UBlackboardComponent::PauseObserverNotifications
#include "BehaviorTree/BlackboardComponent.h"
Access: public
Description
Suspends dispatch of blackboard change notifications; any key changes made while paused are queued rather than immediately broadcast to observers.
Caveats & Gotchas
- • Must be paired with a later call to ResumeObserverNotifications, otherwise queued key changes never notify observers (and behavior tree decorators won't re-evaluate).
- • Useful when performing a batch of SetValue calls where you only want observers to react once, after the whole batch completes.
