Anatomy of a Pixelspace App

A Pixelspace app consists of two components a Player and a Renderer. The Player is mainly responsible for setting up a context for a Renderer sub class to funtion within. Developing sketches for Pixelspace mostly involves sub-classing Renderer, creating an instance of it and passing it to the Player. Below is a very basic ES6 example of this.

import Pixelspace from 'lib/pixelspace';

class CustomApp extends Pixelspace.Renderer {
  init() { /* initialize variables here */ }

  step() { /* update variables here */ }

  draw() { /* draw graphics here */ }
}

let canvas = document.getElementById("canvas");
let player = new Pixelspace.Player(canvas);
let custom_app = new CustomApp();
player.setRenderer(custom_app);
player.play();
