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];

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

Addionally the AI skill is also influenced by the global setting in the difficulty menu.

Sub-Skills

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

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 Arma3

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)

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)

CfgAISkill

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

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

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};
