I do not at the moment, but as stated before the issue is with the timeline specifically the onEnter etc events. they cause the reversed to not work

Hey, a quick one. When using the HorizontalLoop / SeamlessLoop (https://gsap.com/docs/v3/HelperFunctions/helpers/seamlessLoop) helper function, the reversed option doesnt change anything. My example code: // ... React useEffect code surrounding this. const logos = logoRefs.map((ref) => ref.current); const loop = horizontalLoop(logos, { reversed: true, // Doesnt work speed: 1, // Works paused: false, // Works repeat: -1, // Works }); const performanceTimeline = gsap.timeline({ scrollTrigger: { trigger: main.current, start: 'top bottom', end: 'bottom top', scrub: true, onEnter: () => loop.play(), onLeave: () => loop.pause(), onEnterBack: () => loop.play(), onLeaveBack: () => loop.pause(), }, }); Im expecting my marquee to animate to the right vs to the left which its currently doing. As im writing this it turns out the timeline causing the reverse to not work - specifically the onEnter etc.Why is this effecting the ability to reverse? Im pausing for performance reasons (offscreen = paused, onScreen = play) Kapture 2024-01-09 at 12.49.53.mp4

How would you trigger the number to animate only when youve scrolled to a specific point?

Hey Rodrigo, the React demo you sent doesnt work - any thought son how to fix?

Interestingly after doing some searching and finding this article: taking the ` ` out and replacing with a span with a set width fixes the marquee issue. Gsap doesnt like white-space it seems.

I have an infinite marquee, that i thought was working, however it jumps at the very end slightly, im not quite sure why im wondering based on the code provided below if theres anything that looks wrong in what im doing? JSX File: const MobileMarquee = ({ client }) => { // NOTE • Refs const main = React.useRef(); const first = React.useRef(); const last = React.useRef(); React.useLayoutEffect(() => { const ctx = gsap.context(() => { // Split characters const split = new SplitText(first.current, { type: "chars", charsClass: "char", }); // Split characters count + timing calculation const charsTotal = split.chars.length; const timingFactor = charsTotal * 0.25; let timeline1 = gsap.timeline(); let timeline2 = gsap.timeline(); timeline1.fromTo( first.current, { xPercent: 0, }, { xPercent: -100, repeat: -1, duration: timingFactor, ease: "none", } ); timeline2.fromTo( last.current, { xPercent: 0, }, { xPercent: -100, repeat: -1, duration: timingFactor, ease: "none", } ); }, main); return () => ctx.revert(); }, []); return ( <Jacket isPaused={isPaused} ref={main}> <div> <ul ref={first}> {words.map(({ word, uid }) => ( <li key={uid} className="el"> {word}&nbsp;–&nbsp; </li> ))} </ul> {/* Dupl */} <ul aria-hidden="true" ref={last}> {words.map(({ word, uid }) => ( <li className="el" key={uid}> {word}&nbsp;–&nbsp; </li> ))} </ul> </div> </Jacket> ); }; CSS/JS: // Imports // ------------ import styled, { css } from "styled-components"; // Exports // ------------ export const Jacket = styled.h1( (props) => css` position: relative; z-index: 3; overflow: hidden; width: 100vw; div { display: flex; width: fit-content; } ul { display: flex; width: fit-content; position: relative; justify-content: flex-start; transform: translateX(0); li { display: flex; align-items: center; font-weight: ${props.theme.font.weight.reg}; font-family: ${props.theme.font.type.heading}; font-size: 6rem; line-height: 1.2; color: ${props.theme.colors.brand.bc4}; user-select: none; white-space: nowrap; } } ` ); Codesandbox Recreation: https://codesandbox.io/s/react-hooks-example-w-clicker-t6yno?file=/src/pages/index.js Kapture 2023-05-25 at 23.24.09.mp4

After a reinstall of NPM today, everything is now working again

The problem here is youre importing splittext, but not from the import library, it seems to work when i create it in codepen with the trial, but not with the import in my react project

Why would i use the trial in my build when i pay for greensock?

Im not sure how to recreate it outside of my react application - where do you usually import SplitText from with the business account?

Without the settimeout splittext puts single words onto different lines for some bizarre reason

Im having to run a settimeout, as for some reason, without it gsap doesnt seem to render any animations

Heres my example code: // Imports // ------------ import React, { useRef, useLayoutEffect } from 'react'; import { gsap } from 'gsap'; import { SplitText } from 'gsap/all'; // Styles // ------------ import { Jacket } from './styles'; // Component // ------------ const ScrollAnimatedText = ({ children }) => { // NOTE • refs const comp = useRef(); // NOTE • Animation useLayoutEffect(() => { let timer; let split; const ctx = gsap.context(() => { timer = setTimeout(() => { const childText = comp.current.firstChild; split = new SplitText(childText, { tag: 'span', type: 'lines,words,chars', linesClass: 'line', }); const lines = comp.current.querySelectorAll('.line'); for (const line of lines) { gsap.to(line, { ease: 'none', opacity: 1, y: `0%`, scrollTrigger: { trigger: line, start: 'top bottom', end: 'top top+=60%', scrub: true, markers: false, }, stagger: { each: 0.08, from: 'start', }, }); } }, 150); }, comp); return () => { clearTimeout(timer); ctx.revert(); }; }, []); return <Jacket ref={comp}>{children}</Jacket>; }; export default React.memo(ScrollAnimatedText);

This doesnt work for me

There is no option for "tag", Chrome is complaining that i cannot have Divs inside a <p> tag, so it need it to be a span

Okay I got it working with this code - but it doesnt make sense why this would work vs the other const Marquee = React.forwardRef((props, ref) => { const first = useRef(); const last = useRef(); useLayoutEffect(() => { const width1 = first.current.offsetWidth; const width2 = first.current.offsetWidth; const timeline1 = gsap.timeline(); const timeline2 = gsap.timeline(); timeline1.fromTo( first.current, { xPercent: 0, }, { xPercent: -100, repeat: -1, repeatRefresh: true, duration: 5, ease: 'none', } ); timeline2.fromTo( last.current, { xPercent: 0, }, { xPercent: -100, repeat: -1, repeatRefresh: true, duration: 5, ease: 'none', } ); }, []); return ( <Jacket isPaused={props.isPaused} ref={ref}> <div> <ul ref={first}> {props.text.map(({ word, uid }) => ( <li key={uid} className='el'> {word}&nbsp;–&nbsp; </li> ))} </ul> {/* Dupl */} <ul aria-hidden='true' ref={last}> {props.text.map(({ word, uid }) => ( <li className='el' key={uid}> {word}&nbsp;–&nbsp; </li> ))} </ul> </div> </Jacket> ); });

Also, even trying to set an amount of repeats has no effect - I tried 3 just to see, but it plays once only, ever.

I have created this React component which should be repeating infinitely, but it only plays once. I feel like im going insane, why is it only playing once?? const Marquee = React.forwardRef((props, ref) => { const first = useRef(); const last = useRef(); useLayoutEffect(() => { const tl = gsap.to(first.current, { xPercent: -100, repeat: -1, duration: 5, ease: 'none', repeatRefresh: true, }); const tl2 = gsap.to(last.current, { xPercent: -100, repeat: -1, duration: 5, ease: 'none', repeatRefresh: true, }); }, []); return ( <Jacket isPaused={props.isPaused} ref={ref}> <div> <ul ref={first}> {props.text.map(({ word, uid }) => ( <li key={uid} className='el'> {word}&nbsp;–&nbsp; </li> ))} </ul> {/* Dupl */} <ul aria-hidden='true' ref={last}> {props.text.map(({ word, uid }) => ( <li className='el' key={uid}> {word}&nbsp;–&nbsp; </li> ))} </ul> </div> </Jacket> ); }); For reference: https://codesandbox.io/s/divine-sun-7kksyk?file=/src/Marquee/index.jsx

I found a fix, instead of using `import { ScrollTrigger } from 'gsap/ScrollTrigger'; ` i used `import { ScrollTrigger } from 'gsap/all'; `

I have a membership but i only get this error when deploying to netlify @Cassie

If youre using scrollsmoother, dont use `scrollY` or `scrollX`. Instead use `x` & `y`.

I just need to figure out how to send this to another component now...

Fixed! I needed to do this instead: // NOTE Before render, calculate smooth scrolling useLayoutEffect(() => { const ctx = gsap.context(() => { smoother.current = ScrollSmoother.create({ smooth: 2, // seconds it takes to "catch up" to native scroll position effects: true, // look for data-speed and data-lag attributes on elements and animate accordingly onUpdate: (self) => { let scrollY = self.scrollTop(); console.log(scrollY); } }); }, main); return () => ctx.revert(); }, []);

I need to access the scroll position. I have a function that looks to when the user scrolls 100px then fires a function, and the same on scroll back up. However ofcourse window doesnt work. How do you access this in ScrollSMoother? Heres my current code, that doesnt work. // NOTE Before render, calculate smooth scrolling useLayoutEffect(() => { const ctx = gsap.context(() => { smoother.current = ScrollSmoother.create({ smooth: 2, // seconds it takes to "catch up" to native scroll position effects: true, // look for data-speed and data-lag attributes on elements and animate accordingly onUpdate: update }); }, main); return () => ctx.revert(); }, []); const update = () => { // Get scrollY position const scrollY = smoother.current.scroll.y; // Scroll doesnt exist console.log(scrollY); };

This is great! Although for my circumstance, i was tweaking the individual values - the example is just copy and paste haha
