Lua——模仿按键精灵

时间：2016.11.02

主要使用C导出库提供按键精灵功能库的模拟，Lua负责调用这些接口实现脚本功能

---

首先要模拟鼠标和按键功能需要用到下面两个函数:

// 模拟鼠标功能VOID mouse_event(    DWORD dwFlags,          // motion and click options    DWORD dx,               // horizontal position or change    DWORD dy,               // vertical position or change    DWORD dwData,           // wheel movement    ULONG_PTR dwExtraInfo   // application-defined information);// 模拟键盘功能VOID keybd_event(    BYTE bVk,             //虚拟按键码    BYTE bScan,           //定义该键的硬件扫描码    DWORD dwFlags,        //KEYEVENTF_KEYDOWN:0  KEYEVENTF_KEYUP    DWORD dwExtralnfo     //定义与击键相关的附加的32位值);   

主要是直接加载C的动态链接库，导出类似按键精灵里面使用的命令
Delay : 延时
MoveTo: 鼠标移动
LeftClick: 鼠标左键点击
LeftDClick: 鼠标左键双击
RigthClick: 鼠标右键点击
RightDClick: 鼠标右键双击
LeftDown: 鼠标左键按下
LeftUp: 鼠标左键抬起
RightDown: 鼠标右键按下
RightUp: 鼠标右键抬起

最后通过Lua文件来设置脚本：

MoveTo = package.loadlib( "VicAssist.dll", "MoveTo" )LeftClick = package.loadlib( "VicAssist.dll", "LeftClick" )Delay = package.loadlib( "VicAssist.dll", "Delay" )MoveTo( 34, 42 )Delay( 200 )LeftClick()

鼠标会移动到该位置然后点击一次
