It’s all Ms-Pl so you can extend it, re-release it, blog it, or do whatever you want with it.

That’s probably a good fix there. The property of TmxProcessor was sort of an afterthought for me. I tend to just keep the tile images with the maps.

This is pretty neat. I’ve been playing with it for the last couple of days, and I like it. Is it alright if I do a blog post expanding about this on my site? (I’m using reflection to automatically create game objects based on the stuff in the MapObject layers.)

I had a bit of a problem with the paths. I setup my folders just like you did in the example, but then Tiled couldn’t find the png file, since it was looking in the same folder. If I fix that, Tiled uses a relative path like “../TileSets/Tiles.png” which confuses Path.Combine in the TmxProcessor. So I changed that bit to this:

Path.Combine(TileSetDirectory, Path.GetFileName(tileSet.Image))

sorry, I jsut noticed it actually seems to work, collisionlayer is not null, but contains my single object…yeeesss

Nick, thanks for the reply, but I still don’t quite understand. Would you mind to maybe write one or two lines of code that would show me how to do it?
I have a lyer named “Collision” where I have all my collision rectangles.

I have two variables, one Layer object “layer” and one MapObjectLayer “Collisionlayer”.

now i do in Loadcontent, just after loading the map:

layer = map.GetLayer(“Collision”);
collisionLayer = (MapObjectLayer)layer;

But when I insert a breakpoint in this line, collisionlayer is null? What am I doing wrong? I guess I have not understood this casting somehow. Can you please help?

@Rabid: Download the project again. When I first uploaded it had that bug, but I fixed it and reuploaded it. Or you can fix it yourself. Just make sure line 51 of MapContent.cs looks like this:

foreach (XmlNode layerNode in document.SelectNodes(“map/layer|map/objectgroup”))

I had an error in my query string in the first upload.

@Michael: You need to add the content project and library project to your solution. Then add a reference on your game to the library and a reference on the content to the content project. The demo has this set up so look at the project references in there if you’re confused.

@Andi: You can get a named layer from the Map.GetLayer method. Then cast that to a MapObjectLayer which lets you use the GetObject method to get an object by name or you can simply enumerate the Objects collection.

May have found a bug or I am not doing something right. I added a object layer to my map and from what I can tell it never reads the object layer, so it never gets added to the layers list. More info would be great!

Nick,
thanks a lot for this! Could you maybe add a little example on how to do more than just draw the map? It’s not clear to me how I can access different objects from game which are in the map.
My goal is to integrate this with farseer, so I have a collision layer,where I have drawn rectangles (like your cutscenes in your examples). Now I need to get all the rectangles I have drawn in my collision layer so that I can construct the collision geometry for farseer. I know probalby a stupid question, and one that shows that I still need to learn a lot in programming, but how can I access all the objects in a layer? So that I can go trough all of them with “foreach” and create for all of them a collision rectangle.? Also, how do I read the size of such a rectangle?
Hopefully anyone can shed some light into this for me.

Hey this is very nice, thank you. I was thinking in making a loader myself, but never thought it could get that complex. But I have some problems. I’m using XNA for 6 months now, maybe, and I don’t know how to use the code you gave. There are 3 different projects on the solution. How can I use what you’ve created in my project??

I just need anyone to point me to the right direction.
Thanks.

Having been working on my own Platformer using XML and dreading the whole “I need to make a level editor now ” thing, Tiled looks to be a blessing. I shall be playing with this later tonight for sure.

Thanks!
