I've just posted in a blog a summary of the cocos2d editors that were posted in the forum in that lasts months:
http://www.cocos2d-iphone.org/archives/534
Basically it mentions:
- Tiled (for tiles)
- Zwoptex and mkatlas.pl (for Sprites)
- Hiero and BMFont (for BitmapFontAtlas)
- charmap and GIMP plugin (for LabelAtlas)
- LabelAtlasEditor (for ALLabelTlas)
Did I miss any editor ? thanks.
