I am trying to make a boss with a healthbar and it works but I want to make it so that the healthbar stays above the boss, even if the boss turns. Does anyone know how to do that?

have you tried using setLocation()?

yes but I don't know how to access the boss's location from the healthbar

I think in the healthbar class you need to add Boss boss = new Boss() (or whatever the boss is called) and I think the setLocation is getWorld().setLocation but I dont really know

That will not work. That will create a second Boss object and will it will not tell you anything about where the one already in the world is at.

You cannot use an Actor class method (setLocation) on a World object (from getWorld). The Boss object should keep a reference to its health bar and it (the boss) should re-position the bar anytime it (the boss) moves.

How would I do that. How do I set the location of the health bar from the boss

Oh. Ok. I guess I'm dumb. What WOULD be the solution, then?

If your health bar had a field: 
private Boss boss;
and if the boss that is in the world was assigned to that field, then you could use something like: 
boss.setLocation(getX(), getY()-25);
Hold on -- editing massively here.

Would that be in the boss class, or in a separate helthbar class?

I said hold on. Now I have to type everything out again -- but correctly.

My third word indicates what class.

If you have to ask that, you better start from the beginning: Trail: Learning the Java language
