I've been searching for a way to do this for a while, and can't seem to find it. What I'm trying to do is have an NPC wander in a waiting room. I need him to walk to a vending machine, use it, walk to a sofa, sit and eat the food, walk to a water cooler, and drink water. Then repeat the process. The problem I'm having is doing all of this in the background, so you can still move around while this guy is wandering. Does anybody know how to solve this problem?
