下面我們來講解事件層程式碼了哦！這個也比較難的哦！如果一會你實在看不懂理解不了也沒有關係，因為這些東西吧！只要會用就行，會和後端定協議就可以哦！協議一會我來教你怎麼定吧！首先我們來看看如何與後端定訊息哦！
這是一個列舉3型別，用來訂閱訊息的：
public enum CEventType
{
//----------------------- event ------------------------
GAME_OVER,
GAME_WIN,
GAME_LOAD_DATA,
//揹包相關的事件
/// <summary>
/// 請求得到所有的資料（剛開始的時候你肯定會向伺服器請求資料的) 說明：這個列舉就是表示我們前後端定的訊息，裡面包括前端自己定的訊息，已經前端和後端共同定的訊息。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;
/// <summary>
/// 委託
/// </summary>
/// <param name="evt"></param>
public delegate void CEventListenerDelegate(CBaseEvent evt);
public class CEventDispatcher
{
#region 事件單例
static CEventDispatcher instance;
public static CEventDispatcher GetInstance()
{
if (instance == null)
{
instance = new CEventDispatcher();
}
return instance;
}
#endregion
#region 存放所有事件的Hashtable表
/// <summary>
/// 存放所有事件的
/// </summary>
private Hashtable listeners = new Hashtable();
#endregion
#region 註冊偵聽事件
/// <summary>
/// 註冊偵聽
/// </summary>
/// <param name="eventType"></param>
/// <param name="listener"></param>
public void AddEventListener(CEventType eventType, CEventListenerDelegate listener)
{
//初始化一個事件物件ceventListenerDelegate
CEventListenerDelegate ceventListenerDelegate = this.listeners[eventType] as CEventListenerDelegate;
//給事件賦值
//Delegate.Combine (Delegate[]) 將委託陣列的呼叫列表連線在一起。
//Delegate.Combine 相當於事件的+=方法。
ceventListenerDelegate = (CEventListenerDelegate)Delegate.Combine(ceventListenerDelegate, listener);
this.listeners[eventType] = ceventListenerDelegate;
}
#endregion
#region 移除偵聽事件
/// <summary>
/// 移除偵聽
/// </summary>
/// <param name="eventType"></param>
/// <param name="listener"></param>
public void RemoveEventListener(CEventType eventType, CEventListenerDelegate listener)
{
CEventListenerDelegate ceventListenerDelegate = this.listeners[eventType] as CEventListenerDelegate;
if (ceventListenerDelegate != null)
{
ceventListenerDelegate = (CEventListenerDelegate)Delegate.Remove(ceventListenerDelegate, listener);
}
this.listeners[eventType] = ceventListenerDelegate;
}
#endregion
#region 派發事件
/// <summary>

/// </summary>
/// <param name="evt"></param>
public void DispatchEvent(CBaseEvent evt)
{

public void RemoveAll()
{

}
internal void DispatchEvent(CBaseEvent cBaseEvent, object saveData)
{
throw new NotImplementedException();
}
#endregion
}
using System.Collections;
using System.Collections.Generic;

}如果大家看了這麼多的程式碼還是不太理解的話，我們一會再開發揹包時會使用這些事件的哦！會用就行了哦！具體裡面怎麼寫的邏輯，不需要管，知道如何派發和偵聽事件就行了哦！
本篇小結：寫到這裡，框架的指令碼基本上都講解完了哦！不知道大家能夠理解多少呢！下篇部落格我會帶大家一起來完成一個揹包模組的開發哦！大家也可以自己去試試開發，看看你能否開發出來的哦！
