Aseprite Add-ons

This repository developed out of the Medium article, "How To Script Aseprite Tools in Lua".

To install, click on the green Code button above. For those unfamiliar with Git, select Download ZIP, then unzip the file after it has finished downloading. In Aseprite, go to File > Scripts > Open Scripts Folder. Copy commands, dialog and support folders from the unzipped download into the folder that Aseprite has opened. Return to Aseprite, go to File > Scripts > Rescan Scripts Folder.

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

Scripts can be assigned shortcuts under Edit > Keyboard Shortcuts. Dialog buttons can be used from the keyboard 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".
