How do I get a rig to move in specified directions with animations?

Hey guys. I'm making a horror game called Navy Mission, and I'm putting in an army general to kind of guide the players through the game and accompany them all throughout the game. The problem is that I only know how to make a humanoid rig move around aimlessly, not in specified directions. I'm also trying to get it to move around with Rthro Animations. Does anyone know how to do that?

(Note: If you don't know what I'm trying to say, then I just kind of want him to work kind of like Park Ranger Daniel in the game Camping 2 by SAMSONXVI.)
