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))
