Hi!
I'm sorry I'm not very good at making videos but hopefully this will still be helpful.
Where have you got so far with Path? As a starting point, you probably want to set something up like the "Follower animation demo" in the Path documentation. Essentially, copying what's there and changing the art to suit your purposes. There's an associated contraption that you'll need to import into your own deck to make this work.
The next part is making things trigger based on the movement. There's not really any set way to do this, but one way to do it is that when the follower has stopped walking, it calls a finish[] event, and you can put code in that event to check where the follower's current position is and make events happen accordingly.
I'm not sure if this makes much more sense than the tutorial, but if you can let me know which parts make sense and which parts don't we may be able to work it out.
