URL: http://particlesandbox.com
GitHub: https://github.com/apexearth/particle-sandbox
App Class: https://github.com/apexearth/particle-sandbox/blob/develop/app/ParticleSandbox.js#L25

Basic Usage

  1. Create an App.
  2. Add AppObjects to it.
  3. Create a renderer for the App.
  4. The renderer starts the update & draw loop, rendering the App.
const {
   App,
   AppObject,
   createRenderer,
   PIXI,
   setting,
   properties,
   property 
= require('apex-app')
 
// Extend App
// Initialize with a single AppObject drawn as a white square.
class Game extends App {
   constructor() {
       super()
       let obj = new AppObject({parent: this})
       obj.graphics.beginFill(0xffffff, 1)
       obj.graphics.drawRect(0, 0, 10, 10)
       obj.graphics.endFill()
       this.add(obj)
   }
}
 
// Create renderer and attach canvas to `document.body`.
createRenderer(new Game(), {
   rendererOptions: {
       backgroundColor: 0x333333
   }
})
