Rotate character in 3D platformer

Hey guys, so I'm building a 3D (what I guess is 2.5D really) platformer but having a bit of trouble with the character control. I am using basic shapes at the moment, so a capsule with a character controller on it, and some cubes for the level. I can move left and right, and jump just fine so the actual movement is not at all an issue. What I am unable to figure out (and may not be possible) is rotating the capsule (to be replaced with a model later) to look in the direction he's going. I tried googling, other answers on here, and youtube and can't seem to find one specific to my issue. Here is what I have so far. public class PlayerController : MonoBehaviour { [Range(1.0f, 10.0f)] public float movementSpeed = 1.0f; [Range(1.0f, 15.0f)] public float jumpSpeed = 8.0f; [Range(1.0f, 30.0f)] public float gravity = 20.0f; private Vector3 moveDirection = Vector3.zero; private CharacterController controller; // Use this for initialization void Start () { controller = GetComponent(); } // Update is called once per frame void Update () { // if we are on the ground if(controller.isGrounded) { // we are on the ground so calculate the direction moveDirection = new Vector3(Input.GetAxis("Horizontal") * movementSpeed, 0, 0); moveDirection = transform.TransformDirection(moveDirection); // jump if(Input.GetButton("Jump")) moveDirection.y = jumpSpeed; } // apply gravity moveDirection.y -= gravity * Time.deltaTime; // move controller.Move (moveDirection * Time.deltaTime); // kill us at the bottom... if(transform.position.y
