python 学习之尝试飞机大战游戏编程

大概思路

1. 开始界面
   鼠标点击特定区域，开始游戏

2. 游戏界面
   其中分为：
   计分，玩家生命值，玩家飞机，敌方飞机，发射子弹
   其中需要存储玩家飞机位置，判定按键输入（上下左右，a键发射子弹），随机函数，生成敌机位置，子弹命中判定，击中音效以及敌机，子弹运动轨迹函数。

3. 结束界面
   显示game over，并按键重新开始游戏

以下为代码

其中需要有敌机，玩家飞机，子弹，爆炸特效，开始方块按钮的贴图，以及爆炸音效! 我直接采用的网上搜索，ps处理的方法，但是在处理图片时，jpg格式一般会自带背景图，如果采用png格式读取，仍然会带有背景颜色，这里的问题尚未完全解决，需要更深层次的学习。
