export-aseprite-file's Introduction

export-aseprite-file

by David Capello

This is a script that can be used to export the data from a .aseprite file into a JSON + a collection of PNG files. This script will work with Aseprite v1.2.26 and support the future v1.3 to export tilemap/tileset data.

Example

Usage:

aseprite -b map.aseprite -script export.lua

In this example export.lua will create a folder named map with some files inside:

map/
  sprite.json
  image1.png
  image2.png
  tileset1.png

An example of map/sprite.json content:
