Hello. You might be interested in how I implemented it for my game Herder. The source may be downloaded from the page below:
http://www.donationcoder.com/Forums/bb/index.php?topic=6894.msg48198#msg48198 The way it's implemented in this program is actually quite simple: if self.fpx <= -16: self.fpx = self.fpx + 830 if self.fpx >= 815: self.fpx = self.fpx - 830 if self.fpy <= -16: self.fpy = self.fpy + 630 if self.fpy >= 615: self.fpy = self.fpy - 630 Here, fpx and fpy refer to the x and y coordinates of the center of a 32 x 32 sprite. All I'm checking for is if the sprite has gone out of bounds in the "830 x 630" extended screen it's in, and if that happens, just wrap around. I hope this helps :) Chuck Arellano - Game Programming Video Tutorials for Beginners at http://www.scriptedfun.com/ ____________________________________________________________________________________ Cheap talk?
