scratch-vm-injection

You can automate Scratch programming by injecting blocks directly into the web editor's Virtual Machine (VM) using Playwright. This approach bypasses manual dragging by programmatically serializing and deserializing project JSON to create and modify scripts.

Scratch VM injection is a technique that automates code generation by interacting directly with the Scratch Virtual Machine. It works by using Playwright to evaluate browser logic, serialize project JSON, and inject block definitions into sprites programmatically.

Yes, you can generate entire Scratch projects programmatically by defining sprite blocks and managing sprites through project JSON serialization. This allows you to quickly create educational games or complex geometric drawing scripts based on predefined logic.

Yes, Scratch VM injection requires Playwright to execute browser evaluation and interact with the Scratch web editor's VM. It uses Playwright to automate the injection of blocks and execution of project logic within the browser environment.

You make a sprite move by defining the block logic in code and injecting it into the sprite's JSON structure via the Scratch VM. This programmatically adds the green flag event and move steps blocks without manual editor interaction.

Modifying Scratch projects through JSON manipulation requires understanding the Scratch VM's internal project structure. Complex scripts must be accurately serialized and deserialized to avoid corrupting the project file when injecting blocks programmatically.
