Is there a way to allow the user to use the keys to move as though they were walking on the ground looking straight ahead. Basically I want to go to a 3D view, snap the the user to the elevation, have them looking straight, and if they use the arrow forward(up)/back(down) arrow keys then it moves them along the ground rather than through the elevation (hills etc). Also if they use the left or right arrow keys I still want that to turn left/right so that they can look around and change directions.
