BehaviotTree does not use the given keys

[Ivan3z]

Nop. You must create a new Task Class…

`class UMyTask : public UBTTaskNode`

//Or Service:
`class UMyService : public UBTService`


//Or Decorator
class UMyDecorator : public UBTDecorator

This is the way i use to get a reference to the blackboard variable.

FBlackboardKeySelector AnyVariableInBlackboard;

this is the way to initialize it

@Ivan3z

void UMyClass::InitializeFromAsset(UBehaviorTree& Asset)
{
	Super::InitializeFromAsset(Asset);
 
	UBlackboardData* BBAsset = GetBlackboardAsset();
	if (ensure(BBAsset))
	{
		AnyVariableInBlackboard.ResolveSelectedKey(*BBAsset);
	}
}

and this is the way to get a pointer to the object

@Ivan3z

UObject *Object = BlackboardComponent->GetValueAsObject(AnyAariableInBlackboard.SelectedKeyName);
