Aseprite Add-ons

This repository developed out of the Medium article, "How To Script Aseprite Tools in Lua". Short demonstrations for some the scripts here can be found in this Youtube playlist.

Installation

To install, click on the green Code button above. Select Download ZIP from the pop-up menu. Unzip the file after it has finished downloading. In Aseprite, go to File > Scripts > Open Scripts Folder. Copy commands, dialogs and support folders from the unzipped download into the folder that Aseprite has opened. Return to Aseprite, go to File > Scripts > Rescan Scripts Folder.

There is a known issue when Aseprite's script folder is on a file path that includes characters such as 'é' (e acute) or 'ö' (o umlaut).

Usage

Aseprite version 1.3.17 is the minimum supported version to run these scripts.

To use, go to File > Scripts and choose from entries in the dialogs or commands folder.

Scripts can be assigned shortcuts in Edit > Keyboard Shortcuts. Dialog buttons can be called by holding down the Alt key and pressing the underlined letter of the button's label. For example, Alt+C will close dialogs, per the 'C' in "CANCEL".

Most scripts dealing with color assume standard RGB is the working color profile. The window profile is set under Edit > Preferences > Color. The sprite profile is set under Sprite > Properties.
