There's not much else to do to it other than do the pathfinding, and movement differently.
I was hoping there would be an easier way to address those issues using the existing plug, like a change in how the movement is done, but official plugin work is on hold while they figure out C3. Aka no editor based paths, and then I'm not going to use third party plugs in something I sell in the Scirra store.
I have figured out a way to deal with it, but it would mean not using the movement part of the plug, which seems kind of backwards.
Plus it's kind of mathy, and the idea of the template was to make it easy as possible.
If I were to make such a change I would sell it separately, but include it in the existing template for people who have already purchased that to download.
