Greetings! I am doing a Dungeon Keeper 2 like test and I was wondering on how to do the dungeons. I am wanting it to where you can click on a block and remove it later on so I decided against BSP trees. So what should I do now? Should I make a map variable? float map[32][32]; Then do a visibility check on the tiles, so that the ones that aren''t seen or are too far away not to be drawn? (Speed is an issue) Thanks in advance! Justin Eslinger
