简易版2D我的世界C++程序（有点BUG，但是可以玩！！！）

news 来源：原创 2025/4/27 8:23:07

1、按空格键来切换模式（挖掘模式和放置模式），一律用鼠标右键来操作！！！ 2、按数字1和2键来切换放置的方块（1是草，2是木），树叶不能放置！！！ 3、树木生成时可能有点BUG。 4、在操作时位置会有点偏移，请见谅。 5、地图默认大小为20*20，可以自己修改。（第15行和第16行） 6、~~本程序应该会持续更新~~

更新日志：

4月25日： 1、更新了新方块“石”，按数字3键切换（没错，树叶依然不可以放置） 2、石头会生成在草方块下面，会生成5层。 3、更改了地图的大小，为25*18。 4、操作偏移的bug依然存在（改了好几次，结果改的更离谱了）
