游戏程序的操作不外乎两种——键盘输入控制和鼠标输入控制,几乎所有游戏中都使用鼠标来改变角色的位置和方向,本文主要是讲述如何使用C#调用Windows API函数实现鼠标模拟操作的功能.首先通过结合FindWindow和FindWindowEx寻找到窗体的按钮,在通过SetCursorPos或mouse_event函数操作鼠标,同时涉及到通过spy++工具获取窗体消息的信息.
鼠标自动点击按钮和查看鼠标运行轨迹:
首先创建一个C#工程,设计的窗体如下图所示,同时添加Timer时间器控件:
然后添加的如下代码,即可实现鼠标模拟技术及自动操作鼠标:
using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Windows.Forms;//引用新命名空间using System.Runtime.InteropServices; //StructLayout
namespace MouseAction{ public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
//结构体布局 本机位置
[StructLayout(LayoutKind.Sequential)]
struct NativeRECT
{
public int left;
public int top;
public int right;
public int bottom;
}
//将枚举作为位域处理
[Flags]
enum MouseEventFlag : uint //设置鼠标动作的键值
{
Move = 0x0001, //发生移动
LeftDown = 0x0002, //鼠标按下左键
LeftUp = 0x0004, //鼠标松开左键
RightDown = 0x0008, //鼠标按下右键
RightUp = 0x0010, //鼠标松开右键
MiddleDown = 0x0020, //鼠标按下中键
MiddleUp = 0x0040, //鼠标松开中键
XDown = 0x0080,
XUp = 0x0100,
Wheel = 0x0800, //鼠标轮被移动
VirtualDesk = 0x4000, //虚拟桌面
Absolute = 0x8000
}
//设置鼠标位置
[DllImport("user32.dll")]
static extern bool SetCursorPos(int X, int Y);
//设置鼠标按键和动作
[DllImport("user32.dll")]
static extern void mouse_event(MouseEventFlag flags, int dx, int dy,
uint data, UIntPtr extraInfo); //UIntPtr指针多句柄类型
[DllImport("user32.dll")]
static extern IntPtr FindWindow(string strClass, string strWindow);
//该函数获取一个窗口句柄,该窗口雷鸣和窗口名与给定字符串匹配 hwnParent=Null从桌面窗口查找
[DllImport("user32.dll")]
static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter,
string strClass, string strWindow);
[DllImport("user32.dll")]
static extern bool GetWindowRect(HandleRef hwnd, out NativeRECT rect);
//定义变量
const int AnimationCount = 80;
private Point endPosition;
private int count;
private void button1_Click(object sender, EventArgs e)
{
NativeRECT rect;
//获取主窗体句柄
IntPtr ptrTaskbar = FindWindow("WindowsForms10.Window.8.app.0.2bf8098_r11_ad1", null);
if (ptrTaskbar == IntPtr.Zero)
{
MessageBox.Show("No windows found!");
return;
}
//获取窗体中"button1"按钮
IntPtr ptrStartBtn = FindWindowEx(ptrTaskbar, IntPtr.Zero, null, "button1");
if (ptrStartBtn == IntPtr.Zero)
{
MessageBox.Show("No button found!");
return;
}
//获取窗体大小
GetWindowRect(new HandleRef(this, ptrStartBtn), out rect);
endPosition.X = (rect.left + rect.right) / 2;
endPosition.Y = (rect.top + rect.bottom) / 2;
//判断点击按钮
if (checkBox1.Checked)
{
//选择"查看鼠标运行的轨迹"
this.count = AnimationCount;
movementTimer.Start();
}
else
{
SetCursorPos(endPosition.X, endPosition.Y);
mouse_event(MouseEventFlag.LeftDown, 0, 0, 0, UIntPtr.Zero);
mouse_event(MouseEventFlag.LeftUp, 0, 0, 0, UIntPtr.Zero);
textBox1.Text = String.Format("{0},{1}", MousePosition.X, MousePosition.Y);
}
}
//Tick:定时器,每当经过多少时间发生函数
private void movementTimer_Tick(object sender, EventArgs e)
{
int stepx = (endPosition.X - MousePosition.X) / count;
int stepy = (endPosition.Y - MousePosition.Y) / count;
count--;
if (count == 0)
{
movementTimer.Stop();
mouse_event(MouseEventFlag.LeftDown, 0, 0, 0, UIntPtr.Zero);
mouse_event(MouseEventFlag.LeftUp, 0, 0, 0, UIntPtr.Zero);
}
textBox1.Text = String.Format("{0},{1}", MousePosition.X, MousePosition.Y);
mouse_event(MouseEventFlag.Move, stepx, stepy, 0, UIntPtr.Zero);
}
}
}同时自定义一个对话框,增加一个button按钮,其运行结果如下图所示:
