//判断整列是否至少有一个静态刚体struct IsAllColBody: binary_function<GameElementData, int ,bool>{bool operator()( GameElementData &value, int body) const{if (value.m_pGameElement != NULL){if (value.m_pGameElement->m_iBodyCate == body)return true;}return false;}};

vector<GameElementData>::iterator itIsAllColBody=find_if(StageManager::getInstance()->m_arrvecGameElement[i].begin(),StageManager::getInstance()->m_arrvecGameElement[i].end(),bind2nd(IsAllColBody(),GameElement::BCBlock)); if (itIsAllColBody!=StageManager::getInstance()->m_arrvecGameElement[i].end())//如果整列有静态刚体，则步数清零{StageManager::getInstance()->m_arrvecGameElement[i][j].m_iLeftMoveStep = 0;StageManager::getInstance()->m_arrvecGameElement[i][j].m_iStep = 0;}else{if(i > 0)//如果整列没有静态刚体，则计算步数{StageManager::getInstance()->m_arrvecGameElement[i][j].m_iLeftMoveStep = StageManager::getInstance()->m_arrvecGameElement[i-1][j].m_iStep;StageManager::getInstance()->m_arrvecGameElement[i][j].m_iStep = StageManager::getInstance()->m_arrvecGameElement[i][j].m_iLeftMoveStep;}}
