Question How to animate with 3D velocity

I am trying to make an animation play for each possible velocity I have, but I am using a 3D space, with a 2D sprite, how would I make the sprite play a different animation based on the Z velocity?

 

Bump

 

old post but maybe that still works?

Idk if that will help, I am trying to make a 2D object animate properly in a 3D scene, and I want it to have a different animation for walking forwards/backwards and walking to the left/right.
