簡單打飛碟小游戲
游戲規則與要求
規則
鼠標點擊飛碟，即可獲得分數，不同飛碟分數不一樣，飛碟的初始位置與飛行速度隨機，隨著分數增加，游戲難度增加。初始時每個玩家都有6條生命，漏打飛碟扣除一條生命，直到生命為0游戲結束。
要求：
使用帶緩存的工廠模式管理不同飛碟的生產與回收，該工廠必須是場景單實例的！具體實現見參考資源 Singleton 模板類
近可能使用前面 MVC 結構實現人機交互與游戲模型分離
擴展：
實現：
第一階段做的井字棋還是能了解透徹的，Homework2的MVC架構和Homework3里的動作分離管理開始吃力了，說實話，現在對動作分離管理還不怎么理解透，但還是能理解MVC了。所以這次作業我并沒有用到動作分離管理，只是用了MVC架構，也只是簡單的MVC，所以沒有SSDirector類了，當然，還有這周要求的工廠模式也是有的。
之前兩次作業看了不少博客，感覺類與類之間的交叉很多，雖然有了MVC和動作管理，但我看得結構不是很清晰（好吧，可能是我能力的問題）。這次我學會了兩個很基礎但很好用的兩個方法（原諒我到了現在才會。。。）——對象gameObject（注意g是小寫不是大寫）和GetComponent<>()，之前我一直想著用C++里面的方法實現封裝，即該方法或動作是屬于哪個類的就放在它里面，一個類不要去操作另一個類，可以通過函數調用。講一下gameObject和GetComponent吧
- GetComponent：先說這個比較好，我們創建每個游戲對象都是用GameObject的了，但不同對象有不同的方法和屬性，所以就可以自己寫腳本掛到物體上，讓它實現你想要的方法。當然，通過這個方法也可以添加其它組件比如Rigibody 。
- gameObject：這是GameObject的實例，但它是ReadOnly即只讀，它有什么用呢，當你把一個組件（這里重點指的是腳本），怎么獲得該腳本掛的物體呢，其實是有記錄的，gameObject就是腳本當前掛的物體。
下面講下本實驗的過程：
成品圖：
做的確實不好。。。
玩法：每按一次空格能出來一個飛碟，然后點擊鼠標去點它，點中了會消失，或者飛離一定距離也會消失。
代碼：
功能少所以代碼比較少。

小結：
- 我只是將自己學到的一點東西分享一下，可參考度不高，如果要參考建議還是看大神寫的博客，我還有很多很多要改要學習要改進的地方，希望自己后面能學得更好
（實訓+3d+現操+計組已經夠忙的了，每天都能看到深夜的月亮。。。）
