Texture Atlas in reverse?
What if we start with an image that has all our sprites in it, but do not have a plist to sort it out. What is the preferred method to 'reverse engineer' the plist or how to create an atlas when all the sprites are on a single image already? For Example, a deck of playing cards....
To do this you could load the texture then use the textureWithRect method where you would pass the rect that is the individual piece you want out of the whole sheet, say for each card.
SKTexture *temp = [SKTexture textureWithRect:piece inTexture:sheet];
Sheet would be the original texture piece is a CGRect of size and location inside the sheet for the piece you want
temp would be the resulting texture.
