TiledLib for XNA throws ArgumentException on loading

Essentially, what I'm trying to do is to load/draw a map from a Tiled map using Nick Gravelyn's TiledLib. The map is saved in Tiled's XML format. However, when I try loading the map with the line

TiledLib.Map map = Content.Load<TiledLib.Map>("Maps/Map1");

it throws an ArgumentException. The whole thing renders like this in Tiled itself:

The map's XML source looks like this (not posted directly onto StackOverflow for obvious size reasons).

It worked at first (with a pretty simple map usin开发者_如何转开发g only one tileset) but when I edited it to include a bit more stuff then it suddenly started doing this. Could it be related to my usage of tile objects?

EDIT: I have been able to work out that using tile objects was not the culprit; this map structure still creates the same error.

you get an exception because you didn't name the objects in the map, this will cause ArgumentException in TiledLib. So, to solve this issue you need to go back to Tiled program, (re)edit this map, and select every object in the map and give it a name (not property but name) then export the map again and (re)import it into the game content. This should fix the problem.

BTW: I recommend using regular layer for collide check not object layer. Like this: Make small png file with a transparent red rectangle tile in it in the same map tile dimensions, add new layer to the map, name it CollideLayer, and in this CollideLayer put that red rectangle tile where you want to be a collide, and then in the game code you can check to see if the CollideLayer cell is empty or not. I find this is simpler.

I',m guessing, but looking at your XML structure in the section, there are a lot of repeats of

<tile gid="0"/>

in the data element. There is no documentation or schema definition on the structure of this file on the official site, and the content pipeline source is not available. Also, the demo of TileLib comes with that section as

<data encoding="base64" compression="gzip">

I'm not sure if you have an option to include encryption or not. But, the "gid" (global id ??) attribute cannot be the same for every tile defined if that is what it is. If I was writing this engine, I would have some way to readily identify each basic defined tile. Like a primary key on a data table. Which has to be unique. That would be the "gid" attribute for me.

Since the exception does not give any information (which is stupid - who deploys public libraries like that??), the argument exception is either that your "gid" attribute value is already defined, or that you're missing the encryption attributes which it expects in the pipeline importer or processor.
