非玩家对象的权限转移问题

我正在制作多人游戏,我想让玩家与非玩家对象互动(其变换可以由任何玩家更改)。当我与第一个加入游戏的玩家(或主持该游戏的人)互动时,但如果我尝试与另一位玩家(第二参与的玩家)互动,则对象会回到第一个玩家离开的位置他在。

所以我尝试的是转移非玩家对象的权限,但出现以下错误。 是否有人遇到相同的问题或知道其他方法可以完成上述任务?我正在使用以下代码更改权限:

    [Command]
void Cmd_AssignLocalAuthority(GameObject obj)
{
    print("shifting authority successfully");
    NetworkInstanceId nIns = obj.GetComponent<NetworkIdentity>().netId;
    GameObject client = NetworkServer.FindLocalObject(nIns);
    NetworkIdentity ni = client.GetComponent<NetworkIdentity>();
    ni.AssignClientAuthority(connectionToClient);
}

[Command]
void Cmd_RemoveLocalAuthority(GameObject obj)
{
    print("reverting authority successfully");
    NetworkInstanceId nIns = obj.GetComponent<NetworkIdentity>().netId;
    GameObject client = NetworkServer.FindLocalObject(nIns);
    NetworkIdentity ni = client.GetComponent<NetworkIdentity>();
    ni.RemoveClientAuthority(ni.clientAuthorityOwner);
}

我得到的错误是这个

您需要知道应该从玩家对象而不是对象本身调用更改,因为它没有权限。

要设置权限,您应该执行以下操作:

[Command]
public void CmdSetAuth(NetworkInstanceId objectId, NetworkIdentity player)
{
    GameObject iObject = NetworkServer.FindLocalObject(objectId);
    NetworkIdentity networkIdentity = iObject.GetComponent<NetworkIdentity>();

    //Checks if anyone else has authority and removes it and lastly gives the authority to the player who interacts with object
    NetworkConnection otherOwner = networkIdentity.clientAuthorityOwner;
    if (otherOwner == player.connectionToClient)
    {
        return;
    }
    else
    {
        if (otherOwner != null)
        {
            networkIdentity.RemoveClientAuthority(otherOwner);
        }
        networkIdentity.AssignClientAuthority(player.connectionToClient);
    }

    networkIdentity.AssignClientAuthority(player.connectionToClient);
}
