wellcaffeinated / renderer-pixi.js
Created January 8, 2014 16:21
Very rough implementation of a pixi.js renderer for PhysicsJS. Only supports circles right now.
Physics.renderer('pixi', 'canvas', function( parent ){
return {
init: function( options ){
// create an new instance of a pixi stage
this.stage = new PIXI.Stage(0xffffff);
// create a renderer instance.
this.renderer = PIXI.autoDetectRenderer(options.width, options.height);

Utilities for working in codesandbox that help workflow, especially when animations and loops are involved
const elCache = new Map()
// This helps fix the annoying disappearing of dom elements on csb save.
// Use $() or $$() to retrieve your dom elements in loops
const createQuerySelectorUtil = (qs) => (query) => {
let el = elCache.get(query)
if (el && document.body.contains(el)) {
return el
}
el = qs(query)
elCache.set(query, el)
