cocos2d-x 如何实现角色在地图中的不同高低台阶行走的路线控制

我要说的意思是这样的，角色从一个台阶跳向另一个台阶。两个台阶高低是不一样的。结果让角色停在另一个台阶上而不是掉下来！

void MapLayer::mapCreate(){    this->_allMap=CCTMXTiledMap::create("map/rosemap.tmx");this->_allMap->setScale(0.5);this->addChild(this->_allMap);this->_allMap->layerNamed("fangluoxia")->setVisible(true);//让防落下不可见CCTMXObjectGroup*  objGroup =this->_allMap->objectGroupNamed("pengzhuang");CCArray*  objArray = objGroup->getObjects();if( objArray&& objArray->count()>0){CCObject* pObj = NULL;    CCARRAY_FOREACH(objArray, pObj)    {    CCDictionary*  playerPointDic= (CCDictionary*)pObj; //将对象转化成字典，便于获取键值   float x = playerPointDic->valueForKey("x")->floatValue();    this->_y = playerPointDic->valueForKey("y")->floatValue();  }}}void MapLayer::jlmInRoad(float dt){if(((PmdInAllLayer*)this->getParent())->_jlmLayer->_isJlmCreate){CCSize mapTiledNum = this->_allMap->getMapSize();    CCSize tiledSize = this->_allMap->getTileSize();   CCPoint point1 =((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->getPosition();  int x =point1.x *2 / tiledSize.width;    int y =point1.y *2 / tiledSize.height;    /* Cocos2d-x的默认Y坐标是由下至上的，所以要做一个相减操作 */    y = mapTiledNum.height - y;    int tiledGid=_allMap->layerNamed("fangluoxia")->tileGIDAt(ccp(x,y));  if(tiledGid!=0)  {  CCDictionary* propertiesDict = _allMap->propertiesForGID(tiledGid);    /* 取得格子的zhezhao属性值 */    const CCString* prop = propertiesDict->valueForKey("flx");    /* 判断zhezhao属性是否为true,是的话，不让玩家移动 */    if(prop->m_sString.compare("true") == 0) {    //((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->setPosition(ccp(((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->getPosition().x,80)); //((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->_jumpDownHigh=90;//((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->setPosition(ccp(((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->getPosition().x+0.1*dt,100));((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->setPosition(ccp(((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->getPosition().x+0.1*dt,0.5*this->_y));  }    } else{((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->setPosition(ccp(((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->getPosition().x,((PmdInAllLayer*)this->getParent())->_jlmLayer->_jlmSprite->getPosition().y-100.0*dt));}}  }

基本上就是这样！
