Question

我一直以多种不同的方式来解决这个问题。我在获取和设置本地自定义属性时遇到了麻烦。我正在尝试选择两个不同的团队（玩家和天使）。每个玩家都是作为旁观者开始的。一旦有足够多的人加入会议室，每个人都将被分配为玩家。然后，一定比例的玩家被选为天使。我之前进行过调整，以包含SetCustomProperties。但是，我不完全确定从这里出发。（实际上感觉就像我在黑暗中射击。）下面的代码段。

RoundSystem.cs中的代码段：

void Update()
    {
        playerCount = PhotonNetwork.PlayerList.Length;
        if (playerCount > 2 && enoughPlayers == false)
        {
            enoughPlayers = true;
            StartCoroutine(GameLoop());
        }
    }

    private IEnumerator GameLoop()
    {
        yield return StartCoroutine(TeamBalance());

        if (playerCount > 2)
        {
            // StartCoroutine(GameLoop());
            // Commented this because I don't want to the WIP game loop to ACTUALLY loop yet
        } else
        {
            enoughPlayers = false;
        }
    }

    private IEnumerator TeamBalance()
    {
        angelCount = Mathf.Floor(PhotonNetwork.PlayerList.Length * angelPercent);
        currentAngels = angelCount;
        currentPlayers = PhotonNetwork.PlayerList.Length;

        foreach (var item in PhotonNetwork.PlayerList)
        {
            Debug.Log("User changed to Citizen.");
            //SetCustomProperties of team to citiString
            photonView.RPC("SetPlayerTeam", item, citiString);
        }

        for (int i = 0; i < angelCount;)
        {
            var item = PhotonNetwork.PlayerList[Random.Range(0, PhotonNetwork.PlayerList.Length)];

            if (item.CustomProperties["team"].ToString().Equals(citiString))
            {
                Debug.Log("User changed to Angel.");
                //SetCustomProperties of team to angelString
                photonView.RPC("SetPlayerTeam", item, angelString);
                i++;
            }
        }

        yield return null;
    }

PlayerController.cs中的代码段：

[PunRPC]
        public void SetPlayerTeam(string teamString)
        {
            hash.Add("team", teamString);
            PhotonNetwork.LocalPlayer.SetCustomProperties(hash);
        }

所有球员都成功地成为观众，但是他们的球队都没有改变。我现在继续得到的错误是

NullReferenceException：对象引用未设置为对象的实例 ...（位于Assets / Scripts / RoundSystem.cs：78）

PhotonView对象引用未设置为对象的实例
