前言
这是我初中闲时使用C++ EGE库开发的一个小型扫雷游戏，高中时为了在学校大屏幕（触屏）游玩又适配了触屏操作；这个扫雷游戏异于传统扫雷游戏，我使用了区块技术动态生成地图来实现了无穷无尽的游戏体验。
机制
- 无限地图：采用9×9区块动态生成，当视口进入新区块时候，旧区块会卸载并保存到磁盘，新区块会立即生成（为什么是9×9大小可能是当时为了疫情网课方便摸鱼？？？）。
- 智能生成：难度会随着坐标的增大而增大。
- 分数系统：初始50分，标记地雷加分，踩雷和错误标记扣分（当然你也可以通过修改配置文件来让你的分数为9999999）。
玩法
- 左键点击：翻开格子，若踩雷-25分。
- 右键点击：标记地雷，标记正确+3分，错误-30分。
- 按下并拖拽：快速移动视口（左右键均可，属于一个小bug但是无伤大雅懒得改了）。
- A/W/S/D：精准移动视口。
备注
为了方便学习编程，源代码我与程序放在一起了，使用前记得解压到一个专门的文件夹去使用。
关于源代码，我使用的是EGE24.04版本，目前EGE最新版本是25.11，新版本在编译我的代码的时候会出现一些显示异常。
