Overview

The AI is characterized by a set of sub-skills.

Value of each of the sub-skills is inherited either from skill value (set by skill slider in Insert Unit dialogue (default 0.6) or setSkill command) or directly defined by setSkill command.

This value is interpolated into the corresponding range. This range is defined by a range set in CfgAISkill influenced by the value that comes from Game Options/Difficulty - AI Level (skillAI or precisionAI in player's .Arma3Profile if aiLevelPreset=3 (custom) is used).

CfgAISkill

CfgAISkill is a set of arrays, related to AI Sub-skills, defining the interpolation curve of each of the sub-skill.

Example: In {w, x, y, z} value from (w,y) gets interpolated into (x,z).

Interpolation with vanilla A3 CfgAISkill

spotDistance[] = {0,0.2, 1,0.4}; value in a range 0-1 will change into value in a range 0.2-0.4. setSkill ["spotDistance", 0.5] results in skill "spotDistance" returning 0.3

Notes

More than 2 pairs of defining values can be used (minimum is 2 pairs).

The values are used to interpolate on run-time, so even after setting sub-skill by script command it will be interpolated and bound by this array.

Sub-Skills

AI skill/level/final skill

Sub-skills are a set of parameters ultimately defining the individual AI unit performance in the game.

Name	Description
aimingAccuracy	Affects how well the AI can lead a target Affects how accurately the AI estimate range and calculates bullet drop Affects how well the AI compensates for weapon dispersion Affects how much the AI will know to compensate for recoil (Higher value = more controlled fire) Affects how certain the AI must be about its aim on target before opening fire
aimingShake	Affects how steadily the AI can hold a weapon (Higher value = less weapon sway)
aimingSpeed	Affects how quickly the AI can rotate and stabilize its aim (Higher value = faster, less error)
commanding	Affects how quickly recognized targets are shared with the group (Higher value = faster reporting)
courage	Affects unit's subordinates' morale (Higher value = more courage)
endurance	Disabled in Arma 3
general	Raw "Skill", value is distributed to sub-skills unless defined otherwise. Affects the AI's decision making.
reloadSpeed	Affects the delay between switching or reloading a weapon (Higher value = less delay)Object Modifiers
spotDistance	Affects the AI ability to spot targets within it's visual or audible range (Higher value = more likely to spot) Affects the accuracy of the information (Higher value = more accurate information)
spotTime	Affects how quick the AI react to death, damage or observing an enemy (Higher value = quicker reaction)

Notes

Each sub-skill is used in several calculations. Value of each sub-skill is inherited from the value set by skill slider in Insert Unit dialogue or setSkill command, or more precisely with setSkill alternative syntax. This value is interpolated into ranges defined in CfgAISkill and multiplied by a value of AI Level Skill or Precision set in player's profile (.Arma3Profile file).
