Since my DBP importer didn't get much attention in program announcements, I thought I'd post my AppGameKit version here. Took about the past 6 hours to write. Demo attached complete with all source code for the library.

All 3 map types are supported: Orthogonal, isometric rotated, and isometric staggered.

Hold the left mouse button down to move the map around. Keys 1-4 will load different maps, with the zelda map taking the longest to load.



I did some loading tests between my AppGameKit and DBP versions. I like AppGameKit! The load time for the large zelda overworld map was almost 10x faster! But that's probably mostly due to the different xml parser I made for it.



The commands work using a tile index to reference locations on the map. If you want grid coordinates, the following equation will work regardless of map type.




Commands:
tmx_LoadMap(string filename)
tmx_FreeMap()
tmx_DrawGridTile(int tileIndex, int red, int green, int blue)
tmx_SetMapPosition(int x, int y)
tmx_SetMapVisible(boolean)
int = tmx_GetTileIndex(int layer, int worldX, int worldY)



Unlike the DBP version, this one doesn't store the collision boxes from the map file but can be easily added.

Thanks Phaelax! This is a very welcome addition to the AppGameKit codebase. Can't wait to test it! (But that might take some time since I became a father last saturday. An incredibly happy event, but disastrous for my 'spare-time hobby)

Is that the stickied snippet thread?

No, I haven't messed with Tier 2 at all. But I'm making a DBP plugin right now

Great job Phaelax!

I'm a bit new to AppGameKit and search the forum often for placement/tile editor tool as it speeds up making games like sidescrollers. I like the tool you posted here as it supports tiled layers but somehow I get an error when creating my own TMX files with TILED having more then one layer. The example proves multiple layers are possible in your code but I can't figure out why my own TMX file gives an error... Using the code with one layer in the TMX runs ok.

the error I get when having 2 layers:

Failed to clone sprite, Sprite 0 does not exist at line 357 in tmx_engine.agcf

thanks for helping me (and others perhaps)

Can you send the tmx file and tileset image and I'll see what's going on.
My guess at the moment is that it isn't loading the tileset image and therefore the base sprite isn't being created.

Not sure I stated this, but the file must be saved in XML format and the TSX tileset is not supported (though it could be implemented easily). And no Base64, gzip, or zlib.

I've written a Base64 encoder/decoder in DB, so I think that part would at least be possible in the future.

I just found out that when using the "make duplicate layer" button to create a new layer in Tiled, the issue has gone

oops, need to correct previous post: issue does not occur anymore when all tiles are filled in the second layer (so no tile gid id's in the xml with value 0)

still, a bit strange as the example file does has gid id's with value 0???

haliop I have a c++ tmx loader in the forums it is a year old but it does the trick. Phaelox code looks good I might use it as an export for my editor to my sprite engine. Since I am not that good at basic part of agk.

Yes.

I'm working on a plugin for DBP that will hopefully support all the compression as well. I'll likely release the source code and that should make it easier for anyone who wants to do this in Tier2. Did you use an existing library for the JSON?
