Anyone know how to use TMX in libGDX?

Hi all, Im having real trouble getting use of my Object Layers in TMX files within my libGDX project. I can load the file and it draws the Tile Layers images, but I need to get the Y coordinate for each of the platforms I placed in the Tiled project.

Here is the TMX file:

<?xml version="1.0" encoding="UTF-8"?>
<map version="1.0" orientation="orthogonal" renderorder="right-up" width="20" height="5" tilewidth="256" tileheight="256" nextobjectid="47">
 <tileset firstgid="1" name="bg" tilewidth="256" tileheight="256" tilecount="12">
  <image source="../textures/bg.jpg" width="1024" height="768"/>
 </tileset>
 <tileset firstgid="13" name="platforms" tilewidth="256" tileheight="256" tilecount="2">
  <tile id="0">
   <image width="256" height="256" source="../textures/tiles-brown.png"/>
  </tile>
  <tile id="1">
   <image width="256" height="256" source="../textures/tiles-green.png"/>
  </tile>
 </tileset>
 <layer name="background" width="20" height="5">

  <object id="42" name="floorRect" type="rectie" gid="14" x="256" y="1280" width="256" height="256"/>
 </objectgroup>
</map>

And here is my libgdx Level class snippet (btw- I know this is completely wrong! It’s one of many things I’ve tried and I’m completely lost now):

platformRects = new Array();

    mapLayer1 = (TiledMapTileLayer)map.getLayers().get(1);
    objects = mapLayer1.getObjects();
    for (int i = 0; i < (mapLayer1.getWidth() / mapLayer1.getTileWidth()); i++){
        for (int n = 0; n < (mapLayer1.getHeight() / mapLayer1.getTileHeight()); n++){
            objects.getByType(rectie,platformRects);

        }

    }

The main thing I am stuck on is the calls and code I need to make to get the x coordinate from the TMX file and put them into an array so I can pass that info into the Platform class and then create all the blocks in the right place. I was told the getObjects() on the layer will do this but I have no clue how to go about it

Thanks for no help! :\

Well… you asked a question about implementiation details of a very specific library. Maybe you have a better chance to get a reply if you ask the community of that library.

Just in case any poor souls stumble across this thread with a similar issue. I have it solved on this forum here: http://www.badlogicgames.com/forum/viewtopic.php?f=11&t=21068

Basically the RectangleMapObject in libgdx doesn’t ‘see’ the objects placed with Tiled using the ‘Place Tile’ option within the Objects Layer, If I then manually draw rectangles using Tiled’s Rectangle Objects my code works a treat.

Peace :wink: … And btw, Tiled (/Bjorn and etc), thanks very very much for this helpful tool
