The backpack
The backpack is a collapsible bar along the bottom of the editor that stores scripts and assets so you can carry them between sprites and between projects. It is the easiest way to move a block stack from one sprite to another, or reuse a costume in a different project.
What it holds
The backpack stores four kinds of item:
- Scripts (a stack of blocks)
- Sprites
- Costumes
- Sounds
Adding and using items
- Add: drag an item onto the open backpack bar. Drag a script from the workspace, or a tile from the sprite pane, costumes list, or sounds list.
- Use: drag an item out of the backpack into the editor. A script drops into the workspace; a costume or sound drops into the relevant list; a sprite drops into the sprite pane.
Click the Backpack header at the bottom of the window to open or close it. When open you get a search box (search by name, or by type words like "code", "image", or "audio"), and you can drag the top edge to make the bar taller. Each item can be renamed or deleted from the backpack (sprites cannot be renamed here). Your chosen height is remembered.
Persistence
The backpack is tied to your account, not to a single project, so items you put in it stay available across projects and sessions. This makes it a personal library of reusable pieces.
Hiding it
The Hide Backpack setting removes the backpack bar, and Ctrl+Shift+B toggles it. On builds where no backpack storage is configured, the bar shows as unavailable.
