How to animate this player correctly in my nodejs proyect

Questions
1

I have the following code on github repository:
DrFrankxio/node.mc.js-v5
The question is:
When I try to move the character, i can move it with x angle of the camera, but moving the head with y angle of the camera or move the legs or arms makes so hard for me. Any solution? Thanks anyway.
