i am working on a unit selection freature, and have
URTSSelectable : public UActorComponent
{
GENERATED_BODY()
public:
UFUNCTION(BlueprintCallable, BlueprintImplementableEvent, Category = “RTS Selection”)
void OnSelected();

UFUNCTION(BlueprintCallable, BlueprintImplementableEvent, Category = "RTS Selection")
void OnDeselected();

};

but when i got an actor BP have this AC attached, actor can’t implement the AC methods OnSelected, but i subclass use Selectable subclass URTSSelectable , it will show in the Selectable event graph. so what’s wrong? just because actor is not subclass of AC?
how can i override functions in actor? i hate AC → getOwner → cast to → call function, cast to is so bad.

You can’t override the functions from one class inside another class.

I would say it depends on the use case as to whether or not this is bad design. Some times you can’t get away from it. For instance, I believe the CharacterMovementComponent is tightly coupled to the ACharacter pawn which means you can’t use the component on other actors.

That said, I tend to prefer to decouple those things which is what I believe you’re after. One way I accomplish this is to use an interface. That way the actor component doesn’t have to know what kind of actor it’s attached to. I simply call the interface function and if the owning actor implements it then great, otherwise nothing happens.
