如何用pygame编写一个简单小游戏（升级后的2048小游戏）
如何用pygame编写一个简单小游戏（升级后的2048小游戏）那当然是大大的不同那，今天教大家写的这款是有界面的小程序，单单是有界面的这一点就可以超前面那款了，更加富有趣味性的撒~来，我们来看看!慢慢来，木木子一直在等你们崛起~哈哈哈哈 ，呐~ 现在这篇文章的话是上次承诺的一个升级版本的2048小游戏。比之之前那款呢？有什么不同？
导语“嗨嗨嗨！别睡了，醒醒醒醒！该干活儿了~” by——顾木子吖！
“刚睡醒，大佬你有什么事儿吖？” by——全体成员！
上期给大家分享的超详细——简易版本的2048都吃透了没？咳咳咳......没吃透也没关系！
慢慢来，木木子一直在等你们崛起~哈哈哈哈 ，呐~ 现在这篇文章的话是上次承诺的一个升级版本的2048小游戏。
