Thank's both of you! I didn't know that pygame uses 16 bits integers (I thought it was 32 bits every integer i put in the blit coordinates).
I already thought to blit only images which the rectangle of it is at least inside the screen resolution. (Excuse me for my english). For example (How do i input code by the way?): [code] for sprite in all_game_objects: if sprite.onScreen(): sprite.render(self.pygame_screen_surface) [/code] -- View this message in context: http://pygame-users.25799.x6.nabble.com/Blit-method-bug-tp3039p3042.html Sent from the pygame-users mailing list archive at Nabble.com.
