AI ExecuteTask after ReceiveMoveCompleted

Development Programming & Scripting C++
1

Hey,

I´m currently developing an AI in C++ and came to a problem, where I need some help.

My AI should Move and only after it received the “ReceiveMoveCompleted”-Event from my AIController, it should return a EBTNodeResult::Success. So I´m looking for a way in how to achieve
this. The doc of the BTTaskNode is not really helping me. I´m looking for some sort off “Wait until the event was executed to continue your flow”. Hopefully someone will help me out. I´m currently
inspecting the BTTask_MoveTo BP in the source code, but really can`t figuring out, how they achieved some sort of “waiting” inside the ExecuteTask.


EBTNodeResult::Type UBTTWorkMission::ExecuteTask(UBehaviorTreeComponent& OwnerComp, uint8* NodeMemory)
{
	ownerptr = &OwnerComp;
	AAIController* AIOwner = OwnerComp.GetAIOwner();
	TScriptDelegate<FWeakObjectPtr> MovementComplete;
	const FName name = "FinishedMoving";
	MovementComplete.BindUFunction(this, name);
	AIOwner->ReceiveMoveCompleted.Add(MovementComplete);

	const FName BlackboardKey = "CurrentRoutineGate";
	ARoutineGate* Gate = dynamic_cast<ARoutineGate*>(OwnerComp.GetBlackboardComponent()->GetValueAsObject(BlackboardKey));
	if (Gate)
	{
		CurrentWorkOrder = Gate->GetCurrentWorkOrder();
		UE_LOG(LogTemp, Warning, TEXT("CurrentWorkOrder assigned executed"))
	}
	else {
		UE_LOG(LogTemp, Warning, TEXT("CurrentWorkOrder not assigned"))
	}

	//UE_LOG(LogTemp, Warning, TEXT("CurrentWorkOrder: %d"), CurrentWorkOrder.TimeCost)
	UE_LOG(LogTemp, Warning, TEXT("BTTWorkMission executed"))

	// Executes WorkOrder Logic depending on MissionType
	ExecuteWorkOrderLogic(OwnerComp);

	MoveToWaypoint(OwnerComp);

	// Resets the MissionType to get the next Mission
	ResetMissionType(OwnerComp);
	

	// Succeed, when Mission has finnished

	// Wait with function execution till Recieve MoveCompleted to return EBTNodeResult::Success
	return EBTNodeResult::InProgress; 
}
