UBlackboardComponent::InitializeComponent
#include "BehaviorTree/BlackboardComponent.h"
Access: public
Specifiers: virtualoverride
Description
Overrides UActorComponent::InitializeComponent to set up the blackboard's default asset (DefaultBlackboardAsset) if one hasn't already been assigned via InitializeBlackboard.
Caveats & Gotchas
- • Only initializes the blackboard from DefaultBlackboardAsset if InitializeBlackboard hasn't already been called explicitly — calling InitializeBlackboard first (e.g. from an AIController) takes precedence.
- • Runs during the standard actor component initialization flow, before BeginPlay, so the blackboard asset may not be ready yet if you read from it in a constructor.
- • You rarely override this directly on UBlackboardComponent itself; it's more common to call InitializeBlackboard explicitly to control asset selection at runtime.

void Example
Rely on default initialization C++
// DefaultBlackboardAsset set in the editor on the component instance
// InitializeComponent() runs automatically and picks it up if InitializeBlackboard wasn't called firstTags
