Walk into it in Phantom
Install the plugin in Developer mode in the desktop app, and its command walks you in.
Lay out a room for Animal Jam Classic and download it as a Phantom plugin. It runs in your browser, so nothing is uploaded and you don’t need an account.
A zipped plugin folder, the same one npm create @phantomclient/plugin makes. It builds and publishes like any other plugin.
Open a .xroom file and pull it apart: its grid, doors, arrival points, bouncing areas and art. Anything a room plugin can’t hold is listed before it opens, and your file is only read.
The game’s art is SWF and browsers can’t play Flash, so it shows as named boxes at the right size.
Your pictures are read in the browser and never sent anywhere. The room is saved in this browser, so you can close the tab and come back, but clearing the site’s data clears it too. The download is your copy, and it opens here again.
Use art you have the right to use. Rooms published to Phantom’s store are reviewed by a person.
