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。
