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:
enter image description here

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 using 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.
