It's me again =P

So basically I have this boss with Three Phases in my game, and during phase 3 he starts to run around, ideally on a set path made in WED, in the direction of the player. I have the boss, a path, and the player in the level. And I am trying to use path_scan to get him onto the path, the only problem is I dont know if its working because Im not sure how to get him to actually move along that path towards the player. The help files i was reading on this assume taht I have some functions already made, which i unfortunatly dont.
