Hello, All. My name's Tom. I'm working on a project that may benefit from using an autopath, but I can't seem to find any information on the subject. It sounds as though you've all had some experience with it. Could you guys and girls take a minute to help me out? Here's what's going on: I have a ghost I want to be able to wander the hallways of a maze. Currently, I have invisible prims that detect collisions with the ghost and tell it when to turn. This works fine, assuming no one bumps into the ghost. If someone bumps into him and knocks him off his path, he'll crash into a wall and just stay there. I hoped I might be able to just make linear and angular deflection impossible, then let people bump into him to no effect. No luck with that - he could still be moved by avatars. So, is there a better way to make him stick to his path? If so, how should I begin?
