Pixels Web Package

This is the Pixels web package for front end web developers. It enables communications between Pixels dice and a web browser using Bluetooth Low Energy.

This package relies on the Web Bluetooth API for accessing Bluetooth. At the time of writing, only Chrome, Edge and Opera browsers have support for these APIs.

Currently all testing is done with the latest Chrome on Windows 10.

If you're on Linux, you may need to first set this flag to enable the Web Bluetooth API: chrome://flags/#enable-experimental-web-platform-features. However be careful as it would be risky to browse the web with this flag turned on as it enables many other experimental web platform features.

Starting with Chrome version 100, there will be a safer flag to use: chrome://flags/#enable-web-bluetooth.

Please open a ticket in GitHub if you're having any issue.

Getting Started

To install the package:

npm i pixels-library

Start by calling the requestPixel function to request the user to select a Pixel die to connect to.

This function returns a Pixel object. Call the connect asynchronous method to initiate a Bluetooth connection with the die.

The Pixel class has a number of methods to retrieve information about the die state. It also let you add a listener for any Pixel message (as defined in MessageTypeValues).

Connection & Messages

import { Pixel } from "pixels-library";

// Ask user to select a Pixel
const pixel = await Pixel.requestPixel();
console.log("Connecting...");
await pixel.connect();

// Get some info
const rollState = await pixel.getRollState();
console.log(`=> roll state: ${rollState.state}, face ${rollState.faceIndex}`);
const battery = await pixel.getBatteryLevel();
console.log(`=> battery: ${battery.level}, ${battery.voltage}v`);
const rssi = await pixel.getRssi();
console.log(`=> rssi: ${rssi}`);
const rssi = await pixel.blink(Color.red);

// Add listener to get notified when the Pixel roll state changes
pixel.addEventListener("messageRollState", (ev: CustomEvent<MessageOrType>) => {
// Or: pixel.addMessageListener(MessageTypeValues.RollState, (ev: CustomEvent<MessageOrType>) => {
    const msg = ev.detail as RollState;
    console.log(`=> roll state: ${msg.state}, face ${msg.faceIndex + 1}`);
});

Testing Animations

Animation editing classes are available in a separate package: @systemic-games/pixels-edit-animation.

import {
  EditDataSet,
  EditAnimationRainbow,
} from "@systemic-games/pixels-edit-animation";

// Create a simple rainbow animation
const editDataSet = new EditDataSet();
editDataSet.animations.push(
    new EditAnimationRainbow({
        duration: 3,
        count: 2,
        fade: 0.5,
    })
);
// And play it on the Pixel die
await pixel.playTestAnimation(editDataSet.toDataSet());
