Blackboard Keys on C++

Within your C++ you’d define a property such as:

FBlackboardKeySelector MyBlackboardKey.

Then you end up with:

I.e: ExecuteTask(UBehaviorTreeComponent& OwnerComp,…)
UBlackboardComponent* MyBlackboard = OwnerComp.GetBlackboardComponent();
MyBlackboard->ClearValue(Key.SelectedKeyName);
MyBlackboard->GetValueAsBool(Key.SelectedKeyName);
MyBlackboard->SetValueAsBool(Key.SelectedKeyName, false);

To be 100% accurate, in this particular example it should be:

UBlackboardComponent* MyBlackboard = OwnerComp.GetBlackboardComponent();
MyBlackboard->ClearValue(**MyBlackboardKey**.SelectedKeyName);
MyBlackboard->GetValueAsBool(**MyBlackboardKey**.SelectedKeyName);
MyBlackboard->SetValueAsBool(**MyBlackboardKey**.SelectedKeyName, false);

The variable “Key” appeared out of nowhere and might be misleading.

Also, you should declare the key as **public **and with below property to make it editable in the editor:

UPROPERTY(EditAnywhere)
FBlackboardKeySelector MyBlackboardKey;
