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

7。处理在各Node的计划任务执行

8.在平台窗口绘图和opengl之间转换坐标

以下是CCDirector::init方法

bool CCDirector::init(void)
{
    CCLOG("cocos2d: %s", cocos2dVersion());

    // scenes 场景相关
    m_pRunningScene = NULL;
    m_pNextScene = NULL;

m_pNotificationNode = NULL;

    m_dOldAnimationInterval = m_dAnimationInterval = 1.0 / kDefaultFPS;
    m_pobScenesStack = new CCArray();
    m_pobScenesStack->init();

// Set default projection (3D)
m_eProjection = kCCDirectorProjectionDefault;

// projection delegate if "Custom" projection is used
m_pProjectionDelegate = NULL;

    // FPS 相关
    m_fAccumDt = 0.0f;
    m_fFrameRate = 0.0f;
    m_pFPSLabel = NULL;
    m_pSPFLabel = NULL;
    m_pDrawsLabel = NULL;
    m_bDisplayStats = false;
    m_uTotalFrames = m_uFrames = 0;
    m_pszFPS = new char[10];
    m_pLastUpdate = new struct cc_timeval();

    // paused ? 暂停
    m_bPaused = false;

    // purge ?
    m_bPurgeDirecotorInNextLoop = false;

m_obWinSizeInPixels = m_obWinSizeInPoints = CCSizeZero;

m_pobOpenGLView = NULL;

m_fContentScaleFactor = 1.0f;
m_bIsContentScaleSupported = false;

    // scheduler 计划任务
    m_pScheduler = new CCScheduler();
    // action manager 动作管理器
    m_pActionManager = new CCActionManager();
    m_pScheduler->scheduleUpdateForTarget(m_pActionManager, kCCPrioritySystem, false);
    // touchDispatcher 触摸消息分发器
    m_pTouchDispatcher = new CCTouchDispatcher();
    m_pTouchDispatcher->init();

// KeypadDispatcher 按键消息分发器
m_pKeypadDispatcher = new CCKeypadDispatcher();

// Accelerometer 重力加速器
m_pAccelerometer = new CCAccelerometer();

// create autorelease pool 对象自动释放池管理器
CCPoolManager::sharedPoolManager()->push();

return true;
