my player look all clients mouse

my code:

public float speed;

void Start(){

     if(isLocalPlayer)
         GameObject.Find("Main Camera").GetComponent<Camera2DFollow>().target = transform;

 }

 void Update () {
 
     if (!isLocalPlayer)
         return;

     CmdLookMouse ();

     CmdWalk (0);
     if (Input.GetMouseButton (0))
         CmdWalk (speed);

 }

 [Command]
 void CmdWalk(float speed){

     Rigidbody2D rigidbody2d = GetComponent<Rigidbody2D>();
     rigidbody2d.velocity = transform.TransformDirection (Vector2.up * speed);

 }

 [Command]
 void CmdLookMouse(){

     Vector3 difference = Camera.main.ScreenToWorldPoint (Input.mousePosition) - transform.position;
     float rot_z = Mathf.Atan2 (difference.y, difference.x) * Mathf.Rad2Deg;
     transform.rotation = Quaternion.Euler (transform.rotation.x, transform.rotation.y, rot_z - 90);

 }
