Hello: I'm rummaging through the oldest parts of my game code to see if, being more experienced now, I can optimize any of them. I came across the code I...
Joe - When I recently started using the colored square libraries, I found there were two copies of a routine called PIXELCLIP. I had to comment out the one in...
