问题描述
我正在努力将 
"Compiled sass\file.scss to css\filecompiled.css."
我正在使用 Mirror 创建一个大厅，当我尝试启动 UnityGGPO 时，我从该进程中提取连接信息。
UnityGGPO 包中附带了一个示例游戏“VectorWar”来展示如何使用它，VectorWar 不会导致此错误。 我的代码中导致此问题的调用如下所示：
MarshalDirectiveException: The type `System.Object' layout needs to be Sequential or Explicit
GGPO.StartSession (system.intPtr& session,system.intPtr beginGame,system.intPtr advanceFrame,system.intPtr loadGameState,system.intPtr logGameState,system.intPtr saveGameState,system.intPtr freeBuffer,system.intPtr onEvent,System.String game,system.int32 num_players,system.int32 localport) (at Assets/UnityGGPO/Scripts/GGPO.cs:240)

Mirror.NetworkClient.Update () (at Assets/Mirror/Runtime/NetworkClient.cs:263)

VectorWar 调用几乎相同：
var result = GGPO.Session.StartSession(begin_game_callback,advance_frame_callback,load_game_state_callback,log_game_state,save_game_state_callback,free_buffer_callback,OnEventConnectedToPeerDelegate,OnEventSynchronizingWithPeerDelegate,OnEventSynchronizedWithPeerDelegate,OnEventRunningDelegate,OnEventConnectionInterruptedDelegate,OnEventConnectionResumedDelegate,OnEventdisconnectedFromPeerDelegate,OnEventEventcodeTimesyncDelegate,"combat",num_players,localport);
这些函数回调也几乎相同（相同的返回类型、相同的参数、公共静态）并且在几乎相同的类中调用（公共静态类）。
现在我的理解是，这些都与我们的好朋友 Marshal 没有任何关系，但我之前并没有真正使用过 marshaler，当我检查发送到 .dll 的各个参数的布局时，它们都是“顺序或显式”。
我将继续深入研究 C++ 代码，以便对正在发送的地址之一进行可能的操作，但到目前为止，它们都只是回调，所以我看不出这对我来说与 VectorWar 有何不同。
如果您能深入了解与封送拆收器相关的人员会怀疑哪种环境属性，我们将不胜感激。
