UBehaviorTreeComponent::UninitializeComponent

function AIModule Since 4.0

#include "BehaviorTree/BehaviorTreeComponent.h"

Access: public Specifiers: virtualoverride

Description

Overrides UActorComponent::UninitializeComponent to tear down the behavior tree instance stack and release runtime node memory before the component is destroyed.

Caveats & Gotchas

• Called by the engine's component lifecycle, not something to invoke directly from game code.
• Runs after EndPlay in the normal actor teardown sequence, so any cleanup relying on world state should happen in StopTree/EndPlay instead.
• If overridden in a derived class, Super::UninitializeComponent() must be called or the tree instance stack and node memory can leak.

Signature

virtual void UninitializeComponent() override;

Return Type

void

Example

Extend cleanup in a derived component C++

void UMyBehaviorTreeComponent::UninitializeComponent()
{
	// Custom cleanup here
	Super::UninitializeComponent();
}
