pygame写推箱子200多关卡

hi大家好，我是直言的伪都鹧。今天我来给大家展示的pygame写的小游戏就是推箱子首先给大家讲一讲这类游戏的历史。

推箱子历史介绍

推箱子是非常经典的解谜游戏，源自日本，到现在已经接近40年的历史了。日本其实逻辑谜题一直比较流行，Sudoku，Nonogram之类的经典的谜题大都是在日本发展起来的，这要归功于谜题出版商Nikoli。

电脑解谜游戏方面，日本也比较领先，70年代末才出现了第一代个人电脑，而推箱子也是同一时代的作品。它是在在1981年由Hiroyuki Imabayashi（今林宏行）设计，英文名叫Sokoban（日文倉庫番，就是仓库工人），用BASIC语言编写，运行在PC-8801上，这是日本的第一代PC。

据传他当时并没有打算商业化，做出来只是给朋友玩。后来在一名软件发行公司的推销员建议下才开始商业化制作。他成立了Thinking Rabbit，自己担任社长，并发行了这个游戏。

最初版本只有20关，其中前10关是正常关卡，后面10关则是带有隐藏墙壁的变化关卡，因为后面不是纯逻辑谜题了，所以一般在讨论关卡数时认为初代只有10关。

两年后，也就是1984年，他们推出了2代，有50关，这也就是到现在为止很多作者模仿的经典版。

此后，Thinking Rabbit分别在1989年和1991年推出了Sokoban Perfect和Sokoban Revenge，各有306关，这些关卡合起来基本就是现在市面上各种推箱子游戏关卡的来源。

这四款游戏都是发布在日本NES产的个人电脑， Spectrum HoloByte在1988年才把这款游戏引入欧美，移植到了比较流行的IBM-PC，Apple II之类的平台上，是经典版的50关。在1990年，台湾大宇公司推出了仓库世家，正式将推箱子引入了中囯，此游戏一共250关。1995年，大宇又先后引进了Sokoban Perfect和Sokoban Revenge，游戏名分别叫仓库番：史上完整版和仓库番：玩家复仇版。Thinking Rabbit也是很长时间没有出什么新作，只是不断的推出沿用之前关卡的作品和授权移植，推箱子被移植到了十几个平台，包括GB，MD，PS等。但新关卡其实不多，大部分关卡也都是来自于Perfect和Revenge两作。
