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);
    }

源码:
        void OnServerAddPlayerInternal(NetworkConnection conn, short playerControllerId)
        {
            if (m_PlayerPrefab == null)
            {
                if (LogFilter.logError) { Debug.LogError("The PlayerPrefab is empty on the NetworkManager. Please setup a PlayerPrefab object."); }
                return;
            }
            if (m_PlayerPrefab.GetComponent<NetworkIdentity>() == null)
            {
                if (LogFilter.logError) { Debug.LogError("The PlayerPrefab does not have a NetworkIdentity. Please add a NetworkIdentity to the player prefab."); }
                return;
            }
            if (playerControllerId < conn.playerControllers.Count  && conn.playerControllers[playerControllerId].IsValid && conn.playerControllers[playerControllerId].gameObject != null)
            {
                if (LogFilter.logError) { Debug.LogError("There is already a player at that playerControllerId for this connections."); }
                return;
            }
            GameObject player;
            Transform startPos = GetStartPosition();
            if (startPos != null)
            {
                player = (GameObject)Instantiate(m_PlayerPrefab, startPos.position, startPos.rotation);
            }
            else
            {
                player = (GameObject)Instantiate(m_PlayerPrefab, Vector3.zero, Quaternion.identity);
            }
            NetworkServer.AddPlayerForConnection(conn, player, playerControllerId);
        }
