I've always used backdrop objects for floor graphics in my games, but I was wondering if this is the most efficient way of actually creating floor?
I'm trying to make my stuff with memory efficiency in mind, so I wanted to ask if this the best way of doing it? Would the duplicated floor graphics end up causing the game to slow down?
Also another little thing I was wondering, should power of 2 sizes be used for all of a game's sprites, or does it not matter that much?
