Integrating animation

Hello all!

I have progressed compared to https://blenderartists.org/t/how-do-i-attach-my-character-to-the-ground-in-my-game-so-it-can-walk/1189390 but the animation does not seem to be integrated with the controller like this demo: http://turingtester.gitlab.io/babylonjs-intro/demo/

This is where I am currently:
http://turingtester.gitlab.io/babylonjs-intro/demo2/

How do I integrate?
