    GSAP ScrollTrigger - Container div moving on entry trigger

    in GSAP

    Posted

    Screen recording of the issue i'm referring to:
    https://www.dropbox.com/s/nh2f5gm67xhanpa/Screen Recording 2023-02-10 at 1.26.47 PM.mov?dl=0

    Background: 
    I have a remix / react application and i'm trying to get scrolltrigger to pin a container element.  I've read through other posts, but can't seem to figure this out.  You can see I set the end to be 900px, this appears to move the entire div down 900px on trigger entry.  You can see when I scroll back up and it's triggered through the "end" marker it works as intended - but for some reason the entry marker makes everything shift.  Any ideas?

    I've tried removing elements and simplifying to see if any parent container or div was the problem and it doesn't seem to be the issue.

      

    useEffect(() => {
    gsap.registerPlugin(ScrollTrigger);
    let tl = gsap.timeline({
      scrollTrigger: {
        trigger: '#everybodyWins',
        start: 'top 20%',
        scrub: 1,
        pin: true,
        end: '+=900',
        markers: true,
      },
    });

     

    On first click animation plays smooth, subsequent clicks causes delay on start

    in GSAP

    Posted

    I have a button that when clicked, triggers my timeline to play.

     

    There is no delay on start and on the first click it works fine.  On subsequent clicks, it takes time for the animation to start.  Any idea what I'm doing wrong?

     

    I've tried triggering the animation with just TL.restart() and also having an onComplete function that sets the timeline's progress to 0 and pauses it.  Any idea how I remove that delay on subsequent clicks?

    Code here:

    var tl = new TimelineMax({paused: true, onComplete: resetTl});  
TweenMax.set('.fab', {perspective: 200})

tl.to('#sendplane', 1, {rotation: -20, opacity: 0, x: '+=100', ease: Elastic.easeIn.config(1, .9), onComplete: resetPlane})
.to('.fab', .25, {scale: 1.2, boxShadow: '0px 7px 15px rgba(0,0,0,0.1)'}, '-=.8')
.to('.fab', 2, {rotationY: -360, ease: Elastic.easeIn.config(1, .9)}, '-=1.8')  
.fromTo('.checkmark', .5, {drawSVG: '0%'}, {drawSVG: '100%'})
.to('.fab', 2, {rotationY: 360, ease: Elastic.easeIn.config(1, .9)}) 
.to('.checkmark', .2, {opacity: 0}, '-=1.1')
.to('#sendplane', 1, {x: '+=100',opacity: 1}, '-=.4')
.to('.fab', .25, {scale: 1,boxShadow: '0px 0px 5px rgba(0,0,0,0.3)'})

function resetPlane(){
  TweenMax.set('#sendplane', {x:'-=200', rotation: 0, opacity: 1})
}
function resetTl(){
  tl.progress(0)
  tl.pause()
}

document.getElementById('fab').addEventListener('click', function(){
  tl.play()
  //I've also tried tl.restart() and it still has a delay.
})

    Accordion Menu / Reverse timeline doesn't seem to always reset all the way

    in GSAP

    Posted

    I've been trying to create an accordion menu with GSAP.  I have 3 menus and I want the others to reverse their animations when one is clicked.  Each menu item also has a hover state.. which I think is causing my issue.

     

    If you click around on the menu items quickly, then sometimes an element is left with it's old boxshadow property.

     

    If you check out the codepen I think you'll get a good idea of what I'm talking about.  Is there a better way to do what I'm trying to do?
