  1. I have been trying to code https://codepen.io/GreenSock/pen/bGaWjpw this into my react component using the useGsap Hook as suggested by the docs, but I am not quite sure about how to use it? Please correct me if i am going wrong! Need Help! import './gsap.css' import gsap from 'gsap'; import { useGSAP } from '@gsap/react'; import { ScrollSmoother, SplitText } from 'gsap/all'; gsap.registerPlugin(useGSAP); const Gsapeffect = () => { useGSAP(() => { const smoother = ScrollSmoother.create({ wrapper: "#wrapper", content: "#content", smooth: 1, normalizeScroll: true, ignoreMobileResize: true, effects: true, preventDefault: true, }); gsap.set(".heading", { yPercent: -150, opacity: 1, }); let tl = gsap.timeline(); let mySplitText = new SplitText("#split-stagger", { type: "words,chars" }); let chars = mySplitText.chars; chars.forEach((char, i) => { smoother.effects(char, { speed: 1, lag: (i + 1) * 0.1 }); }); }, []); return ( <> <div id="wrapper"> <section id="content"> <div className="heading" aria-hidden="true"> <p>smooooth</p> <div className="text-container"> <p>scrolling</p> <p data-speed="0.95">scrolling</p> <p data-speed="0.9">scrolling</p> <p data-speed="0.85">scrolling</p> <p data-speed="0.8">scrolling</p> <p data-speed="0.75">scrolling</p> <p data-speed="0.7">scrolling</p> </div> </div> <section className="image-grid container"> <div className="image_cont" data-speed="1"> <img data-speed="auto" src="https://images.unsplash.com/photo-1556856425-366d6618905d?ixid=MnwxMjA3fDB8MHxzZWFyY2h8MTV8fG5lb258ZW58MHx8MHx8&ixlib=rb-1.2.1&auto=format&fit=crop&w=400&q=60" alt="" /> </div> <div className="image_cont" data-speed="1.7"> <img data-speed="auto" src="https://images.unsplash.com/photo-1520271348391-049dd132bb7c?ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&ixlib=rb-1.2.1&auto=format&fit=crop&w=400&q=80" alt="" /> </div> <div className="image_cont" data-speed="1.5"> <img data-speed="auto" src="https://images.unsplash.com/photo-1609166214994-502d326bafee?ixid=MnwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8&ixlib=rb-1.2.1&auto=format&fit=crop&w=400&q=80" alt="" /> </div> </section> <section className="title container flow--lg"> <h1> <span className="eyebrow" aria-hidden="true"> with{" "} </span> GSAP scrollsmoother </h1> <p> Seamlessly integrated with GSAP and ScrollTrigger.

  2. Hello, I have a component that needs to be pinned only when the user is scrolling down. In other words, while the user is scrolling down, a selected div will pin (position: fixed) and space will be added as needed. As the user scrolls up, the selected div is no longer pinned, no additional space is added, and it will not animate. To do this, I was hoping there was a way to conditionally toggle the ScrollTrigger `pin` property based on self.direction, but it does not seem as straight-forward as that (perhaps due to how scroll trigger refreshes). Based on the code below is there anyway to achieve this? DEMO PEN: https://react-1dnq5j.stackblitz.io or https://stackblitz.com/edit/react-1dnq5j?file=src%2Fapp.js
  3. const DotCursor: React.FC = () => { const dotRef = useRef<HTMLDivElement>(null); const { clientX, clientY } = useMousePosition(); const [isVisible, setIsVisible] = useState(false); const handleMouseEnter = () => { setIsVisible(true); }; const handleMouseLeave = () => { setIsVisible(false); }; const handleMouseMove = () => { setIsVisible(true); }; useGSAP( () => { const dot = dotRef.current; if (!dot) return; window.addEventListener("mousemove", handleMouseMove); document.addEventListener("mouseenter", handleMouseEnter); document.addEventListener("mouseleave", handleMouseLeave); const animateDot = () => { gsap.set(dot, { x: clientX, y: clientY, }); }; gsap.ticker.add(animateDot); return () => { window.removeEventListener("mousemove", handleMouseMove); document.removeEventListener("mouseenter", handleMouseEnter); document.removeEventListener("mouseleave", handleMouseLeave); gsap.ticker.remove(animateDot); }; }, { dependencies: [clientX, clientY] } ); return ( <div ref={dotRef} className="dot-cursor bg-orange-700" style={{ opacity: isVisible ? 1 : 0, position: "fixed", width: "10px", height: "10px", border: "solid 1px black", borderRadius: "20%", pointerEvents: "none", transform: "translate(-50%, -50%)", zIndex: 9999, }} /> ); }; export default DotCursor;
  4. Hello, For my final university college project I want to create a "Your own adventure webcomic". I've recently started my React journey, and I wanted to animate some stuffs in this project. Here you can access a codesandbox for a better understanding for what is coming. I think that I have a misunderstanding of how the scope of useGsap works. Here is my problem, I have a parent component (StoryNarrative) and its child (StoryFragment). StoryNarrative create multiple iteration of StoryFragment. It is important to also note that a new StoryFragment is created whenever the state displayToNumber changes. displayToNumber is a number that changes everytime that the user clicks on a button. It tells StoryNarrative to loop StoryFragment based on an array from 0 to displayToNumber. I want the scope to be a div within the last iteration of StoryFragment that has been created. In order to do so, I have created a ref array (animatedRef) that refers every div. Once done, I have written that the scope should be the last element created. I thought that I could have two different ways to do so. Use animatedRef.current[animatedRef.current.length - 1] or animatedRef.current.[displayToNumber]. But it does not work as I thought. The console shows that for some reason, even after that a new div is created, React keeps using the old length for the first build of the component before changing when I use "animatedRef.current[animatedRef.current.length - 1]" but it does not do so when I use animatedRef.current.[displayToNumber]. But the problem is, however I write animatedRef.current.[displayToNumber] or animatedRef.current[animatedRef.current.length - 1] as the scope, it never refers to the last element created. With animatedRef.current[animatedRef.current.length - 1] it animates the element before the last and with animatedRef.current.[displayToNumber] it seems like the scope does not work at all. So if anyone have any idea of why this is happening please let me know. English is not my mothertongue so I may have done some mistakes, if something is not clear enough please let me know. And thanks in advance for your answers.
  5. I'm using the new useGSAP hook with gsap + scroll trigger. When I use the hook, my scrolltrigger pinned section seems to disappear. When I use the original way (using useIsomorphicLayoutEffect with GSAP Context) it seems to work exactly as expected. Im using packages: - GSAP business - useGSAP version 2.1.1. - React version 18.3.1 - React DOM version 18.3.1 Unfortunatley when I create a minimal demo, both methods work fine Is there something I should be looking for, or am i not using the hook correctly? See video here for example => https://vimeo.com/947131601?share=copy // this works useIsomorphicLayoutEffect(() => { const ctx = gsap.context(() => { gsap.to("#voting", { scrollTrigger: { trigger: "#voting", pin: "#voting", start: "top top", end: "bottom top", }, }); }); return () => ctx.revert(); }, []); // this does not work useGSAP(() => { gsap.to("#voting", { scrollTrigger: { trigger: "#voting", pin: "#voting", start: "top top", end: "bottom top", }, }); }, []);

  8. I'm just starting out with React and `useGSAP` and I'm running into an issue with out what appears to be the hook registering: react.development.js:1630 Uncaught TypeError: Cannot read properties of null (reading 'useRef') at useRef (react.development.js:1630:1) at useGSAP (index.js:32:1) However, despite this error - I can console.log the `useGSAP` hook, and also the `gsap` package and both are successfully loaded. This error message happens when I try to use useGSAP. This is the error message i'm getting: Segment.tsx:39 Warning: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons: 1. You might have mismatching versions of React and the renderer (such as React DOM) 2. You might be breaking the Rules of Hooks 3. You might have more than one copy of React in the same app See https://reactjs.org/link/invalid-hook-call for tips about how to debug and fix this problem. printWarning @ react.development.js:209 error @ react.development.js:183 resolveDispatcher @ react.development.js:1592 useRef @ react.development.js:1629 useGSAP @ index.js:32 (anonymous) @ Segment.tsx:39 react.development.js:1630 Uncaught TypeError: Cannot read properties of null (reading 'useRef') at useRef (react.development.js:1630:1) at useGSAP (index.js:32:1) at Segment.tsx:39:1 at renderWithHooks (react-dom.development.js:16305:1) at updateForwardRef (react-dom.development.js:19226:1) at beginWork (react-dom.development.js:21636:1) at HTMLUnknownElement.callCallback (react-dom.development.js:4164:1) at Object.invokeGuardedCallbackDev (react-dom.development.js:4213:1) at invokeGuardedCallback (react-dom.development.js:4277:1) at beginWork$1 (react-dom.development.js:27451:1) here's what i have so far: import React, { forwardRef, useEffect, useCallback, useRef } from "react"; import { useActiveSegment, BkExpeditionContextValues, } from "src/BkExpedition/index"; import { mergeRefs } from "src/util/mergRefs"; import clsx from "clsx"; import gsap from "gsap/dist/gsap"; import { useGSAP } from "@gsap/react"; gsap.registerPlugin(useGSAP); export type SegmentProps = Omit< React.ComponentPropsWithoutRef<"section">, "onAnimationStart" | "onDragStart" | "onDragEnd" | "onDrag" | "onDragOver" > & { segmentKey: BkExpeditionContextValues["activeSegment"]; }; export const Segment = forwardRef<HTMLDivElement, SegmentProps>( (props, ref) => { const { segmentKey, className, children, ...restOfHtmlAttrs } = props; const { activeSegment, previousSegment } = useActiveSegment(); const isActive = activeSegment === segmentKey; const sectionRef = useRef<HTMLDivElement>(null); const animateInTL = useRef<gsap.core.Timeline>(); const animateOutTL = useRef<gsap.core.Timeline>(); useGSAP(() => { // console.log("sectionRef", sectionRef.current); // if (sectionRef.current === null) return; // // animateInTL.current = gsap // .timeline({ paused: true }) // .fromTo(sectionRef?.current, { x: "100%" }, { x: "0%" }); // animateOutTL.current = gsap // .timeline({ paused: true }) // .fromTo(sectionRef?.current, { x: "0%" }, { x: "-100%" }); }); useEffect(() => { if (previousSegment === null) { return; } if (activeSegment === segmentKey) { animateInTL?.current?.play(); return; } if (previousSegment === segmentKey) { animateOutTL?.current?.play(); return; } }, [activeSegment, previousSegment, segmentKey]); return ( <section ref={mergeRefs(ref, sectionRef)} {...restOfHtmlAttrs} aria-hidden={!isActive} className={clsx(className, styles.segment, isActive && styles.isActive)} style={{ transform: isActive ?

  9. Hi everyone. I'd like to create an animation that plays in a loop and also plays when I scroll. Animation: animates the css clip-path property of the images according to the current index. Currently, when the component is mounted, the animation plays correctly but remains stuck on the last image of the array. And when I scroll, nothing happens. Does anyone have a solution or know where to find the bug ? Thank you in advance Demo link : https://stackblitz.com/edit/gsap-react-basic-f48716-ebgh4d?file=src%2FApp.js I was inspired by the following examples: https://codepen.io/GreenSock/pen/wvZjeGN?editors=1010 https://codepen.io/GreenSock/pen/XWzRraJ?editors=1010
  10. Hello! I encountered a problem when I was using the useGSAP hook for React, scrollTrigger, and content with dynamic height. The situation is as follows: somewhere on the page, we have a component with dynamic height, in this particular case we have tabs with their own content. Just below, there are expanding accordions. The height of the content in the tabs and accordions can vary. Further down the page, there is a block with GSAP animations (there will be several of them), which uses the React useGSAP hook. I have encountered 2 problems. The first problem is that, for example, the block with animation is not updated while opening an accordion. This can be clearly seen in this example - it contains the necessary minimum to see the error. When clicking on the accordion toggler, the animation start label remains in the same place. When scrolling to it with the accordion open, the animation fails. https://codepen.io/tis-cake/pen/OJGxdVG The second issue is related to passing dependencies into the useGSAP hook. If I understand correctly, one of the solutions to my problem is to pass the height of, for instance, the body tag as a dependency. When the accordion is expanded, the height of the body changes - and at this stage, do I need to update the animation? When passing this value into the dependencies array, the animation fails even with the accordion closed. Would u mind helping me with the understanding of the direction in order to solve this problem? I'm convinced I'm doing something wrong?
  11. Hi everyone, I'm experiencing an issue with my animation. I've searched through existing topics, but couldn't find a solution that matches my problem. To provide some context, I've created a dynamic page for displaying project details. It consists of a description section on the left and an image section on the right. The description is scrollable, and the image changes based on the current description. The issue like i start from project/1 i show all there descriptions all good but when i go to the project/2 or project/^n the scroll still in the register or some where that affect to my animation (the scroll affect to the first image because the scroll still ) ,However, everything works fine if I refresh the page like what i want , So, I'm looking for a solution to reset the ScrollTrigger and resizing functionality dynamically. (methods or props in the useGSAP) Thanks for your help, and I apologize for the lengthy explanation. I just wanted to ensure the context is clear. gsap.registerPlugin(ScrollTrigger); const workInfoItemsRef = useRef(); let imageRefs = useRef([]); const ParrentRef = useRef(); useGSAP( () => { // initialise the imageRefs if ( workInfoItemsRef.current && imageRefs.current.length > 0 && NumberOfFeature > 1 ) { // N2aficti ZIndex directly lrefs: imageRefs.current.forEach((item, index) => { item.style.zIndex = imageRefs.current.length - index; }); // nInitialiser clip-path b refs: gsap.set(imageRefs.current, { clipPath: function () { return "inset(0px)"; }, }); // nCriyi l'animation : const animation = gsap.to( imageRefs.current, // fiha ta last child ! rd lball { clipPath: function (i) { return i != imageRefs.current.length - 1 ? "inset(0px 0px 100% 0px)" : "inset(0px)"; }, stagger: 2, ease: "none", } ); // nCriyi ScrollTrigger l Parrent ref: ScrollTrigger.create({ trigger: ParrentRef.current, start: "top bottom", // markers:true, animation: animation, scrub: 1, }); } }, { dependencies: [CurrentProject], scope: ParrentRef, revertOnUpdate: true } );
  12. Hello dear GSAP community. I face a challenge, trying to use "useGSAP" hook and define one reference to main element as scope. I would like to call functions from useGSAP hook but... i still want to respect scope for element selectors. When i target any element to perform .to(), i would like to search that element inside my scope. Currently i feel like i am breaking the code with given approach and once i call functions outside useGSAP then scope is also lost. Can someone aid me with this logic to make right decisions. Thank you to all great professionals out there ? const Home = () => { const mainRef = useRef(null); ... // example of usage const func1 = (tl: Timeline, mainRef: MainRefType) => { const homeIntroSubTitle = `${mainRef.current} .home__intro h2`; const homeIntroButton = `${mainRef.current} .home__intro-button`; const homeFeatureItem = `${mainRef.current} .home__feature-item`; gsap.set([homeIntroSubTitle, homeIntroButton, homeFeatureItem], { y: -10, opacity: 0 }); tl.to(homeIntroSubTitle, { y: 0, opacity: 1, duration: 1 }, 0); tl.to(homeIntroButton, { y: 0, opacity: 1, duration: 1 }, 0); tl.to(homeFeatureItem, { y: 0, opacity: 1, duration: 1, stagger: 0.3 }, 0); } useGSAP(() => { const tl = gsap.timeline(); func1(tl, mainRef); func2(mainRef); func3(mainRef); }, { scope: mainRef }); return ( <main className='home' ref={mainRef}> ... ) }
  13. Hello! I think I got trouble understanding how should I use GSAP in my Next.js project, in particular, ScrollTriggers, how to initialize and kill them on resize and pathname change. Let me share you my component (it's a Prismic slice in case you wonder about the syntax). I removed some parts which are irrelevant. The aim of this code is to pin the smaller "intro" div, until we scroll through the whole container. Then it sticks to the bottom of it. This code actually works, but I've got a couple problems with it. 1. Resizing works really slow. It feels like a lot of stuff is happening in the background and it feels wrong. But it still kinda works. 2. Second issue is major and it's blocking me from going further. The line that kills ScrollTriggers applies to all the ScrollTriggers across the projects, including those from other components! How should I set it up properly? I will appreciate any advice! 'use client'; import { useRef } from 'react'; import gsap from 'gsap'; import ScrollTrigger from 'gsap/dist/ScrollTrigger'; import { useGSAP } from '@gsap/react'; const Values = ({ slice }: ValuesProps): JSX.Element => { const container = useRef<HTMLDivElement>(null); const intro = useRef<HTMLDivElement>(null); const setupSTs = (offset: number) => { // I don't need a pin on mobile screens <= 768 if (window.innerWidth > 768) { ScrollTrigger.create({ trigger: container.current, start: 'top top', end: `bottom bottom-=${offset}`, pin: intro.current, }); } }; const initSTs = () => { // This line breaks my other components, but if I disable it, resizing for this component doesn't work anymore ScrollTrigger.getAll().forEach((ST) => ST.kill()); if (intro.current) { let introHeight = intro.current.clientHeight; let offset = window.innerHeight - introHeight; setupSTs(offset); } }; // Is it a correct use of useGSAP? useGSAP( () => { gsap.registerPlugin(ScrollTrigger); initSTs(); ScrollTrigger.addEventListener('refreshInit', initSTs); }, { scope: container } ); return ( <section ref={container} > <div className={styles.values__wrapper}> <div ref={intro} className={styles.values__intro}> (...) </div> <div className={styles.values__container}> (...) </div> </div> </section> ); }; export default Values;
  14. I'm new to GSAP and try to use it with Next.js (React.js). I understand Tween and Timeline, but still can't get my head around Flip. I want to make Grid item view just like the example, but with useGSAP in React. I still can't make it flip. Is there any similar example I can follow?
  15. Hi all, I'm trying to apply an animation to a certain scope only, using useGSAPs scope option. The weird thing is, on my local react project it only works, if I add ".current" in {scope: ref.current}. Then, however, it also affects elements outside of the scope. If I only write {scope: ref}, the elements outside the scope aren't affected, but neither are the ones inside the scope. I tried recreating the issue in this stackblitz, but here's it's working as intended ?? https://stackblitz.com/edit/react-avrbpg?file=src%2FApp.js Any idea, what I could be doing wrong locally? I checked a million times that the ref is on the right div...
