黄金矿工

前一段时间用C++的EasyX的图形库做了一个黄金（weisuo）矿工小游戏。
这应该是在跨年之前写的，但是当时没有发文章。

关于可视化窗口开发

EasyX是一个C/C++的图形库，比较简单方便，适合新手上手学习开发思路。但是网上有人说它过于简单，不适合开发大型项目。
emm，说句实话，我觉得EazyX拿来学习一下思路练练手就OK了，不用过多的研究。
关于C/C++的多媒体库，学习软件开发可以看看QT库，游戏开发可以学习一下SDL2，OpenGL，SFML。
相关的教程可以上B站或者YouTube搜索，我后期也会更新一下放映室功能，放一些我觉得比较好的视频，可以参考。

正文

比较猥琐。

大概的界面就是这样，还有很多漏洞，欢迎大家帮我修一下（招募免费劳动力）。
代码我放在GitHub仓库了，可以直接下载。
因为这个项目只有一个文件，而且不是很长，所以我也直接放在下面。
因为很懒，而且编程习惯不好，所以没有写注释，后期有时间写一下，暂时需要自己理解一下。
