I am creating a 3rd person style game and I am having trouble getting the character to rotate to face the mouse. Can anyone help?

Here is the code, movement and all.

using UnityEngine;

public class PlayerMovement : MonoBehaviour { public float speed = 6f;

     Vector3 movement;
     Animator anim;
     Rigidbody playerRigidbody;
     int floorMask;
     float CamRayLength = 100f;

     void Awake()
     {
         floorMask = LayerMask.GetMask ("Floor");
         anim = GetComponent <Animator> ();
         playerRigidbody = GetComponent <Rigidbody> ();
     }

     void FixedUpdate()
     {
         float h = Input.GetAxisRaw ("Horizontal");
         float v = Input.GetAxisRaw ("Vertical");

         Move (h, v);
         Turning ();
         Animating (h, v);
     }

     void Move (float h, float v)
     {
         movement.Set (h, 0f, v);

         movement = movement.normalized * speed * Time.deltaTime;

         playerRigidbody.MovePosition (transform.position + movement);
     }

     void Turning()
     {
         Ray camRay = Camera.main.ScreenPointToRay (Input.mousePosition);

         RaycastHit floorHit;

         if (Physics.Raycast (camRay, out floorHit, CamRayLength, floorMask))
         {
             Vector3 playerToMouse = floorHit.point - transform.position;
             playerToMouse.y = 0f;

             Quaternion newRotation = Quaternion.LookRotation (playerToMouse);
             playerRigidbody.MoveRotation (newRotation);
         }
     }

     void Animating(float h, float v)
     {
         bool walking = h != 0f || v != 0f;
         anim.SetBool ("IsWalking", walking);
     }

}
