CCDirector导演类
1。访问和改变场景
2。应用核心loop
3. 绑定和访问窗口
4。处理自动回收对象
5。处理事件消息转发
6。初始化各种管理器

8.在平台窗口绘图和opengl之间转换坐标

熟悉windows开发的同学都清楚，这个是windows 消息循环，在消息循环中实现了FPS逻辑，以及消息分发，分发后会由windows窗口类定义的消息处理函数来完成，消息处理函数在哪里呢？
CCEGLView* pMainWnd = CCEGLView::sharedOpenGLView();
pMainWnd->centerWindow();
可见在CCEGLView定义了窗口和窗口处理，看下源代码：

// Redraw On Size, And Own DC For Window.
wc.style = CS_HREDRAW | CS_VREDRAW | CS_OWNDC; //窗口样式，如果你想让windows 上的窗口没有标题栏，改这里呀。
wc.lpfnWndProc = _WindowProc; // WndProc Handles Messages 这个就是windows平台的消息处理函数，让我们下面看看_WindowProc源代码
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.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()); //注册窗口类
// center window position
RECT rcDesktop;
GetWindowRect(GetDesktopWindow(), &rcDesktop);
WCHAR wszBuf[50] = {0};
MultiByteToWideChar(CP_UTF8, 0, m_szViewName, -1, wszBuf, sizeof(wszBuf));
// create window 创建窗口
m_hWnd = CreateWindowEx(
WS_EX_APPWINDOW | WS_EX_WINDOWEDGE, // Extended Style For The Window

1，Cocos2dxActivity必定是核心
2，Coco2d-x的引擎就是在hellocpp.so中集成的，并且这里一定跟Cocos2dxActivity有者千丝万屡的联系，元方，你认为呢？
