帮我写一段MFC打地鼠代码

好的，请稍等，我为您生成一段MFC打地鼠代码：

#include <afxwin.h>
#include <time.h>

const int GAME_WIDTH = 500;
const int GAME_HEIGHT = 500;
const int TIMER_INTERVAL = 500;
const int HOLE_SIZE = 50;
const int HIT_THRESHOLD = 20;

class CGameWindow : public CFrameWnd {
public:
    CGameWindow() {
        Create(NULL, L"MFC打地鼠游戏", WS_OVERLAPPEDWINDOW, CRect(0, 0, 
            GAME_WIDTH, GAME_HEIGHT));
        srand(time(0));
        SetTimer(1, TIMER_INTERVAL, NULL);
    }

    afx_msg void OnPaint() {
        CPaintDC dc(this);
        for (int i = 0; i < m_holes.size(); i++) {
            CRect holeRect = GetHoleRect(m_holes[i]);
            if (m_holes[i].hit) {
                dc.FillSolidRect(holeRect, RGB(255, 0, 0));
            } else {
                dc.FillSolidRect(holeRect, RGB(127, 127, 127));
            }
        }
    }

    afx_msg void OnLButtonDown(UINT flags, CPoint point) {
        for (int i = 0; i < m_holes.size(); i++) {
            if (GetHoleRect(m_holes[i]).PtInRect(point)) {
                if (!m_holes[i].hit) {
                    m_holes[i].hit = true;
                    Invalidate();
                }
            }
        }
    }

    afx_msg void OnTimer(UINT_PTR timerID) {
        m_timerCount++;
        if (m_timerCount % 5 == 0) {
            GenerateNewHole();
        }
        for (int i = 0; i < m_holes.size(); i++) {
            if (m_holes[i].hit) {
                m_holes[i].hitCountdown--;
                if (m_holes[i].hitCountdown == 0) {
                    m_holes.erase(m_holes.begin() + i);
                    i--;
                }
            } else {
                m_holes[i].lifetime--;
                if (m_holes[i].lifetime == 0) {
                    m_holes.erase(m_holes.begin() + i);
                    i--;
                }
            }
        }
        Invalidate();
    }

    DECLARE_MESSAGE_MAP();

private:
    struct Hole {
        int x, y;
        bool hit;
        int hitCountdown;
        int lifetime;
    };

    std::vector<Hole> m_holes;
    int m_timerCount = 0;

    CRect GetHoleRect(Hole hole) {
        return CRect(hole.x - HOLE_SIZE / 2, hole.y - HOLE_SIZE / 2, 
            hole.x + HOLE_SIZE / 2, hole.y + HOLE_SIZE / 2);
    }

    void GenerateNewHole() {
        Hole newHole;
        newHole.x = rand() % (GAME_WIDTH - HOLE_SIZE) + HOLE_SIZE / 2;
        newHole.y = rand() % (GAME_HEIGHT - HOLE_SIZE) + HOLE_SIZE / 2;
        newHole.hit = false;
        newHole.hitCountdown = 3;
        newHole.lifetime = 10;
        m_holes.push_back(newHole);
    }
};

BEGIN_MESSAGE_MAP(CGameWindow, CFrameWnd)
    ON_WM_PAINT()
    ON_WM_LBUTTONDOWN()
    ON_WM_TIMER()
END_MESSAGE_MAP()

class CGameApp : public CWinApp {
public:
    virtual BOOL InitInstance() {
        CGameWindow* pMainWnd = new CGameWindow;
        m_pMainWnd = pMainWnd;
        pMainWnd->ShowWindow(m_nCmdShow);
        pMainWnd->UpdateWindow();
        return TRUE;
    }
};

CGameApp theApp;

这段代码实现一个简单的打地鼠游戏，当您单击地鼠，地鼠会变成红色，并在3秒钟后消失。游戏每隔0.5秒钟刷新一次画面，每隔5秒钟会生成一个新的地鼠出现在随机位置。请注意，这只是一个简单示例，您可能需要根据您的实际需求进行修改和扩展。
