python–飞机大战（课程设计）

项目名称：python飞机大战
编程语言：python
用到关键知识：pygame模块，python基础，os文件读写，以及面向对象思想方法！
实现功能：
1：飞机的移动，发射子弹，手雷，生命值，生命条
2：敌飞机有3种形态（小，中，大）不同的飞机大小不一样，生命值不一样，爆炸动画也不一样
3：背景音乐，子弹击中敌机会发生碰撞的爆炸动画和音效
4：随机产生补给（双射子弹和全屏炸弹）
5：难度逐渐增加（同一屏幕出现的飞机更多）
6：历史最高分纪录
项目分析：一个类文件（Main.py）,音乐音效共计10余种，照片素材共计30余张，代码共计800行左右！

代码如下：（一个类文件（800行代码））
