这篇文章主要介绍了Python3+Pygame实现射击游戏完整代码,本文给大家介绍的非常详细,对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下

之前看到过很多人写的飞机大战,当然了之前我也写过多个版本,总体来说功能是实现了,但总感觉不够“炫”

今天浏览Python资料的时候,意外发现了这个很好的“射击”类游戏,看上去类似飞机大战,但更好玩

一、游戏特点

1. 运行非常流畅

2. 默认有3条命,每条命的HP可以增加(吃补品)也可以减少(被击中)

3. 有碰撞时的音效

4. 有碰撞时的爆炸效果

二、运行效果展示

三、完整代码

四、运行方式

如果想要运行本程序,流程如下

1. 下载上述代码 例如存储为xxxx.py

2. 下载素材(图片、声音等)https://www.itprojects.cn/197.html

3. 切换到安装有pygame模块的python虚拟环境(如果没有pygame可以pip install pygame安装)

4. 使用命令运行 python3 xxxx.py
