Cannot use my objects method when accessing from Stage LibGDX

Question

I have a class Card with the method setOwner. I have set up my touch input to use a hitActor to identify touches by getting the Actor's name like so :

public boolean touchDown(int screenX, int screenY, int pointer, int button) {
   Vector2 hitCoord = stage.screenToStageCoordinates(new Vector2((float) screenX, (float) screenY));
   Actor hitActor = stage.hit(hitCoord.x, hitCoord.y, false);
    if (hitActor != null) {
            stage.getRoot().findActor(hitActor.getName()).setOwner();// here it doesnt identify the setOwner() method;
    }
    return false;
}

The problem is that it doesn't identify the method setOwner(). My Card actors are in a ListArray deck so I type casted them like so :

  for (Card c : deck) {
        c = (Card) stage.getRoot().findActor(c.getName() + c.getSuit());
    }

But still it doesn't identify the methods declared in the Card class. My goal is to call the methodsetOwner on the Actor that got touched.

Answer 1

I am assuming your Card class extends Actor, but since setOwner only exists on Card you can't call it without casting the Actor to a Card first.

Also, since the hit test returns an Actor you shouldn't have to ask the Stage for it by name using the findActor method.

Consider changing your code to something like this;

if (hitActor != null && hitActor instanceof Card) {
    ((Card)hitActor).setOwner ();
}
