如何在Directx游戏中模拟鼠标点击

Question

我有一个用Directx编写的游戏（不是我的mmo游戏）。 游戏窗口未激活（未最小化，只是在其他窗口后面，但如果可能，也可以最小化）。

我想模拟鼠标单击x，y位置。 当我在游戏中单击时，Spy ++不会在消息中显示任何内容。

现在，我只是这样做：

private void start_Click(object sender, EventArgs e)
    {
        IntPtr ActualWindow = GetActiveWindow();

        ShowWindow(hWnd, ShowWindowCommands.Restore); //show game window
        Thread.Sleep(50);                             //a little slow down
        ClickOnPoint(hWnd, new Point(692, 87));       //click on x,y
        Thread.Sleep(50);                             //again a little slow down
        ShowWindow(hWnd, ShowWindowCommands.Minimize);//minimize game window
        ShowWindow(ActualWindow, ShowWindowCommands.Restore);//restore last active window
//sleep is needed for click, if i will do it too fast game will not detect the click
    }

private void ClickOnPoint(IntPtr wndHandle, Point clientPoint)
    {
        POINT oldPoint;
        GetCursorPos(out oldPoint);

        ClientToScreen(wndHandle, ref clientPoint);

        /// set cursor on coords, and press mouse
        SetCursorPos(clientPoint.X, clientPoint.Y);
        mouse_event(0x00000002, 0, 0, 0, UIntPtr.Zero); /// left mouse button down
        Thread.Sleep(18);
        mouse_event(0x00000004, 0, 0, 0, UIntPtr.Zero); /// left mouse button up
        Thread.Sleep(15);

        /// return mouse 
        SetCursorPos(oldPoint.X, oldPoint.Y);
    }

这是还原游戏窗口上的点击并最小化游戏窗口。

它的工作原理很好，但是当我不移动鼠标时...

我搜索其他东西。 我想单击鼠标而不真正移动它。 在游戏中甚至有可能吗？ 我没有要单击的按钮的手柄，因为它是游戏...

PS对不起，我的英语。

Answer 1

我的一些用于在非活动窗口上模拟鼠标单击的代码如下所示：

[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool PostMessage(int hWnd, uint Msg, int wParam, int lParam);

// int MouseX
// int MouseY
// public static readonly uint WM_LBUTTONUP = 0x202;
// public static readonly uint WM_LBUTTONDOWN = 0x201;

int lparam = MouseX & 0xFFFF | (MouseY & 0xFFFF) << 16;
int wparam = 0;
PostMessage(windowHandle, WM_LBUTTONDOWN, wparam, lparam);      
Thread.Sleep(10);  
PostMessage(windowHandle, WM_LBUTTONUP, wparam, lparam);

您可以尝试使用Sendiput。 这是文档： https : //msdn.microsoft.com/zh-cn/library/windows/desktop/ms646310(v=vs.85).aspx

这是我的示例：

包括：

    #include <stdio.h>
    #include <cstdlib>
    #include <windows.h>
    #include <winuser.h>
    #include <conio.h>

    INPUT input;
    int x = 889;
    int y = 451;

`// Mouse click up
    input.type = INPUT_MOUSE;
    input.mi.mouseData = 0;
    input.mi.dx = x * float(65536 / GetSystemMetrics(SM_CXSCREEN)); //x being coord in pixels
    input.mi.dy = y * float(65536 / GetSystemMetrics(SM_CYSCREEN)); //y being coord in pixels
    input.mi.dwFlags = (MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTDOWN);
    input.mi.time = 0;
    SendInput(1, &input, sizeof(input));`
`   
//Mouse click down
    input.type = INPUT_MOUSE;
    input.mi.mouseData = 0;
    input.mi.dx = x * float(65536 / GetSystemMetrics(SM_CXSCREEN)); //x being coord in pixels
    input.mi.dy = y * float(65536 / GetSystemMetrics(SM_CYSCREEN)); //y being coord in pixels
    input.mi.dwFlags = (MOUSEEVENTF_ABSOLUTE | MOUSEEVENTF_LEFTUP);
    input.mi.time = 0;
    SendInput(1, &input, sizeof(input));`

And You can do something like this to make sure you are in the focused window:

    HWND hWnd = ::FindWindowEx(0, 0, "YourGame - Use Spy++", 0);

    DWORD dwThreadID = GetWindowThreadProcessId(hWnd, NULL);
    AttachThreadInput(dwThreadID, GetCurrentThreadId(), true);

    SetForegroundWindow(hWnd);
    SetActiveWindow(hWnd);
    SetFocus(hWnd);

    AttachThreadInput(GetWindowThreadProcessId(GetForegroundWindow(), NULL),GetCurrentThreadId(), TRUE);
