And of course if you don't subclass Window, there is also the nice
decorators for window events, as you probably already know:
mouse_pos = 0, 0
@window.event
def on_mouse_motion(x, y, dx, dy):
mouse_pos = x, y
Keep in mind that changing the Sprite.position is a somewhat expensive
operation, because the Sprite's vertex list is re-calculated every time you
do. For this reason, it makes more sense to use an intermediate variable
(like mouse_pos above), and update the Sprite's position once every update
of your application.
