Return Type
bool Caveats & Gotchas
- • Also calls UseBlackboard() internally if the BT asset has a BlackboardAsset set — you do not need to call both.
- • Calling RunBehaviorTree while a tree is already running will restart from the root.
- • Returns false if the BT component couldn't be created or the asset is invalid.
Example
Start a behavior tree when the controller possesses a pawn C++
void AMyAIController::OnPossess(APawn* InPawn)
{
Super::OnPossess(InPawn);
RunBehaviorTree(PatrolBehaviorTree);
