AI Scripting and Mapping

This page describes all AI scripting and mapping related additions and changes introduced by Phobos.

Bugfixes and Miscellanous

  • Script action Move to cell now obeys YR cell calculation now. Using 1000 * Y + X as its cell value. (was 128 * Y + X as it's a RA1 leftover)
  • The game now can reads waypoints ranges in [0, 2147483647]. (was [0,701])
  • Map trigger action 125 Build At... can now play buildup anim optionally (needs following changes to fadata.ini.
  • Both Global Variables (VariableNames in rulesmd.ini) and Local Variables (VariableNames in map) are now unlimited.
  • Script action Deploy now has vehicles with DeploysInto searching for free space to deploy at if failing to do so at initial location, instead of simply getting stuck.

Script Actions

10000-10999 Ingame Actions

10000-10049 Attack Actions

  • These actions instruct the TeamType to use the TaskForce to approach and attack the target specified by the second parameter which is an index of a generic pre-defined group. Look at the tables below for the possible actions (first parameter value) and arguments (the second parameter value).
  • For threat-based attack actions TargetSpecialThreatCoefficientDefault and EnemyHouseThreatBonus tags from rulesmd.ini are accounted.
  • All aircraft that attack other air units will end the script. This behavior is intentional because without it aircraft had some bugs that weren't fixable at the time of developing the feature.
  • AITargetTypes actions instruct the TeamType to use the TaskForce to approach and attack the target specified by the second parameter which is an index of a modder-defined group from AITargetTypess. Look at the tables below for the possible actions (first parameter value) and arguments (the second parameter value).

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=i,n             ; For i values check the next table
Action Argument Repeats Target Priority Description
10000 Target Type# Yes Closer

  • The second parameter with a 0-based index for the AITargetTypes section specifies the list of possible VehicleTypes, AircraftTypes, InfantryTypes and BuildingTypes that can be evaluated.
  • The AITargetTypes index# values are obtained in the new AITargetTypes section that must be declared in rulesmd.ini:

In rulesmd.ini:

[AITargetTypes]  ; List of TechnoType lists
0=SOMETECHNOTYPE,SOMEOTHERTECHNOTYPE,SAMPLETECHNOTYPE
1=ANOTHERTECHNOTYPE,YETANOTHERTECHNOTYPE
; ...

10050-10099 Move Team to Techno Location actions

  • These actions instructs the TeamType to use the TaskForce to approach the target specified by the second parameter. Look at the tables below for the possible actions (first parameter value).

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=i,n             ; For i values check the next table
Action Argument Target Owner Target Priority Description
10050 Target Type# Enemy Closer, higher threat
10051 [AITargetType] index# Enemy Closer, higher threat
10052 [AITargetType] index# Enemy Closer Picks 1 random target from the selected list
10053 Target Type# Friendly Closer
10054 [AITargetType] index# Friendly Closer
10055 [AITargetType] index# Friendly Closer Picks 1 random target from the selected list

10058 [AITargetType] index# Enemy Farther Picks 1 random target from the selected list
10059 Target Type# Friendly Farther
10060 [AITargetType] index# Friendly Farther
10061 [AITargetType] index# Friendly Farther Picks 1 random target from the selected list

10000-10049 General Purpose

10100 Timed Area Guard
  • Puts the TaskForce into Area Guard mode for the given units of time. Unlike the original timed Guard script action (5,n) that just stays in place doing a basic guard operation this action has a more active role attacking nearby invaders or defending units that needs protection.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=10100,n            ; integer, time in ingame seconds
10101 Wait Until Ammo is Full
  • If the TaskForce contains unit(s) that use ammo then the the script will not continue until all these units have fully refilled the ammo.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=10101,0
10102 Regroup Temporarily Around the Team Leader
  • Puts the TaskForce into Area Guard mode for the given amount of time around the Team Leader (this unit remains almost immobile until the action ends). The default radius around the leader is [General] > CloseEnough and the units will not leave that area.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=10102,n
10103 Load onto Transports
  • If the TaskForce contains unit(s) that can be carried by the transports of the same TaskForce then this action will make the units enter the transports. In single player missions the next action must be "Wait until fully loaded" (43,0) or the script will not continue.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=10103,0

12000-12999 Suplementary/Setup Pre-actions

12000 Wait if No Target Found

  • When executed before a new Attack ScriptType actions like Generic Target Type Attack actions and AITargetTypes Attack actions the TeamType will remember that must wait 1 second if no target was selected. The second parameter is a positive value that specifies how much retries the Attack will do when no target was found before new Attack ScriptType Action is discarded & the script execution jumps to the next line. The value 0 means infinite retries.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=12000,n            ; integer n=0

12001 Modify Target Distance

  • By default Moving Team to techno location actions ends when the Team Leader reaches a distance declared in rulesmd.ini called CloseEnough. When this action is executed before the actions Moving Team to techno location overwrites CloseEnough value. This action works only the first time and CloseEnough will be used again the next Movement action.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=12001,n

12002 Set Move Action End Mode

  • Sets how the Movement actions ends and jumps to the next line. This action works only the first time and CloseEnough will be used again the next Movement action.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=12002,n
  • The possible argument values are:
Argument Action ends when...
0 Team Leader reaches the minimum distance
1 One unit reaches the minimum distance
2 All team members reached the minimum distance

14000-14999 Utility Actions

14000 Team's Trigger Weight Reward

  • When executed before a new Attack ScriptType actions like Generic Target Type Attack actions and AITargetTypes Attack actions the TeamType will remember that must be rewarded increasing the current weight of the AI Trigger when the TeamType Target was killed by any of the Team members. The current weight will never surprass the minimum weight and maximum weight limits of the AI Trigger. The second parameter is a positive value.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=14000,n         ; integer n=0

14001 Increase AI Trigger Current Weight

  • When executed this increases the current weight of the AI Trigger. The current weight will never surprass the minimum weight and maximum weight limits of the AI Trigger. Take note that all TeamTypes of the same AI Trigger will update the AI Trigger Current Weight sooner or later. The second parameter is a positive value. Take note that the original game only uses the first of the two Teams for calculating the AI Trigger Current weight at the end of the Trigger life, this action ignores if the Team is the first or the second of the AI Trigger and the Current weight is calculated when is executed the action.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=14001,n

14002 Decrease AI Trigger Current Weight

  • When executed this decreases the current weight of the AI Trigger. Details same as above.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=14002,n

14003 Unregister Team Success

  • Is just the opposite effect of the script action 49,0. Like if the Team failed.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=14003,0

16000-16999 Flow Control

16000 Start a Timed Jump to the Same Line

  • When the timer ends the current script action ends and start again the same script action. The timer jump repeats again (infinite loop) until is stopped with action 16002 or the team is destroyed.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=16000,n           ; integer n=0, in ingame seconds

16001 Start a Timed Jump to the Next Line

  • When the timer ends the current script action ends and start the next one in the script type list.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=16001,n           ; integer n=0, in ingame seconds

16002 Stop the Timed Jumps

  • If the Timed Jumps were activated this action stop the process.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=16002,0

16003 Randomly Skip Next Action

  • When executed this action picks a random value between 1 and 100. If the value is equal or below the second parameter then the next action will be skipped. If the second parameter is 0 means that the next action will never be skipped and 100 means thay always will be skipped.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=16003,n           ; where 0 > n <= 100

16004 Pick a Random Script

  • When executed this action picks a random Script Type and replaces the current script by the new picked one. The second parameter is a 0-based index from the new section AIScriptsList explained below.

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=16004,n

The second parameter is a 0-based index for the AIScriptsList section that specifies the list of possible ScriptTypes that can be evaluated. The new AIScriptsList section must be declared in rulesmd.ini for making this script work:

In rulesmd.ini:

[AIScriptsList]  ; List of ScriptType lists
0=SOMESCRIPTTYPE,SOMEOTHERSCRIPTTYPE,SAMPLESCRIPTTYPE
1=ANOTHERSCRIPTTYPE,YETANOTHERSCRIPTTYPE
; ...

18000-18999 Variable Manipulation

18000-18023 Edit Variable

  • Operate a variable's value
  • The variable's value type is int16 instead of int32 in trigger actions for some reason, which means it ranges from -2^15 to 2^15-1.
  • Any numbers exceeding this limit will lead to unexpected results!

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=i,n             ; where 18000 <= i <= 18023, n is made up of two parts, the low 16 bits is being used to store the variable index, the high 16 bits is being used for storing the param value.

18024 - 18047 Edit Variable using Local Variable

  • Operate a variable's value using a local variable's value
  • Similar to 18000-18023, but the number to operate the value is being read from a local variable

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=i,n             ; where 18024 <= i <= 18047, n is made up of two parts, the low 16 bits is being used to store the variable index, the high 16 bits is being used for storing the local variable index.

18000 - 18071 Edit Variable using Global Variable

  • Operate a variable's value using a global variable's value
  • Similar to 18000-18023, but the number to operate the value is being read from a global variable

In aimd.ini:

[SOMESCRIPTTYPE]  ; ScriptType
x=i,n             ; where 18048 <= i <= 18071, n is made up of two parts, the low 16 bits is being used to store the variable index, the high 16 bits is being used for storing the global variable index.
