Two short scripts drop 300 cubes with physics. Try this project.
Features
The editor. This script climbs in a spiral with the pen down, then draws a wireframe cube.
- Scratch's blocks, in 3D. Sprites are cubes, spheres, cones and cylinders on a 3D stage. Motion gets a z axis, pitch and roll; events, control, clones, variables and broadcasts work as in Scratch.
- The pen draws in space: lines, and wireframe cubes and spheres.
- Stage editing like Tinkercad. Drag a sprite to move it, drag the cone above it to lift it, and orbit, pan and zoom the camera.
- Physics as an extension, with Rapier: sprites fall, collide and stack.
- Share with a link. Shared projects play on phones too, with on-screen keys for projects that use the keyboard, and anyone can open one with "See inside" to remix it.
- Made for children. No accounts and no personal data; sharing is by link only, with no public gallery or comments.
- In English and Japanese.
BeeCube is under active development: sounds and costumes are not done yet. The editor is designed for computers with a mouse and keyboard.
Run it locally
Requires a current Node.js LTS release (CI uses Node.js 24).
cd app
npm install
npm run dev
Then open the URL that Vite prints. See app/README.md for tests, benchmarks, the source layout, the sharing API and how the engine works.
