hpbruna Posted September 14, 2022 Share Posted September 14, 2022 I have hooked up ScrollTrigger with Lottie and this works smoothly. But sometimes the animation is on top of the page and therefor already triggered. At this moment the animation finished animating. But I would like it to animate first and scrub when scrolling down. This is my code: function LottieScrollTrigger(vars) { let playhead = {frame: 0}, target = gsap.utils.toArray(vars.target)[0], st = {trigger: target, pin: false, start: "top bottom", end: "bottom top 50%", scrub: 1}, animation = lottie.loadAnimation({ container: target, renderer: vars.renderer || "svg", loop: false, autoplay: true, path: vars.path }); for (let p in vars) { st[p] = vars[p]; } animation.addEventListener("DOMLoaded", function() { gsap.to(playhead, { frame: animation.totalFrames - 1, ease: "none", onUpdate: () => animation.goToAndStop(playhead.frame, true), scrollTrigger: st }); ScrollTrigger.sort(); ScrollTrigger.refresh(); }); return animation; } LottieScrollTrigger({ target: '#news-title', path: '/static/js/lottie-mte/news.json', scrub: true, start: "top bottom", // when the top of the trigger hits the bottom of the viewport end: "bottom top 50%", }) Any ideas?

GSAP Helper Posted September 14, 2022 Share Posted September 14, 2022 It's pretty tough to troubleshoot without a minimal demo - the issue could be caused by CSS, markup, a third party library, your browser, an external script that's totally unrelated to GSAP, etc. Would you please provide a very simple CodePen or CodeSandbox that demonstrates the issue? Please don't include your whole project. Just some colored <div> elements and the GSAP code is best (avoid frameworks if possible). See if you can recreate the issue with as few dependancies as possible. If not, incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, then at least we have a reduced test case which greatly increases your chances of getting a relevant answer. Here's a starter CodePen that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo: See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen If you're using something like React/Next/Nuxt/Gatsby or some other framework, you may find CodeSandbox easier to use. Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions. Link to comment Share on other sites More sharing options...
