45°的地图对象层坐标不对

第一、tmx是支持对象层的，cocos2d只是解析
第二、既然你不显示那我自己获取坐标显示，看一眼代码解析的地方只考虑了正地图的坐标转换，45°根本不对
TMXObjectGroup* objectGroup = tmxMapInfo->getObjectGroups().back();

    // The value for "type" was blank or not a valid class name
    // Create an instance of TMXObjectInfo to store the object and its properties
    ValueMap dict;
    // Parse everything automatically
    const char* keys[] = {"name", "type", "width", "height", "gid", "id"};
    
    for (const auto& key : keys)
    {
        Value value = attributeDict[key];
        dict[key] = value;
    }

    // But X and Y since they need special treatment
    // X
    int x = attributeDict["x"].asInt();
    // Y
    int y = attributeDict["y"].asInt();
    
    Vec2 p(x + objectGroup->getPositionOffset().x, _mapSize.height * _tileSize.height - y  - objectGroup->getPositionOffset().y - attributeDict["height"].asInt());
    p = CC_POINT_PIXELS_TO_POINTS(p);
    dict["x"] = Value(p.x);
    dict["y"] = Value(p.y);
    
    int width = attributeDict["width"].asInt();
    int height = attributeDict["height"].asInt();
    Size s(width, height);
    s = CC_SIZE_PIXELS_TO_POINTS(s);
    dict["width"] = Value(s.width);
    dict["height"] = Value(s.height);

    // Add the object to the objectGroup
    objectGroup->getObjects().push_back(Value(dict));

    // The parent element is now "object"
    tmxMapInfo->setParentElement(TMXPropertyObject);
