While trying to figure out how to add a custom object to the game like a piece of furniture or such i noticed it seems quite possible to use sprites that exist in the game already, however i couldnt find a reference list anywhere. I did find this topic by KillerStarBunny: http://theindiestone.com/forums/index.php/topic/2473-how-to-mod-the-textures/ In that topic, the user Minic90 posted a program that unpacks the texture files and creates a XML containing information about individual sprites etc. Looking up the sprites in the XML is a daunting task though, not only is the list very long but it also does not seem to have the sprite info ordered in a logical way. So i have written a small php script on my local server to process both the XML and image data and have it cook up some sort of reference sheets for the sprites. The result is something like this: To find a sprite name for usage in your code simply locate the sprite and note its white numbers, get the category name of the sprite from the black bar to the right and merge category + underscore + spritenumber. For the first topleft image this would be: carpentry_01_26. Works for most sprites, except for the really small ones where numbers start to overlap and become unreadable. Anyways might be usefull to some. Download: http://www.mediafire.com/download/q7m936gh2mgtt5g/TilesEdit.rar Rar archive with all the converted sprite sheets. Thanks to KillerStarBunny for the explanation on texturepacks and Minic90 for the texture unpacker!
