I've tried and tried but cannot get part of my screen to scroll without the whole screen scrolling.
I basically have a class which implements screen with two stages in it, one stage I add my tile map rendering actor which has an
ortho camera, the other stage has a hud - simeple image actor. Now, when I update the cameras x position in the first stage,
the tile map moves but so does the hud stage. How can I get a hud just below my tile map? Do I need
to change the view port or something? I'm confused??!?!?
