I've followed this tutorial, but units with this behavior seem to get severed from their actor. It's very strange. The actor still plays its animations (attacks if the unit is attacking, walks if the unit is moving)- however the the actor will not move. Meanwhile the unit can move, and get attacked independently from the actor.
I apologize for bumping an old thread, but could anyone help with making a shape roll? I want to make a basketball roll but I can't get it to rotate around its center. I copied the banshee rollcopter behaviors and things exactly and it works great for air units (banshees, void rays, etc.) but when applied to a ground unit it rolls the entire unit around the point of its feet. Even changing the model of an air unit's actor to the basketball has this same problem. My guess is that the model itself needs to be modified, but I haven't had any luck so far.
