UBlackboardComponent::SetValueAsClass
#include "BehaviorTree/BlackboardComponent.h"
Access: public
Specifiers: UFUNCTIONBlueprintCallable
Description
Sets the UClass value stored under the given blackboard key, notifying any registered observers if the value changed.
Caveats & Gotchas
- • Silently does nothing if KeyName doesn't resolve to a valid class-type key on the blackboard's data asset.
- • Setting the same class value again does not re-notify observers — notifications only fire when the stored value actually changes.
- • If the key has a base-class restriction configured on the BlackboardData asset, passing an incompatible class is rejected without an error message in Development builds.
