	I can send you some code/notes if you want. I worked on this and collision 
detection quite a bit until I really got it right (the two are somewhat 
correlated), on my own game. In both situations, I saw my code and logic get 
a bit simpler and cleaner after I had the core functionality well implemented 
and had achieved a better understanding of just what I was doing. I simply 
have some generic Python lists for stuff I want to scroll (my Pygame sprite 
groups are used mostly for precise control over the render order of various 
types of sprites). By using lists, it's a cinch to keep shuffling sprites 
around on the virtual world (and even use them in collision detection for 
off-the-screen bullets etc, if I so choose) while still keeping them out of 
sprite groups.
