CfgBrains Config Reference – Arma 3

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 Components
		{
		};
	};
	class DefaultAnimalBrain
	{
