shikari Posted September 12, 2020 Share Posted September 12, 2020 Hi! First of I want to thank GreenSock team for such usefull library. You're doing amazing job! I've just started using GSAP and not experienced with that. So what I need is to create an animation on a picture which would first scale down on page load and then scale up on scroll down and scale down on scroll up :) That might sound confusing. Hope you get what i mean. On a codePen link I've attached, I'm trying to accomplish what I explained above. There two gsap blocks: the first one is responsible for the animation which is triggered on load; the second one is for animating the picture when I start scrolling up and down. It doesn't work as I expect. But If I comment either of two blocks the other one will work as needed. So I would appreciate If you help me out with my issue and probably show me best practices of how to do that.

akapowl Posted September 12, 2020 Share Posted September 12, 2020 Hey @shikari - welcome to the forum. First off, I removed ScrollMagic from your pen, because it is not a Greensock product, you neither need nor use it in your pen, and it was throwing errors - also, you probably don't need jQuery in there, too. You could maybe set the scene like this ( I used a timeline here, not a single tween, like you did - might not be neccessary ) var tl = gsap.timeline({ paused: true }); tl .to(fullWidthPicture, { scale: 1.3, duration: 1.5, ease: "sine.inOut" } ) ; tl.reverse(1.5); on page load you reverse that timeline from its end, so it scale down from scale 1.3 to scale 1.0. Then with a timeout dependend on the duration of your tween, you could initiate the ScrollTrigger after that tween is done var timeout = gsap.delayedCall(1.5, function() { ScrollTrigger.create({ trigger: fullWidthPicture, toggleActions: "play none reverse none", markers: true, start: "0 50%", end: "100% 0%", scrub: 1, animation: tl, }); }); That results in this: See the Pen 6921915ffa41edc59d6c27d65a618f22 by akapowl (@akapowl) on CodePen When you are in full-window mode, you'll notice, that when the ScrollTrigger is being initiated, the image will start to immediately scale up a bit again - that is, because the image has already passed the set start-point of the ScrollTrigger, thus the tween of it will be executed for the portion, that it is already past that start-point. Hope this is at least an inspiration for how you could set things up. Cheers. Paul 5 Link to comment Share on other sites More sharing options...
