I have some questions about scroll-type movement and rotation. First, when you rotate, how do you get it to move in the new "front" direction? And also, I need the player to be able to move any direction, and I need the player to stay in the middle of the screen. Would I move the rest of the world instead of the player, because if I moved the player, wouldn't it just go off the screen? or is there a way for the screen to follow the player?
