Is there a more Pythonic way to create the class
"MoveableAnimatedSheetSprite" I am using multiple inheritance but I see
that I am really loading the image twice when I call __init__ for
"AnimatedSheetSprite" and "MoveableSprite". Should I just make a
moveable class and have moveable items inherit it with out inheriting
from "Sprite"?
By the way the code does work as intended right now.
Thank you in advance, if you need more code or what ever just let me know.
