    GSAP 3.4 Released

    GSAP 3.4 has arrived with some significant improvements to ScrollTrigger like: Accommodating different setups for various screen sizes, like a mobile version and desktop version - ScrollTrigger.matchMedia() Batching and staggering elements that enter the viewport, similar to what's often done with IntersectionObserver - ScrollTrigger.batch() Integrating with smooth scrolling libraries - ScrollTrigger.scrollerProxy() ScrollTrigger.matchMedia() You can use standard media queries to seamlessly transition between different ScrollTriggers. It's surprisingly simple to set up and let ScrollTrigger automatically handle all of the creating, undoing, and destroying for you. Basic setup ScrollTrigger.matchMedia({ // desktop "(min-width: 800px)": function() { // setup animations and ScrollTriggers for screens 800px wide or greater (desktop) here... // These ScrollTriggers will be reverted/killed when the media query doesn't match anymore. }, // mobile "(max-width: 799px)": function() { // The ScrollTriggers created inside these functions are segregated and get // reverted/killed when the media query doesn't match anymore. }, // all "all": function() { // ScrollTriggers created here aren't associated with a particular media query, // so they persist. } }); See the Pen ScrollTrigger.matchMedia() Demo by GreenSock (@GreenSock) on CodePen. There's a new ScrollTrigger.saveStyles() method that can be useful with matchMedia(). It saves the current inline styles for any element(s) so that they're reverted properly if animations added other inline styles. It's explained in the video above. See the ScrollTrigger.matchMedia() docs for details. ScrollTrigger.batch() Normally, each ScrollTrigger fires its callbacks (onEnter, onLeave, etc.) immediately when they occur but what if you want to coordinate an animation (like with staggers) of ALL the elements that fired a similar callback around the same time? ScrollTrigger.batch() creates a coordinated group of ScrollTriggers (one for each target element) that batch their callbacks within a certain interval, delivering a neat Array so that you can easily do something like create a staggered animation of all the elements that enter the viewport around the same time. It's a great alternative to IntersectionObserver because it's more widely compatible and easier to work with. Plus you're not restricted to only entering or exiting the viewport - batch() can use ANY start and end values! Demo See the Pen ScrollTrigger.batch() Demo by GreenSock (@GreenSock) on CodePen. See the ScrollTrigger.batch() docs for details. ScrollTrigger.scrollerProxy() ScrollTrigger purposefully avoids "scrolljacking" (disabling the browser's native scrolling behavior in favor of a custom, non-standard scrolling solution). However, smooth scrolling was by far the most requested feature to pair with ScrollTrigger. There are plenty of smooth-scrolling libraries out there, so we created the .scrollerProxy() method to make it simple to integrate any of them with ScrollTrigger (or create your own effects). Here's a basic example using Locomotive Scroll but check out the .scrollerProxy() docs for examples with other libraries. See the Pen ScrollTrigger with LocomotiveScroll by GreenSock (@GreenSock) on CodePen. And more... GSAP 3.4 also delivers various bug fixes, so we'd highly recommend installing the latest version today. There are many ways to get GSAP - see the Installation page for all the options (download, NPM, zip, Github, etc.).

  2. Hi! I'm trying to achive the effect that on scroll down/up GSAP animation will play and change the section content and after it reaches the last section it will display first section content and so on if scroll up on first content it display last content, but the eventListener is added on wheel, because I want to prevent page scroll, and here is the problem. If you scroll while the animation is playing it will display wrong content and if you scroll too many times the incrementation / decrementation will brake the code, so my question is: can I disable mouse wheel on a time when the animation is playing? Tried to use preventDefault() on event, but it didn't work at all. It's this codepen: Codepen Also I'm sorry if the solution is kinda messed up, but this was the only thing that came to my mind. Then after I asked this question on StackOverflow I recived the information that I can use .then(), but the problem is that when i change everything up then there is still a small problem, that if i scroll even few times while the animation is playing, then the animation is played again this many time it detects mouse wheel. Codepen 2. So here is my question. Can i somehow change it up, so it will not animate multiple times and will not break whole code? Sorry for not putting code here, but it is a lot of it. Also I know it's not really a GSAP problem but I think I would recive better solution here. Cheers!
  3. Hey guys. First post here. I'm a graphic design and front-end student out of Zealand, Denmark. We are only learning JQuery at my school, but I am a hard learner, so I am looking for other options. I am currently learning vanilla JS, and randomly found this amazing library. So far everything has been super awesome. I'm facing one issue though. I am animating the height of an image. I added an AddEventListener, as I want the animation to start at a specific point on my site. Basically what I want to do is to animate the photo when it reaches the destination of the position. I have other things attached to the Eventlistener which works as it should. But my image keeps restarting when I scroll. Is there anything I can do to have it animate the height and then stick to that height even when I scroll. I tried adding repeat: 0, and I tried to add an onComplete. I have lots of code that works as it should. So I'll just paste the code I have issues with: function scrollAppear(){ const macbook = document.querySelector("#macbookLight"); const mbPos = macbook.getBoundingClientRect().top; const imagePos = window.innerHeight /1.5; if(mbPos < imagePos){ const tl = gsap.timeline(); tl.fromTo(macbook, 2, {height: 0}, {height: 500}); } } window.addEventListener("scroll",scrollAppear); I'd appreciate any help I can get, I have been searching Google without any luck. Thanks!
  4. I feel like I may be overthinking this... 😬 I have multiple sections on a page, each with their own timeline, all of which are attached to the scrollbar via ScrollTrigger. The trigger for each section is the ID of the section's container, and the timelines start at the top of each container. I'm trying to set up a fixed navigation with anchor links for the user to navigate between these sections. The problem I'm running into is that when you click on a nav link, it scrolls the user to top of the container, which is the start of the timeline. Since the timeline is attached to the scroll bar, the user will then have to scroll to play out the rest of the timeline (which I feel is not always intuitive enough). Is there a way to link to the end of the timeline of a section? I tried putting a hidden element at the end of each section for the anchor link to link to... but that doesn't always play out the whole animation. I also thought about making separate timelines (but I feel like that's too much work for something that probably has an easier solution). Am I missing something?
  5. This is a guest post from one of the best teachers of GSAP, Carl Schooff, also known as SnorklTV. If you're new to GSAP or just looking to learn about the GSAP 3 syntax, his video courses are second to none! I can't tell you how many hundred's of questions I've seen in the GreenSock forums about controlling GSAP animations on scroll. I'm so happy there is finally a genuine GreenSock tool to power the future of scroll-driven animations. Before I get into the specifics, it's worth a moment of time to honor those that got us here. A short history of Scroll-driven Animations John Polacek paved the way in 2013 with Superscrollorama, a jQuery plugin that used GSAP under the hood. Many amazing sites were created with this highly-acclaimed, ground-breaking, and trend-setting tool. In 2014 Jan Paepke took the reins and did a complete re-write and SuperScrollarama became ScrollMagic. ScrollMagic was hugely successful as it offered a slew of new features. Excellent demo files made the tool easy for beginners to understand. Awards sites exploded with many clever effects made with the ScrollMagic and GSAP combo. However, as with many solo-led open source projects, it's popularity created a hefty support burden that couldn't be managed. As issues went unanswered in the ScrollMagic repo, more users found their way to the GreenSock forums asking for support on a product GreenSock didn't create or have any way of fixing. ScrollTrigger is born On June 1st, 2020, GreenSock released ScrollTrigger to a sold out audience via a historic YouTube Premiere. ScrollTrigger was built with a totally fresh perspective on how GreenSock animations should be controlled via scroll. Not only does the API offer more features than it's predecessors, but it has a strong focus on performance which really shines in this "mobile-first" world. And as you can expect with any GreenSock product support is phenomenal. For a full list of features, you'll need to check out GreenSock's ScrollTrigger API Docs, but my job here is to get you up and running quickly... so let's go! Watch the Video This video is from my course GSAP 3 Express. I've got over 6 hours of training and loads of exclusive demos to help you master the GreenSock Animation Platform from the ground up at creativeCodingClub.com As always, I load my videos up with info so that I don't have to write a ton of stuff, but here are some key points. Get ScrollTrigger and GSAP ScrollTrigger is hosted on a CDN along with GSAP. Just use the script tags below to load it into your page. <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.11.3/gsap.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/gsap/3.11.3/ScrollTrigger.min.js"></script> Register ScrollTrigger It's recommended to register ScrollTrigger in your JavaScript to avoid tree-shaking with build tools. gsap.registerPlugin(ScrollTrigger); You can get recent CDN Urls from the GSAP Overview in the docs. For use with npm or more advanced build tools check out the GSAP installation videos. Super Basic Demo with a Single Tween The animation is super slow so that you can see how the animation reacts to entering and leaving the scroller-start and scroller-end positions. See the Pen ScrollTrigger QuickStart by Snorkl.tv (@snorkltv) on CodePen. Control a Timeline with ScrollTrigger See the Pen GreenSock ScrollTrigger Timeline by Snorkl.tv (@snorkltv) on CodePen. GreenSock's Toggle Action Demo In the video I explained how toggleActions work and how important they are. For each toggle event (onEnter, onLeave, onEnterBack, onLeaveBack) you can assign an action (play, pause, restart, reset, resume, complete, reverse, none). You'll assign a toggleAction via a 4-part string like "restart pause resume reverse". The best way to understand how they work is to play with the values in the demos above and study the demo below. See the Pen toggleActions - ScrollTrigger by GreenSock (@GreenSock) on CodePen. I'm hoping these resources help get you up and running quickly. For more inspiration check GreenSock's massive collection of ScrollTrigger Demos. What's next? I've only scratched the surface of what ScrollTrigger can do. I'll definitely be creating more training on this awesome tool. If you need help learning GSAP and want to take your skills to the next level check out my courses at CreativeCodingClub.com.

    ScrollTrigger

    Scroll-driven animations re-invented Animate anything on scroll DOM, CSS, SVG, WebGL, Canvas, whatever. Toggle playback state or scrub through animations Entering or leaving a ScrollTrigger area can make an animation play, pause, resume, reverse, restart, or complete...or you can make the scrollbar can act like a scrubber! Pin elements in place Make an element appear immune to scroll changes while the ScrollTrigger is active. This is surprisingly useful for creating slick effects and keeping your animation in view during the scroll. Insane levels of flexibility ScrollTrigger is a control freak's dream when it comes to choreographing animations, but its rich callback system also lets you accomplish things totally unrelated to animation. Directionally smart ScrollTrigger supports vertical and horizontal scrolling, and lets you check if the last scroll movement was forward or backward, and even tracks velocity! Automatic resizing ScrollTrigger elegantly adjusts to viewport size changes. You can even use function-based start/end values to run custom logic or tap into fancy responsive CSS changes. Maximum performance ScrollTrigger uses all kinds of techniques to maximize performance like throttling updates, pre-calculating intersection points to minimize effort during scroll, leveraging transforms, layerizing elements to utilize the GPU, etc. Integrated with GSAP ScrollTrigger is built on GSAP, the battle-tested standard for JavaScript animation that's used on over 10,000,000 sites worldwide including most award-winning ones.

    Circular menu

    Hi, I've been trying to make a menu like this: https://maxilla.jp/ where the menu is a carousel and moves when you scroll, drag, or click. I'm guessing I have to use scrollmagic for the scrolling part, but I'm kind of lost. I just want to be able to scroll and the next item follows in sort of a circular path, like a carousel without arrows. I'm not expecting any of you to tell me the answer. I'd be more than happy if you just simply point me in the right direction. Thank you all for your time!
  10. Hello, I hope you can help me with this. I am trying to create a custom hook for creating an image parallax using intersectionObserver API. Seems work partially but when I scroll I get this error: backend.js:6 Invalid property y set to 47.666666666666664 Missing plugin? gsap.registerPlugin() My goal: using Y or backgroundPosition from/to everytime the element is visible. import React, { useEffect } from 'react'; import { gsap } from 'gsap/all'; function useImageParallax(imagesParentSelector) { useEffect(() => { const appWrapper = document.querySelector('.app--layout'); const elements = document.querySelectorAll(imagesParentSelector); const scrollHandler = () => { let options = { root: null, }; // parallax effect let observer = new IntersectionObserver(function(entries) { entries.forEach((entry) => { const offset = appWrapper.scrollTop / 3; gsap.to(entry, { y: offset }); }); }, options); for (let elm of elements) { observer.observe(elm); } }; appWrapper.addEventListener('scroll', scrollHandler, { capture: false, passive: true }); return () => { appWrapper.removeEventListener('scroll', scrollHandler, { capture: false, passive: true }); }; }, [gsap]); } export default useImageParallax;
  11. Hi! I'm using the plugin SplitTextJs to create an animation reveal to my titles (you can how I'm doing it in the Codepen). I'm doing this animation on many elements and I want to trigger the animation when the element is in the viewport. With some research I saw that I need to do some loop and a lot of people are doing that with scrollmagic. I was wondering if it's possible to do it without scroll magic. The reason is that I have already many script loaded and I want to have the less script possible to load especially if I'm using it for little things. Thank you
  12. Hello I have to do a airplane that fly vertically left and right whenever the user scrolled, I already did it with Scroll magic and I can't figure how to do it right, i know the problem is on the path it must take full height of my container but i don't know how to do it do you have any idea guys I've been stacked for 2 days Thank you
  13. Hi everyone. Can someone help me with animation like this ? https://miro.medium.com/max/800/1*T7YtwbVBbuhdO5g-FA5zKQ.gif The animation as usually start with delay and t looks wierd :( May be someone can give me advice or example. Thanks.
  14. Hey yall, I'm new to greensock, and I love the library and this forum. This forum has especially been helpful as I practice and learn gsap technique. I have a new project that is supposed to animate a background SVG, and it has the following requirements: The background diagonals are supposed to slowly move downwards, kind of like a parallax effect. It's a big SVG with lines running across it When the user scrolls, it supposed to speed up the parallax progress a little bit with some easing, but continues to progress down the timeline When the user scrolls upwards, its supposed to reverse the tween timeline I've been able to achieve a few things, but the things i'm still having trouble with are Reversing the scroll direction with the scroll event is upwards. Also right now, I have the progress of the scroll animation tied to the height percent of the `window.innerHeight`. but after testing, i don't think this is a good idea. Because the window height percent is not compatible with the progress of the timeline. So i should find another way to progress the timeline.. but i'm not sure what. For reference I used this post to get started, which as been really helpful: If anyone has advice from doing something similar to this, please please let me know. My knowledge is not advanced enough to debug. Thank you Thank you!! PS please excuse the messy code, i'm just trying to get this thing working. Best, Gabriel
  15. Hello, I'm trying to update this @Shaun Gorneau Codepen. First of all I would appreciate some help moving the code from jQuery to plain JavaScript. I'm stucked On the other hand I'm experimenting with this pen trying working with a font-size relative to the window width (example: font-size: 8vw;). Obviously, on window resize it messes up all the programming because it changes the object width. Anyone has a better idea than refreshing the page on window resize with a classy: window.onresize = function(){ location.reload(); } Thanks in advance,
  16. Hello Everyone, I am brand new to animation. I am trying to achieve an affect where when a user scrolls, the image zooms in and fades into the next image. Please see this url as an example of what I am trying to achieve: https://ihatetomatoes.net/demos/zoom-into-image-page-scroll/ That particular demo uses skrollr.js which I started to use but then read that it was deprecated and did not work on a lot of mobile devices. I then started to try and find an alternative library and came across scrollmagic. I have started learning it but I cant seem to find any 'zoom' or 'scale' option for scrollmagic. I then turned to Greensock which has various zoom effects but I want things to zoom only when scrolled, so that brought me back to scrollmagic. I really am just getting so confused as to how I can achieve this effect. Please, if anyone can advise how I can get that 'zoom on scroll' effect when a user scrolls (using either Greensock or Scrollmagic) I'd be so grateful. Thank you.
  17. I'm fairly new to React and fresher with Greensock aminations. Want to achieve vertical scroll effect like https://plasticbcn.com but stuck in middle of transition. please guide or provide some code snippets that include react + gsap scroll animation.
  18. Hi, Please scroll down and then up, in CodePen Pin. When I start scrolling down, animation works perfectly. If I scroll up, animation works reverse but the box does not keep original size and position. How can I fix that? Thanks!
  19. Hi there! I'm very new here. Sorry if I ask dumb questions. I'm trying to create a simple single web page displaying an animation that works exactly like the blue paper (not the white one) animation featured on this website (which is by the way a very beautiful and creative site). But without the text, images only. I'm not trying to rip this website off, the concept is gonna be completely different. I noticed the creator of this website used Tweenlite but for the moment I'm too unexperienced to build it on my own. Anyone here has got a similar Codepen (or whatever) I could use and modify or some useful tricks for a newbie like me? Would be so great! Thank you so much in advance. Cheers from Belgium!
  20. Hi guys I saw this demo in the forum lately: https://codepen.io/PointC/pen/YRzRyM I have a draggable horizontal slider in my current project and I would like to make it also scrollable with snapping. Snapping already works. But I have no idea how to make it also scrollable because I am a newbie in JS. Thank you for any help! Best, Cédric
  21. Hi all, Looking for a hand or some advice if possible. I've created this codepen (below) and it works well enough when you drag the content horizontally but I would also like to be able to scroll with the mouse through the content, very much like the functionality of this website - https://antoni.de/cases/ I'm fairly new to Javascript and certainly GSAP, so any input is much appreciated. Thanks Jon
  22. Hi, I use the Draggable plugin locked on the y axis to manage scrolling in a section. I would like to retrieve the y position of the scrolled element to trigger an event when reaching the end of the scroll area. It's working as follow when the user drag but not when he use the mouse wheel for ex. Draggable.create(Pr, { type: 'scrollTop', ... onDrag: function(e) { type: 'scrollTop', this.update() console.log(this.y) } }) How can I get a unified way to retrieve the y position between the different events, drag, scroll, etc.
  23. Hello everyone at GSAP. Thanks for the great ongoing job. For the past day or two, I've been trying to implement GIaco's full page slider on my react website. This is the link to the original on codepen - What I am trying to do is achieve the exact same thing but with react. So far I have not been able to get anything to work especially because some of the line of code in the codepen example above don't make much sense to me when trying to implement them in react. This is what I have so far - import React, { Component } from 'react'; import { TweenMax, TimelineMax, ScrollToPlugin, CSSPlugin, Expo } from 'gsap/all'; import ReactPageScroller from "react-page-scroller"; import '../../styles/components/home.scss'; import Nav from '../nav/Nav'; const plugins = [ CSSPlugin ]; class Home extends Component { state = { slides: [], animating: true } constructor(props) { super(props); this.Go = this.Go.bind(this) } componentWillMount() { const slide = this.state.slides; const indx = slide.length - 1; const Anim = this.state.animating; for(var i = slide.length; i--;) { slide[i].anim = TweenMax.to(slide[i], 0.7, { yPercent: -100, paused: true }); } document.addEventListener("wheel", this.Go); } Go(e){ var SD=isNaN(e)?e.wheelDelta||-e.detail:e; if(SD>0 && indx>0 ){ if(!Anim){Anim=slide[indx].anim.play(); indx--;} }else if(SD<0 && indx<box.length-1){ if(!Anim||!Anim.isActive()){indx++; Anim=box[indx].anim.reverse();} }; if(isNaN(e))e.preventDefault(); }; render() { return ( <div className="home"> <Nav /> <div className="slide" ref={(slide) => { this.state.slides.push(slide) }}>1</div> <div className="slide" ref={(slide) => { this.state.slides.push(slide) }}>2</div> <div className="slide" ref={(slide) => { this.state.slides.push(slide) }}>3</div> </div> ); } } export default Home; Please, if anyone could spare the time in this busy festive period to help me out, I would be ecstatic. Thanks all and Merry Christmas.
  24. I'm creating a landing page and using GSAP to animate some text according the the user's scroll position. How can I keep the landing page in full view and only start scrolling down the page once the text animation has reached its end?
  25. Hello. thank you for your work. I'm using GSAP with React and ScrollMagic and having troubles with IOS scroll animations. other platforms have great productivity of animations. What am I doing wrong?
