aiBurstTerminable
- Class
- ModeClass
- Type
- Boolean
- Description
- AI firemode parameter, when true, AI will terminate burst when target is dead or out of sight
aiDispersionCoefX
- Type
- Float
- Description
- Dispersion multiplier for AI units (axis X - left to right).
aiDispersionCoefY
- Type
- Float
- Description
- Dispersion multiplier for AI units (axis Y - top-down).
aiRateOfFire
- Class
- ModeClass
- Type
- Float
- Description
- Delay between shots at given aiRateOfFireDistance.
aiRateOfFireDistance
- Class
- ModeClass
- Type
- Integer
- Description
- At shorter distance delay (aiRateOfFire) goes linearly to zero.
aiRateOfFireDispersion
- Class
- ModeClass
- Type
- Float
- Description
- Property that affects the randomness of delay between shots. Value sets the maximum of the range in which a random number influencing the delay between shots is generated. 0 means the delay between shots will be the same (with given actual distance). The bigger the value the longer delay can be generated.
// randomized delay after shot
timeToShot = aiRateOfFire + aiRateOfFireDispersion * Random<0,1>
min/mid/maxRange...
- Class
- ArmaModeClass
- Type
- Integer
- Description
- Together with range and rangeProbab values, defines probability to use this weapon for AI units at given distance.
minRange
- Type
- Integer
minRangeProbab
- Type
- Float
midRange
- Type
- Integer
midRangeProbab
- Type
- Float
maxRange
- Type
- Integer
maxRangeProbab
- Type
- Float
showToPlayer
- Class
- ModeClass
- Type
- Boolean
- Description
- Some modes defined for AI usage (e.g. burst modes for full auto weapons) can be hidden from player with this parameter.

CfgMoves
variantsAI[]
- Type
- Array
- Description
- Found in States when there are several variations on the same animation (usually idles) that can be played randomly.
It lists the animations to be randomly cycled. The numbers represent the probability of that animation being played, the higher the number, the more likely the animation will get to play.
The sum of these numbers is always 1.

visibleSize
- Type
- Float
- Description
- Found in States, probably used for calculating how visible a character is for the AI, based on his stance/animation.
visibleSize = 1.00012; //SprintBaseDf when sprinting more visible than..
visibleSize = 0.700121; //AmovPercMstpSrasWrflDnon ..when stopped > visible than..
visibleSize = 0.300122; //AmovPknlMstpSlowWrflDnon ..when kneeling > visible than..
visibleSize = 0.100123; //AmovPpneMstpSrasWrflDnon ..when prone.

AIAvoidStance
Integer: Allows restricting the AI from entering prone with two levels of emphasis
| Value | Description |
|---|---|
| 0 | No change in behavior |
| 1 | Less preference for going prone - avoid prone (unless stealth or suppressed or *) |
| 2 | Almost never going prone - never prone (unless *) |
* means commanded, injured, animated, forced, ...
grassCover
Float: Reduces visibleSize (taken from CfgMovesBasic) of unit for AI visibility movement computations (cannot make fully invisible) - it is NOT about visual drawing
grassCover = 0; // Used by GdtStratisConcrete, there will be no simulated grass cover at a distance
grassCover = 0.05; // Used by GdtStratisGreenGrass, there will be some simulated grass cover at a distance
CfgCloudlets
blockAIVisibility
Sets if particles are in the AI visibility tests (default true) - false for better performance but AI is able to see through particles
blockAIVisibility = true;
