我是靠谱客的博主殷勤玉米，最近开发中收集的这篇文章主要介绍C++实现俄罗斯方块，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

本文实例为大家分享了C++实现俄罗斯方块的具体代码，供大家参考，具体内容如下

工具：vc++2010,图库:EasyX

先看效果图片

纯手写，没有面向对象思想,看全部源码

分析项目：

1.必须要有欢迎界面
2.搭建合理的边界,就是游戏范围
3.逻辑1:先出现右上方的方块样式,等待一段时间,将右上方的样式在游戏区打印出
4.逻辑2,方块降落,要擦除原先印记,将1改为0
5.逻辑3,热键控制移动方向,暂停及变形,且不能移动出界,判断方块是否还能移动
6.逻辑4,方块凝固在下方不出界
7.逻辑5,最下面一行方块叠满了,消去它并把上面的行都下移(分两种情况),并且再次检查这一行
8.逻辑6,计算消除行数次数,统计分数,控制休眠时间长度
9.逻辑7,每次移动先判断是否能移动,默认结束程序,在合理游戏区返回false,结束界面
