Arma 3: CfgBrains Config Reference

Introduction

CfgBrains allows to tweak some global AI behavior. Exposed and working are countermeasure reaction, suppression reaction and targeting capabilities.

Default exposed setup

class CfgBrains
{
    class DefaultSoldierBrain
    {
        class Components
        {
            class AIBrainAimingErrorComponent
            {
            };
            class AIBrainCountermeasuresComponent
            {
                minReactionTime = 0.1;
                maxReactionTime = 3;
                randomReactionTimePercent = 0.3;
                CMOnTargettedProbability = 0.5;
            };
            class AIBrainSuppressionComponent
            {
            };
            class AIBrainTargetSelectorComponent // seems not implemented in 1.82
            {
            };
        };
    };
    class DefaultCivilianBrain
    {

        {
        };
    };
    class DefaultAnimalBrain
    {
        class Components
