Overview

This page contains all information about Arma 3`s artificial intelligence, short AI.

AI Skill

The AI is characterized by a set of sub-skills. Each sub-skill is influence by one of the following:

• Inherited from the value set via setSkill
  • _unit setSkill 0.8;
• Skill set in Eden Editor
• Exact value set by the setSkill command
  • _unit setSkill ["reloadSpeed", 0.8];
• AI skill is also influenced by the global setting in the difficulty menu.

Each sub-skill is then interpolated with the values set in CfgAISkill.

Sub-Skills

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

Sub-Skill	Effect	Influence
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 Affects how certain the AI must be about its aim on target before opening fire	Higher value means the AI can lead a target better Higher value means the Ai can estimate range and calculate bullet drop more precicely Higher value means the AI can compensate weapon dispersion better Higher value means the AI can control the recoil better Higher value means the AI needs to now less to open up fire
aimingSpeed	Affects how quickly the AI can rotate and stabilize its aim	Higher value means the AI can rotate and stabilize its aim faster
commanding	Affects how quickly recognized targets are shared with the group	Higher value means the AI can report targets faster
courage	Affects unit's subordinates' morale (Higher value = more courage)	Higher value means the AI has got more courage
endurance	Disabled in Arma3	Disabled
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 means the AI can switch or reload weapons faster
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)	Higher value means the AI is better at spotting targets Higher value means the AI will collect information about targets more precisely
spotTime	Affects how quick the AI react to death, damage or observing an enemy	Higher value means the AI will react faster to death, damage or enemies
aimingShake	Affects how steadily the AI can hold a weapon (Higher value = less weapon sway)	Higher value means the AI will be more precise

CfgAISkill

CfgAISkill is a set of arrays, related to AI Sub-skills, defining the interpolation curve of each of the sub-skill. They can be changed by a mod for example.

Example

Interpolation with vanilla A3 CfgAISkill

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

• 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.

Defaults for Arma 3

Table

Sub-Skill	w	x	y	z
aimingAccuracy	0	0	1	1
aimingShake	0	0	1	1
aimingSpeed	0	0.5	1	1
commanding	0	0	1	1
courage	0	0	1	1
endurance	0	0	1	1
general	0	0	1	1
reloadSpeed	0	0	1	1
spotDistance	0	0	1	1
spotTime	0	0	1	1

• w: Original minimal value set by setSkill or Eden Editor
• x: Minimal allowed value, if w is lower. It will be clamped to this value
• y: Original maximal value set by setSkill or Eden Editor
• z: Maximal allowed value, if w is lower. It will be clamped to this value
