Yeah, that could have worked if I had success getting multiplayer work.
That toggle is added in latest version. Animations for custom NPCs are there but code doesn't fully work.
Viewing post in Questions About the Scrapped Multiplayer Game and an animation.
That's cool, I love that you added modding support. I think I've seen some people having interest in creating ghosts and animations, hopefully we'll see some of those in the near future.
It's a shame multiplayer wasn't working, but it's understandable since I've always thought multiplayer would be hard to implement in any game. It's why once I get sufficient in coding, all my games will be single player, I don't want to deal with something like that.
