Hi. If you draw a thick line (more than 1 in width) at certain angles, you get empty spaces inside the line. Also, the line not always has the same thick at different angles. Check http://primates.ximian.com/~arturo/public_html/Junk/game-01.py for a demo. Greetings, Arturo ____________________________________ pygame mailing list pygame-users@seul.org http://pygame.seul.org
