代碼自定義生成玩家。
數據的同步問題。

OnMatchJoined：當假如比賽時調用

0X01 自定義生成玩家（位置）

自定義生成玩家即自定義位置，顏色，標籤等不同的玩家。如果我們想做一些對戰的小遊戲可以參考。

在Hierarchy中創建一個空物體用來放玩家出生點，自定義命名（例子爲：SpawnPoints）。
在SpawnPoints中添加相應的點（自定義命名，自定義位置）並添加NetworkStartPosition組件。如圖所示：
重寫了NetworkManager腳本，代碼如下：

public class MyNetWorkManager : NetworkManager
{
    #region 字段
    private short _tempIdCount = 1;
    //private int _tempCamDepthCount = 4;
    private NetworkStartPosition[] _spawnPoints;
    #endregion

    #region 系統方法
    // Use this for initialization
    void Start()
    {
        _spawnPoints = FindObjectsOfType<NetworkStartPosition>();

        #region 測試
        //foreach (var item in _spawnPoints)
        //{
        //    Debug.Log(item.name);
        //}
        #endregion
    }
    #endregion

    #region NetWork方法
    /// <summary>
    /// 添加玩家
    /// </summary>
    /// <param name="conn">連接方式</param>
    /// <param name="playerControllerId">玩家id</param>
    public override void OnServerAddPlayer(NetworkConnection conn, short playerControllerId)
    {
        playerControllerId = _tempIdCount;
        GameObject player = (GameObject)Instantiate(playerPrefab, Vector3.zero, Quaternion.identity);
        player.name = "Player_" + playerControllerId;

        if (_spawnPoints != null)
        {
            player.transform.position = _spawnPoints[playerControllerId - 1].transform.position;
            player.transform.rotation = _spawnPoints[playerControllerId - 1].transform.rotation;
        }
        NetworkServer.AddPlayerForConnection(conn, player, playerControllerId);
        _tempIdCount += 1;
        // _tempCamDepthCount -= 1;
    }
    #endregion
 #region 私有方法
    /// <summary>
    /// 設置同步變量初始化值
    /// </summary>
    /// <param name="tempObj">實例的物體</param>
    /// <param name="_syncColor">顏色</param>
    /// <param name="layerInt">j20父物體層</param>
    /// <param name="layerInt_Collider">雷達碰撞層</param>
    /// <param name="layerInt_Receive">雷達接收層</param>
    /// <param name="tagStr">j20父物體標籤</param>
    /// <param name="missileStr">導彈池對應字符串</param>
    /// <param name="fireStr">開火池對應字符串</param>
    void SetSyncVariable(GameObject tempObj, Color _syncColor, int layerInt, int layerInt_Collider, int layerInt_Receive, string tagStr, string missileStr, string fireStr)
    {
        tempObj.GetComponent<FighterSyncControl>()._syncColor = _syncColor;
        tempObj.GetComponent<FighterSyncControl>()._syncLayerInt = layerInt;
        tempObj.GetComponent<FighterSyncControl>()._syncLayerInt_Collider = layerInt_Collider;
        tempObj.GetComponent<FighterSyncControl>()._syncLayerInt_Receive = layerInt_Receive;
        tempObj.GetComponent<FighterSyncControl>()._syncTagStr = tagStr;
        tempObj.GetComponentInChildren<FighterSyncControl>()._syncMissilePoolStr = missileStr;
        tempObj.GetComponentInChildren<FighterSyncControl>()._syncFilePoolStr = fireStr;
    }
    #endregion
}

在每次加入玩家的時候都會根據位置點，自定義初始位置，效果如圖所示：

0X03 自定義其他變量

自定義顏色，標籤，層
修改上面自定義玩家的腳本，新增一些內容，如下:

 /// <summary>
    /// 添加玩家
    /// </summary>
    /// <param name="conn">連接方式</param>
    /// <param name="playerControllerId">玩家id</param>
    public override void OnServerAddPlayer(NetworkConnection conn, short playerControllerId)
    {
        playerControllerId = _tempIdCount;
        GameObject player = (GameObject)Instantiate(playerPrefab, Vector3.zero, Quaternion.identity);
        switch (playerControllerId)
        {
            case 1:
                SetSyncVariable(player, Color.red, 11, 14, 19, "Friendly", "missile_Instantiate_f", "Particle_missile_fire_f");
                break;
            case 2:
                SetSyncVariable(player, Color.blue, 15, 13, 17, "Enemy", "missile_Instantiate_e", "Particle_missile_fire_e");

                break;
            case 3:
                SetSyncVariable(player, Color.blue, 15, 13, 17, "Enemy", "missile_Instantiate_e", "Particle_missile_fire_e");

                break;
            case 4:
                SetSyncVariable(player, Color.red, 11, 14, 19, "Friendly", "missile_Instantiate_f", "Particle_missile_fire_f");
                break;
            default:
                break;
        }
        player.name = "Player_" + playerControllerId;

        if (_spawnPoints != null)
        {
            player.transform.position = _spawnPoints[playerControllerId - 1].transform.position;
            player.transform.rotation = _spawnPoints[playerControllerId - 1].transform.rotation;
        }
        NetworkServer.AddPlayerForConnection(conn, player, playerControllerId);
        _tempIdCount += 1;
        // _tempCamDepthCount -= 1;
    }

效果如圖所示：

如圖可見已經修改成功，下一步就是測試數據是否同步。

0X04 數據同步

首先寫一個飛機接收同步數據的腳本，並且並掛載在飛機身上，自定義命名（例子名稱：FighterSyncControl）代碼如下：

public class FighterSyncControl : NetworkBehaviour
{

    #region 變量
    private Transform[] allObj;
    private GameObject curFighter;

    #region 飛機同步變量
    [SyncVar] [HideInInspector] public Color _syncColor;        // 顏色

    // 同步標籤和層
    [SyncVar] [HideInInspector] public int _syncLayerInt;
    [SyncVar] [HideInInspector] public int _syncLayerInt_Collider;
    [SyncVar] [HideInInspector] public int _syncLayerInt_Receive;
    [SyncVar] [HideInInspector] public string _syncTagStr;
    [SyncVar] [HideInInspector] public int _syncDefTagStr;
    [SyncVar] [HideInInspector] public string _syncDefLayerInt;

    // 腳本變量
    [SyncVar] [HideInInspector] public string _syncMissilePoolStr;
    [SyncVar] [HideInInspector] public string _syncFilePoolStr;
    #endregion

    #endregion

    #region 系統方法
    private void Awake()
    {
        curFighter = gameObject.GetComponentInChildren<UI_show_info_a>().gameObject;
    }

    // Use this for initialization
    void Start()
    {

        allObj = curFighter.GetComponentsInChildren<Transform>(true);
        foreach (Transform item in allObj)
        {
            SetRedOrBule(_syncLayerInt, _syncTagStr, _syncLayerInt_Collider, _syncLayerInt_Receive, _syncMissilePoolStr, _syncFilePoolStr);
        }

        SetScriptVariable(_syncColor);

    }

    // Update is called once per frame
    void Update()
    {
        #region 測試
        if (Input.GetMouseButtonDown(0))
        {//判斷鼠標是否按下
            // 從攝像機開始，到屏幕觸摸點，發出一條射線
            Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
            // 撞擊到了哪個3D物體
            RaycastHit hit;
            if (Physics.Raycast(ray, out hit))
            {
                Debug.Log(hit.transform.tag);//打印出碰撞到的節點的名字
            }
        }
        #endregion
    }

    #endregion

    
    /// <summary>
    ///  設置紅藍
    /// </summary>
    /// <param name="layerInt">層值</param>
    /// <param name="tagStr">標籤值</param>
    private void SetRedOrBule(int j20_layerInt, string tagStr, int radaCollider_layerInt, int radaRec_layerInt, string missileStr, string fireStr)
    {
        foreach (Transform item in allObj)
        {
            // 測試：單獨給某個賦值
            if (item.name.Equals("J20_beta"))
            {
                item.gameObject.tag = tagStr;
                item.gameObject.layer = j20_layerInt;
            }
            if (item.name.Equals("rada_scan_collider"))
            {
                item.gameObject.layer = radaCollider_layerInt;
            }
            if (item.name.Equals("rada_receive_collider"))
            {
                item.gameObject.layer = radaRec_layerInt;
            }
        }
        curFighter.GetComponent<UI_show_info_a>().missile_inpool = missileStr;
        curFighter.GetComponent<UI_show_info_a>().fire_inpool = fireStr;
    }

    /// <summary>
    /// 給固定的腳本變量賦值（同步變量）
    /// </summary>
    private void SetScriptVariable(Color tempColor)
    {
        curFighter.transform.Find("fighter_blue_type_f22").GetComponent<MeshRenderer>().material.color = tempColor;
    }
}

現在我們可以運行測試了，測試效果如下圖所示：
