GoF中定義：

定義一個接口來封裝一群對象的互動行為

中介者通過移除對象之間的引用

以減少他們之間的耦合度

并且能改變它們之間的互動獨立性

?

游戲做的越大，系統劃分的也就越多

如事件系統，關卡系統，信息系統，界面系統等。

?

系統切分越細，就意味著系統之間的溝通越復雜

單一系統引入太多其他系統的功能，不利于單一系統的轉換和維護

單一系統被過多的系統所依賴，不利于接口的更改，容易牽一發而動全身

由于需要提供給其他系統操作，系統的接口可能會過于龐大，不容易維護

using UnityEngine;public abstract class Mediator {public abstract void SendMessage(Colleague theColleague,string Message);}public abstract class Colleague {protected Mediator m_Mediator = null;public Colleague(Mediator theMediator) {m_Mediator = theMediator;}public abstract void Request(string Message);}public class ConcreateColleague1 : Colleague {public ConcreateColleague1(Mediator theMediator) : base(theMediator) { }public void Action() {m_Mediator.SendMessage(this,"Colleage1發出通知");}public override void Request(string Message){Debug.Log("ConcreateColleague1.Request:" + Message);}}public class ConcreateColleague2 : Colleague{public ConcreateColleague2(Mediator theMediator) : base(theMediator) { }public void Action(){m_Mediator.SendMessage(this,"Colleage2發出通知");}public override void Request(string Message){Debug.Log("ConcreateColleague2.Request:" + Message);}}public class ConcreteMediator : Mediator {ConcreateColleague1 m_Colleague1 = null;ConcreateColleague2 m_Colleague2 = null;public void SetColleague1(ConcreateColleague1 theColleague) {m_Colleague1 = theColleague;}public void SetColleague2(ConcreateColleague2 theColleague) {m_Colleague2 = theColleague;}public override void SendMessage(Colleague theColleague, string Message){if (m_Colleague1 == theColleague)m_Colleague2.Request(Message);if (m_Colleague2 == theColleague)m_Colleague1.Request(Message);}}

?

先產生中介者ConcreteMediator的對象之后

接著產生兩個Colleague對象

并將其設置給中介者

分別調用兩個Colleague對象的Action方法

查看信息是否通過Mediator傳遞給Colleague
