There are "side-scrollers" written in Python including impressive games like these: http://www.pygame.org/project/406/ http://www.pygame.org/project/381/ I see that you're using the surfarray module, which is probably what you want to do if you're accessing the screen at a pixel level (as opposed to blitting sprites). My experiences with Numeric/numpy and Pygame are limited to recolouring bitmaps, but it's certainly possible to refresh a reasonable size of surface at a decent rate on reasonably fast hardware. One important hint whose relevance I'm not sure about here is that you should attempt to avoid frequent format and bit depth conversions; for sprites and images this usually involves converting them to the same format as the display surface, but I can imagine that there may be implications for surfarrays, too. I hope this gives you some ideas, anyway. Paul -- http://mail.python.org/mailman/listinfo/python-list
