Project management

This page covers the lifecycle of a project: starting a new one, saving it (to your computer or to your Bilup account), loading it back, sharing it, and remixing. Most of these actions live in the File menu.

New project

File, New clears the workspace and starts a fresh project with one sprite (Misty). If the current project has unsaved changes you are warned first, because a new project replaces what is open.

Saving

There are two independent places a project can be saved: to your computer as a file, or to your Bilup account online. They do not conflict; a project can be both.

Save to your computer

  • File, Save to (filename) or Save as writes an .sb3 file to disk. On browsers that support the File System Access API, saving can write back to the same file you opened; otherwise you get a normal download.
  • File, Load from your computer (Ctrl+O) opens an .sb3 from disk.

An .sb3 is a single self-contained file: a ZIP archive holding project.json (all sprites, scripts, variables, and settings) plus every costume and sound. It is the portable, offline copy of your project, and it works in Scratch, TurboWarp, and Bilup.

Save to Bilup

When you are signed in with a Rotur account, the File menu shows Save to Bilup (and Save now / Ctrl+S saves to your account once the project lives there). This uploads the project to your account so you can reach it from any device through the community site.

  • Uploading is not publishing. A saved project stays private to you until you share it.
  • Bilup uploads assets efficiently, sending only costumes and sounds it does not already have, so re-saving a project is fast.

To make a copy that saves independently, use File, Save as a copy (Ctrl+Shift+S).

Sharing

Sharing is done on the community site, not from the editor's save action. Once a project is saved to your Bilup account, open its project page (File, See project page, or the account area on the menu bar) and use the Share button there. Sharing makes the project visible to others and gives it a public page and player. You control visibility from the site.

Remixing

A remix starts a new project based on an existing one, crediting the original. File, Remix (or Remix to Bilup when signed in) creates your own copy that you can change and save separately, without touching the original. Remixing is how you build on someone else's shared project.

Autosave and restore points

Two safety nets run while you work:

  • Restore points periodically snapshot the whole project into your browser so you can roll back after a mistake or crash.
  • Optional autosave re-saves the project to its current location on a timer.

Neither replaces saving deliberately, but both reduce the cost of forgetting.
