cocos2d学习-动画缓存和动画创建

Animate* ActionTool::animationWithFrameName(const char*each_name, int iloops, float delay)
{
    SpriteFrame* frame = NULL;//声明一个图片帧
    Animation* animation = Animation::create();//创建一个动画
    int index = 1;//第几个帧
    do//循环遍历帧
    {
        String* name = String::createWithFormat("%s%d", each_name, index++);//第index++个图片帧名字
        frame = SpriteFrameCache::getInstance()->getSpriteFrameByName(name->getCString);//通过名字获取图片帧 
        if (frame == NULL)//判断帧是否为空
        {
            break;
        }
        animation->addSpriteFrame(frame);//把帧加入到动画中
    } while (true);
    animation->setDelayPerUnit(delay);//帧延时--时间间隔 
    animation->setRestoreOriginalFrame(true);//动画结束后返回到开始帧
    Animate* animate = Animate::create(animation);//创建动作
    return animate;
