本文分享的这些俄罗斯方块代码是我最近放假在家里自己写的，虽然以前有过看别人写的代码，但是那个游戏代码好像不是很全面，因为无法实现全部的方块和实现随机的产生任意方向的方块，现在也基本上是忘光了当时的代码，下面的这些代码是我最近写的，没有参考其他人的代码，真正写俄罗斯方块起来感觉真的是挺难的，关键是在于方块的旋转。当然下面的代码仅仅是一个框架，只能够实现大致上的功能，还不全面，贴出来和大家交流学习。
编译器是code：：block + MinGW ，感觉CB这个IDE真的是太强大，太棒了，下面的代码直接复制到VC里面运行应该不会出错，有个问题一直不知道怎么解决，就是更新客户区时窗口总是闪不知道有哪位达人能指点我一下。有的都是windows API写的，对windows编程还不是很懂，望大家多多留言，指点一下本人。
