Hi,
If you create a one state fsm, and inside it have your set of actions to follow a gameobject, it will run endlessly.
Here is something to try:
Create a fsm on the object that need to follow another.
On the start state, add a moveTowards action.
In that MoveTowards action, set the target object to the game object you want to follow.
This is sufficient to have the ball running. when you hit play, that fsm state will run continously and have its gameobject follow the target object defined in the MoveTowards action.
If you can't get that to run, post a reply, and I'll make a working example.
Bye,
Jean
