS([player],[variable][comparison][player],[variable])

Where:

[variable] - The name of a creature. Returns how many creatures of given kind the player owns, excluding these under enemy control, like in his prison. Also accepts TOTAL_CREATURES, TOTAL_DIGGERS, EVIL_CREATURES and GOOD_CREATURES.

Example:

IF_CONTROLS(PLAYER0,DRAGON < PLAYER0,DRAGON)
    QUICK_OBJECTIVE(1,"Some of your Dragons are in enemy prison. Rescue them before they get converted.")
ENDIF

IF_SLAB_OWNER

Checks if a specific slab on the map belongs to specified player.

IF_SLAB_OWNER([slab x pos],[slab y pos],[player])

Where:

[slab x pos][slab y pos] - The x and y coordinates of the slab. Range 0-85 on a normal sized map.

[player] - The player’s name, e.g. PLAYER1, to check against.

IF_SLAB_TYPE

Checks if a specific slab is of a specific type.

IF_SLAB_TYPE([slab x pos],[slab y pos],[slab])

Where:

[slab x pos][slab y pos] - The x and y coordinates of the slab. Range 0-85 on a normal sized map.

[slab] - The name of the slab to check for. Take if from fxdata\terrain.cfg.

IF_ALLIED

Checks if a player is allied to another player, or tries to be.

IF_ALLIED([player],[target_player][comparison][a])

Where:

[player] - The player’s name, e.g. PLAYER1, who may or may not have an alliance.

[target_player] - The player name that's subject to alliance.

[a] - The value to compare against. Where '0' is not allied and '1' is.

Note that if the Red player clicks the Ally-button of Blue, comparing PLAYER0 to PLAYER1 already evaluates as true, even when blue has not done the same yet. Comparing PLAYER1 to PLAYER0 would still be false. For multiplayer games, check both sides.

Example:

SET_TIMER(PLAYER0,TIMER1)
ALLY_PLAYERS(PLAYER0,PLAYER1,1)

IF_ALLIED(PLAYER0,PLAYER1 == 0)
    QUICK_OBJECTIVE(1,"Blue will not accept this betrayal, prepare for battle.",PLAYER1)
    REM no going back now, lock as enemies
    ALLY_PLAYERS(PLAYER0,PLAYER1,2)
ENDIF
IF_ALLIED(PLAYER0,PLAYER2 == 1)
    IF_ALLIED(PLAYER0,PLAYER1 == 1)
        QUICK_OBJECTIVE(2,"Blue will not accept your alliance with Green, prepare for battle.",PLAYER1)
        REM lock blue as enemy
        NEXT_COMMAND_REUSABLE
        SET_TIMER(PLAYER0,TIMER1)
        ALLY_PLAYERS(PLAYER0,PLAYER1,2)
    ENDIF
    REM lock green as ally
    ALLY_PLAYERS(PLAYER0,PLAYER2,3)
ENDIF

IF(PLAYER0,ALL_DUNGEONS_DESTROYED == 1)
    REM Set on a timer to not win while switching allies.
    IF(PLAYER0,TIMER1 > 60)
        WIN_GAME
    ENDIF
ENDIF

IF_ACTION_POINT

Detects whether an Action Point has been trigger by one of that players creatures. A player can only trigger each Action point once unless you use the RESET_ACTION_POINT command.

IF_ACTION_POINT([action point],[player])

Where:

[action point] - Action Point number. See Action points section for more information.

[player] - The player’s name, e.g. PLAYER1. See Players section for more information.

Example:

REM If Action Point 2 has been triggered by one of Player 1's creatures then perform the following tasks
IF_ACTION_POINT(2,PLAYER1)

  ..

ENDIF

RESET_ACTION_POINT

Once an Action Point has been triggered, it cannot be triggered again unless it has been reset by this command.

RESET_ACTION_POINT([action point],[player]*)

Where:

[action point] - Action Point number. See Action points section for more information.

[player]* - Optional value, resets the Action Point only for the player name mentioned.

Example:

REM After the following line, the action point 3 can be triggered again
RESET_ACTION_POINT(3)

NEXT_COMMAND_REUSABLE

Once any action command, such as ADD_CREATURE_TO_LEVEL or SET_TIMER, has been triggered once, it cannot be triggered again. This means that you cannot create loops or generators that add heroes to the level each time one of your creatures steps foot in a room. To get around this, the Dungeon Keeper script has a special command called NEXT_COMMAND_REUSABLE. You will need to place this in front of every command in the loop to make it work (it does not need to be placed in front of IF commands)

Example:

REM *** This loop adds a new hero to the level at Hero Gate 3 every 1000 game turns. This is done by
REM *** starting a timer, adding the hero when it reaches 1000 and then resetting it again

SET_TIMER(PLAYER0,TIMER0)

IF(PLAYER0,TIMER0 >= 1000)
  NEXT_COMMAND_REUSABLE
  ADD_CREATURE_TO_LEVEL(PLAYER_GOOD,WITCH,-3,1,6,600)
  NEXT_COMMAND_REUSABLE
  SET_TIMER(PLAYER0,TIMER0)
ENDIF

RUN_AFTER_VICTORY

Lets the game know the script should continue to run after the game is won. Normally everything stops as soon as the a player wins the map, but include RUN_AFTER_VICTORY(1) in the script to have the game continue normally until the player presses the space bar. Useful if you want to give a player the chance to complete an optional objective you want to bring over to a next campaign level with a CAMPAIGN_FLAG or EXPORT_VARIABLE.

Flags and Timers

SET_FLAG

Sets up a flag that is assigned a number.

SET_FLAG([player],[flag],[a])

Where:

REM Spawn troll 3 times.
IF(PLAYER0,FLAG2 <= 3)
    IF(PLAYER_GOOD,TIMER1 >= 100)
        NEXT_COMMAND_REUSABLE
        ADD_CREATURE_TO_LEVEL(PLAYER0,TROLL,PLAYER0,1,1,0)
        NEXT_COMMAND_REUSABLE
        ADD_TO_FLAG(PLAYER0,FLAG2,1)
        NEXT_COMMAND_REUSABLE
        SET_TIMER(PLAYER_GOOD,TIMER1)
    ENDIF
ENDIF
REM If player has a lair the troll spawns two more times.
IF(PLAYER0,LAIR >= 1)
    ADD_TO_FLAG(PLAYER0,FLAG2,-2)
ENDIF

COMPUTE_FLAG

Modifies flag's value based on variables or other flags and values.

[alt] - If set to 1, creature flags will be interpreted as in IF_CONTROLS and rooms/doors/traps as in IF_AVAILABLE. Set it to 0 and it takes the value as IF uses it.

Example:

REM PLAYER0 gets a skeleton for every bile demon he has
COMPUTE_FLAG(PLAYER0,FLAG1,SET,PLAYER0,BILE_DEMON,0)
IF(PLAYER0,FLAG1 > 1)
    NEXT_COMMAND_REUSABLE
    ADD_CREATURE_TO_LEVEL(PLAYER0,SKELETON,PLAYER0,1,1,0)
    NEXT_COMMAND_REUSABLE
    ADD_TO_FLAG(PLAYER0,FLAG1,-1)

HIDE_TIMER

BONUS_LEVEL_TIME

Sets time to be displayed on "bonus timer" - on-screen time field, used mostly for bonus levels. But now this command can be used to show bonus timer in any level, and may show clocktime instead of turns. Setting game turns to 0 will hide the timer.

BONUS_LEVEL_TIME([turns],[clocktime]*)

Where:

[turns] - The amount of game turns the timer will count down from. That's 20 per second.

ADD_BONUS_TIME([turns])

Adding New Creatures and Parties to the Level

ADD_CREATURE_TO_LEVEL

This command will add a number of new creatures to the level at the co-ordinates of a specifies Action Point. You cannot set where the creatures head for so you may need to use a party instead.

ADD_CREATURE_TO_LEVEL([player],[creature],[action point],[a],[experience],[gold])

Where:

[player] - The name of the player, e.g. PLAYER1, that the creatures belong to. See Players section for more information.

[creature] - The creature’s name, e.g. DRAGON. See Creatures section for more information.

[action point] - The number of the Action Point where the creatures will appear. Positive integer value. See Action points section for more information. If you want a creature to appear at a Hero Gate, you will need to enter the Hero Gate’s number here. The number must have a minus sign in front of it to distinguish it from the normal Action Points. For example, if you want the creature to appear at Hero Gate 4, the [action point] number will be -4. If you want a creature to appear at player's Dungeon Heart, you need to enter the player's name instead of the number (see Players section).

[a] - The number of creatures that will appear at the Action Point. This can be any number but remember that you can only have up to 255 creatures on the map at any one time so this number should not be too high.

[experience] - The experience level of the creatures.

[gold] - The amount of gold carried by the creatures.

Example:

REM Add 7 level 4 Hero Wizards who are carrying 400 gold at Action Point 3
ADD_CREATURE_TO_LEVEL(PLAYER_GOOD,WIZARD,3,7,4,400)

ADD_TUNNELLER_TO_LEVEL

This commands adds a number of Tunneller Dwarves to the level. They will immediately start digging towards their target. Tunneller Dwarves are the only creatures that can tunnel towards a target.

ADD_TUNNELLER_TO_LEVEL([player],[action point],[head for],[action point/target player],[experience],[gold])

Where:

[player] - The name of the player, e.g. PLAYER_GOOD, that the creatures belong to. See Players section for more information.

[action point] - The number of the Action Point where the Tunneller will appear. Positive integer value. See Action points section for more information. If you want the Tunneller to appear at a Hero Gate, you will need to enter the Hero Gate’s number here. The number must have a minus sign in front of it to distinguish it from the normal Action Points. For example, if you want the Tunneller to appear at Hero Gate 4, the [action point] number will be -4. If you want the Tunneller to appear at player's Dungeon Heart, you need to enter the player's name instead of the number (see Players section).

[head for] - This command tells the Tunneller what it is tunnelling to. You will specify the exact Action Point or Player number in the next command. There are a number of commands you can use:

Description	Command
An Action Point	ACTION_POINT
A Player’s dungeon	DUNGEON
A Player’s Dungeon Heart	DUNGEON_HEART
The dungeon of the player with the highest score	APPROPIATE_DUNGEON

[action point/target player] - This command will tell the Tunneller which Action Point (if the [head for] command was ACTION_POINT) or Player (if the [head for] command was DUNGEON or DUNGEON_HEART) to go to. If the command was APPROPIATE_DUNGEON then this will just be 0 as the APPROPIATE_DUNGEON command sends the Tunneller to the dungeon of the player with the highest score. If you wish to put player here, you must type player number, like 1, not player name. If you will type PLAYER1, the game won't be able to recognize the number and will treat it as 0.

[experience] - The experience level of the Tunneller.

[gold] - The amount of gold carried by the Tunneller.

Example:

REM Add a level 6 Hero Tunneller at Action Point 7. He will tunnel towards Action Point 5
ADD_TUNNELLER_TO_LEVEL(PLAYER_GOOD,7,ACTION_POINT,5,6,400)

REM Add a level 4 Hero Tunneller at Action Point 3. He will tunnel towards Player 2's Dungeon Heart
ADD_TUNNELLER_TO_LEVEL(PLAYER_GOOD,3,DUNGEON_HEART,2,4,400)

REM *** Add a level 9 Hero Tunneller at Action Point 5. He will tunnel towards
REM *** the dungeon of the player with the highest score
ADD_TUNNELLER_TO_LEVEL(PLAYER_GOOD,5,APPROPIATE_DUNGEON,0,9,400)

CREATE_PARTY

This command tells the game to expect a party with a specific name.

CREATE_PARTY([party name])

Where:

[party name] - The name of the party. You can use any name you want but it must be in capitals.

Example:

CREATE_PARTY(FIRST_STRIKE)

ADD_TO_PARTY

This command adds a unit to a party. The party leader - the unit with the highest level, or most power when equal - is the one which will follow an objective, the others will follow the leader. There is a maximum of 30 party members.

ADD_TO_PARTY([party name],[creature],[experience],[gold],[objective],[countdown])

Where:

[party name] - The name of the party. This must have been declared with the CREATE_PARTY command.

[creature] - The creature’s name, e.g. HORNY. See Creatures section for more information.

[experience] - The creature’s experience level.

[gold] - The amount of gold the creatures are carrying.

[objective] - The target of the creatures and where they will make for when they enter the level. You will not need to specify the target player yet. This will be done when you place the party on the map.

These are the possible objectives:

objective	description
ATTACK_DUNGEON_HEART	Attack the nearest Dungeon Heart.
ATTACK_ENEMIES	Attack any enemies.
ATTACK_ROOMS	Attack the nearest rooms.
DEFEND_HEART	Go to own heart and defend it until destroyed.
DEFEND_LOCATION	Never do any objective.
DEFEND_PARTY	Will not do any objective so will not assume party leadership.
DEFEND_ROOMS	Defend nearest owned room, not counting portals, hearts or bridges.
SABOTAGE_ROOMS	Attacks the nearest rooms. Will avoid combat if it can.
SNIPE_DUNGEON_HEART	Attack the nearest Dungeon Heart, and will totally ignore anything else.
STEAL_GOLD	Steal gold from the Treasure Room (amount depends on GoldHold parameter of the creature). Will avoid combat if it can.
STEAL_SPELLS	Go to Library and steal one spell book. Will avoid combat if it can.

[countdown] - Number of game turns before the leader of the party start moving to the objective. Even if this is set to zero, there usually is a little delay (approx. 200 game turns) before the leader starts moving.

Note: In the original game this command could not be used inside an IF-statement, now it can.

Note 2: Parties used to be limited to 8 members, and while this limit is raised, it is generally a good idea to not go much beyond this amount.

DELETE_FROM_PARTY

Removes a unit from a defined party. Use it before the party is added to the level. When two equal units are in the party, the one that was first added will be deleted.

DELETE_FROM_PARTY([party_name], [creature], [level])

where:

[party_name] - The name as defined with the CREATE_PARTY command

[creature] - Creature model to be searched.

[level] - The experience level of the unit that is to be removed.

ADD_TUNNELLER_PARTY_TO_LEVEL

This adds a specified party of creatures to the level with a Tunneller Dwarf as it’s leader. The Tunneller will immediately dig to it’s target and the other creatures will follow.

ADD_TUNNELLER_PARTY_TO_LEVEL([player],[party name],[action point],[head for],[action point/target player],[experience],[gold])

Where:

[player] - The name of the player, e.g. PLAYER_GOOD, that the creatures belong to. See Players section for more information.

[party name] - The name of the party. This must have been declared with the CREATE_PARTY command.

[action point] - The number of the Action Point where the party will appear. Positive integer value. See Action points section for more information. If you want the party to appear at a Hero Gate, you will need to enter the Hero Gate’s number here. The number must have a minus sign in front of it to distinguish it from the normal Action Points. For example, if you want the party to appear at Hero Gate 4, the [action point] number will be -4. If you want the party to appear at player's Dungeon Heart, you need to enter the player's name instead of the number (see Players section).

[head for] - This command tells the Tunneller what it is tunnelling to. You will specify the exact Action Point or Player number in the next command. There are a number of commands you can use:

Description	Command
An Action Point	ACTION_POINT
A Player’s dungeon	DUNGEON
A Player’s Dungeon Heart	DUNGEON_HEART
The dungeon of the player with the highest score	APPROPIATE_DUNGEON

[action point/target player] - This command will tell the Tunneller which Action Point (if the [head for] command was ACTION_POINT) or Player (if the [head for] command was DUNGEON or DUNGEON_HEART) to go to. If the command was APPROPIATE_DUNGEON then this will just be 0 as the APPROPIATE_DUNGEON command sends the Tunneller to the dungeon of the player with the highest score. If you wish to put player here, you must type player number, like 1, not player name. If you will type PLAYER1, the game won't be able to recognize the number and will treat it as 0.

[experience] - The experience level of the Tunneller.

[gold] - The amount of gold the Tunneller is carrying.

Example:

REM *** Add MY_PARTY to the level at Action Point 4 with a level 5 Tunneller as it's leader.
REM *** The party will head for Action Point 1
ADD_TUNNELLER_PARTY_TO_LEVEL(PLAYER_GOOD,MY_PARTY,4,ACTION_POINT,1,5,600)

REM *** Add MY_PARTY to the level at Action Point 10 with a level 4 Tunneller as it's leader.
REM *** The party will head for the dungeon of Player 1
ADD_TUNNELLER_PARTY_TO_LEVEL(PLAYER_GOOD,MY_PARTY,10,DUNGEON,1,4,600)

ADD_PARTY_TO_LEVEL

Very similar to the ADD_TUNNELLER_PARTY_TO_LEVEL command, this adds a party to the level but does not include a Tunneller Dwarf. This means the party will not be able to tunnel to their target.

ADD_PARTY_TO_LEVEL([player],[name],[action point],[a])

Where:

[player] - The name of the player, e.g. PLAYER1, that the creatures belong to. See Players section for more information.

[name] - The name of the party. This must have been declared with the CREATE_PARTY command.

[action point] - The number of the Action Point where the party will appear. Positive integer value. See Action points section for more information. If you want the party to appear at a Hero Gate, you will need to enter the Hero Gate’s number here. The number must have a minus sign in front of it to distinguish it from the normal Action Points. For example, if you want the party to appear at Hero Gate 4, the [action point] number will be -4. If you want the party to appear at player's Dungeon Heart, you need to enter the player's name instead of the number (see Players section).

[a] - The number of copies of the party to be placed down at the Action Point.

Example:

REM Add 2 copies of MY_PARTY to the level at Action Point 5. They belong to Player 3
ADD_PARTY_TO_LEVEL(PLAYER3,MY_PARTY,5,2)

NEW_CREATURE_TYPE

Adds a new creature type to the creature list, and loads the related config for it. So a creature that is not yet in creatures.cfg.

NEW_CREATURE_TYPE([name])

Where:

[name] - The name of the creature to add. Will load [name].cfg from the (campaign) creatures folder.

Mapmakers can bundle their map with a config and sprite that needs to be placed in the correct folder, but without any need to modify game files.

SET_CREATURE_CONFIGURATION

Allows you to make changes to attribute values set in the unit configuration files. E.g. Imp.cfg.

SET_CREATURE_CONFIGURATION([creature],[variable],[value],[second value]*)

Where:

[creature] - Creature model to be modified.

[attribute] - The name of the creature property you want to change, as found in the [attributes], [job], [attraction], [sound] or [sprites] blocks in the unit configs. E.g. SlapsToKill.

[value] - The new value you want to set it to. It accepts the values as used in the config files.

[second value]* - If there are two values to the attribute, use this value.

Use it to tweak creatures on a per map basis.

Example:

REM On this level, Bile Demons costs lots of gold and would like to sit back.
SET_CREATURE_CONFIGURATION(BILE_DEMON,Pay,200)
SET_CREATURE_CONFIGURATION(BILE_DEMON,AttackPreference,RANGED)

SET_EFFECT_GENERATOR_CONFIGURATION

Allows you to make changes to effect generator values set in effects.toml. Look in that file for the possible properties.

SET_EFFECT_GENERATOR_CONFIGURATION([generator][property][value][second value]*[third value]*)

Where:

[generator] - The name of the effect generator as defined in effects.toml.

[property] - The name of the trap property you want to change, as found in effects.toml. E.g. SpawnHeight.

[value] - The new value you want to set it to. If you want to set the 'EffectModel' property, negative numbers are effect elements, positive effects. It accepts names too.

[second value]* - Some properties have 2 or more values to set. For other properties, do not add this parameter.

[third value]* - Some properties have 3 values to set. For other properties, do not add this parameter.

Use it to effect generators on a per map basis, changed within IF-statements. Example:

REM A 4 second eruption happens in the lava lake where lava effect generators are placed.
IF(PLAYER0,TIMER3 > 400)
  SET_EFFECT_GENERATOR_CONFIGURATION(EFFECTGENERATOR_LAVA,EffectModel,EFFECT_BOULDER_BREAK_WATER)
ENDIF
IF(PLAYER0,TIMER3 > 480)
  SET_EFFECT_GENERATOR_CONFIGURATION(EFFECTGENERATOR_LAVA,EffectModel,EFFECTELEMENT_LAVA_FLAME_STATIONARY)

SET_POWER_CONFIGURATION

Makes changes to keeper powers, as originally set in magic.cfg.

SET_POWER_CONFIGURATION([power],[property],[value 1],[value 2/slot/toggle]*)

Where:

[power] - Power model to be modified.

[property] - The name of the power property you want to change, as found in magic.cfg. E.g. 'Castability'.

[value] - The new value you want to set it to. It accepts the values as used in the config files. For 'Properties' and 'Castability' put the value between "quotation marks" if you want to set multiple values at once.

[value 2/slot/toggle]*

If there are two values to the property, use this value.
For Power and Cost, there are 9 slots to edit. Enter a value between 1~9 here.
For Properties and Castability, leave this empty to set [value] as the only value, set to 0 to remove the value from the list of values, set to 1 to add it to the list of values.

Example:

REM Sight no longer shows the progress of the active power
SET_POWER_CONFIGURATION(POWER_SIGHT,Properties,HAS_PROGRESS,0)

REM IF the player has over 50 creatures he can blow them up with time bomb, no longer just imps.
IF(PLAYER0,TOTAL_CREATURES > 50
  SET_POWER_CONFIGURATION(POWER_TIME_BOMB,Castability,"ALL_GROUND OWNED_CRTRS BOUND_CRTRS NEEDS_DELAY")
ENDIF

REM It makes no sense fully charged disease is so expensive, make cheaper
SET_POWER_CONFIGURATION(POWER_DISEASE,Cost,8600,9)

Example 2:

REM Put time bomb on first power page, cave in not used so moved to second page
SET_POWER_CONFIGURATION(POWER_TIME_BOMB,PanelTabIndex,9) 
SET_POWER_CONFIGURATION(POWER_CAVE_IN,PanelTabIndex,18)

SWAP_CREATURE

Replaces a creature with custom creature. Allows you to replaces for example 'FLY', all preplaced ones and all that will spawn on the level, with a 'SWAMP_RAT', provided 'SWAMP_RAT' was added to 'SwapCreatures' in creature.cfg and a file called swamp_rat.cfg is placed in the creatures folder.

It cannot be used inside IF statements and will do the swap before the level is loaded.

SWAP_CREATURE([new_creature],[creature])

Multiple different new creature types can be added to the creature.cfg file, and any number of existing units can be swapped out, this guarantees there are never more than 32 different kinds on a map, but allows for many more over the course of a campaign. At this point, only sprites (how the creature looks) that are already in the game can be used when making a swap creature config.

Example:

REM Since there are no beetles on the map, swap in a super knight to be used as a landlord
SWAP_CREATURE(LORD,BUG)
SET_CREATURE_PROPERTY(KNIGHT,LORD,0)

REM Spawn the powered up knight as the lord of the land

NEW_ROOM_TYPE([name])

Where:

[name] - The name you will define for the room. Used to reference it from now on.

Use the SET_ROOM_CONFIGURATION script command to then configure everything about the room. It can then be made available to the player like all other rooms. The script command is processed before other ones, and as such cannot be used inside IF-statements.

SET_ROOM_CONFIGURATION

[priority] - Priority of the process. This parameter controls which process to choose if more than one process has met the conditions to be conducted.

[data1],[data2],[data3],[data4] - These parameters can have different meaning for different values of ["process name"].

Example 1: Digging to gold processes

In this case, the function definition is:

SET_COMPUTER_PROCESS([player],["process name"],[priority],[money minimum],[turn scale],[gold dug at once],[max distance])

Where:

["process name"] - Can be one of the following:

DIG TO CLOSE GOLD
DIG TO GOLD
DIG TO GREEDY GOLD
DIG TO GREEDY GOLD2

[money minimum] - Minimal amount of money to use the specific process. If a computer player has less gold than [money minimum], it will not use the process, but will check the more "greedy" one. If minimal amount of money is not reached for any process, computer will use its "fail safe" gold digging process.

[turn scale] - Number of game turns to wait before thinking of digging to next vein. The computer will always wait these turns before creating next process for digging gold. Setting small value (like 10) here will allow computer to dig many veins at once.

[gold dug at once] - Number of the gold tiles selected at one time.

[max distance] - Maximum distance from the gold vein to the nearest of computer player’s rooms. The proper values are from 1 to 84.

Note: If you will use all the gold process commands with very small range, the computer player will still dig for far gold when he'll run completely out of it. This is due to a "fail safe" process which exist after these four. To disable digging for gold, you will have to place a first vein just next to the player, and use very large value of [turn scale], e.g. 144000 will make the computer not to dig for gold in 2 hours after digging the first vein.

Example:

REM *** Dig safely for gold if more than 1250 is in treasury; search for vein in 20 squares,
REM *** wait 30 secs before the next digging
SET_COMPUTER_PROCESS(PLAYER1,"DIG TO CLOSE GOLD",0,1250,600,5,20)

REM Don't dig for gold in two hours after first time digging greedly for gold.
SET_COMPUTER_PROCESS(PLAYER1,"DIG TO GREEDY GOLD", 0,  100,76666,5,50)
SET_COMPUTER_PROCESS(PLAYER1,"DIG TO GREEDY GOLD2",0,    0,76666,5,60)

Example 2: Build a specific room processes

In this case, the function definition is:

SET_COMPUTER_PROCESS([player],["process name"],[priority],[room width],[room height],[room index],[required index])

Where:

["process name"] - Can be one of the following:

BUILD A TREASURE ROOM
BUILD A LAIR ROOM
BUILD A LAIR ROOM 4x4

[room width] - Number of tiles width the room should have. Minimum is 2.

[room height] - Number of tiles height the room should have. Minimum is 2. This value shouldn't differ from room width by more than 1. If it will, then a room with non rectangular shape will result.

[room index] - Index of the room. should always correspond to the room in a ["process name"].

Process names	Room indices	Descriptions
n/a	0	None (can be used as [required index])

BUILD A LAIR ROOM / BUILD A LAIR ROOM 4x4	14	Lair (you can only enlarge the lair, making it smaller usually won't work)

[required index] - Index of the room that should exist when building the new room.

Maximum size of a room is restricted only by amount of tiles which a player can mark for digging. Rooms of size up to 23x23 are usually created properly.

Note: You can't build rooms where width and height differ by more than one. If e.g. you will set width to 4, you can only use height values of 3, 4 or 5.

The important rooms: Treasure Room, Lair, Hatchery, Library and Training Room, should have priority around 0. Other rooms should have priority around -10. This will make sure AI will conduct other processes when neccessery.

Example:

REM Build 4x3 treasure room at start
SET_COMPUTER_PROCESS(PLAYER1,"BUILD A TREASURE ROOM",     0,4,3, 2,0)

REM Build only 2x3 hatchery
SET_COMPUTER_PROCESS(PLAYER1,"BUILD A HATCHERY",      0,2,3,13,0)

REM Build 3x3 scavenger room, only  after the Prison has been built
SET_COMPUTER_PROCESS(PLAYER1,"BUILD A SCAVENGER ROOM",-10,3,3,9,8)

SET_COMPUTER_CHECKS

If no important event is occuring, the computer player searches for things that need to be done using checks. Checks are similar to IF commands which allows computer player to undertake a process under some circumstances determined by values of variables.

SET_COMPUTER_CHECKS([player],["checks name"],[check every],[data1],[data2],[data3],[data4])

Where:

[player] - The computer player’s name, e.g. PLAYER1. See Players section for more information.

["checks name"] - Text name of the check which is being altered. See Computer Player Control Parameters for more information.

[check every] - Number of turns before repeating the test.

[data1],[data2],[data3],[data4] - These parameters can have different meaning for different values of ["checks name"].

SET_COMPUTER_GLOBALS

Allows the player to configure the behavior of an AI for specific criteria.

SET_COMPUTER_GLOBALS([player],[dig_stack_size],[processes_time],[click_rate],[max_room_build_tasks],[turn_begin],[sim_before_dig],[min_drop_delay])

Where:

[player] - The computer player’s name, e.g. PLAYER1. See Players section for more information.

[dig_stack_size] - how much digging a computer starts, as a percentage of the current dungeon area

[processes_time] - game turns between performing processes

[click_rate] - game turns between actions: each room tile placed, each dirt highlighted, each unit dropped

[max_room_build_tasks] - how many rooms can be built at once

[turn_begin] - game turns until AI initializes

[sim_before_dig] - simulate outcome before starting action

[min_drop_delay] - when the click rate is faster, take this as a minimum delay between dropping units

SET_COMPUTER_EVENT

Event is a sudden situation that needs a process to be undertaken. Unlike checks, events are triggered by often complicated logic conditions. Both checks and events are used to test if a process should be started.

SET_COMPUTER_EVENT([player],["event name"],[value3],[param1],[param2],[param3],[param4])

Where:

[player] - The computer player’s name, e.g. PLAYER1.

["event name"] - Text name of the event which is being altered. See fxdata\keepcompp.cfg.

[value3] - Updates the third number listed at Values. (test_interval)

[param#] - Updates the four numbers listed at Params. The first 3 have different meanings for different event types, the 4th one is the gameturn the event has last been used.

Use it to tweak computer player behavior on a per map basis. Example:

REM Blue should not add new rooms when at max capacity beyond 36 tiles
SET_COMPUTER_EVENT(PLAYER1,"EVENT CHECK ROOMS FULL",400,0,0,36,0)

Note that without level_version(1) only Param1 and Param2 can be set.

USE_SPECIAL_TRANSFER_CREATURE([player])

Note that the player could - on purpose or by accident - close the menu without transferring a creature. An updated objective will close the menu. Use the CREATURES_TRANSFERRED variable (see Variables) to be sure a creature is transferred.

SET_BOX_TOOLTIP

Creates a custom tooltip for Custom special boxes.

SET_BOX_TOOLTIP([boxnumber],"[Custom tooltip]")

Where:

[boxnumber] - The ID of the custom box. With a new ADiKtEd or the ADD_OBJECT_TO_LEVEL command you can set a number. Multiple boxes may have the same number, and they will get the same tooltip and functionality.

[custom tooltip] - The text that will displayed when you hover your mouse over the Special box.

Example:

SET_BOX_TOOLTIP(4, "Cast Rebound on your creatures.")

REM Place a Special box with ID 4 on action point 2.

Functions

DRAWFROM

Is not a command itself but may replace a parameter of most other commands. Replaces the old RANDOM command.

DRAWFROM(a,b,c,d,e,f,g,h)

It draws at random one value or number from up to eight parameters. Examples:

REM Human player will have random start gold between 10000 and 15000
START_MONEY(PLAYER0,DRAWFROM(10000,11000,12000,13000,14000,15000))

REM One bug type creature will be added to pool
ADD_CREATURE_TO_POOL(DRAWFROM(FLY,BUG,SPIDER),5)

REM Add one of three predefined Hero parties to Hero gate 6 or 9
ADD_PARTY_TO_LEVEL(PLAYER0,DRAWFROM(thugs,fiends,dudes),DRAWFROM(-6,-9),1)

It is also possible to draw a value from a range of numbers using a tilde(~). Example:

REM Spawn a BUG at a random time at the start or near the end of the level
IF(PLAYER0,TIMER1 >= DRAWFROM(0~12000,72000~108000))
    ADD_CREATURE_TO_LEVEL(PLAYER_GOOD,BUG,-1,1,1,500)
ENDIF

Ranges can be combined with values. The '~' is a separate parameter. Combining two values between a tilde will act as three total parameters.
Example with the maximum eight parameters:

DRAWFROM(1~4,6,8~11,13)

A range cannot be used for hero gates, action points or any non-consecutive values.

Value represented by DRAWFROM is selected at start of a map, and never changes during the gameplay.

Script commands added or edited after the latest release

Note: They will only work on alpha versions!

No Script Commands have been added since the release of KeeperFX 1.2

Deprecated

SET_CREATURE_STRENGTH

Note: Although this command is functional, it is recommended to use SET_CREATURE_CONFIGURATION instead

This command sets the strength of all the creatures of that type on the level. Each creature has a default strength which can be found in the creature.cfg file, e.g. the BILE_DEMON has a strength level of 80.

SET_CREATURE_STRENGTH([creature],[a])

Where:

[creature] - The creature’s name, e.g. HORNY. See Creatures section for more information.

[a] - The new strength of that creature. The strength must be between 0 and 255. Putting higher values will not be taken into account.

Example:

REM Set the demon spawn strength to 190
SET_CREATURE_STRENGTH(DEMON_SPAWN,190)

SET_CREATURE_HEALTH

Note: Although this command is functional, it is recommended to use SET_CREATURE_CONFIGURATION instead

This command sets the health of all the creatures of that type on the level. Each creature has a default full health level which can be found in the creature.cfg file, e.g. the DRAGON has a full health level of 900.

SET_CREATURE_HEALTH([creature],[a])

Where:

[creature] - The creature’s name, e.g. ORC. See Creatures section for more information.

[a] - The new health level of that creature. The health level must be between 0 and 7895. If the value is greater, some creatures may instantly die when reaching certain level of experience.

Example:

REM Set the orc health to 1000
SET_CREATURE_HEALTH(ORC,1000)

SET_CREATURE_ARMOUR

Note: Although this command is functional, it is recommended to use SET_CREATURE_CONFIGURATION instead

This command sets the armour of all the creatures of that type on the level. Each creature has a default armour level which can be found in the creature.cfg file, e.g. the Dark Mistress has a armour level of 50.

SET_CREATURE_ARMOUR([creature],[a])

Where:

[creature] - The creature’s name, e.g. HORNY. See Creatures section for more information.

[a] - The new armour level of that creature. The armour level must be between 0 and 255. Putting higher values will still make a final value smaller than 256.

Example:

REM Set the demon spawn armour to 60
SET_CREATURE_ARMOUR(DEMON_SPAWN,60)

SET_CREATURE_FEAR

Note: Although this command is functional, it is recommended to use SET_CREATURE_CONFIGURATION instead

This command sets the fear of all the creatures of that type on the level. Each creature has a default fear which can be found in the creature.cfg file, e.g. the FLY has a fear level of 30.

SET_CREATURE_FEAR([creature],[a])

Where:

[creature] - The creature’s name, e.g. BUG. See Creatures section for more information.

[a] - The new fear level of that creature. The fear level must be between 0 and 255. Putting higher values will still make a final value smaller than 256.

Example:

REM Set the spider fear to 190
SET_CREATURE_FEAR(SPIDER,190)

SET_CREATURE_FEAR_STRONGER

Note: Although this command is functional, it is recommended to use SET_CREATURE_CONFIGURATION instead

SET_CREATURE_FEAR_WOUNDED

Note: Although this command is functional, it is recommended to use SET_CREATURE_CONFIGURATION instead

SET_CREATURE_FEARSOME_FACTOR

Note: Although this command is functional, it is recommended to use SET_CREATURE_CONFIGURATION instead

RANDOM

The RANDOM() function of original DK has been replaced by DRAWFROM. This command is currently unimplemented - use DRAWFROM instead.

It is meant to be a function used in same way as DRAWFROM, but selecting value each time during gameplay instead of doing it once at start of the level.

SET_CAMPAIGN_FLAG

Use SET_FLAG instead, because campaign_flags can be used like other flags, the only difference is that the value is not forgotten at the end of a level.

ADD_TO_CAMPAIGN_FLAG

Use ADD_TO_FLAG instead, because campaign_flags can be used like other flags, the only difference is that the value is not forgotten at the end of a level.

SET_HATE

Script command to make a computer player hate another one, which should cause him to attack. Non-functional in both the original game and KeeperFX.

USE_SPECIAL_LOCATE_HIDDEN_WORLD

Replaced with LOCATE_HIDDEN_WORLD

USE_SPECIAL_MAKE_SAFE

Replaced with MAKE_SAFE
