Hi, I modified the original MoveTowards action because I had the problem that when the assigned gameobject reached the target position, the action stopped working. Now it keeps going forever except that you select a finish event.
Not sure if it is the best way to do this, so I would appreciate any feedback, although it is working for me just fine.
