unity-unet-动态spawn player

连接服务器成功时，会在客户端生产一个player，这个player 的 prefab 可以在 Network Manager 中指定，如果不去重写一些方法的话，所有 player 生成的都是同一个 prefab 资源。

• 继承 Network Manager 重写 OnServerAddPlayer 方法，要自定义的prefab 一定要丢进注册列表中，也就是这个
  

  代码中是丢在这个容器中
  [SerializeField] List<GameObject> m_SpawnPrefabs = new List<GameObject>();
  但使用时是用
  public List<GameObject> spawnPrefabs { get { return m_SpawnPrefabs; }}

      /// <summary>    /// 重写实例化对象，使用自定义的prefab，这个prefab必须在spawnPrefabs列表中    /// </summary>    /// <param name="conn"></param>    /// <param name="playerControllerId"></param>    public override void OnServerAddPlayer(NetworkConnection conn, short playerControllerId)    {        GameObject go = null;        if (spawnPrefabs.Count > 0)            go = spawnPrefabs[spawnPrefabs.Count - 1];        else            go = playerPrefab;        var player = (GameObject)GameObject.Instantiate(go, GetStartPos().position, Quaternion.identity);        NetworkServer.AddPlayerForConnection(conn, player, playerControllerId);    }
