UBTTaskNode::WrappedOnTaskFinished
#include "BehaviorTree/BTTaskNode.h"
Access: public
Specifiers: const
Description
Internal wrapper the runtime calls to invoke OnTaskFinished on an instanced node when a task completes. It only actually calls through if bNotifyTaskFinished was set.
Caveats & Gotchas
- • Only fires when bNotifyTaskFinished is true, which is set automatically by calling INIT_TASK_NODE_NOTIFY_FLAGS in the task's constructor if OnTaskFinished is overridden.
- • Not intended to be called or overridden directly; override OnTaskFinished instead.
- • Runs regardless of whether the task succeeded, failed, or was aborted — check TaskResult if the behavior should differ.
Signature
void WrappedOnTaskFinished(UBehaviorTreeComponent& OwnerComp, uint8* NodeMemory, EBTNodeResult::Type TaskResult) const;Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| OwnerComp | UBehaviorTreeComponent& | The behavior tree component driving execution. | — |
| NodeMemory | uint8* | Pointer to this node's instance memory block. | — |
| TaskResult | EBTNodeResult::Type | The result the task finished with. | — |
Return Type
void Example
React to task completion C++
UMyTask::UMyTask(const FObjectInitializer& ObjectInitializer) : Super(ObjectInitializer)
{
INIT_TASK_NODE_NOTIFY_FLAGS();
}
void UMyTask::OnTaskFinished(UBehaviorTreeComponent& OwnerComp, uint8* NodeMemory, EBTNodeResult::Type TaskResult)
{
// Called via WrappedOnTaskFinished() by the BT runtime
