UBlackboardComponent::IsCompatibleWith
#include "BehaviorTree/BlackboardComponent.h"
Access: public
Specifiers: virtualconst
Description
Returns true if the given blackboard data asset can be used with this component, meaning it matches or derives from the currently assigned asset.
Caveats & Gotchas
- • Compatibility checks walk the asset's parent chain, so a child BlackboardData asset is compatible with a component already using the parent asset.
- • Call this before InitializeBlackboard when swapping assets on an already-initialized component to avoid silently breaking key ID assumptions held by running behavior trees.
