 using UnityEngine;
 using System.Collections;
 using UnityStandardAssets.CrossPlatformInput;
 public class PlayerNetworkMover : Photon.MonoBehaviour {
       public string playerName;
       private Transform _transformCacheName;

       void Start ()

     string playerName;
 
     void Update () {
         //playerName = GameControl.control.c_id;
         GetComponent<TextMesh> ().text = playerName;
 
     }
     
 }
