  • Python3+pygame实现的90坦克大战 代码完整 有演示效果

    我是一个典型的80后,年轻时玩过了特别多的游戏,所以这几天用Python3+pygame实现了一个另外小游戏”坦克大战“(其他的游戏,请翻阅我的博客)

    本实例代码量有些多,完整的版本在1000行左右(当然了如果再次优化的话 会减少一部分)

    分享出来,希望能帮助到大家,毕竟自己做教育行业做了这么多年,还是教育情怀的,哈哈哈哈哈

    一、显示效果

    二、代码

    下面代码用到了一些素材(游戏背景音乐、图片等等),可以到我的网站https://www.itprojects.cn/web/material/details.html?id=7下载,谢谢大家的支持

    完整代码如下(注意:为了方便下载以及编写更简单,没有采用多模块的方式,全部代码全部放到main.py文件中)
