What I'm trying to do? I've got 2 images on top of each other I want to alpha-in (opacity) via the blend-mix-mode layer with ScrollTrigger. position: relative; height: 100vh; width: 100vw; overflow-y: scroll; } img { min-width: 100vw; max-width: 100vw; height: 200vh; position: absolute; object-fit: cover; &#imageOne{ overflow-y: scroll; } &#imageTwo { overflow-y: scroll; mix-blend-mode: multiply; } } I'm having trouble just getting the images to animate with a scroll bar. I'm using big images about 5000px in size becuase I want them to be in a container with a scroll bar that I can use as the 'Scroller' for the Opacity for the image with blend modes on. What I've come up with: So far not really much luck. Here is a running view of what I've got so far. https://react-pvbx1r.stackblitz.io/ I have the project here you can see the code at the bottom is the images and the styling is in BackgroundStyle. I feel I have got the right Idea with GSAP in using useEffect to set options after the DOM has been rendered and using useRef for referencing Nodes to give to GSAP. But I don't think my problem is with React. I just cant seem to get the scroll and the animation to work. Here is the Editor link https://stackblitz.com/edit/react-pvbx1r?file=src/components/landing.js Thanks P.S I'm learning a bunch of frameworks at the moemnt so there is a chance im using quite a lot of this stuff wrong, if you spot any bits that aren't written well I would be very gratefull if you highlighted them! All the best

I created a timeline animation which runs on click event. Animations are working smoothly only after few refresh in most of the browsers. Below is my function with timeline.. function exploreTimeline() { gsap.timeline() . to("body", { position: "static", overflow: "auto" }) . to(".intro-content", { duration: 0.3, autoAlpha: 0.01, marginLeft: 50, ease: "power1" }, 0) . to(".intro-content", { duration: 0.8, height: 0, marginBottom: 0, ease: "power2.in" }, 0) . to(".intro-section", { background: "none" }, 0) . to(".globe", { filter: "blur(5px)" }, 0) . to(".magical-slider-container", { duration: 0.8, bottom: "5%", ease: "none", onComplete: () => { ScrollTrigger.refresh(); } }, 0) }

Hi, I want to use gsap to animate the two pseudo elements (::before and ::after) of my buttons. The each button element is inside a Group component in my react project. I want to play the animations on ::before and ::after alternately. Here is my code: import React, { useState } from "react"; import { gsap } from "gsap"; import { CSSRulePlugin } from "gsap/CSSRulePlugin"; const animation = (qseudoElement) => { gsap.registerPlugin(CSSRulePlugin); const qseudo = CSSRulePlugin.getRule(qseudoElement); const tl = gsap.timeline(); tl.fromTo( qseudo, { cssRule: { opacity: 0, scale: 0 } }, { cssRule: { opacity: 1, scale: 1 }, duration: 1 } ); tl.to(qseudo, { cssRule: { scale: 0, opacity: 0 }, duration: 1 }); }; const Group = () => { const [count, setCount] = useState(0); const handleClick = () => { setCount(count + 1); if (count % 2 === 0) { animation(".btn::before"); } else { animation(".btn::after"); } }; return ( <div> <button className="btn" onClick={() => handleClick()}>Click Me</button> </div> ); }; export default Group; And I have multiple Group components in my App. import Group from "./components/Group"; import "./styles.css"; export default function App() { return ( <div className="App"> <Group /> <Group /> <Group /> </div> ); } The problem is that if I click on any button, the animations are fire on all buttons. I know this is because of they have the same css class. How can I select the button that is clicked and animate its pseudo elements? I want to achieve something like this: const handleClick = (e) => { setCount(count + 1); if(count % 2 === 0){ animation(e::before); } else { animation(e::after); } } I appreciate your help and I made a demo here: codesandbox

Hello everyone, I would like to develop this kind of animation for my background. Anybody suggest me about this how can I develop this? Also how can I add liquid hover effect on images. https://s.muz.li/NzNjY2YzNGRi Thanks

Hi ! Apologies in advance, I'm a musician / digital artist and a total beginner with gsap (like 2 days ago) but also very new to Js, React and Three.js. I'm really amazed how easily gsap handles animation of any params compared to other solutions I found in the past. It will make my life so much easier, I'm already considering to join the Greensock club soon...! Since yesterday I've been hitting my head against the wall and I can't figure this out. Here's the sandbox : https://7cuco.csb.app I have this button that triggers random variations of color and rotation speed of a cube. I wanted gsap to smooth every random value by a few seconds. I managed to make this happen very easily for the rotation speed (I guess because I worked from a simple object) but for some reason it doesn't work as excepted with the Three.color object. Every click resets the color to black, before moving gradually to the selected color. Almost... I'm really sorry in advance, I expect this to be a really stupid mistake. Thanks in advance for your help !

Hi All, I am trying to animate something using scroll trigger (minimal reproducible example in codepen link ). I want to scale the circle to 1 when scroll progress is 25%. And for that reason I tried setting the timeline duration to 4 and the animation duration to 1 but it doesn't work. It still takes the full progress of the scroll trigger to make it scale to 1. Your help is highly appreciated. Thanks Edit: Codepen doesn't seem to be working. Here is a code sandbox instead https://codesandbox.io/s/gsap-scrolll-blimx?file=/src/App.js:0-1097

I am having an issue I have seen described in other contexts but haven't found a solution for. My project is using the Next.js framework for react, Smooth Scrollbar, and ScrollTrigger. I have a .to() with a scrollTrigger object inside that is in a <Navigation /> component. The text at the top of the page is just supposed to pin itself and scroll with the window, but it only works in some cases. I think I'm not fully understanding some lifecycle thing here. All these methods of reproducing my errors are also commented at the top of the index.js file in the sandbox With Smooth Scrollbar enabled, the scrollTrigger object stored in the <Navigation /> component, and the <Navigation /> component imported and nested in the main functional component, the effect does not work after refreshing the page. If you go into the scrollTrigger object in the <Navigation /> component and update one of the values (change the 'end' value to a different number) this will trigger a hot reload without refreshing the browser. If you scroll back to the top and scroll down, you will see the effect is now working. If you comment out the entire useEffect() hook in the main index.js component this will disable Smooth Scrollbar. If you save the file and refresh you will see the effect working as intended, without having to trigger a hot reload, but now there is no Smooth Scrollbar. If you reset the sandbox to the original state, uncomment the HTML in the main index.js components return, comment out the <Navigation /> component right above it, save and then refresh, you will see that the effect works on load, with Smooth Scrollbar, without having to trigger a hot reload, but now I've lost the ability to nest components. CodeSandbox link Direct link to results in browser (A little easier for refreshing) Any help would be greatly appreciated. I'm out of ideas at this point.

Hi there! We just completed a major site redesign featuring ScrollTrigger in several modules. It's been awesome, thanks to all involved in making this happen! One issue that came up is illustrated in the Codepen. We have a few modules that "expand" with interaction, like the green Module 2. The horizontal scroll module works great, but if the module above is expanded, it throws off the start/end positions of the trigger. My initial solution was to add a resizeObserver on the height of the body, that would trigger a window.resize event. This was effective in conjunction with MatchMedia, but it's global and is interrupting other animations that are happening on-screen while the body size is changing. What's the best (and more "componentized" ) way to recalculate the trigger when its position changes like that? Note: I don't think it's necessarily relevant, but we are using React in a sort of unique set up... we are working within a modular CMS, so each module is its own React app, similar to how the Codepen is set up. Much thanks!

I've seen various threads and blog posts about using lagSmoothing() to prevent animations pausing when switching screens. Every time I try to implement solutions, I get either ___ is not a function or not a method, or cannot read property ___ of undefined or something to that effect. Here's the base animation: useEffect(() => { const timeline = new TimelineLite(); timeline.from(itemRef.current, { autoAlpha: 0, stagger: 0.5, }); }); I've tried adding a TweenLite instance, like recommended here and elsewhere useEffect(() => { const timeline = new TimelineLite(); TweenLite.ticker.useRAF(false); TweenLite.lagSmoothing(0); timeline.from(itemRef.current, { autoAlpha: 0, stagger: 0.5, }); }); I've also tried adding the fn directly to my timeline instance: useEffect(() => { const timeline = new TimelineLite(); timeline.lagSmoothing(0); timeline.from(itemRef.current, { autoAlpha: 0, stagger: 0.5, }); }); And have also tried with the updated gsap.timeline() syntax from this Stack OVerflow post. Does anyone have an example of how lagsmoothing should be used with a timeline instance?

Congratulations on the release of GSAP 3! The work you lot do both with your framework and with the support for it is just incredible, and I personally can't express how thankful I am to have this resource! https://codesandbox.io/s/friendly-ellis-yi33q?fontsize=14 So what I'm trying to do is to run an animation across a few components. In this example specifically, I'm trying to have a button that animates and opens a modal, which then animates the content of the modal. I got it all to open relatively well, but what I'm not able to figure out is how best to go about reversing the animation, and more specifically the `ModalContent.js` animation. What I want to have happen is for it to reverse the content, then transition the modal itself. I'm certain that the issues all lie in the way in which I set this up, so any suggestions on structuring this better (while still preserving the capabilities of animating across multiple components), I'm all ears. Also, am I correct in using refs for targeting the elements? Is there any type of drawback to having a fair amount of refs for animating? Thanks!

I am using Gatsby JS and initializing smooth-scrollbar within a layout component and I've also configured the scroller proxy. Within a child component, I'm trying to setup an animation using scroll trigger but I'm not sure how to configure this. Also, the config does work after HMR fires but not after page refresh. I removed most of the markup from the page as I know the animation works - I think the issue is with syncing the scrollers. layout.js: import React, { useRef, useEffect } from "react" import Navbar from "./navbar" import { gsap } from "gsap"; import { ScrollTrigger } from "gsap/ScrollTrigger"; import Scrollbar from 'smooth-scrollbar' // import "../styles/locomotive-scroll.css" const Layout = ({ children, location }) => { const scrollerRef = useRef() useEffect(() => { gsap.registerPlugin(ScrollTrigger) const scroller = scrollerRef.current const bodyScrollBar = Scrollbar.init(scrollerRef.current, { damping: 0.1, delegateTo: document, alwaysShowTracks: true }) window.bodyScrollBar = bodyScrollBar ScrollTrigger.scrollerProxy(scrollerRef.current, { scrollTop(value) { if (arguments.length) { bodyScrollBar.scrollTop = value } return bodyScrollBar.scrollTop } }) window.scroller = scrollerRef.current bodyScrollBar.addListener(ScrollTrigger.update) ScrollTrigger.defaults({ scroller: scroller }) // ScrollTrigger.refresh() return () => { if (bodyScrollBar) bodyScrollBar.destroy() bodyScrollBar.removeListener(ScrollTrigger.update) } }, [location]) return ( <div className="global-wrapper scroller h-screen overflow-hidden" ref={scrollerRef}> <header className="global-header animate__animated animate__fadeIn"> <Navbar /> </header> <main>{children}</main> <footer> {/* © {new Date().getFullYear()}, Built with */} {` `} {/* <a href="https://www.gatsbyjs.com">Gatsby</a> */} </footer> </div> ) } export default Layout index.js: import React, { useEffect, useRef } from "react" import { gsap } from "gsap"; import { ScrollTrigger } from "gsap/ScrollTrigger"; function Index() { const outroRef = useRef() const outroContentRef = useRef() useEffect(() => { gsap.registerPlugin(ScrollTrigger) gsap.fromTo(outroContentRef.current, { yPercent: "-50" }, { yPercent: "0", scrollTrigger: { scroller: window.scroller, trigger: outroRef.current, end: "bottom bottom", scrub: true, markers: true }, ease: "none" }) }, []); return ( <> {/* Page content */} </> ) } export default Index

Hi there, I'm new to Gsap and looking for a way to animate a slider that I've created using react. Now, my Slider.js component is sourcing data from contentful via Graphql so I've took a different approach to build the slider as you can see below. Slider.js import React from "react" import { graphql, useStaticQuery } from "gatsby" const query = graphql` { allContentfulExperience(filter: {node_locale: {eq: "en-US"}} ) { nodes { id slug title excerpt { excerpt } image { fluid { ...GatsbyContentfulFluid_withWebp } } } } } ` const Slider = () => { const data = useStaticQuery(query) const { allContentfulExperience: { nodes: products }, } = data const [index, setIndex] = React.useState(0); React.useEffect(() => { const lastIndex = products.length - 1; if (index < 0) { setIndex(lastIndex) } if (index > lastIndex) { setIndex(0) } }, [index, products]) return <Wrapper> <div className="section-center"> {products.map((product, productIndex) => { let position = "nextSlide" if (productIndex === index) { position = "activeSlide" } if (productIndex === index - 1 || (index === 0 && productIndex === product.length - 1)) { position = "lastSlide" } return ( <article className={position} key={productIndex}> <Image fluid={product.image.fluid} alt={product.title} className="img"></Image> <div className="info"> <h3>{product.title}</h3> <p>{product.excerpt.excerpt}</p> <StyledLinks message="View more »" linkes={product.slug} /> </div> </article> ) })} <FormPrevious className="prev" onClick={() => setIndex(index - 1)} color="white" size="large" /> <FormNext className="next" onClick={() => setIndex(index + 1)} color="white" size="large" /> </div> </Wrapper> } export default Slider I was wondering now, if I can use Gsap to animate my slider. For example, If I click the ''next button'' I want the content to animate in (I hope you get my idea.. ). Is something like that possible with the Slider that I've built? What would be the Gsap plugins that I need? I know react pretty well but not really Gsap.. Thanks in advance!

My goal is update a Three JS scene (colors, camera position, material properties, etc.) based on state properties set by the timeline. My scene is rendered inside of the BlobScene component which accepts an intensity prop. In the sample below, I'd like to update the intensity as the timeline is scrubbed which then updates the light intensity of my scene. In the pinned section, there are two columns: the left column contains text that will be translated into view and the right column contains the BlobScene. My ultimate goal is to change the color of the blob for each corresponding text section. So when the user scrolls from the red section to the green section, for example, the blob mesh would smoothly transition it's material color from red to green. Am I going about this the wrong way? I can create a minimal demo if needed. import React, { useState, useEffect } from "react" import { gsap } from "gsap"; import { ScrollTrigger } from "gsap/ScrollTrigger"; import BlobScene from '../components/blob-scene' function Index() { let [intensity, setIntensity] = useState({value: 1.5}) useEffect(() => { gsap.registerPlugin(ScrollTrigger) // Verticals Pinned Section Story const tl = gsap.timeline() tl.from(".red", {y: "100%"}) .from(".green", {y: "100%"}) .from(".blue", {y: "100%"}); // PROBLEM LINE tl.to(intensity, { value: setIntensity(0.5) }) ScrollTrigger.create({ animation: tl, trigger: "#verticals", scroller: "#___gatsby", start: "top top", end: "+=4000", scrub: true, pin: true, anticipatePin: 1 }); // each time the window updates, we should refresh ScrollTrigger and then update LocomotiveScroll. ScrollTrigger.addEventListener('refresh', () => window.scroll.update()) ScrollTrigger.refresh() }, [intensity]); return ( <React.Fragment> <div className="page"> <section id="verticals" className="h-screen flex items-center relative w-full overflow-hidden"> <div className="grid grid-cols-2 gap-6 h-full w-full"> {/* Grid Column 1 */} <div className="flex items-center"> <div className="relative w-full overflow-hidden h-80"> <div className="panel absolute h-full w-full red bg-red-500 text-black"> <h2>Panel 1</h2> </div> <div className="panel absolute h-full w-full green bg-green-500"> <h2>Panel 2</h2> </div> <div className="panel absolute h-full w-full blue bg-blue-500"> <h2>Panel 3</h2> </div> </div> </div> {/* Grid Column 2 */} <div className="flex items-center"> <BlobScene intensity={intensity.value}></BlobScene> </div> </div> </section> </div> </React.Fragment> ) } export default Index

Hi all- I'm brand new to the GSAP space. I have an existing React project and want to implement a GSAP animation. The person that made it for me sent it in an HTML file. How would I go about implementing this into my React site? I know there's a react-gsap NPM package but figured there might be an easy way to just plug the HTML doc in and get it working that way? I've attached the file to this post; if you click when it loads, it should play the animation. Thanks! index-v3-3 (1).html

Hey folks, I found this Codpen and would love to achieve this in React using Hooks, but having a little problem. Does anyone have this sample in React Hooks?

I'm building a landing page using React Router that has a scrolling menu. Based on the position of the scrolling menu, the background elements change. Everything works, until I navigate to a different page, and receive Uncaught TypeError: Cannot read property 'classList' of null. When I return to the landing page, the ScrollTrigger is broken until the site is refreshed. I know this is due to the component unmounting and ScrollTrigger not being able to find the elements triggering onLeave and onLeaveBack. I tried using useLocation() to make sure ScrollTrigger instantiate when the the pathname = "/" and otherwise kill() the trigger, but it didn't solve the issue. So the question is, how do I navigate away from my landing page without having my ScrollTrigger break and require a full refresh? Here is the structure of my ScrollTrigger: const pages = ["radio", "shop", "music", "about", "news"]; useEffect(() => { const backgroundSquare = document.querySelector(".home-menu-background"); pages.forEach((page) => { gsap.to(`#home-menu-item-${page}`, { scrollTrigger: { trigger: `#home-menu-item-${page}`, start: "top center", end: "bottom center", onEnter: () => { backgroundSquare.style.backgroundImage = `url("${backgroundImages[page]}")`; document.querySelector(`#home-menu-item-${page}`).classList.add("active"); }, onEnterBack: () => { backgroundSquare.style.backgroundImage = `url("${backgroundImages[page]}")`; document.querySelector(`#home-menu-item-${page}`).classList.add("active"); }, onLeave: () => { document.querySelector(`#home-menu-item-${page}`).classList.remove("active"); }, onLeaveBack: () => { document.querySelector(`#home-menu-item-${page}`).classList.remove("active"); }, }, }); }); });

So I'm curious if there is any good tutorials out there on how to use React Hooks with GSAP What I'm looking to do is most likely use some useEffect hooks to have an animated transition in and then a transition out. If there are no existing resources on this for me to read up on then I'll look to post my code in here once I'm to that point.

Hi guys, I just want to contribute with my findings in case others ran into this. I had been struggling getting GSAP's Draggable to work with Next.js and have finally found a solution. Next.js does Server Side Rendering (SSR) so pages rendered on the server had issues loading the GSAP NPM modules. Please note that pages worked just fine client-side. ERROR: import TweenLite, { _gsScope, globals, EventDispatcher } from "./TweenLite.js"; ^^^^^^ SyntaxError: Unexpected token import To resolve the issue with GSAP not being transpiled, I installed next-plugin-transpile-modules npm install --save next-plugin-transpile-modules Then I modified/created my next.config.js file according to their instructions on their NPM page. https://www.npmjs.com/package/next-plugin-transpile-modules Draggable finally worked after that (only if throwProps was set to false and you did not import ThrowPropsPlugin). However, if using a plugin like ThrowPropsPlugin.js it would display an error message like: TypeError: Cannot read property 'defaultView' of undefined Around line 515 of the ThrowPropsPlugin.js file, I changed it: //FROM THIS: _doc = _gsScope.document, //TO THIS LINE I FOUND IN DRAGGABLE: _doc = _gsScope.document || {createElement: function() {return _dummyElement;}}, After that, I just did "npm run dev" and the pages rendered on the server side were fully functional as expected. Hopefully this helps somebody out! Guys at GSAP, is there any harm in changing that line in the ThrowPropsPlugin? If not, would it be a good idea to update the plugin and other plugins for others who purchased the membership with GSAP so they don't run into this issue that I encountered?

Hello guys. Please help me with some strange behavior. I have parent component (React) where i initialize ScrollTrigger.scrollerProxy with Locomotive Scroll as you recommended in docs (scrollerProxy). If i try to use scrollTrigger inside that parent component (using useEffect) - everything works fine. But if i use scrollTrigger inside child component and provide the same scroller element (with id #smooth-scroll) then i have an issue. I've already tried: to call ScrollTrigger.refresh() inside child component; make reference (useRef) to locomotive instance in parent component and pass it to child via props; make reference to scroller element using useRef inside parent and pass it to child via props; to initialize ScrollTrigger.scrollerProxy with Locomotive Scroll inside child component - this works, but if i have bunch of elements which calling this initialization - i have terrible performance issue. So i think the best way is to provide only one initialization inside parent (i.e. page) and pass it somehow to child components. Link to Codesandbox (to see smooth scrolling click "Open in new window" icon at top right in browser panel). Maybe someone else have the same problem? What i do wrong in this case?

I used gsap.fromto animate a component when it is rendered through a conditional statement something like below: const [openComponent, setOpenComponent] = useState(false); <button onClick={_=>setOpenComponent(true)}>Open</button> return {openComponent && <Component/>} and in the Component.jsI used useEffectto render the animation useEffect(_ => { gsap.set(ref.current, { y: 0 }); gsap.from(ref.current, { y: "-100%", duration: 0.5, ease: "expo.out", }); }, []); However, the Componentsometimes rendered in its original position (y=0) before starting the animation. It means you will see a flick of the component before the animation starts. When I changed useEffectto useLayoutEffect, it doesn't happen. I have another component called Loading which uses a similar logic as above and the flick doesn't happen. I went through the forum and found this post It is true that the Component has a React.fragment (Loading doesn't have React.fragment)but when I removed it, the flick still happens unless I use useLayoutEffect. Another difference of the Loading from the Component is that Loading is less complicated. Component structure: <div> <div> <div> <p></p> <div> <span></span> <span></span> </div> </div> <div> <p></p> </div> <div> <p></p> </div> </div> </div> Loading structure: <div> <img/> </div> Here is a video example (Ignore the watermark😅) issue-2_sMe3OB4K_Skcz.mp4 I am not familiar with codepen or any other online editors to code a React in it and make an example. Sorry for the inconvenience. 😁😅

Hi there, I am running into an odd issue with my React site and using GSAP. Website: https://gpstaging.netlify.app For all the scroll based triggers, if I resize the window they will either disappear https://take.ms/6VGoD or not fire their animation when scrolling down the page. It looks like they disappear because an inline style of opacity: 0 and visibility: none is getting applied to them. But I have no idea why and even when I removed all the other components that had GSAP animation applied, the styles keep showing up. Here is a simplified demonstration of the items disappearing once the window get's resized a few times. https://codesandbox.io/s/festive-feistel-puiib?file=/src/App.js For the full production code version, please see the below Github link. https://github.com/GedalyaKrycer/gedalyakrycer.github.io/blob/gsapBackup/gk-portfolio/src/components/Bio/index.js I suspect I am not using the useRef correctly and maybe there is issues with having multiple components that have GSAP on it. But I am not sure how to troubleshoot it. Much appreciation for any insight. Gedalya

Hello! I hope you guys are doing good. I have a question about Horizontal scrolling in react. I have attached my code pen to illustrate my issue. I created a ref for the timeline and then an array of refs to attached to the panels to emulate the document.querySelector(".portfolio") variable as seen in this CodePen and since i cannot set overflow-x: hidden to my body, I made a page wrapper that does that. However, the horizontal scrolling does not work but other animated element like the image fading in and the parallax effect of the title works. What am I doing wrong and what can i do? Thank you guys so much for all your help now and in the past! Here is my CodeSandbox

Hey GSAP Community. UPDATE: I have included the CodeSandbox below in a reply thanks to the great tip from Rodrigo that I can import it So the goal...to have the words PROJECTS and WRITINGS scroll from right side of page to left side of page fairly slowly on the scroll down. I also would like the word/heading to be pinned at the top ideally until the next section (writings) comes into view, then it will scroll up and probably even fade out. And then WRITINGS will scroll across as we're scrolling down and get pinned too for a short time or until the CONTACT div pops up into view or something. Both scrolling words will act the same. The issue. So I got the Projects heading to work as intended more or less, but I tried copying it over to the Writings header, thinking it would be the same, but it just keeps playing up and moving/skipping around and I have noooo idea why. I can't get it to be contained in the 'blue' blogs container. Any and all tips are welcome as well. Respective files and code to look into. ProjectList.js in src -> components -> projects BlogsList in src -> components -> blogs Let me know if people need more info to go on. It Thanks in advance. Simon

Hi everyone, First time poster. I see that a Codepen is highly recommended, I am just not sure how to create this react app in Codepen. I will have to look into how to do this next. So. I have been trying to find the solution on the forums to no avail. I can get my animation to play once, but it won't reverse, and it won't play again and I am not sure why. This is the first time using GSAP and timelineLite. What I want to happen is the firstname, lastname and whoButton will zoom off the page, displaying a card with some aboutMe text. Then there is an 'OK' button on that card, which I want to then have the card dissapear (that's working) and then the text to zoom back in to its original position. Does someone mind explaining where my lack of understanding is coming in sorry. Cheers. Simon EDIT: THIS CODE BELOW HAS NOW BEEN UPDATED IN THE SANDBOX LINK PROVIDED IN MY REPLY. const tl = useRef(); // this handles my aboutMe text showing up or not (working) const [showText, setShowText] = useState(false) // this handles my profile photo moving (working) const [animation, setAnimation] = useState(null) // this handles my firstname/lastname/whoButton moving (not-working) const [textAnimation, setTextAnimation] = useState(tl.current = new TimelineLite({ paused: true })) // this goes with the code above (not-working) const [toggle, setToggle] = useState(false); // getting the references of the objects I want to move const profImg = useRef(null); const nameTextFirst = useRef(null); const nameTextSecond = useRef(null); const whoButton = useRef(null); useEffect(() => { // this animation is working setAnimation( TweenMax.to(profImg.current, 1, {y: '20%'}).pause() ) // this animation is not setTextAnimation( tl.current .to(nameTextFirst.current, 0.5, {x: '200%'}) .to(nameTextSecond.current, 0.5, {x: '200%', delay: -0.3}) .to(whoButton.current, 0.5, {x: '200%', delay: -0.15}) ) }, []) function hideAboutMeText() { setShowText(false) animation.reverse() //not working below textAnimation.reverse() } function showAboutMe() { animation.play() //not working below textAnimation.play() // working below setTimeout(() => { setShowText(true) }, 1000); } // not working useEffect(() => { tl.current.reversed(!tl.current.reversed()); }, [toggle]); // not working const toggleTimeline = () => { setToggle(!toggle); };
