Use when the user wants to generate a .sb3 file with sprites, scripts, and assets. license MIT compatibility claude-code opencode github-copilot devin pi cursor Scratch Coder Create Scratch 3.0 projects with Python and ScratchGen. Setup pip install "ScratchGen~=1.1" Quick start from ScratchGen import * project = Project() sprite = project.createSprite( 'Cat' ) sprite.createScript( WhenFlagClicked(), Show(), Say( 'Hello!' ) ) project.save( 'hello.sb3' ) Common pitfalls Sprites are hidden by default. Call Show() in WhenFlagClicked() . Sprites have no default costume. Add costumes via addCostume() or inject them after saving. Broadcast() / WhenBroadcastReceived() use null IDs in ScratchGen. Use ChangeVariable on global stage variables for cross-sprite state instead. GetAttribute requires ScratchGen constants, not strings: GetAttribute(Y_POSITION, ball) . Stop(ALL) clears speech bubbles before rendering. Use a game_over state variable plus a dedicated message sprite. Stage fence clamps sprites at y = -180 to 180 . Keep detection thresholds inside the bounds. Stage coordinates x: -240 to 240 y: -180 to 180 Physics tips Keep MoveSteps(N) <= half the target sprite's width to avoid tunneling. For axis-aligned games, store direction as dx / dy stage variables and move with ChangeX(Multiply(dx, speed)) . Save pipeline project.save() -> add_costumes() -> add_monitors() Testing python -c "import zipfile; print(zipfile.ZipFile('project.sb3').namelist())" Open the file in TurboWarp to verify.
