!cocos2d 重复添加action事件

当点击的时候，如果不是按照开始点击计算的，那么持续点击会导致不会变大。

void Piece::setActived(bool active)
{

        _actived = active;
        CCAction *scale;
        if (_actived)
        {
            scale = CCScaleTo::create(0.2, 1.2);
        }
        else
        {
            scale = CCScaleTo::create(0.2, 1);
        }
        this->runAction(scale);

}

void Piece::setActived(bool active)
{
    if(_actived==active)
    {
        return ;
    }
    else
    {
        _actived = active;
        CCAction *scale;
        if (_actived)
        {
            scale = CCScaleTo::create(0.2, 1.2);
        }
        else
        {
            scale = CCScaleTo::create(0.2, 1);
        }
        this->runAction(scale);
    }
}
