Unity 跨線程交互

Internal_CreateGameObject can only be called from the main thread

Unity的UI線程不允許其他線程訪問，但是logger線程是獨立的，所以如果你成功的輸出了日志，並不代表你就能快樂的訪問ui了

但是有的時候會出現不報錯，但是毫無反饋的情況，基本上也是同樣的問題造成的。

You can't access the Unity API from any thread outside of the main execution thread of Unity.

If you need data from Unity for a thread, you'll need to gather said information as a token and pass it along to the thread.

        class EventPacker
        {
            public MessageListener handler;
            public IMessage content;
        }
        public void Dispatch(eMessage id, IMessage message)
        {
            MessageListener handlers = null;

            if (SafeMessageListener.TryGetValue(id, out handlers))
            {
                if (handlers != null)
                {
                    EventQueue.Enqueue(new EventPacker { handler = handlers, content = message });
                }
            }
        }

        /// <summary>
        /// 只能由主線程來調用
        /// </summary>
        public void Update()
        {
            if (EventQueue.Count > 0)
            {
                var pack = EventQueue.Dequeue();
                pack.handler.Invoke(pack.content);
            }
        }

 

其實解決也很簡單，在任何一個MonoBehavior的update中調用上面的方法就可以了。
