UBehaviorTreeComponent::IsRunning

function AIModule Since 4.0

#include "BehaviorTree/BehaviorTreeComponent.h"

Access: public Specifiers: virtualconstoverride

Description

Returns true if the behavior tree logic is currently active and processing execution requests. False before StartTree is called or after StopTree completes.

Caveats & Gotchas

• Still returns true while the tree is paused — use IsPaused() alongside it to distinguish a genuinely halted tree from one that's just suspended.
• Overrides UBrainComponent::IsRunning, so code written against a generic BrainComponent pointer gets the same answer without needing a UBehaviorTreeComponent cast.

Signature

virtual bool IsRunning() const override;

Return Type

bool

Example

Check tree state via the base BrainComponent pointer C++

if (AIController->GetBrainComponent() && AIController->GetBrainComponent()->IsRunning())
{
	// Behavior tree logic is active
}
