I'm working on a project using ReactJS with Pixi & GSAP and the js library I'm using is called "react-pixi-fiber".

I'm trying to reference the React Pixi Sprite object and handling the animation it using GSAP. 

However, it changes position without easing, and there's no error message showing.


Code as below


The "moveEle" function will be called from the parent component.


class MainObject extends Component {
constructor(props) {
this.state = {
this._refEle = React.createRef();

moveEle = options => {

TweenLite.to(this._refEle, options.duration, {
x: options.x,
y: options.y,


render() {

return (
<Fragment key="MainElesFragment">
ref={div => (this._refEle = div)}

Welcome to the forums, @mogwai. We'd love to help, but just seeing a snippet of code doesn't really help - we need to see the issue in context. Would you please provide a reduced test case in codepen or stackblitz or something like that? It kinda sounds like maybe you have something else controlling that animation rather than just GSAP (like something is fighting with GSAP)? Totally a guess. You seem to have defined the ease correctly, though I don't see any imports nor do I see if you're correctly loading CSSPlugin (which would be necessary to animate CSS-related properties).

It doesn't need the CSSPlugin. It's React for PixiJS.


Ha. Yeah, I'm so used to associating React with animating regular DOM elements but you're right - if it's Pixi then no CSSPlugin is needed. 


@mogwai can you provide a reduced test case so we can take a peek?
