Class Accel

Introducing Accel (accelerometer, on mobile) support for WebChucK. Accel wraps JavaScript DeviceMotionEvent listeners easing access to mobile device accelerometers in WebChucK code.

To get started with Accel:

import { Chuck, Accel } from "webchuck";

const theChuck = await Chuck.init([]);
const accel = await Accel.init(theChuck); // Initialize Accel
Copy

The devicemotion event gives the acceleration of the device on the three axes: x, y, and z. Acceleration is expressed in m/s². More on the devicemotion event can be found online here.

iOS devices require that the web developer ask permission from the user to access sensors after a button push. This looks like:

let runButton = document.getElementById("run");

runButton.addEventListener("click", async () => {
  // Request iOS accelerometer permission
  if (typeof DeviceMotionEvent.requestPermission === 'function') {
    await DeviceMotionEvent.requestPermission();
  }

  await theChuck.loadFile("./yourChuckCode.ck");
  theChuck.runFile("yourChuckCode.ck");
});
