上一個做的飛碟游戲雖然是功能也齊全，但是我感覺架構不是很好有點紊亂，不利于后期維護以及改進，所以我按照一個完整的架構重新做了一次，思路更清晰，而且還添加了更多的功能。這次的飛碟游戲是兩個關卡，50分上第二關，100分通第二關，而且可以任意切換模式（運動學非剛體模式和物理剛體模式，前者沒有剛體組件，后者加剛體組件）

講講規則先：一開始就是第一關，默認模式為運動學非剛體模式，還是按空格發射飛碟（一次一個），一個發射期間不能發射第二個，一個飛碟如果沒打中會在一定時間內消失，飛碟消失才能發射下一個飛碟，鼠標左鍵射擊子彈，按數字鍵2切換模式為物理剛體模式，按數字鍵1切換到運動學非剛體模式。

上個效果圖（由于比較難射中，所以我把飛碟大小弄大一些，分數顯示被遮住了）：

接下來講一下設計思路，游戲架構如下

DiskModule類掛在飛碟預設上，用來處理觸發器事件（飛碟碰到子彈或者地板時觸發）

DiskFactory類專門生產飛碟，所有生產飛碟的細節都在這里實現，會根據每個關卡生產不同大小以及顏色的飛碟，并且回收飛碟以便再次加以利用

Recorder類只負責記錄分數或者重置分數

Userface類處理用戶界面邏輯

CCActionManager類實現運動學的動作，比如運動學非剛體的飛碟發射

PhysicsActionManager類實現物理剛體學動作，比如子彈的發射以及剛體飛碟的發射

SceneController類加載場景以及調用各個其他類來實現功能，比如Userface調用子彈或者飛碟射擊要通過SceneController根據不同模式以及關卡來調用相應的動作管理器

具體代碼如下，（注釋已經把代碼思想寫的很清楚）：
