Unity Mirror Networking InvalidCastException：指定的演员表无效

Question

我试图创建一个自定义玩家生成器，但一直遇到

"指定的演员表无效

尝试在网上搜索，但所有结果都没有用，所以希望这里有人可以帮助我。

问题行：

NetworkServer.AddPlayerForConnection(conn, playerobject); 

....是发生错误。 （以下为完整错误）

代码：

public override void OnClientConnect(NetworkConnection conn)
{
    var connection = conn;
    connlist.Add(connection);

    if (!clientLoadedScene)
    {
        if (!NetworkClient.ready) NetworkClient.Ready();
        {
            GameObject playerobject = (GameObject)Instantiate(Player, new Vector3(0, 0, 0), new Quaternion(0, 0, 0, 0));
            playerobject.GetComponent<PlayerManager>().PlayerName = nameplayer;
            NetworkServer.AddPlayerForConnection(conn, playerobject);
            Debug.Log(nameplayer + " is spawned!");
        }
    }

    base.OnClientConnect(conn);
}

错误满：

InvalidCastException: 指定的强制转换无效。 Mirror.NetworkIdentity.SetClientOwner (Mirror.NetworkConnection conn) (at Assets/Mirror/Runtime/NetworkIdentity.cs:250) Mirror.NetworkServer.AddPlayerForConnection (Mirror.NetworkConnection conn, UnityEngine.GameObject player) (at Assets/Mirror/Runtime/NetworkServer .cs:617) NetManager.OnClientConnect (Mirror.NetworkConnection conn) (at Assets/Scripts/NetManager.cs:58) Mirror.NetworkManager.OnClientAuthenticated (Mirror.NetworkConnection conn) (at Assets/Mirror/Runtime/NetworkManager.cs:1158 ) Mirror.NetworkManager.OnClientConnectInternal() (at Assets/Mirror/Runtime/NetworkManager.cs:1142) Mirror.LocalConnectionToServer.Update() (at Assets/Mirror/Runtime/LocalConnections.cs:84) Mirror.NetworkClient.NetworkLateUpdate() （在 Assets/Mirror/Runtime/NetworkClient.cs:1249）Mirror.NetworkLoop.NetworkLateUpdate () （在 Assets/Mirror/Runtime/NetworkLoop.cs:189）

我不确定您在哪一行遇到错误，但我记得Instantiate()方法返回了一个GameObject因此您不需要GameObject转换它，另外您不应该将连接var存储在一个列表，如果你打算保留它，你修改后的代码应该是这样的：

public override void OnClientConnect(NetworkConnection conn)
{
    connlist.Add(conn);

    if (!clientLoadedScene)
    {
        if (!NetworkClient.ready) NetworkClient.Ready();
        {
            var playerobject = Instantiate(Player, new Vector3(0, 0, 0), new Quaternion(0, 0, 0, 0));
            playerobject.GetComponent<PlayerManager>().PlayerName = nameplayer;
            NetworkServer.AddPlayerForConnection(conn, playerobject);
            Debug.Log(nameplayer + " is spawned!");
        }
    }

    base.OnClientConnect(conn);
}

我找到了一个解决方案，我将我的 Spawn 代码移到了一个函数，即 OnServerAddPlayer 而不是 OnClientConnect 它修复了所有问题并且效果惊人！
