DirectInput 模拟鼠标移动 C++ 代码示例

在 DirectInput 中模拟鼠标移动，需要使用 Windows API 函数来完成。以下是一个示例代码：

#include <windows.h>
#include <dinput.h>

// 定义鼠标移动的坐标
int x = 100;
int y = 100;

// 初始化 DirectInput
IDirectInput8* g_pDI = NULL;
IDirectInputDevice8* g_pMouse = NULL;
HRESULT InitDirectInput(HWND hWnd)
{
    HRESULT hr = DirectInput8Create(GetModuleHandle(NULL), DIRECTINPUT_VERSION, IID_IDirectInput8, (VOID**)&g_pDI, NULL);
    if (FAILED(hr)) return hr;
    hr = g_pDI->CreateDevice(GUID_SysMouse, &g_pMouse, NULL);
    if (FAILED(hr)) return hr;
    hr = g_pMouse->SetDataFormat(&c_dfDIMouse);
    if (FAILED(hr)) return hr;
    hr = g_pMouse->SetCooperativeLevel(hWnd, DISCL_EXCLUSIVE | DISCL_FOREGROUND);
    if (FAILED(hr)) return hr;
    hr = g_pMouse->Acquire();
    return hr;
}

// 释放 DirectInput
VOID CleanupDirectInput()
{
    if (g_pMouse)
    {
        g_pMouse->Unacquire();
        g_pMouse->Release();
        g_pMouse = NULL;
    }
    if (g_pDI)
    {
        g_pDI->Release();
        g_pDI = NULL;
    }
}

// 模拟鼠标移动
VOID SimulateMouseMove()
{
    DIMOUSESTATE mouseState;
    g_pMouse->GetDeviceState(sizeof(DIMOUSESTATE), &mouseState);
    x += mouseState.lX;
    y += mouseState.lY;
    SetCursorPos(x, y);
}

// 主函数
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
    // 创建窗口
    HWND hWnd = CreateWindow('MyWindowClass', 'MyWindow', WS_OVERLAPPEDWINDOW, 0, 0, 800, 600, NULL, NULL, hInstance, NULL);
    if (!hWnd) return 0;

    // 初始化 DirectInput
    if (FAILED(InitDirectInput(hWnd))) return 0;

    // 循环模拟鼠标移动
    while (TRUE)
    {
        SimulateMouseMove();
        Sleep(10);
    }

    // 释放 DirectInput
    CleanupDirectInput();

    return 0;
}

此代码将创建一个窗口，并使用 DirectInput 模拟鼠标移动。每 10 毫秒，它将获取鼠标的状态并根据鼠标的移动量更新鼠标的位置。然后，使用 Windows API 函数 SetCursorPos 将鼠标移动到新位置。请注意，此代码只是一个示例，实际应用中可能需要根据需要进行修改和扩展。
