  1. Hi @aaron4osu


    Welcome to the forum.


    If this project is a bit overwhelming, I'd suggest going to the Learning Center and starting a bit smaller.

    That being said, you'd want to use a timeline and stagger to achieve the emptying of each bowl. Here's a quick fork showing what I mean.

    Obviously the images are not hitting the target correctly (as you noted). That will mainly be a CSS issue. If you want to use divs like that, you'll need to make some calculations about how far away the middle bowl is and listen for resize events. Another option would be to place all of the elements in an SVG and then everything scales together so you can use hard coded values.


    If you want the final product to look exactly like the filled bowl, you may want to work backwards and use .from() tweens. Lots of options are possible, but as I mentioned, you may want to start with something a little easier after you've gone through the Learning Center.


    Happy tweening.

  2. Thanks for the demo. My advice from above would stand. I'd probably just use a .fromTo() tween in that ScrollTrigger timeline. 


    I'd also recommend scaling the text element rather than the whole container. You can see horizontal scrollbars appear when you scale the whole thing. Just my two cents. YMMV


    Happy tweening.

  3. Hi @willdzoan31


    Welcome to the forum. :) 


    You are correct. That jump is because of the first tween.


    Some solutions:

    • Create your ScrollTrigger in a function that is called when the first tween completes.
    • Wrap your target in another element and scale that one in the ST tween.
    • Use a fromTo for the ScrollTrigger tween (1 → 4)


    That's my best advice without actually seeing the code in context with a minimal demo.


    Happy tweening

  5. There are a few problems here.

    • Your trigger element (.hp-360) doesn't exist
    • There are several elements with CSS transitions
    • Your start and end are both set to "35% 70%", but you have scrub set to true


    If you decide which element should be the trigger and remove the CSS transitions on everything GSAP will be animating, I think you'll be good to go.

  6. Hi @Tanvi_Patel


    Welcome to the forum.


    The moving background is a series of seamless repeating SVGs. Here's a thread with seamless clouds using the same technique.


    The animated stag is a sprite sheet.

     That should get you pointed in the right direction.


    Also be sure to visit the Learning Center to help you get started.

    Happy tweening.

  7. Correct - the duration of a tween doesn't make much difference with scrub. It's all about ratios. Two 1 second tweens on a scrub timeline will be the same as two 10 second tweens on a timeline. (Each taking up 50% of the scroll distance) However, changing just one of them to 10 seconds will make a big difference.  Now, the 1 second tween is only taking up approximately 9% of the scroll distance while the 10 second one is take up approximately 91% because we have a total of 11 seconds.


    My personal preference is to use linear eases on scrub tweens/timelines, but yes you can certainly use a custom ease on a scrub tween if that's your preference. I'd say just give it a try and see what what works.


    Happy tweening.

  8. I don't think there's anything wrong with the way you did it and a few extra ScrollTriggers aren't going to make a noticeable difference. Jack is a performance connoisseur so I trust GSAP and don't get too wrapped up in all things performance until I notice something chugging along. That's almost always going to be a rendering issue though. 


    The yoyo tween I posted above will have a brief period of time with nothing changing. That's why there is a repeat delay. Say you have the above code with a 1 second tween duration and a 2 second repeat delay. That's a total of 4 seconds. So, the first 25% of the scrub will be the tween to full opacity. 25% → 75% of the scrub is nothing as that is the delay. Then 75% → 100% would be the fade back to the original opacity.


    Make sense?


    Happy tweening.

  9. If you want the opacity to fade in on each repeat, you'd need to add it to the smoke timeline. Right now you have it in the setTimeout function. Why not just make it part of the main smoke timeline?

  10. I'm pretty sure killTweensOf will indeed kill the associated ScrollTrigger. Though, any ScrollTriggers associated with timelines will remain. It's easy enough to kill all the ScrollTriggers if needed.


      ScrollTrigger.getAll().forEach((t) => {

    Happy tweening.

  11. You can do it like that or you could use a yoyo tween. Something like this should work:


    const anim = gsap.to(containerRef.current, {
      opacity: 1,
      ease: "none",
      yoyo: true,
      repeat: 1,
      repeatDelay: 2,  
      scrollTrigger: {
        trigger: containerRef.current,
        start: "top center",
        end: "bottom center",
        scrub: true

    Happy tweening.

    Basically my question is how do I start the opacity animation when the x-axis movement going to complete


    I think you're looking for the position parameter. This will allow you to start the opacity fade before the x movement completes.

  13. If I'm animating it with GSAP, I always use GSAP to set everything so we don't encounter any CSS problems. In this case, I think it'll be easier to use SVG origin for the head group rotation point.
