Cocos2d-x 帧动画

CCAnimation 就是一系列的图片组成一个动画序列，然后设置下每帧的播放时长。

CCAnimate 是一个动作，Action, 可以由CCAnimation创建，然后Sprite执行runAction.

 CCAnimation* animation = CCAnimation::create();
    for( int i=1;i<15;i++)
    {
        char szName[100] = {0};
        sprintf(szName, "Images/grossini_dance_%02d.png", i);
        animation->addSpriteFrameWithFileName(szName);
    }
    // should last 2.8 seconds. And there are 14 frames.
    animation->setDelayPerUnit(2.8f / 14.0f);
    animation->setRestoreOriginalFrame(true);

    CCAnimate* action = CCAnimate::create(animation);
    m_grossini->runAction(CCSequence::create(action, action->reverse(), NULL));
