python飛機大戰源碼，基于pygame的飛船大戰外星人游戲

作為一名熱愛玩游戲且正在學習Python的小白，自然對“做游戲”產生了濃厚的興趣。正好《Python從入門到實踐》一書中有一個游戲項目，自己便拿來邊學邊練手。
真正自己做游戲才明白開發游戲是一件多么難的事，但凡有一個方面考慮不周可能游戲就會產生bug，所以對游戲的那些狗策劃倒也有了些同情，，，
言歸正傳，下面是游戲的代碼，左右鍵移動，空格鍵射擊，諸君可以自己運行玩一玩。
整個游戲代碼主要由以下幾部分組成：

主函數gogo.py
飛船模塊Ship.py
外星人模塊alien.py
設置模塊Setting.py
包含大部分系統功能的模塊game_function.py
子彈模塊biu.py
負責存儲系統信息的模塊gamestate.py
按鈕模塊button.py
計分板模塊scoreboard.py
