Cocos2d-X 2.2嵌入MFC的子窗口

1.在cocos2dx目录下创建基于对话框的MFC工程，对话框中间放一个Picture控件

2.添加cocos2dx的相关头文件包含路径、库包含路径和依赖项，可以参考其他cocos工程设置

3.选中Picture控件后右键单击，在弹出菜单中找到“添加变量”。为Picture控件生成一个控件变量。这里命名为m_cocosWin，并点击完成

4.右击工程添加MFC类，类名里输入“CCocos2dXWin”，并选择基类CWnd。把上面的m_cocosWin变量类型改为CCocoWin 然后点击“完成”并做如下修改。

4.1头文件添加变量和函数

    //是否已经初始化

    BOOL                m_bInitCocos2dX;

    //创建Cocos2dX窗口

    BOOL        CreateCocos2dXWindow();

4.2 cpp添加COCOS的头文件，并加入一个全局变量

#include "AppDelegate.h"

#include "cocos2d.h"

USING_NS_CC;

AppDelegate CocoApp;

4.3函数实现

//创建Cocos2dX窗口

BOOL CCocoWin::CreateCocos2dXWindow()

{

    //新建一个CRect变量获取窗口的客户区大小

    CRect    tClientRect;

    GetClientRect(&tClientRect);

    //取得使用的OpenGL视窗

    CCEGLView* eglView = CCEGLView::sharedOpenGLView(false,GetSafeHwnd());

    //指定客户区大小。

    eglView->setFrameSize(tClientRect.Width(),tClientRect.Height());

    //调用程序的运行函数，增加参数bool型变量控制是否进行消息循环。因为MFC控件本身有自已的消息响应处理。如果不改动的话，这里就会进入死循环。

    cocos2d::CCApplication::sharedApplication()->run();

    //这里将变量设置为TRUE

    m_bInitCocos2dX = TRUE;

    SetTimer(,,NULL);

    return TRUE;

}

4.4在CCocoToolDlg的OnInitDialog（）方法中调用 CreateCocos2dXWindow()

m_cocosWin.CreateCocos2dXWindow();

5.利用类视图为CCocoWin添加如下方法

代码实现如下：

void CCocoWin::OnTimer(UINT_PTR nIDEvent)

{

    //我们写一个renderWorld函数代表Cocos2d-x的世界渲染

    cocos2d::CCApplication::sharedApplication()->renderWorld();

    CWnd::OnTimer(nIDEvent);

}

void CCocoWin::OnDestroy()

{

    //在Cocos2d-x的引擎文件CCEGLView_win32.cpp中CCEGLView::release()会再次发送调用DestroyWindow，所以这里用变量m_bInitCocos2dX做下判断，避免二次销毁

    if(TRUE == m_bInitCocos2dX)

    {

        //退出将m_bInitCocos2dX设为FALSE

        m_bInitCocos2dX = FALSE;

        //释放定时器资源

        KillTimer();

        //调用显示设备单件实例对象的end函数

        CCDirector::sharedDirector()->end();

        //处理一次下一帧，必须调用.

        CCDirector::sharedDirector()->mainLoop();

        CWnd::OnDestroy();

    }

}

void CCocoWin::OnSize(UINT nType, int cx, int cy)

{

    CWnd::OnSize(nType, cx, cy);

    // TODO: 在此处添加消息处理程序代码

    if(TRUE == m_bInitCocos2dX)

    {

        CRect   tClientRect;

        GetClientRect(&tClientRect);

        //重新设置窗口大小及投影矩阵

        CCEGLView::sharedOpenGLView()->resize(tClientRect.Width(),tClientRect.Height());

        CCDirector::sharedDirector()->reshapeProjection(CCSizeMake(tClientRect.Width(),tClientRect.Height()));  

    }

}

6.CCEGLView做如下修改

头文件

    virtual bool Create(bool bCreateWin=true,HWND hWnd=NULL);

public:

    bool m_bIsSelfCreWin;//是否cocos自己创建了窗口

static CCEGLView* sharedOpenGLView(bool bCreateWin=true,HWND hWnd=NULL);//bCreateWin是否自己创建窗口,hWnd已有的MFC窗口句柄

cpp

void CCEGLView::centerWindow()

{

    if (! m_hWnd||!m_bIsSelfCreWin)

    {

        return;

    }

....

}

bool CCEGLView::Create(bool bCreateWin,HWND hWnd)

{

    bool bRet = false;

    do

    {

        CC_BREAK_IF(m_hWnd);

        m_bIsSelfCreWin=bCreateWin;

        if (bCreateWin)

        {

            HINSTANCE hInstance = GetModuleHandle( NULL );

            WNDCLASS  wc;        // Windows Class Structure

            // Redraw On Size, And Own DC For Window.

            wc.style          = CS_HREDRAW | CS_VREDRAW | CS_OWNDC;

            wc.lpfnWndProc    = _WindowProc;                    // WndProc Handles Messages

            wc.cbClsExtra     = ;                              // No Extra Window Data

            wc.cbWndExtra     = ;                                // No Extra Window Data

            wc.hInstance      = hInstance;                        // Set The Instance

            wc.hIcon          = LoadIcon( NULL, IDI_WINLOGO );    // Load The Default Icon

            wc.hCursor        = LoadCursor( NULL, IDC_ARROW );    // Load The Arrow Pointer

            wc.hbrBackground  = NULL;                           // No Background Required For GL

            wc.lpszMenuName   = m_menu;                         //

            wc.lpszClassName  = kWindowClassName;               // Set The Class Name

            CC_BREAK_IF(! RegisterClass(&wc) &&  != GetLastError());

            // center window position

            RECT rcDesktop;

            GetWindowRect(GetDesktopWindow(), &rcDesktop);

            WCHAR wszBuf[] = {};

            MultiByteToWideChar(CP_UTF8, , m_szViewName, -, wszBuf, sizeof(wszBuf));

            // create window

            m_hWnd = CreateWindowEx(

                WS_EX_APPWINDOW | WS_EX_WINDOWEDGE,    // Extended Style For The Window

                kWindowClassName,                                    // Class Name

                wszBuf,                                                // Window Title

                WS_CAPTION | WS_POPUPWINDOW | WS_MINIMIZEBOX,        // Defined Window Style

                , ,                                                // Window Position

                //TODO: Initializing width with a large value to avoid getting a wrong client area by 'GetClientRect' function.

                ,                                               // Window Width

                ,                                               // Window Height

                NULL,                                                // No Parent Window

                NULL,                                                // No Menu

                hInstance,                                            // Instance

                NULL );

        }else

        {

            m_hWnd=hWnd;

        }

        CC_BREAK_IF(! m_hWnd);

        bRet = initGL();

        if(!bRet) destroyGL();

        CC_BREAK_IF(!bRet);

        s_pMainWindow = this;

        bRet = true;

    } while ();

#if(_MSC_VER >= 1600)

    m_bSupportTouch = CheckTouchSupport();

    if(m_bSupportTouch)

    {

        m_bSupportTouch = (s_pfRegisterTouchWindowFunction(m_hWnd, ) != );

    }

#endif /* #if(_MSC_VER >= 1600) */

    return bRet;

}

CCEGLView* CCEGLView::sharedOpenGLView(bool bCreateWin,HWND hWnd)

{

    if (s_pEglView == NULL)

    {

        s_pEglView = new CCEGLView();

        if(!s_pEglView->Create(bCreateWin,hWnd))

        {

            delete s_pEglView;

            s_pEglView = NULL;

        }

    }

    return s_pEglView;

}

7.CCEGLView做如下修改

头文件添加方法

    //帧循环调用渲染

    virtual bool renderWorld();

cpp

bool CCApplication::renderWorld()

{

    static LARGE_INTEGER nFreq;

    static LARGE_INTEGER nLast;

    static LARGE_INTEGER nNow;

    static bool sbinit=true;

    //只执行一次

    if (sbinit)

    {

        QueryPerformanceFrequency(&nFreq);

        QueryPerformanceCounter(&nLast);

        sbinit=false;

    }

    // Get current time tick.

    QueryPerformanceCounter(&nNow);

    // If it's the time to draw next frame, draw it, else sleep a while.

    if (nNow.QuadPart - nLast.QuadPart > m_nAnimationInterval.QuadPart)

    {

        nLast.QuadPart = nNow.QuadPart;

        CCDirector::sharedDirector()->mainLoop();

        return true;

    }

    return false;

}

int CCApplication::run()

{

    PVRFrameEnableControlWindow(false);

    // Main message loop:

    MSG msg;

    LARGE_INTEGER nFreq;

    LARGE_INTEGER nLast;

    LARGE_INTEGER nNow;

    QueryPerformanceFrequency(&nFreq);

    QueryPerformanceCounter(&nLast);

    // Initialize instance and cocos2d.

    if (!applicationDidFinishLaunching())

    {

        return ;

    }

    CCEGLView* pMainWnd = CCEGLView::sharedOpenGLView();

    //pMainWnd->centerWindow();

    ShowWindow(pMainWnd->getHWnd(), SW_SHOW);

    //cocos自己创建的窗口才要循环处理消息

    bool bloop=CCEGLView::sharedOpenGLView()->m_bIsSelfCreWin;

    if (bloop)

    {

        while ()

        {

            if (! PeekMessage(&msg, NULL, , , PM_REMOVE))

            {

                // Get current time tick.

                QueryPerformanceCounter(&nNow);

                // If it's the time to draw next frame, draw it, else sleep a while.

                if (nNow.QuadPart - nLast.QuadPart > m_nAnimationInterval.QuadPart)

                {

                    nLast.QuadPart = nNow.QuadPart;

                    CCDirector::sharedDirector()->mainLoop();

                }

                else

                {

                    Sleep();

                }

                continue;

            }

            if (WM_QUIT == msg.message)

            {

                // Quit message loop.

                break;

            }

            // Deal with windows message.

            if (! m_hAccelTable || ! TranslateAccelerator(msg.hwnd, m_hAccelTable, &msg))

            {

                TranslateMessage(&msg);

                DispatchMessage(&msg);

            }

        }

        return (int) msg.wParam;

    }

    return ;

}

8.新建个Classes文件夹，并把AppDelegate两个文件复制过去，在VS中右击包含到工程里

9.把工程的工作目录指向Resources文件夹，可以是以前的COCOS工程的Resources目录

如果出现类似 error LNK2005: "void * __cdecl operator new(unsigned int)的错误，参考

http://m.blog.csdn.net/blog/dotphoenix/13511863

运行效果：

具体修改的思路不做详细说明，具体请参考
