Hey there, first off: congrats on and even more, thanks for the scrollTrigger Plugin - it's just awesome. I have been using scrollMagic in a project of mine so far, and been re-writing it to use scrollTrigger instead. I love it, since in most cases it is way easier to use and wrap my head around what I need to achieve certain sorts of scroll based animations - great job on that! But I have run into an issue, that probably is rather an edge case, since it is concerning the use of scrollTrigger together with idiotwu' smooth-scrollbar plugin. I know you guys try keeping things in here related to problems related directly to GSAP, but I thought I'd post anyway, since my problem might have something to do with scrollTrigger's performance - not saying it does, though. It's more likely that I am doing something wrong here, I guess. So, I have sections that are being pinned and their contents transformed on the x-axis to make them appear horizontally scrolling. I found, that hooking scrollTrigger up to smooth-scrollbar works in just the same way as it works with scrollMagic; by adding a listener to smooth-scrollbar that refreshes scrollTrigger on the virtual scrolling of smooth-scrollbar. In my project, when I have only one section with that effect, everything runs buttery smooth, but as soon as there is more than one section with the trigger applied, the scrolling suffers drops in fps to below 50 - which makes it pretty much visibly laggy and sort of annoying. I made a pen with a total of 5 horizontal sections, to show, what I mean. https://codepen.io/akapowl/pen/7c21be9a241e0e13b98316c197b617ef This is not the case with scrollMagic - everything staying smooth there. https://codepen.io/akapowl/pen/074d0a380e2a0393b13d0fb57b5be166 So, now I am wondering: Since, if I understood correctly, scrollTrigger makes all the heavy requests on refresh, is it not a good idea, to hook the refresh to the virtual scroll? scrollMagic seems to handle it absolutely fine, so might this be something, scrollTrigger could be improved on? Or am I maybe doing something totally wrong here? Maybe somebody finds the time to look into this. Any input appreciated. Cheers Paul

I'm creating a project where i need smooth scrolling as well as scroll-to function. In my codepen I've used smooth-scrollbar library coexisting with scrolltrigger's scrollerproxy() library... which works fine. But due to the scrolljaking the scrolltoplugin is not working properly. I've tried scrolltoplugin without smooth scrolling it works but I need both to work together. Is there any way to make them work together? Thanks in advance!

Hello, Is it possible to apply ScrollTrigger.scrollerProxy() on body tag? I've tried to use this: https://codepen.io/GreenSock/pen/oNLqgBm with body tag as a selector for scroller, and it didn't work. Is there any example? Thanks!

Hello..! I did setup locomotive scroll with GSAP for my Wordpress Site. Currently it is running beautifully..! But the problm is that, None of my Elementor Scroll Animations are working. I am pretty new to Wordpress and Web Development. If you can help me, it would be a great pleasure. (Iam using Astra theme + Elementor Pro. I created some scroll animations for couple of Elementor sections. Everything not working. And I add my page (#page) as the locomotive scroll element.)

It appears as though the scrollerProxy is initiated multiple times after routing which causes the matrix 3d animation to jump from -232213 to 0 and back. I think this is because the nuxt instance is kept while routing between pages that also use the _.vue page template but I cant figure out how to force it to forget the past scrollerProxy 😢 Any advice as to how to initiate smoothscrolling in Nuxt? // _.vue template <template> <div> </div> </template> <script> import { gsap } from 'gsap' import { ScrollTrigger } from 'gsap/ScrollTrigger' gsap.registerPlugin(ScrollTrigger) export default { mounted() { this.smooth() this.$forceUpdate() }, destroyed() { // used to kill the ScrollTrigger instance for this component this.expand = false }, methods: { smooth() { if (process.client) { window.scrollTo(0,0) const locoScroll = new this.LocomotiveScroll({ el: document.querySelector('.smooth-scroll'), smooth: true }) // each time Locomotive Scroll updates, tell ScrollTrigger to update too (sync positioning) locoScroll.on('scroll', ScrollTrigger.update) ScrollTrigger.scrollerProxy('.smooth-scroll', { scrollTop(value) { return arguments.length ? locoScroll.scrollTo(value, 0, 0) : locoScroll.scroll.instance.scroll.y }, // we don't have to define a scrollLeft because we're only scrolling vertically. getBoundingClientRect() { return {top: 0, left: 0, width: window.innerWidth, height: window.innerHeight} }, // LocomotiveScroll handles things completely differently on mobile devices - it doesn't even transform the container at all! So to get the correct behavior and avoid jitters, we should pin things with position: fixed on mobile. We sense it by checking to see if there's a transform applied to the container (the LocomotiveScroll-controlled element). pinType: document.querySelector('.smooth-scroll').style.transform ? 'transform' : 'fixed' }) // each time the window updates, we should refresh ScrollTrigger and then update LocomotiveScroll. ScrollTrigger.addEventListener('refresh', () => locoScroll.update()) // after everything is set up, refresh() ScrollTrigger and update LocomotiveScroll because padding may have been added for pinning, etc. ScrollTrigger.refresh() const headerItems = ['.header__logo', '.nav', '.header__trigger'] if (!this.isTouchDevice()) { headerItems.forEach((item) => { gsap.to(item, { scrollTrigger: { trigger: '.header', scroller: '.smooth-scroll', scrub: true, pin: true, start: 'top', end: document.querySelector('body').offsetHeight, pinSpacing: false, }, y: document.querySelector('body').offsetHeight, transformOrigin: 'center top', ease: 'none' }) }) const largeMedia = document.querySelectorAll('.large-media.no-controls') if (largeMedia) { largeMedia.forEach((media) => { let mediaItem = media.querySelector('video') if (media.querySelector('img')) { mediaItem = media.querySelector('img') } gsap.to(mediaItem, { scrollTrigger: { trigger: media, scroller: '.smooth-scroll', scrub: true, start: 'top', end: 'bottom', }, y: '100%', transformOrigin: 'center top', ease: 'none' }) }) } const nextCase = document.querySelector('.next-case') if (nextCase) { gsap.to('.next-case .large-media', { scale: 1, opacity: 0, scrollTrigger: { trigger: nextCase, scroller: '.smooth-scroll', start: `top-=${window.innerHeight / 2}`, end: `bottom-=${window.innerHeight}`, scrub: 1, } }) gsap.to('.next-case__background', { opacity: 1, scrollTrigger: { trigger: nextCase, scroller: '.smooth-scroll', start: `top-=${window.innerHeight / 2}`, end: `bottom-=${window.innerHeight}`, scrub: 1, } }) gsap.to('.large-text-header', { opacity: 1, scrollTrigger: { trigger: nextCase, scroller: '.smooth-scroll', start: `top-=${window.innerHeight / 2}`, end: `bottom-=${window.innerHeight}`, scrub: 1, } }) const observerTrigger = document.querySelector('.next-case__observer-trigger') const onIntersection = (entries) => { for (const entry of entries) { if (entry.isIntersecting) { this.loaded = entry.intersectionRatio if (entry.intersectionRatio > 0.95) { this.background = true if (!this.expand) { // window.location.href = nextCase.querySelector('a').getAttribute('href') // goor, doch effectief this.$router.push(nextCase.querySelector('a').getAttribute('href')) this.expand = true } } } } } let threshold = [] // create array with numbers between 0 and 1 for (var i = 0; i <= 100; i++) { threshold.push(i / 100) } const observer = new IntersectionObserver(onIntersection, { threshold }) observer.observe(observerTrigger) } } } }, isTouchDevice() { try { document.createEvent('TouchEvent') return true } catch (e) { return false } } }, } </script>

Hello, I use a smooth-scrollbar within a project. I can run it with ScrollTrigger with scrollerProxy(). No problem. But it only works with scrub:true. I just can't use it to trigger it. I also used it with locomotive-scroll. The scrub problem is not there. (In codepen if you change scrub:true it will work) https://codepen.io/ozcancelik/pen/WNwJqRj Is this a scrollProxy bug? Or where am I doing wrong? Thank you. Ozcan
