Pygame实战练习之炸弹人学院游戏

导语

在现在这个浮躁的年代：小编每次登陆王者荣耀，还有每次登陆刺激战场Z！

看着里面的聊天界面，各种代打、各种的找cp。小小编觉得，我们已经失去了玩游戏的初心。

接下来，小台将带领你们走回童年时光，一起领略我们当初玩4399的单纯与天真！

​

还记得小时候小台每到放学时刻，就会拉着只比我小半岁的小表妹，一块去亲戚家里玩电脑

每一次打开电脑做的第一件事情就是，打开浏览器，输入4399这四个数字，那个时候觉得hao123真是一个神奇的主页！

可以让我打开4399玩各种游戏qwq，尤其是Q版泡泡堂深得我心！

​

那今天就带大家回忆一下童年也做一款经典的炸弹人的小游戏！

正文

游戏规则还清楚哈， 我就不多做介绍了不清楚玩法的可以百度下下！

首先准备好相应的素材：【部分如下】
