使用cocos2d-x开发各种编辑器

感觉cocos2d/x的各种编辑器还是挺丰富的，但由于都是免费的软件，其中有各种隐患，cocos2d/x在不断的更新，但如果相应的编辑器没更新的话，这软件就不能用了，或者有些软件的bug层出不穷，所以自己能动手开发相应的编辑器还是有必要的。一开始想用windows的GDI开发，后来再想了一下为啥不直接用cocos2d-x来开发呢，将cocos2d-x嵌入到MFC里，就可以将windows各种强大的控件跟cocos2d-x各种动画结合起来了。

原理很简单，cocos2d-x在windows上运行的时候其实也是依赖于窗口的，但那是一个顶层窗口，要稍微修改一下，将cocos2d-x运行在一个子窗口里，这样就能嵌入到编辑器里。

打开cocos2d-x的libcoco2d库里的platform/win32/CCEGLView.cpp，替换boolCCEGLView::Create()的代码：

bool bRet = false;    do    {        CC_BREAK_IF(m_hWnd);        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     = 0;                              // No Extra Window Data        wc.cbWndExtra     = 0;                                // 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) && 1410 != GetLastError());        // center window position        RECT rcDesktop;        GetWindowRect(GetDesktopWindow(), &rcDesktop);        WCHAR wszBuf[50] = {0};        MultiByteToWideChar(CP_UTF8, 0, m_szViewName, -1, 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            0, 0,                                                // Window Position            //TODO: Initializing width with a large value to avoid getting a wrong client area by 'GetClientRect' function.            1000,                                               // Window Width            1000,                                               // Window Height            NULL,                                                // No Parent Window            NULL,                                                // No Menu            hInstance,                                            // Instance            NULL );        CC_BREAK_IF(! m_hWnd);        bRet = initGL();if(!bRet) destroyGL();        CC_BREAK_IF(!bRet);        s_pMainWindow = this;        bRet = true;    } while (0);#if(_MSC_VER >= 1600)    m_bSupportTouch = CheckTouchSupport();    if(m_bSupportTouch){    m_bSupportTouch = (s_pfRegisterTouchWindowFunction(m_hWnd, 0) != 0);    }#endif /* #if(_MSC_VER >= 1600) */    return bRet;

替换为

bool bRet = false;    do    {        CC_BREAK_IF(m_hWnd);        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     = 0;                              // No Extra Window Data        wc.cbWndExtra     = 0;                                // 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   = NULL;                         //        wc.lpszClassName  = kWindowClassName;               // Set The Class Name        CC_BREAK_IF(! RegisterClass(&wc) && 1410 != GetLastError());        // center window position        RECT rcDesktop;        //GetWindowRect(GetDesktopWindow(), &rcDesktop);GetClientRect(mParentHwnd,&rcDesktop);        WCHAR wszBuf[50] = {0};        MultiByteToWideChar(CP_UTF8, 0, m_szViewName, -1, 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_CHILDWINDOW|WS_VISIBLE,        // Defined Window Style            0, 0,                                                // Window Position            //TODO: Initializing width with a large value to avoid getting a wrong client area by 'GetClientRect' function.            1000,                                               // Window Width            1000,                                               // Window Height            mParentHwnd,                                                // No Parent Window            NULL,                                                // No Menu            hInstance,                                            // Instance            NULL );        CC_BREAK_IF(! m_hWnd);        bRet = initGL();if(!bRet) destroyGL();        CC_BREAK_IF(!bRet);        s_pMainWindow = this;        bRet = true;    } while (0);#if(_MSC_VER >= 1600)    m_bSupportTouch = CheckTouchSupport();    if(m_bSupportTouch){    m_bSupportTouch = (s_pfRegisterTouchWindowFunction(m_hWnd, 0) != 0);    }#endif /* #if(_MSC_VER >= 1600) */    return bRet;

在libcocos2d项目下增加一个文件，里面存放MFC跟cocos2d-x交互的C函数。

extern "C"{CC_DLL bool M2InitializeApplication( HWND hwnd ){cocos2d::CCEGLView::SetParentHwnd(hwnd);// create the application instanceAppDelegate app;cocos2d::CCEGLView* eglView = cocos2d::CCEGLView::sharedOpenGLView();eglView->setFrameSize(480, 320);// The resolution of ipad3 is very large. In general, PC's resolution is smaller than it.// So we need to invoke 'setFrameZoomFactor'(only valid on desktop(win32, mac, linux)) to make the window smaller.//eglView->setFrameZoomFactor(0.4f);cocos2d::CCApplication::sharedApplication()->run();return true;}CC_DLL bool M2GameCleanUp(){cocos2d::CCDirector::sharedDirector()->end();cocos2d::CCEGLView* eglView = cocos2d::CCEGLView::sharedOpenGLView();eglView->Destroy();return true;}CC_DLL bool M2GameLoop( float interval ){cocos2d::CCDirector::sharedDirector()->mainLoop();return true;}}

后在MFC的对话框或View的初始化函数里增加如下代码，以绑定cocos2d的句柄并设置cocos2d视口的大小：

HWND hCocos = ::GetDlgItem(this->m_hWnd, IDC_PANEL);CRect rect;::GetWindowRect(hCocos, &rect);ScreenToClient(&rect);::MoveWindow(hCocos, rect.left, rect.top, 480, 320, TRUE);::M2InitializeApplication(hCocos);

增加一个定时器辅助cocos2d进行重绘：

SetTimer(1,16,NULL);

在OnTimer函数里刷新cocos2d-x:

::M2GameLoop(16);
