UBTTaskNode::WrappedAbortTask

function AIModule Since 4.0

#include "BehaviorTree/BTTaskNode.h"

Access: public Specifiers: const

Description

Internal wrapper the behavior tree runtime calls instead of AbortTask directly, resolving instanced nodes before aborting. It is what actually runs when a higher-priority branch interrupts this task.

Caveats & Gotchas

• Not intended to be called or overridden directly; override AbortTask instead.
• If AbortTask returns InProgress, the tree waits until FinishLatentAbort is called before continuing evaluation — forgetting that call stalls the whole tree.
• Like WrappedExecuteTask, template (non-instanced) nodes must treat AbortTask as effectively const since it's shared across AI instances.

Signature

EBTNodeResult::Type WrappedAbortTask(UBehaviorTreeComponent& OwnerComp, uint8* NodeMemory) const;

Parameters

Name	Type	Description	Default
OwnerComp	UBehaviorTreeComponent&	The behavior tree component driving execution.	—
NodeMemory	uint8*	Pointer to this node's instance memory block.	—

Return Type

EBTNodeResult::Type

Example

Override the underlying abort instead C++

EBTNodeResult::Type UMyTask::AbortTask(UBehaviorTreeComponent& OwnerComp, uint8* NodeMemory)
{
	// Called via WrappedAbortTask() by the BT runtime
	return EBTNodeResult::Aborted;
}
