preload.io-pixi v1.0.0

preload.io-pixi

Preload.io wrapper for pixi.loader

Installation

npm i -S preload.io-image

Polyfills

Image requires a few polyfills to work everywhere, to give some flexibility they are not included by default.

npm i -S whatwg-fetch regenerator

import 'regenerator/runtime'
import 'whatwg-fetch'

Regenerator is currently a requirement for the async stuff, but a version is included with babel-polyfill so if you’re using that then you’re good to go. Use whichever version of fetch you like, if necessary.

There will be a fairly obvious console error logged if these are omitted.

Getting Started

Install preload.io and register the image loader with it

import Preloader from 'preload.io'
import { EVENTS } from 'preload.io'
import PixiLoader from 'preload.io-pixi'

let preloader = new Preloader()
preloader.register( new PixiLoader() )

Then load the resource and it’ll be preloaded by the browser, cached in both browser cache and the pixi loader cache

preloader.load( '/assets/avatar.jpg' )

Matches

PixiLoader will match on jpg, jpeg and png resources.

This will conflict with Preload.io-image so specify the loader to use if you need to whack images into Pixi and you’ve registered preload.io-image:

let pixiLoader = new PixiLoader()
preloader.load({
  resource: '/assets/avatar.jpg',
  loader: pixiLoader.name
})

Passing options through to Resource-Loader

Pixi.Loader is built on top of Resource-Loader which accepts a couple of parameters, this PixiLoader plugin passes those options straight through.

let pixiLoader = new PixiLoader({
  baseUrl: '/assets',
  concurrency: 10
})

Using textures returned from images

The currently supported use-case is to use PixiLoader to load images (the underlying pixi loader is smarter than that) and those textures will be exposed on the load and complete events returned by Preload.io

import Preloader from 'preload.io'
import { EVENTS } from 'preload.io'
import PixiLoader from 'preload.io-pixi'

let preloader = new Preloader()
preloader.register( new PixiLoader() )

preloader.load({
  id: 'avatar',
  resource: '/assets/avatar.jpg'
})

preloader.on( EVENTS.COMPLETE, resources => {
  let texture = resources.get( 'avatar' ).texture
  // ... Do stuff with `texture`
})
