a simple and powerful pixi.js easing/tweening/animating library
- ease any pixi.js parameter, including tint (using a blend function or stepped)
- use any Penner function by name or any user-defined function
- support for generic number parameters
- change scale or skew using one parameter (e.g., scale: 5 changes both scale.x and scale.y)
- set default durations and easing function for all eases
- uses eventemitter3 for events for both the easing lists and individual eases
- tracks eases on DisplayObject and cleans up when DisplayObject is destroyed
- includes a default easing list so you don't have to instantiate for simple cases
- includes a shake parameter
- good test coverage

- changed default update loop to use requestAnimationFrame to remove the dependency on pixi.js
- to use PIXI.Ticker (like in v2), pass
new Ease({ ticker: PIXI.Ticker.shared }) - ordinary usage should be unchanged
yarn add pixi-ease

import * as PIXI from 'pixi.js'
import { Ease, ease } from 'pixi-ease'
const app = new PIXI.Application()
const test = app.stage.addChild(new PIXI.Sprite(PIXI.Texture.WHITE))
test.tint = 0x00ff00
const example = ease.add(test, { x: 20, y: 15, alpha: 0.25, rotation: 20, scale: 5, skewX: 0.25, blend: 0xff0000 } }, { reverse: true, duration: 2500, ease: 'easeInOutQuad' })
example.on('each', () => console.log('ease updated object during frame using PIXI.Ticker.'))
example.once('complete', () => console.log('move ease complete.'))
test.generic = 25
const generic = ease.add(test, { generic: 0 }, { duration: 1500, ease: 'easeOutQuad' })
generic.on('each', () => console.log(test.generic))
const secondEase = new Ease({ duration: 3000, wait: 1500, ease: 'easeInBack', repeat: 3 })
const test2 = app.stage.addChild(new PIXI.Sprite(PIXI.Texture.WHITE))
secondEase.add(test2, { tint: [0xff0000, 0x00ff00, 0x000ff], scaleX: 2 })I've included a bunch of build examples in the builds directory, including: browserify, rollup, standalone (e.g., cdn), standalone (pixi.js v4), and typescript.
