I am trying to use Ethan from the standard unity pack as well as his controller. I made a Cube that is his “Ground” , but he just floats there. and he does not move. I have unity installed on a external hard drive. I dont know if that makes a difference. The controller is unity’s as well. Im following Ben’s RPG course and his works right out of the box. I have the newest 2018 unity version. What am I doing wrong
