Character facing world z direction when stop moving?

hello there i have problem hope to find help to understand how to fix it
my problem is when the character stop moving it always change the direction it face to the world z direction
i really cant figure it out how to fix
i tried lookat() but this end that he never face the direction when moving

the code i use

Code (CSharp):

1. public class MovementController : MonoBehaviour
2. {
3.     Vector3 _CharacterDirection;
4.     Quaternion _CharacterRotation=Quaternion.identity,_Look;
5.     Animator _CharacterAnim;
6.     Rigidbody _CharacterRigidbody;
7.     public float TurnSpeed;
8.  
9.     void Start()
10.     {
11.         _CharacterAnim = GetComponent<Animator>();
12.         _CharacterRigidbody = GetComponent<Rigidbody>();
13.     }
14.  
15.     void FixedUpdate()
16.     {
17.         CharacterMovement();
18.     }
19.  
20.     void CharacterMovement()
21.     {
22.         float h = Input.GetAxis("Horizontal");
23.         float v = Input.GetAxis("Vertical");
24.         _CharacterDirection.Set(h, 0, v);
25.         _CharacterDirection.Normalize();
26.  
27.         bool _IsHorizontalChange = !Mathf.Approximately(h, 0f);
28.         bool _IsVerticalChange = !Mathf.Approximately(v, 0);
29.         bool _IsWalking = _IsHorizontalChange || _IsVerticalChange;
30.         _CharacterAnim.SetBool("IsWalking", _IsWalking);
31.  
32.          Vector3 _DesairdForward = Vector3.RotateTowards(Vector3.forward, _CharacterDirection, TurnSpeed * Time.deltaTime, 0);
33.         _CharacterRotation = Quaternion.LookRotation(_DesairdForward);
34.        
35.  
36.         _CharacterRigidbody.MovePosition(_CharacterRigidbody.position + _CharacterDirection * Time.deltaTime);
37.         _CharacterRigidbody.MoveRotation(_CharacterRotation);
38.        
39.     }

 

In line 32 you specify _DesairdForward by using Vector3.forward. That's world Z direction. You probably want this.transform.forward

 

as i understand i use this to rotate the character while moving to make it face his z direction is this right??

 

thank you
