Help With Paint Order Of Individual Objects

Hi there. I am making a card game where the cards get put into stacks, with the top card facing up. However, occasionally when I play a card, the card goes underneath. Is there anyway to specify the paint order of a specific object of a certain class?

There is no documented way to have specific objects of a class appear above others. However, currently, there is a non-documented trick you can use to make one appear above another. Remove the object from the world and re-add it back at the same location into the world.

I believe you can use setPaintOrder() from World, but it only handles different classes.

Is there any way to do that from the card itself? When I remove the card and re-add it, it throws a null pointer exception because the card no longer exists in the world. Is there anyway to save the reference of the card in order to re-add it later?

Your null pointer was probably due the 'getWorld' not being able to get the World object that the actor was in after it was removed from the world. Get a reference to the world before removing the actor: 
World world = getWorld();
int x = getX(), y = getY();
world.removeObject(this);
world.addObject(this, x, y);
