cocos2dx 读取tilemap objectgroup 属性为空问题

我的版本是2.0rc  读取objectgroup 的属性的时候 出现了：http://www.cocos2d-x.org/boards/6/topics/13525?r=13704#message-13704 里面提到的问题

提问的楼主提出了 用tinyxml解决读取的问题 挺好的

这里转下他的代码：

if (pBuffer)

{

        //Load data

        ///////////////////////////////////////////////////////////////////////////////////////////////////

        tinyxml2::XMLDocument doc;

        doc.Parse((const char*)pBuffer);

tinyxml2::XMLElement* map = doc.FirstChildElement("map");

        if ( map )

{

            tinyxml2::XMLElement* objects = map->FirstChildElement("objectgroup");

            if ( objects )

    {

                tinyxml2::XMLElement* firstChild = objects->FirstChildElement();

                if ( firstChild )

        {

                    tinyxml2::XMLElement* nextChild = firstChild;

                    while ( nextChild != NULL )

            {

                        std::string elementName = nextChild->Name();

                        if ( elementName == std::string("object") )

                {

                            onEntityElement(nextChild, scene);

                        }

nextChild = nextChild->NextSiblingElement();

                    }

                }

            }

        }

        ///////////////////////////////////////////////////////////////////////////////////////////////////

    }

void MapLoader::onEntityElement(tinyxml2::XMLElement* object, cocos2d::CCLayer* scene) {

//Position and type

float x = object->FloatAttribute("x");

float y = object->FloatAttribute("y");



float width = object->FloatAttribute("width");

    float height = object->FloatAttribute("height");

//x = (x)-m_map->getMapSize().width*32;

    y = (y)+m_map>getMapSize().height*32;

CCPoint pos = ccp(x,y);

std::string type = object->Attribute("type");

//Attributes

    std::vector<SObjectParam> params;

    tinyxml2::XMLElement* props = object->FirstChildElement("properties");

    if ( props )

{

        tinyxml2::XMLElement* firstChild = props->FirstChildElement();

        if ( firstChild )

    {

            tinyxml2::XMLElement* nextChild = firstChild;

            while ( nextChild != NULL )

        {

                if ( std::string(nextChild->Name()) == std::string("property") )

            {

                    SObjectParam param;

                    param.m_name = nextChild->Attribute("name");

                    param.m_value = nextChild->Attribute("value");

                    params.push_back(param);

                }

nextChild = nextChild->NextSiblingElement();

            }

        }

    }

//Create entity

    GameObject* obj = GameObjectFactory::createObject(type, pos, params, width, height);

    if ( obj )

{

        m_map->addChild(obj);

    }

不过还是希望 2.0能解决读取xml objectgroup 属性为空的问题 因为 1.01读取是没有问题的
