【小游戏】用C++结合EasyX制作扫雷1
开头
这个程序使用了EasyX图形库，简单易用，可以画出丰富的图形和文字。
EasyX官网
可以看这篇文章入门：EasyX基础入门——这一篇就够啦_绿駬的博客-CSDN博客
官网有下载链接和文档，我使用的是VC++编译器，环境是Visual Studio 2022，注意在项目设置中把Unicode字符集改为多字节字符集
步骤
- 准备好图像文件，不同状态的格子我们就不自己画了（结尾提供）
- 引用头文件（graphics.h）
- 准备好全局变量（单个格子大小(单位：像素)，雷数常量，格子布局长宽(单位：格子)，窗口宽度，窗口高度）
- 定义一个格子对象
- [主函数]加载图像
- [主函数]初始化雷盘(layout二维数组)并随机布雷
- [主函数]死循环监测鼠标操作
- [主函数][死循环]监测点击到的格子，获取周围格子数并显示，判断输赢
