Unity Networking：当客户端首先加载场景时，网络对象不会出现在客户端上

Question

我在多人游戏中遇到了对象实例化的问题。游戏布局很简单：玩家进入大厅，一旦每个人都标记准备就绪，倒计时和LobbyManager来电ServerChangeScene(gameScene)来加载游戏等级。问题是在很多负载上，所有联网对象都没有在客户端上实例化。经过一些游戏测试后，我注意到这似乎只发生在client在服务器之前加载场景时 - 当server加载时，所有内容都正确显示并且游戏正常播放。有没有办法确保服务器首先加载？

一些参考代码：

 public override void OnLobbyServerPlayersReady()
 {
     currentNumberTeam1 = 0;
     currentNumberTeam2 = 0;
     StartCoroutine(ServerCountdownCoroutine());
 }
 public IEnumerator ServerCountdownCoroutine()
 {
     float remainingTime = _matchStartCountdown;
     int floorTime = Mathf.FloorToInt(remainingTime);
     while (remainingTime > 0)
     {
         yield return null;
         remainingTime -= Time.deltaTime;
         int newFloorTime = Mathf.FloorToInt(remainingTime);
         if (newFloorTime != floorTime)
         {
             floorTime = newFloorTime;
             for (int i = 0; i < lobbySlots.Length; ++i)
             {
                 if (lobbySlots[i] != null)
                 {
                     (lobbySlots[i] as CharacterSelect).RpcUpdateCountdown(floorTime);
                 }
             }
         }
     }
     for (int i = 0; i < lobbySlots.Length; ++i)
     {
         if (lobbySlots[i] != null)
         {
             (lobbySlots[i] as CharacterSelect).RpcUpdateCountdown(0);
         }
     }

     ServerChangeScene(playScene);
 }
