Sorry if this is the wrong board. I needed to create Texture Atlases for my sprites in game, and a quick google search led me to TexturePacker. However, that is not a free solution and I don't like spending money on task I can write my own code for Before creating my own Texture atlas creator however, I stumbled upon http://spritesheetpacker.codeplex.com/ This tool seemed to bascially do what I wanted with the added cost of being free, but it did not output to a format readable by Phaser. So I wrote a DLL to allow it to do so! Pretty easy to use. Just download spritesheetpacker and put SpriteSheetPacker.JsonExporters.txt in the same directory as the executable, and change the extension from .txt to .dll. I should mention the .json file is in the hash format. The JSONExporter.txt isn't neccessary, it's just source if anybody cares. SpriteSheetPacker.JsonExporters.txt JSONExporter.txt
