rolando: shiny cocos supports TMX format, right ?
how are you rendering the map ? are you rendering each tile at the time? or are you creating an atlas texture in runtime with all the tiles, and you just render the atlas sprite manager ?
I would like to support the TMX format in objc-cocos2d since it supports tiled, hex and isometric tiles.
it seems that you can use spritesheets in Tiled, and if you do so, there is no need to use export the spritesheet as individual images.
I'll play with it.
Sorry for the delay, I'm just returning from vacations :-)
The parsing of the tmx file is being done in ruby, but it can be easily ported to Objective-C using NSXMLParser, or something like that. What I did was basically just a modification of TileMapAtlas.m, and using the data field of the tmx file. You can take a look at SC_TiledMap.m and map_reader.rb to see how it was implemented.
The parser is in ruby because it was easier for me to implement it, and because there's no need for real "speed": the xml files are usually small and the parsing is (most of the times) done only once.

Riq:
Not sure if you've seen this:
http://bitbucket.org/maikg/tiled2cocos/src/
It's written in Python and targets Cocos2d Python, not Cocos2d Iphone, but I'm guessing converting Python to Objective C might be easier for you than working with ruby.

thanks for the tips.
I'll use NSXMLParser + zlib and I'll use AtlasSpriteManager to render the tiles.
Each tile will be an AtlasSprite (like in BitmapFontAtlas).
So, it will be possible to get/add/remove/rotate/scale/move each tile in runtime.
TMX layers:
* each layer will be a different AtlasSpriteManager
TMX tilesets:
* initial version won't support different tilesets (but future version will).
That sounds great! Is there anything I can be doing to help with the different Tilesets in the mean time?
I don't really understand how an atlas sprite could be used with a Hex tileset? I guess the Hex tiles would have to be separated so they could fit into individual rectangles?
@sunsu: yes, you could help with TMX examples.
eg:
1 orthogonal tiled map
1 hex tiled map
1 isometric tiled map
tiles:
the maps should only use 1 tile-set.
the tile-set should be composed of 1 image (texture atlas)
ideally, the maps should have more than 1 layer (to test the layers)
tile-sets:
ideally the tile-sets should have a tile-spacing > 1 (eg: 2)
optional: have a tile-margin
how to:
1) create a new map (File -> New -> )
2) add the tileset (Tileset -> Add new -> )
3) save:
3.1) Preference: Edit -> Preferences -> saving:
binary encondig: ON
compress gzip: ON
Embed images (PNG): OFF
3.2) Save. File -> Save As: TMX
Once you have the, could you send the .tmx and .png files to my email ?
thanks.
1 week or 2 (but it can be more or it can be less).
If you start coding it, please tell us in this thread.
And if you open source it (which would be great), please, let us know too.
cool.
r1192 contains a TMX parser (not rendered), but it is an initial step.
nice!
in r1194 ortho rendering is working.
regarding the black lines... mmm....
could you send me your isometric files at my email: ricardoquesada gmail com ?
thanks. isometric and layers integrated in r1195
r1197
iso / ortho is working pretty good.
I've added a tool in tools, called "spritesheet-blink-fixer.py" that modifies the .png by copying the "border" pixels of the tiles, in the "spacing" area.
The tiles should have an spacing of 2 pixel to work.
benefits of this tool:
- no more blinks / artifacts in tiles (with aliased tiles and 2d projection)
- and... no artifacts with anti-aliased tiles! and 3d projection
cons:
- it consumes 2 more pixels width & height per tile.
next week I'll write a tutorial about this tool and the TMX support.
probably the only sample that works in trunk (r1197) is "TileMapTest". The others were not updated, and they need to link against zlib.
Hex TMX maps are not supported yet, but adding support for them is relatively easy.

Awesome work Riq, the spritesheet-artifact-fixer is a great tool. I wasn't looking forward to writing something like that myself.
left-right edges (supported):
/-\
\_/top-bottom edges (not supported by Tiled neither by cocos2d):
/\

\/i've just added support for "map tile size", which could be different from the actual tile size.
for more info, see screenshot number 2:
http://www.cocos2d-iphone.org/wiki/doku.php/prog_guide:tiled_maps
updated documentation:
- added how to read/modify/delete a tile
- coords system
- GID
