One thing that I would do to make it look a little prettier is to prerender the first k frames with the ball having a decreasing alpha, so that the ball looks like it's fading in. While I wouldn't say you've managed to render an infinite number of sprites, this technique might come in handy for some of the bullet hell games people were talking about around here.

Ethan Am I the one that started the whole idea of bullet hell games in this mailing list? heh, well he's definitely right that this little trick would make rendering hundreds of bullets at a time less painful... ...If I could wrap my empty head around it.

T_T My original email had an explanation of the technique but I thought that might be considered spoilers :). It might help you understand if you went into the code. At the very top, there's a line called FRAME_COUNT. Change it to 1 or 2 and see what happens. It's a cute trick, but it relies on certain properties of the sprite motion -- namely that all sprites are identical, and are all following the same trail, but are just on different places on it. I think generally the use of sprites in a game runs counter to these assumptions -- you introduce a sprite class because the sprites aren't identical, and they move differently. But like I said, maybe bullet hell games. Ethan signature.asc Description: OpenPGP digital signature

It would be cool to have, oh say, 2 or 3 of these running at the same time making a pattern. Would that make sense or would it be asking for trouble?
