可以通过继承Animate类获得里面的nextFrame变量来知道当前播放到了第几帧:

class MAnimate:public cocos2d::Animate
{
public:
    /**当前播放到第几帧*/
    int currentFrame = -1;
public:
    static MAnimate* create(Animation *animation);
    virtual void update(float t);

};

MAnimate* MAnimate::create(Animation *animation)
{
    MAnimate *animate = new MAnimate();
    animate->initWithAnimation(animation);
    animate->autorelease();

    return animate;
}
void MAnimate::update(float t)
{
    Animate::update(t);
    if (this->_nextFrame != this->currentFrame + 1){
        this->currentFrame = this->_nextFrame - 1;
        //log("currentFrame:%d", this->currentFrame);
    }
}

十分详细介绍的

最后,我来解答一下CCAnimationFrame类中的成员变量m_fDelayUnits的。这个变量其实是无用的!!!!

一、帧动画
你可以通过一系列图片文件,像如下这样,创建一个动画:
[cpp]  
CCAnimation *animation = CCAnimation::create();  
//从本地文件系统中加载图片文件到CCSpriteFrame中区,然后添加到CCAnimation中  
for (int i = 1; i < 15; i++)  
{  
    char szImageFileName[128] = {0};  
    sprintf(szImageFileName, "Images/grossini_dance_%02d.png", i);  
    animation->addSpriteFrameWithFileName(szImageFileName);    
}  
animation->setDelayPerUnit(2.8f / 14.0f); // 这个动画包含14帧,将会持续2.8秒.  
animation->setRestoreOriginalFrame(true); // 14帧播放完之后返回到第一帧  
  
CCAnimate *action = CCAnimate::create(animation);  
sprite->runAction(action);  // 运行精灵对象
