效果:
是不是有那味儿了?文章来源:https://www.toymoban.com/news/detail-795500.html
- 显示AWSD,空格,Shift和左右键的按键情况以及左右键的CPS。 彩虹色轮廓,黑白填充。
- 具有任务栏图标,可以随时关闭
- 字体是Minecraft AE Pixel,如果你没有装(大概率),你可以换用其他好看的字体(在代码中修改即可)
由于是从一个更大的项目中提取的代码,所以可能会有一些不美观之处。
必要的gcc编译参数:-lgdi32
代码如下:文章来源地址https://www.toymoban.com/news/detail-795500.html
