GoF中定義：

定義一個(gè)接口來(lái)封裝一群對(duì)象的互動(dòng)行為

中介者通過(guò)移除對(duì)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(dòng)獨(dú)立性

?

游戲做的越大，系統(tǒng)劃分的也就越多

如事件系統(tǒng)，關(guān)卡系統(tǒng)，信息系統(tǒng)，界面系統(tǒng)等。

?

系統(tǒng)切分越細(xì)，就意味著系統(tǒng)之間的溝通越復(fù)雜

單一系統(tǒng)引入太多其他系統(tǒng)的功能，不利于單一系統(tǒng)的轉(zhuǎn)換和維護(hù)

單一系統(tǒng)被過(guò)多的系統(tǒng)所依賴，不利于接口的更改，容易牽一發(fā)而動(dòng)全身

由于需要提供給其他系統(tǒng)操作，系統(tǒng)的接口可能會(huì)過(guò)于龐大，不容易維護(hù)

先產(chǎn)生中介者ConcreteMediator的對(duì)象之后

接著產(chǎn)生兩個(gè)Colleague對(duì)象

并將其設(shè)置給中介者

分別調(diào)用兩個(gè)Colleague對(duì)象的Action方法

查看信息是否通過(guò)Mediator傳遞給Colleague
