  1. Hi, I have an animation that I'm having issues with. I'm trying to reveal a text while also push the logo at the same time (look video reference) but I can't do it smoothly. On my codepen it shows a big jump for the logo image once the text is reveled. Any help on how can I solve this? Screen Recording 2022-06-23 at 15.32.07.mov
  2. Hi there, I am animating a shape towards another shape. However, during the tween there might be a user interaction that changes the target of this animation. In this case I would like to *smoothly* change the ongoing animation so it moves towards the new target. I don't quite understand how to achieve this. When I use separate tweens, then it (obviously) just interrupts the current tween and starts a new one from the current position, which does not look smooth at all (especially with an ease like expo.inOut). In the codepen, when you first click the red target, the circle starts moving towards it. When you now click the blue target, while the circle is still moving, it starts a new tween that moves towards the blue target. I would like to change the setup so that clicking on the blue target continues the current tween, but lets it end at the blue target. Any idea, how to achieve this? Thank you!
  3. Hi there! I would like to add a scalar tween to a component in React using GSAP, the component is a functional component. I've whipped up a quick example of how i think that could be implemented in React using GSAP in the attached codepen. (Type in some number values into the input and watch GSAP tween the number below the input) It's a bit dirty as i need to add a global object to the window on the first mount of the component, so that GSAP has an object it can freely mutate without React resetting it on each render. Is there are better way of allowing GSAP to perform a scalar transition within React? Thanks for any help you can give!
  4. I want to use this parametric waves animation with gsap.min library, currently this is working with TwinMAX. After removing the gsap.min It's working fine but I cant remove gsap.min because other animations or not working without gsap.min I have getting the following error in console. Uncaught TypeError: Sine.easeInOut.getRatio is not a function https://codepen.io/ThiemelJiri/pen/pWyezW Anyone can help please? Thanks
  5. Hello community! I can't figure out how to replay tween after main ScrollTrigger. In the Codepen I have an example, on the first scroll end there is a beam, but if you scroll up again and try to get the same animation (after ScrollTrigger ends), it doesn't replay. I've tried to clear animation inside onComplete like onComplete: () => { circleTl.time(0).kill() } But no luck. How to solve that? Thanks!
  6. Hey guys I have a very weird issue happening. First I was trying to create a CodePen but I can't replicate the issue there. I created a simple code example, so I have a tween on a timeline and I need functionality when the tween starts, the problem is that the onStart() function being trigger twice for some reason. First I thought that my function was being called twice but that is not the case. I did some research and I found similar issues but way back. Since I don't have a codepen to show, this is the example code that I have nextSlide(){ console.log('enter function') gsap.timeline() .to(this.ImageSections[this.currentSection], { onStart: ()=>{ console.log('enter OnStart() Timeline') } }) } And this is the console log. So I can see my function is being trigger once, but the onStart() is being called twice for some reason
  7. Need some help with the infinite looping rocking motion. I would like it to have a smoother transition into a natural back and forth rocking motion.
  8. Hello, sorry if this is a dumb question, I think is more easier that what I'm make it out to be. I have a rada graphic and I need to show multiple colored areas but I need to create a "scale in & scale out" (sorry for the phrase, I don't know exactly how to call this type of animation) animation for every single area, so when I show one I have to scale out before the next one.
  9. 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 !
  10. I don't have a codepen but basically what i want to achieve is this: I have some data loading in the background, and i'm using GSAP3 to create a timeline that's animating an svg infinitly, it's a preload animation basically. What i want to do is that when the data is loaded, i want to pause the current timeline object, animate it until the progress is 1, and then when the animation is completely finished i want to create another animation to smoothly animate the preloader out of the screen and then show the loaded data. I saw an example of this in GSAP2 using TweenMax where: you pass the tweenmax object into the to() method, animate the progress property and then assign a callback function to the onComplete() property to kill the timeline object, but that doesn't seem to work in GSAP3, the svg abruptly jumps to the it's final state (where the progress is equel to 1) instead of animating to it. Can you please tell me how can i achieve this? I can't seem to find any example of this in GSAP3. Thanks in advance!
  11. this.menuTimeLine = gsap.timeline({ paused: true, }); this.menuTimeLine .fromTo(this.ref.menu, { x: "-100%", }, { x: "0%", duration: this.state.open ? 0.3 : 2, ease: this.state.open ? "linear" : "expo.out", }, 0).reverse() if (this.menuTimeLine.reversed()) { this.menuTimeLine.play() } else { this.menuTimeLine.reverse() } Button.addEventListener('click', () => { if (this.menuTimeLine.reversed()) { this.menuTimeLine.play(); } else { this.menuTimeLine.reverse() } }) Update Prop or Tween value conditionally whatever it is normal gsap or gsap timeline In Gsap version 2.x.x updateTo can update tweening values or gsap props but what to do in gsap 3.x.x or Gsap vars can help in this issue ? in Codepen example dynamic ease or duration ? besause timeline is outside of onClick ?
  12. Hi. I'm starting to use this incredible code to have some ads in my page. The issue I'm having is that some banners are located in the middle of the page, so when the user get to that part the animation has already ended. To fix this I'd like to know: - how to start the animation when the <div> section of the banner becomes visible. - If is possible to loop a serie of tweens without timelinelite. Thanks!
  13. Hey! I recently switched from Tween.JS to GSAP, and I'm trying to tween a number with potentially large number of decimal places. I wrote a small library that finds-on-screen and auto-tweens those numbers, so I do not have a *predefined* number of decimals - but as they're cryptocurrency prices, those can be 4, 6, 8 or 9 - usually. I noticed that both TweenMax and TweenLite do only 4 decimals, which is quite weird. Looking around the web (and this forum) I cannot find a solution/parameter/switch how to alter this behavior. Any advice? import gsap from 'gsap'; import { TweenLite, Expo } from 'gsap/all'; gsap.registerPlugin(Expo); export default class TweenEmAll { // ..cut objTween = undefined; objTweenProgress = { value: 0.000001 }; // experiment with pre-defined 6 decimals // ..cut tween() { // ..cut // launch new tween this.objTween = TweenLite.to(this.objTweenProgress, this.duration, { value: this.target, ease: Expo.easeOut, //decimals: 6, // experiment //autoRound: false, // experiment onUpdate: this.onTweenUpdate.bind(this) }); } onTweenUpdate() { // reconstruct value nicely let value = this.objTweenProgress.value.toFixed(6); // experiment // update appropriate element if(this.isInput) this.elmContainer.val(value); else this.elmContainer.html(value); } }
  14. Hello Club Green Sock! I was reading about the common Scroll Trigger mistakes looking for a solution to this question. I think may be going about this the wrong way, but... I have a timeline let hardwareTimeLine = gsap.timeline({ scrollTrigger: { trigger: ".centering-container", scrub: true, pin: true, pinSpacing: true, start: "top", end: "150%" } }); hardwareTimeLine .from(".hero-header", {}) .fromTo(".animated-header", {autoAlpha: 1, top: "29%"}, {autoAlpha: 0, top: "27%"}) .fromTo(".scaling-container", {duration: 1, scaleX: 1.6, scaleY: 1.6, transformOrigin: "50% 50% 0", backgroundPosition: "center"}, {duration: 1, scaleX: .6, scaleY: .6, transformOrigin: "50% 50% 0", backgroundPosition: "center"}, "<") .fromTo(".screen-inner-1", {duration: .5, transform: "translateX(0)"}, {duration: .5, transform: "translateX(-103%)"}) .fromTo(".screen-inner-2", {duration: .5, transform: "translateX(103%)"}, {duration: .5, transform: "translateX(0)"}, "<") .from(".icons-tray", {y: 150, autoAlpha: 0}); and I was wondering if there was a way to put a tween inside the timeline that is attached to the Scroll Trigger at the very end of my last ".from", if that makes sense? I tried .tweenTo() but that didn't seem to give the effect I am searching for. For example (see my codepen, you may need to look it at on full screen) I would like the grey box (".icons-tray") to tween up on it's own and only be started by the scroll trigger. Can anyone point me in the right direction of the way to approach this effect or have a working demo that shows this? Thank you so much!!!
  15. Hey Club Greensock! I was just wondering if I could get some assistance on my project. I have a pretty good base (I think). I just had a couple questions and was wondering if someone might be able to give me some ideas and direction. In my pinned timeline, I have a container that I scale down. I am wondering how might one go about how to decrease the pin spacing as this timeline progresses? As you can see in the image, there is a huge gap due to the scale down. Is there a way to adjust the pinspacing so the final resting place of the animation obeys the global defaults I have setup for the section container? If that makes sense? Specifically if you look at my pen on chrome, there is a weird thing it's doing where there's like a slight margin that is revealing the background slide as it moves. It doesn't do this on FF. Tell me if there is a better way to do this, but basically I have the laptop as a png, the screen area is the transparency, and I have a white bg on the sides of the screen image (to hide the slides) and then I did an overflow: hidden on that laptop png. I know there's got to be a better, more flexible way of doing this. Any suggestions? I would like to setup a global tween (".reveal-up") that I can apply to be flexible to many elements on the page (sort of how like green sock does it here). I have it setup on the header and text in the section with the boxes that rotate and "fly-in". It plays, but it doesn't play when in view, rather it plays at the top of the page. How can I approach this to be more flexible so it plays when in view and also be able to apply it to other elements? Tweening inside my scroll trigger timeline. Specifically I am talking about the text "Lorem Ipsum" that is layerd above the laptop. I know how to make it part of the scroll, but is there a way to trigger it on scroll, but not to play with the scroll? If that makes sense. How would one go about triggering it on scroll, but to play through regardless of the users inputs on the scroll and additionally to reset? I am not sure if this is a thing, but when the browser resizes, there's some funkiness that happens to the timelines. Is there a way that I can make it more flexible on browser resize so the funkiness doesn't happen? Thank you for any help. Here's a couple images to assist in my questions:

    TweenMax

    Note: TweenMax has been deprecated in GSAP 3 in favor of the streamlined gsap object. It has 50+ new features and is almost <strong>half the size!</strong> GSAP 3 is backward compatible with the vast majority of GSAP 2 features including TweenMax. Please see the Migration Guide for details. TweenMax lets you animate literally any property of any object that JavaScript can touch (CSS, SVG, React, Vue, Three.js, canvas, motion paths, generic objects, etc.). Before the release of GSAP 3, TweenMax was the most feature-packed (and popular) animation tool in the GSAP arsenal. However in GSAP 3, you no longer even need to reference TweenMax in your code (although you can because GSAP 3 honors the vast majority of legacy code). We strongly recommend migrating to GSAP 3's streamlined syntax. Quick links Getting started What's so special about GSAP? Documentation: Version 2 | Version 3 Showcase (examples) For convenience and loading efficiency, TweenMax version 2 and earlier included TweenLite, TimelineLite, TimelineMax, CSSPlugin, AttrPlugin, RoundPropsPlugin, BezierPlugin, and EasePack (all in one file). Every bit of that functionality (plus a lot more) is in the GSAP 3 core which is almost half the size. Staggered animations GSAP makes it easy to create staggered animations on multiple objects. The animations can overlap, run in direct sequence or have gaps between their start times. The old TweenMax stagger methods (from version 1 and 2): TweenMax.staggerTo(), TweenMax.staggerFrom() and TweenMax.staggerFromTo() aren't even necessary in GSAP 3 because a "stagger" special property can be added to ANY tween, like in the demo below: Additional Methods (only relevant for version 1 and 2) TweenMax inherits methods from TweenLite and it also has quite a few of its own. ul.chart {width:300px; float:left; margin-right:80px; } ul.chart li:nth-child(1){ font-weight:bold; list-style:none; margin-left:-20px; font-size:20px; margin-bottom:20px; } TweenLite and TweenMax Methods delay() delayedCall() duration() eventCallback from() fromTo() getTweensOf() invalidate() isActive() kill() killDelayedCallsTo() killTweensOf() pause() paused() play() progress() restart() resume() reverse() reversed() seek() set() startTime() time() timeScale() to() totalDuration() totalProgress() totalTime() Methods exclusive to TweenMax getAllTweens() isTweening() killAll() killChildTweensOf() pauseAll() repeat() repeatDelay() resumeAll() staggerFrom() staggerFromTo() staggerTo() updateTo() yoyo() Learn more in the TweenMax version 2 documentation.
  17. Hello First I wanna say I'm fairly new to GSAP and Pixi.js (and JS animations too TBH ). I tried to search for this topic on the forums but couldn't find an answer. So I have this graphics object and I'm trying to animate a simple circle. I'm doing this by tweening its radius and redrawing the circle in the ticker loop. What I don't understand is why the tween starts faster than the ticker itself. This isn't clearly visible on Codepen, but when I run this on a browser the logs start with radius being 30-40px wide. I've read in the docs the tween waits for the 1st tick of the ticker. But it clearly does not. (Or does it? I thought ticker starts when the browser is ready and the 1st animation frame is requested..) I also tried starting the ticker on window.load, but the result is the same. Am I doing something wrong? How can I prevent this without putting a delay into the tween?
  18. Hi there, TL;DR How to prevent the gsap animations to be aborted in react because of a rerender/prop change How to use dynamic props/state inside a gsap tween without beeing interrupted I'm building a spinng wheel with dynamic start- and end-points. You guys already helped me a lot with this: Now I need to implement this into an acutal react application. The biggest problem is, that I use dynamic Properties inside my gsap tweens to calculate e.g. the stop position or when to stop animation. React rerenders my component and aborts the whole animation as soon as a property changes. Of course react should do that - but how to I keep my animation running? What my code should do: start spinning by clicking the "Start Spinning" Button Wheel is spinning infinite Stop wheel by clicking the "Stop Spinning" Button Wheel at least the minimum amount (5) and then stops at the set position What my code actually does: start spinning by clicking the "Start Spinning" Button Wheel is spinning infinite Clicking "Stop Spinning" does not work -> triggers in my local invironment a rerender and aborts the animation in codepen it flickers and then nothing happens (the stop position is never passed into the tween) ... In the codepen it actually does not rerender but the updated prop won't be passed into the tween. const loopAnim = gsap.to(circleRef.current, { rotation: "+=360", ease: "none", duration: 0.5, onComplete: () => { // The props won't update in here... if (loopIteration.current >= fullSpins && typeof stopAt === "number") { stopAnim.play(); } else { loopIteration.current++; loopAnim.play(0); }, paused: true });
  19. Hi guys, how can I get instantiated tween's ease function name? I could do a workaround, but is there a way that is meant to be used :-) ? ...like tween.duration() or *.delay() for duration and delay If an ease is set like a string it can be accessed in tween.vars as string, or I could iterate through all eases functions to find it... is there a way? Also is there a way to get gsap type after instancing...is the tween a "to"," from", "staggerTo"...? Thanks guys, Dario
  20. Hi, Is there any way to achieve this type of animation while scrolling. Im getting confused on the part where when if you scroll down new text-1 appear from bottom and current text-2 exit to up and reverse when scroll back up text-2 appears from top and text-1 exits bottom https://www.apple.com/nz/ipad-pro/ The above is part of the section whereby when you scroll up the content fades down and when you scroll down content fades up Similar to the above website, please kindly help me. Thank You
  21. Hello, I'm doing something in React.js and I don't know why the scrollTo doesn't work. Basically what I'm trying to do is something similar to what Mikel did : https://codepen.io/e1668058/pen/XWbBGPz?editors=0010 but without the buttons. I'm just trying to figure out how to do it just with the mousescroll. just a little extra, I've also thought of adding an onStart and onComplete for the TweenMax so that when it starts I lock the mousewheel with : window.addEventListener("wheel", function(e){e.preventDefault();}, {passive: false} ); and when it completes I unlock the mouse with passive: true. Thank you. Heres my code pen.
  22. I've create a function which scrolls to the next anchor detecting the scroll direction (See below) const CONTAINER_STRING = '#main-container>main', CONTAINER = document.querySelector( CONTAINER_STRING ) let currentChild = 0 gsap.registerPlugin( ScrollToPlugin ) CONTAINER.addEventListener( 'wheel', ( { deltaY } ) => { if ( currentChild < CONTAINER.childElementCount - 1 && deltaY > 0 ) currentChild++ if ( currentChild > 0 && deltaY < 0 ) --currentChild gsap.to( CONTAINER, .5, { scrollTo: '#' + document.querySelector( `${CONTAINER_STRING}>:nth-child(${currentChild + 1})` ).id } ) }, { passive: true } ) My problem is i can't detect if gsap is currently tweening in my page. I've tried some tricks like extract the tween into a variable, but nothing works... 🤔 So how can i detect an interpolation in my page or detect if this specific tween is active ?
  23. Hey, just wanted to share a small fun pin i made today morning with you guys.. Greensock rocks things, and make so easy and smooth the animation, so you can focus on he rest of the codes always, and let Gsap do what he can best. Btw. i read about the pipe() and gsap.quickSetter() which maybe would make things even more smooth here ? Do you think it would make a big different? Feel free to use this and or give feedback if you think things could be done better, smoother, cooler ! Thanks and Happy Tweening to you all !
  24. To implement a smooth scroll I used TweenLite.set{.. within my code. Serving the project works fine without any errors. But as soon as I try to build the project using ng build, it throws following error: How so? import { TweenLite } from 'gsap'; ... TweenLite.set(this.scroller.target, { rotation: 0.01, force3D: true }); "dependencies": { "@angular/animations": "~8.1.2", "@angular/common": "~8.1.2", "@angular/compiler": "~8.1.2", "@angular/core": "~8.1.2", "@angular/fire": "^5.2.3", "@angular/forms": "~8.1.2", "@angular/platform-browser": "~8.1.2", "@angular/platform-browser-dynamic": "~8.1.2", "@angular/router": "~8.1.2", "@types/gsap": "^1.20.2", "bootstrap": "^4.4.1", "firebase": "^7.6.1", "gsap": "^3.1.1", "rxjs": "~6.4.0", "tslib": "^1.9.0", "zone.js": "~0.9.1" }
  25. Is there a way to obtain the current target via the onupdate callback within the fromTo tween in GSAP 3? In GSAP version 2, I was able to do this: this.timeline.staggerFromTo(this._shuffle(this.spheres), 4, { positionY: -1 }, { positionY: 1, repeat: -1, yoyo: true, ease: Power1.easeInOut, onUpdate: function onUpdate(a) { a.target.mesh.position.y = a.target.meshInitPosY + (a.target.positionY + 1) * 200; a.target.mesh.rotation.y = a.target.meshInitRotY + (a.target.positionY + 1) * 3; }, onUpdateParams: ["{self}"] }, '0.01'); However, in GSAP 3, all I get is an array of all of the targets and I need to get the actual target... this.timeline.fromTo(this._shuffle(this.spheres), { positionY: -1 }, { duration: 4, positionY: 1, repeat: -1, yoyo: true, ease: Power1.easeInOut, stagger: 0.01, onUpdate() { console.log(this, this._targets); // this returns all of the spheres //this.target.mesh.position.y = this.target.meshInitPosY + (this.target.positionY + 1) * 200; //this.target.mesh.rotation.y = this.target.meshInitRotY + (this.target.positionY + 1) * 3; } }); Am I missing something very obvious?
