Jaxcore VirtualSpin

VirtualSpin is a low-level Matter.js-based physics simulation of a Jaxcore Spin device, exposed as a shared JavaScript library that is used between multiple projects, such as the Jaxcore Spin Simulator and Spin-A-Sketch.

Install and Build

git clone https://github.com/jaxcore/jaxcore-virtualspin.git
cd jaxcore-virtualspin
npm install
npm run build

Run web visualization

Serve ./build/ with any web server. On Mac/Linux if Python is installed type:

cd build
python -m SimpleHTTPServer

For Windows:

cd build
python -m http.server

Then visit http://localhost:8000 to see the Matter.js visualization. Open the web console to view the simulated Jaxcore Spin events (spin, button, knob).

Node Module

The library can be imported into other projects:

npm install jaxcore-virtualspin --save

Capture spin, button, and knob events:

import VirtualSpin from 'jaxcore-virtualspin';

let vspin = new VirtualSpin({
    friction: 0.1
});

vspin.on('spin', direction, position) {
    console.log('spin', direction, 'position', position);
});

vspin.on('button', pushed) {
    console.log('button', pushed);
});

vspin.on('knob', pushed) {
    console.log('knob', pushed);
});

vspin.on('rotate', function(angle) {
    // precise angle in radians generated by Matter.js
    console.log('angle = '+angle);
});

vspin.startSimulation();
