rotating the character based on mouse position

I’m following again the tutorial Survival Shooter but now using It in my own new project with new free assets and a new character. Although, besides working, It’s turning around another center. This center is right next to the player, like 1 or 2 metesr alway. I’ve checked the code which is the same as the tutorial and all player’s elements has its center correct. So basically I don’t know what else could be.

using UnityEngine;

public class PlayerMovement : MonoBehaviour
public float speed = 6f; // The speed that the player will move at.

Vector3 movement;                   // The vector to store the direction of the player's movement.
Animator anim;                      // Reference to the animator component.
Rigidbody playerRigidbody;          // Reference to the player's rigidbody.
int floorMask;                      // A layer mask so that a ray can be cast just at gameobjects on the floor layer.
float camRayLength = 100f;          // The length of the ray from the camera into the scene.

void Awake ()
    // Create a layer mask for the floor layer.
    floorMask = LayerMask.GetMask ("Floor");

    // Set up references.
    anim = GetComponent <Animator> ();
    playerRigidbody = GetComponent <Rigidbody> ();

void FixedUpdate ()
    // Store the input axes.
    float h = Input.GetAxisRaw ("Horizontal");
    float v = Input.GetAxisRaw ("Vertical");

    // Move the player around the scene.
    Move (h, v);

    // Turn the player to face the mouse cursor.
    Turning ();

    // Animate the player.
    Animating (h, v);

void Move (float h, float v)
    // Set the movement vector based on the axis input.
    movement.Set (h, 0f, v);
    // Normalise the movement vector and make it proportional to the speed per second.
    movement = movement.normalized * speed * Time.deltaTime;

    // Move the player to it's current position plus the movement.
    playerRigidbody.MovePosition (transform.position + movement);

void Turning ()
    // Create a ray from the mouse cursor on screen in the direction of the camera.
    Ray camRay = Camera.main.ScreenPointToRay (Input.mousePosition);

    // Create a RaycastHit variable to store information about what was hit by the ray.
    RaycastHit floorHit;

    // Perform the raycast and if it hits something on the floor layer...
    if(Physics.Raycast (camRay, out floorHit, camRayLength, floorMask))
        // Create a vector from the player to the point on the floor the raycast from the mouse hit.
        Vector3 playerToMouse = floorHit.point - transform.position;

        // Ensure the vector is entirely along the floor plane.
        playerToMouse.y = 0f;

        // Create a quaternion (rotation) based on looking down the vector from the player to the mouse.
        Quaternion newRotation = Quaternion.LookRotation (playerToMouse);

        // Set the player's rotation to this new rotation.
        playerRigidbody.MoveRotation (newRotation);

void Animating (float h, float v)
    // Create a boolean that is true if either of the input axes is non-zero.
    bool walking = h != 0f || v != 0f;

    // Tell the animator whether or not the player is walking.
    anim.SetBool ("IsWalking", walking);


I’ve just notice that the problem was my floor (the mask which the ray collides with) which wasnt at 0 position on Y axis. Although when I walk in to a ground elevation the center starts to get off of my character. So what should I do? Move the floor(the mask not the actual world ground) along with the character?
