Sprites explained

Sprites are saved in Aseprite as a spritesheet with a json file and tga/png for each separate animation. Name the json and image the same. Now once you have all your animations saved, put them all in a directory together and in that directory create a file called sprite.json:

[ walk_e, walk_w, walk_n, walk_s, throw, jump ]

List all your animations in an array in a json file like above. Now to load a sprite, use the directory name with sprite_load. Make sure to put sprites in data/gfx/sprites.
