I am trying to apply tweens to several elements into an array that I am looping though. I have created 4 timelines, two entrances and two exits for two sets of items. I am getting this error on the first timeline (assuming it would apply to all four) I can't use a codepen link because I am doing this in SL for a client. But I can at least post the source code. I assume there is something simple but I am just not seeing it. const player = GetPlayer(); const menuOpen = player.GetVar('boolean_menuOpen'); const menu = document.querySelectorAll("[data-acc-text='TOC-Modal']"); const searchFor = 'TOC-Modal-Slide'; const accessibilityItems = document.querySelectorAll("[data-acc-text]"); const slides = []; const menuReady = (bool) => { return bool; }; const slidesReady = (bool) => { return bool; }; const showButton = (bool) => { return bool; }; const menuEntrance = gsap.timeline({paused: true, defaults: { duration: 0.5, scaleX: 0, scaleY:0, opacity: 0, ease:"back.inOut(1.2)" } }); const menuExit = gsap.timeline({paused: true, defaults: { duration: 0.5, scaleX: 1, scaleY:1, opacity: 1, ease:"back.inOut(1.2)" } }); const slidesEntrance = gsap.timeline({delay: 0.1, paused: true, defaults: { duration: 0.25, scaleX: 0, scaleY:0, opacity: 0, ease:"back.inOut(1.2)" } }); const slidesExit = gsap.timeline({delay: 0.1, paused: true, defaults: { duration: 0.25, scaleX: 1, scaleY:1, opacity: 1, ease:"back.inOut(1.2)" } }); menu.forEach((item) => { item.style.opacity = 0; item.style.transformOrigin = 'center'; console.log(typeof item) if(!menuOpen) menuExit.to(item, { onComplete: menuReady, onCompleteParams: true }); else menuEntrance.to(item, { onComplete: menuReady, onCompleteParams: true }); }); accessibilityItems.forEach((item) => { if(item.getAttribute('data-acc-text').includes(searchFor)) slides.push(item); }); slides.sort((a,b) => { const valueA = a.getAttribute('data-acc-text').split('-')[3]; const valueB = b.getAttribute('data-acc-text').split('-')[3]; return valueA - valueB; }); slides.forEach((slide) => { slide.style.opacity = 0; console.log(typeof slide) if(!menuOpen) { slidesExit.to(slide, { opacity: 0, onComplete: slidesReady, onCompleteParams: true }); player.SetVar('boolean_menuAnimationComplete', false); } else { slidesEntrance.to(slide, { opacity: 1, onComplete: slidesReady, onCompleteParams: true }); player.SetVar('boolean_menuAnimationComplete', true); } }); if(menuReady && slidesReady) { if(!menuOpen) { menuExit.play(); slidesExit.play(); } else { menuEntrance.play(); slidesEntrance.play(); } }

I am using gsap scrolltrigger to toggle a class that makes the container sticky. After the end of the animation when the class is removed it behaves weirdly. Here is the video link : https://drive.google.com/file/d/12WOmmK43dFBxvVLKuDPoAGnOAT4-b76L/view?usp=sharing As you can see in the video after the end of animation it moves it..... Is there any fix to this ? Javascript code : const canvas = document.getElementById('hero-lightpass'); const context = canvas.getContext('2d'); const frameCount = 45; const currentFrame = index => `./assets/medium_${(index + 1).toString().padStart(4, '0')}.jpg`; canvas.width = 600; const images = []; const airpods = { frame: 0, }; for (let i = 0; i < frameCount; i++) { const img = new Image(); img.src = currentFrame(i); images.push(img); } console.log(canvas.width); gsap.to(airpods, { frame: frameCount - 1, snap: 'frame', scrollTrigger: { trigger: '.sticky-wrapper', scrub: 0.5, markers: true, start: 'top 48px', end: 'center 49px', toggleClass: 'sticky', }, onUpdate: render, }); images[0].onload = render; const getheight = () => {}; function render() { console.log(images[0].naturalHeight); const h = images[0].naturalHeight; const w = images[0].naturalWidth; const aspect = h / w; console.log(aspect); canvas.height = aspect * canvas.width; context.drawImage(images[airpods.frame], 0, 0, canvas.width, canvas.height); }

Hi there guys, I am very confused. I have a design with lots of lines(roads) which are connected to sections through out the page like on the image on this image given below. Am i able to add those like exactly on the picture with help of gsap and animate the truck on them while scrolling ?

hi guys, i want to achieve https://dexternavy.com like hover effect. i have tried it using this cdn 'https://cdnjs.cloudflare.com/ajax/libs/gsap/1.18.0/TweenLite.min.js' but it not work as i thought and i am stuck here. Any help would be greatly appreciated.

At first sight an easy animation causes lags and is choppy on mobile devices. In Chrome I can reproduce it by going to F12 > emulate mobile > iPhone 6/7/8. And when the page is scrolled down it's possible to see that the animated text is kind of jiggling up and down, in other words, it's choppy. GIF with visual representation

Hi, I am new to greensock and I need little help with it. I am trying to reveal few words (2-3 words in a line) as the ball rolls across the x-axis. Is there a way to do that? In my code, the ball rolls till then end and then displays the text, but I want the text to be displayed as the ball moves across.
