Hey guys, I'm playing a bit with GSAP to use for my future website. Gonna drop Snapsvg and only use jQuery along with GSAP. I was wondering how I could ease an animation in reverse differently? So let's say anim.play() will use ease:Elastic.easeInOut and the reverse() would use eg. ease:power1.easeOut. Is this possible? Here is a code-axample which I'm currently playing with; var animateThumbs = function() { var $anchors = $( 'div.col-md-4' ).children( 'a' ), ellipse = $($anchors[0]).find( 'ellipse'), duration = .25, ellipseProps = { from: { cy: ellipse.attr('cy'), rx: ellipse.attr('rx'), ry: ellipse.attr('ry') }, to: { cy: -500, rx: 625, ry: 725 } }; //Let's set on every a-element a timeline as method $anchors.each( function(index, elem) { var ellipse = $(elem).find( 'ellipse' ), animateSvgBG= new TimelineMax({repeat: 0, paused: true }); animateSvgBG.fromTo(ellipse, duration, //from { attr: { cy: ellipseProps.from.cy, rx: ellipseProps.from.rx, ry: ellipseProps.from.ry }}, //to { attr: { cy: ellipseProps.to.cy, rx: ellipseProps.to.rx, ry: ellipseProps.to.ry }} ); //animateSvgBG.to(ellipse, 1, { attr: { cy: ellipseProps.from.cy, rx: ellipseProps.from.rx, ry: ellipseProps.from.ry }}, "fadeOut"); //labelsArray = animateSvgBG.getLabelsArray(); //console.info(labelsArray); elem.animate = animateSvgBG; }) $anchors.on({ mouseenter: function(event) { // from "fadeIn" to "fadeOut" //TweenMax.fromTo(animateSvgBG, duration, {time:labelsArray[0].time}, {time:labelsArray[1].time}); //console.info( "animateSvgBg: " + animateSvgBG, " labelsArray[0].time: " + labelsArray[0].time, " labelsArray[1].time: " + labelsArray[1].time ); this.animate.play(); }, mouseleave: function(event) { // nfrom "fadeOut" to "fadeIn" //TweenMax.fromTo(animateSvgBG, duration, {time:labelsArray[1].time, ease:Ease.easeOut}, {time:labelsArray[0].time}); this.animate.reverse(); } }) }

Is there any way that customease can be converted to the cubic-bezier() for css? tks.

Hello, I encounter an issue with easings. Basically the problem is that animation speed up at the end of a tween, even when I stipulate ease:none in a tween. I can't reproduce on a codepen, I am working on a nextJs project. Here is the component that is animated export default function Template({ children }: { children: React.ReactNode }) { const transition = useRef(null); useGSAP(() => { transitionEnter(); }, []); return ( <div className='relative h-screen w-full overflow-hidden'> <div ref={transition} id='transition-wrapper' className='absolute left-0 top-0 h-full w-full bg-black transition' ></div> {children} </div> ); } And here is my animations export const transitionEnter = () => { const el = document.querySelector('#transition-wrapper'); const tl = gsap.timeline({ onStart: () => { console.log('transition start'); }, onComplete: () => { console.log('transition end'); }, }); tl.to(el, { y: window.innerHeight, ease: 'none', duration: 1, }); }; export const transitionLeave = (router: AppRouterInstance, route: string) => { const el = document.querySelector('#transition-wrapper'); const tl = gsap.timeline({ onStart: () => { console.log('enter start'); }, onComplete: () => { console.log('enter end'); router.push(route); }, }); tl.to(el, { y: 0, duration: 1, ease: 'none', }); }; And the result here, we can clearly see that the animation speed is not linear. And it is even worst when I use other easing function. gsap.webm I think there may be something to do with useGsap/Next but I run out of idea. If someone have some ideas. Thanks.

I have a gsap timeline, which I trigger on hover and play it reversed on mouseleave. However I need to change the easing when I play the timeline reversed. Is there a way I can do this without duplicating the whole timeline again? Here is a stripped down example, full example is in the codepen. const ease = 'power2.out' const tl = gsap.timeline({ paused: true }) // tweens here... card.addEventListener('mouseenter', (e) => { tl.play() }) card.addEventListener('mouseleave', (e) => { // need to somehow change the easing to 'power2.in' here tl.reverse() })

Hi! everyone. this is my demo tunnel https://codesandbox.io/s/digit-tunnel-4vkc91?file=/src/index.js and i wanted to add easing with GSAP to make mousemove more smooth, like in this website https://archiviostoricoexperience.gruppotim.it/en/optical-fibre .. but couldn't achieve such smooth easing effect , can someone help .?

Hey Greensock Would be great to have the progress() function return 0-1 normalized with the selected easing. I just animated the rotation of car wheels, and needed that rotation to match the easing of the tween of the car's movement. Ended up using my own method, by fetching one of the tweened properties ( (current_value-start_value)/(end_value-start_value) ), but a generic progressWithEasing(), or another property to the progress() method, like 'normalize with easing' or something would be great... Cheers.

Is there simple way to create a linear.none ease but with a slight deceleration in the last 10%? Something like this: Without CustomEase plugin ideally

Is there a way to directly use the penner easing functions (and other) included in GSAP? I run my own update loop (on Scroll) and just want to pass my values through the easing functions to make everything a tiny bit more awesome. Example of what I would like to do. passing in p (value of 0 to 1) start value 0, change value 1, and duration 1. Power2.easeInOut(p,0,1,1); right now I define the functions again in my code like this: var easeInSine = function (t, b, c, d) { return -c * Math.cos(t/d * (Math.PI/2)) + c + b; } easeInSine(p,0,1,1); would be great to hook into the greatness of Greensock instead of defining them again. I'm using the latest js and tweenmax.

hi everybody, how proceed to mix diferente ease at start and end : i cant find doc? It possible ? Example: Something like thats, assuming the tween compute the half/time in the process ? TweenMax.to(bar, 1, { rotation:-Math.PI/2, ease:[Back.easeIn.config(1.2), Bounce.easeOut], }); or like this ? TweenMax.to(bar, 1, { rotation:-Math.PI/2, ease:{ start:Back.easeIn.config(1.2) , end:Bounce.easeOut }, }); or ... TweenMax.to(bar, 1, { rotation:-Math.PI/2, ease:{ '0':Back.easeIn.config(1.2) , '0.5':Bounce.easeOut }, }); or... TweenMax.to(bar, 1, { rotation:-Math.PI/2, easeIn:Back.config(1.2), easeOut:Bounce, });

Hi, I'm trying to animate the drag for the swiper with tweenmax. Now the dragging option is to quick and jerky. Dees anyone know how to animate the drag option with tweenmax to have an easing accelerate effect? Here is an example with a slider who has the drag options with nice easing options: http://www.benmingo.com/ Thank you!

hi it possible to use chaining function ease instead of property ? What a read it that TweenLite.to(obj, 2, {pixi:{pivotX:x, pivotY:y},ease:Power2.easeOut}); but i look for a way to write the easing like this, with chaining ? I took this habit on an old Easing library. TweenLite.to(obj, 2, { pixi:{pivotX:x, pivotY:y} } ).ease(Power2.easeOut); Existe a way to write ease more eyes friendly ? thank Am new from some minute ago , so am studying this library:)

In a project I'm doing, I need to match easing feel of elements animated using CSS cubic-Bezier timing function (example:cubic-bezier(0.1, 0.9, 0.2, 1) using tweenmax. Is this supported in GSAP ? I'm trying to avoid writing my own cubic-Bezier plugin if possible Thanks! Orry

Hi. We have a digital signage content editor with many widgets, and 2 of the widgets use gsap with jquery plugin, and we added another jquery plugin for a new widget (http://wowslider.com/), and a few of the features in that library didn't work, I was debugging for a long time when I found that it conflicts with the gsap jQuery plugin, more precisely the easings defined on the jQuery object, for example jQuery.easing.easeInOutExpo, because the easings share the same name in both libraries, but they work differently, the variable has different function references in the two libraries. Currently the gsap definition is in place, which causes some wowslider features to not work. I tested removing gsap, and then those features worked. I already contacted their support, but they couldn't give a solution, and I want to avoid modifying the code of these libraries. All I would like to ask for is some tips to avoid this issue. Is there a no-conflict option in gsap plugin? Can I separate two jQuery instances for the two libraries? Thanks in advance! Roland

Hi, To be honest, I just wanted to try different easings and a countdown. But with a little story it was really funny ... Kind regards Mikel By the way: GSDevTools is very helpful. I noticed, however, that in reverse, the centering of the object (pathDataToBezier) is not interpreted expected. Is that due to my coding?

SteppedEase is convenient for animating in a linear fashion between frames in a spritesheet, but what if I want an easing between each step? Is this possible? Let's say I want a monster to die and go through 10 frames of animation, but I don't want it to go through the frames in linear jumps. What if I'd like a Quad.easeOut through the steps for a more dramatic effect? Is that possible?

Can someone assist me on change this current animation: TweenLite.fromTo(spot_holder[kNumIterator], 2, {left:pointAX, top:pointAY}, {left:pointBX, top:pointBY, immediateRender:false}); to this: TweenLite.fromTo(spot_holder[kNumIterator], { ease: Bounce.easeOut, y: -500 }); or what do I change to make the animation HAVE a bounce effect, zoom effect or any other effect

Hi there! Is it possible to apply only specific interval of ease function to my tween. Something like: TweenMax.to( startPos, 2, endPos ); endPos.ease = Power2.easeInOut.interval(0.25, 0.9); I don't want skip first 0.25 and last 0.1 progress of my tween.

Hi guys, Just a quick query... Using the easing tool at: http://greensock.com/ease-visualizer If you switch to SteppedEase, with it on the graph (as it's clearer), is there any way to force it to take its first 'step' immediately? With config(2) set, it goes along the following axis: x,y,x,y,x Is there a simple way to switch it so that it goes: y,x,y,x I realise that's a slightly shorter transition, and I have worked out that I can use delays in the timeline to achieve the result I'm looking for, I'm just wondering if such an inherent ability exists within GSAP as standard? Thanks a bunch!

Sometimes I thought it would be nice to blend easings from one type to another while time goes by. And then it would be cool to have as much control over how the blending is done as possible. So I created a showcase, not yet a real easing plugin. I don't know how useful it might be to GSAP users, but there are some applications like: Going from linear to an elastic ending or from rough ease to clean ease. This might be especially interesting for long tweens maybe. The syntax is: mixTween(eases,ratios,blendTweens) // example: mixTween( [Linear.easeNone,Elastic.easeOut], [0.2,0.4], [Power2.easeInOut] ); The first array, eases, can be an array of at least 2, but as many eases you like. The second array, ratios will define the time-points of the eases. In the above example, the tween will stay linear until 20% of the tween. Then it starts blending to Elastic.EaseOut until 40% of the tween and stays EaseOut until the end. This parameter can be ommitted. If ommitted, evenly spaced values are calculated. The third array defines HOW the blending should be made. Just linear blending (default if ommited) won't always look best. So you can use any easing function to define how fast one ease blends into the other. In the example above, the easing is smoothly transitioned by a Power2.easeInOut, so there won't be any "sharp" change when the blending begins. You might get a good example of what this does by looking at the codepen I left here I could imagine this to be implemented in a similar way to CustomEase. like BlendedEase(...)

I'm playing around with the new eases, Custom Bounce and Custom Wiggle. Im comparing two identical tweens, except for the easing tl.to(blue, 1, {top:400, ease:"myWiggle"},"start"); with this the item would move down 600px from the top and "stay there"- just a normal tween tl.to(green, 1, {top:400, ease:Power2.easeIn},"start"); this wiggle tween works fine- but the item ends up back in its original position, I am confused by this behavior. I added a third tween using from and that ends up on top as it should, tl.from(red, 1, {top:400, ease:Power2.easeIn},"start"); why does this easing function change the ending position property? I'm not used to that, and not sure how to plan for it. Thanks, Chris

Hi, is there a way to change the easing method of a tween in a timeline when reversing the timeline? My example.: var tlDrops = new TimelineMax({paused:true, delay:2, reversed:true}); tlDrops.from("#geschenkedrops", 0.2, {bottom:0, right:15, ease:Back.easeOut}, "starting") .to("#geschenk", 0.5, {autoAlpha:0}, "-0.1") .to("#merci-button", 0.5, {autoAlpha:1}, "-0.1") .from("#hauptgeschenk", 0.5, {bottom:25, right:25, width:1, height: 1, rotation:180, ease:Elastic.easeOut}, "geschenke") .from("#geschenk2", 0.5, {bottom:25, right:25, width:1, height: 1, rotation:160, ease:Elastic.easeOut}, "geschenke") .from("#geschenk3", 0.5, {bottom:25, right:25, width:1, height: 1, rotation:140, ease:Elastic.easeOut}, "geschenke") .from("#close-button", 0.2, {bottom:25, right:25, ease:Sine.easeOut}) .to("#geschenkedrops", 0, {autoAlpha:1}, "closing"); Now I would like to change all Elastic.easeOut easing methods into a different method (e.g. sine.easeIn) on timeline reverse. Is that possible, or do I need to create an extra timeline for the reverse function? Thanks so much, Rob

I created a new ease that I find myself using a heck of a lot. You could think of it kind of like a backwards Back ease but with some additional smoothing towards the opposite end of the ease. I call it Anticipate. Its great for cartoonish-like motion where there is a build-up followed by a follow through. Picture a baseball player winding up for a pitch and then letting the ball go and it slowly comes to a stop in space. The ball would momentarily go backwards and then fly fast for a while until it came slowly to a stop. This type of animation is a lot more organic than your typical Back.easeOut. If you'd like to try it out... I modified a version of TweenMax to include this ease: TweenMax With Anticipate Ease Or just fork the CodePen demo.

Hey everyone! I have come across a small issue and was wondering if someone could help me sort it out. To quickly give some background: I'm building a simple app which randomly picks a person by spinning a wheel of names. The wheel spins a few times before eventually resting on the target. I've found that with longer animations and more complex easing equations the end of the animation jumps a proportion of the distance / rotation. I've recorded a couple of examples below: Easing: Power0.easeNone Easing: Expo.easeOut As you can see, at the end of the animation there is a tiny little jump. For the sake of the gif I've actually shortened the tween duration and reduced the amount of rotation. If I increase it the jump is even more pronounced. Take a look at the CodePen example as well which illustrates the issue. While setting up that example I also noticed that there is a jump at the beginning of the tween. Does anyone have any ideas of how to sort this? Thanks, Will

Hello, I went throught the doc and couldn't find anything. Is it possible to set an easing function to a timeline and have it like inherited from all the Tweens in the timeline?

Hello, sorry if the title is not really clear. I'm trying to create a horizontal parallax animation with at least three layers. The end result should also be responsive, so I can't really use fixed numbers. Also, the image for the background is not the same size as the others. Let's say that the background is 8000px and the image on top is only 5000px. I want the scrolling to stop when the right border of the second image reaches the outer margin of the browser window. I kind of did it, but not quite right. In the pen I created, as you can see, after the character layer reaches its end, the background still goes on for a little while. Is there a way to avoid this? Or a better approach to the whole thing?
