Images in forms. A new image element places a picture in a form's body, sized as a percentage of the form width, decorative or clickable. Buttons can carry picture art too. Both use Bedrock's data-driven UI image API (CustomForm.image / button imageDetails), so they're on the DDUI (Preview) profile — the editor exports the picture into the resource pack for you and points the generated scripts at it.
Corrected the DDUI profile. The data-driven UI classes (custom forms, message boxes, observables, the close button) are stable as of @minecraft/server-ui 2.1.0 and need no experiment — Canvas previously treated them as beta. The DDUI profile now targets the 2.3.0-beta image API, and its runtime drives the real observable/callback model rather than the stable form's response model.
0.1.0 — first release
Visual form designer for Minecraft: Bedrock. Build action menus, modal input forms, and two-button message boxes as a vertical stack of elements, with a faithful in-editor preview of how each will look in game.
Logic without code. Give any button or submit an ordered list of actions — open another form, run a command, send a message, set a score, give an item, teleport, play a sound, add or remove a tag. Values the player typed can be piped straight into commands.
Play mode. Click through your form chain in the browser, with a console showing exactly what each action would do in game.
Export a working pack. One click produces an .mcaddon containing a behaviour pack with generated scripts, plus a resource pack when you use custom icons. A second click produces a test .mcworld with the packs already installed and activated.
Four ways in. Open the root form with a custom command (/canvas:open, no cheats needed), a held item, /scriptevent, or automatically when a player joins.
Validation catches the mistakes that are painful to debug in game: dead-end buttons, message forms without exactly two buttons, broken form links, missing icons, and DDUI features used on the stable profile.
Undo everything, with a labelled history you can jump around in.
