Hiya I read something the other day that said quake3 used pre defined paths (the floor is flaged a floor, I quess or walkable area) things such as lifts have the script attached to them that tells the AI how long to stay on the lift, or maybe a script attached to an area where the bot is expose to jump at. What I want to now though is if this technique COULD be used for outdoor worlds. I would say probably not, but im not sure. The thing is, in quake3, there were huge levels, and the bots could seemingly go anywhere! The reason I want to use this approach is because it seems the easiest. I normaly dont want to take the easy route, but im making an entire game engine so Im trying to cut my self a little bit of slack here Owell, guess its gamedev article searching I do!
