Hi, i've made a multiplayer photon script but it controls every player in the server, how to control only my player?

    using UnityEngine;
    using System.Collections;

    namespace UnityStandardAssets.Characters.FirstPerson{

     public class Networking : Photon.MonoBehaviour {

 // Use this for initialization
 void Start () {
     PhotonNetwork.ConnectUsingSettings ("RP_v013");
     
     Cursor.lockState = CursorLockMode.Locked;
     Cursor.visible = (false);

     enabled = photonView.isMine;
 
 }
 
 // Update is called once per frame
 void Update () {
     Cursor.lockState = CursorLockMode.Locked;
     Cursor.visible = (false);

 }
 
 void OnGUI() {
     GUILayout.Label (PhotonNetwork.connectionStateDetailed.ToString ());
     if (Input.GetKey(KeyCode.Escape))
     {
         PhotonNetwork.LoadLevel("MainMenu");
     }
 }
 
 
 void OnConnectedToMaster() {
     PhotonNetwork.JoinRandomRoom ();
 }
 
 void OnPhotonRandomJoinFailed() {
     PhotonNetwork.CreateRoom (null);
 }
 
 void OnJoinedRoom() {
     GameObject myPlayerGO = (GameObject)PhotonNetwork.Instantiate ("PlayerPrefab", Vector3.zero, Quaternion.identity, 0);
     PhotonNetwork.automaticallySyncScene = true;
     
     
 }
  }
 }
