MsgDispatcher.cs:

using System;
    using System.Collections.Generic;
    using UnityEngine;
    
    namespace LJFramework
    {
        public class MsgDispatcher : MonoBehaviour
        {
            static Dictionary<string, Action<object>> mRegisteredMsgs = new Dictionary<string, Action<object>>();
            public static void Register(string msgName, Action<object> onMsgRecieved)  //注册消息

                    mRegisteredMsgs.Add(msgName, _ => { });
                }
                mRegisteredMsgs[msgName] += onMsgRecieved;
            }

            {

            {
                if (mRegisteredMsgs.ContainsKey(msgName))
                {
