最近没啥事情可以去做，就去了解了一下pygame这个包。用这个包做了一个简单的小游戏。闲的蛋疼的小同学可以了解一下，哈。
代码路径一个可以控制小飞机投球和竹篮接球的小游戏 (github.com)
具体操作方式
- 按任意键进入游戏
- 游戏中按下esc退出游戏
- 上下左右控制无人机的行动
- enter键可以投球
- space可以停止运动
- a，d可以控制竹篮的左右运动
-
左上角则是记录得分与生命值
代码结构图
alien_invasion.py中是游戏的主函数，有四个类来支撑主函数中的四样东西，无人机（ship）篮球（bullet）鸟（bird）竹篮（bucket），将一些需要经常修改该参数放在settings里面，调用的函数放在game_functions中。
首先来说主函数alien_invasion.py里面放了三个函数run_game，begin_game，over_game。对应游戏主函数，游戏开始之前的选择页面，和游戏结束页面

先由run_game运行，进入begin_game，用一个死循环显示选择游戏模式页面ai_settings是所有设置的结构体。
