Bounding rect? you mean like something that surrounds an object and tells if the two bounding rects touched? That's what I thought he meant by pixel perfect detection. Oops. ^_^;;
No, "pixel perfect" usually means taking the actual shape of the object into account, i.e. comparing their bitmaps. This is obviously a lot more expensive than just comparing the bounding rects. Rest assured that Python has no trouble doing integer arithmetic accurately, and will tell you for certain whether the bounding rects intersect or not. :-) (If you were using floats for your rect coordinates, you might have some accuracy limitations, but that's a general feature of float arithmetic, and nothing to do with Python.) -- Greg Ewing, Computer Science Dept, +--------------------------------------+ University of Canterbury, | Carpe post meridiem! | Christchurch, New Zealand | (I'm not a morning person.) | [EMAIL PROTECTED] +--------------------------------------+
