Multiple pins causing second pin to break

[Akash Ranjan]

Hello,

I am stuck into a weird problem. I am working in next JS and I have two components that have the identical animations. The problem is that the pin of first element is causing the pin of second element to break as you can see on codepen. Can you please tell me what I am doing wrong here.

 

This is the code I am using inside both the components. Selectors are different for both of them.

 

Please help me

  useEffect(() => {
    if (window.innerWidth > 767) {
      let ctx = gsap.context(() => {
        let serviceSection = document.querySelector('.service-block');
        gsap.to('.service-block', {
          x: () => serviceSection.scrollWidth * -1,
          xPercent: 100,
          scrollTrigger: {
            trigger: '.service-block',
            start: '0% 20%',
            end: '+=2000px 10%',
            pin: serviceWrapper.current,
            scrub: 0.5,
            invalidateOnRefresh: true,
            // markers: true,
          },
        });
      }, serviceWrapper.current);

      return () => ctx.revert();
    }
  }, []);

 

 

Thank You

Hi,

 

In React always use the useGSAP hook, is far simpler and cleaner:

https://gsap.com/resources/React

 

Here is a simple demo that uses the useGSAP hook with GSAP MatchMedia:

https://stackblitz.com/edit/vitejs-vite-pfhzkf?file=src%2FApp.jsx

 

Also in your codepen you're using the same element as the trigger:

gsap.to(".work-block", {
  x: () => horizontalSection.scrollWidth * -1,
  xPercent: 100,
  scrollTrigger: {
    trigger: ".work-block", // FIRST TRIGGER
    start: "center center",
    start: "0% 50%",
    end: "+=2000px 30%",
    pin: ".work-wrapper-main",
    scrub: true,
    invalidateOnRefresh: true,
    markers: true
  }
});

gsap.to(".work-block-2", {
  x: () => horizontalSection2.scrollWidth * -1,
  xPercent: 100,
  scrollTrigger: {
    trigger: ".work-block", // FIRST TRIGGER AGAIN HERE!!!
    start: "center center",
    start: "0% 50%",
    end: "+=2000px 30%",
    pin: ".work-wrapper-main-2",
    scrub: true,
    invalidateOnRefresh: true,
    markers: true
  }
});

Changing that to trigger: ".work-block-2" seems to work the way you expect.

 

Hopefully this helps.

Happy Tweening!

Hey @Rodrigo,

 

Thanks for your reply. I tried useGSAP hook but still I am having the same problem. It is working on my codepen but not in my project. It is a strange issue as if I dont put the elements in separate components and keep the code as it is on the page with both the useGSAP hooks it works. But if I make components for both of them the second one breaks.

The problem is the second pin scrolltrigger start point is off from the amount of pinspacing from the first element. I tried removing pin from first element and second element started working fine. I dont know what is causing this issue. Please help

 

  useGSAP(
    () => {
      const mm = gsap.matchMedia();
      mm.add(
        {
          small: '(max-width: 767px)',
          large: '(min-width: 768px)',
        },
        (ctx) => {
          const { small } = ctx.conditions;
          let serviceSection = document.querySelector('.service-block');
          gsap.to('.service-block', {
            x: () => serviceSection.scrollWidth * -1,
            xPercent: 100,
            scrollTrigger: {
              trigger: '.service-block',
              start: '0% 20%',
              end: '+=2000px 10%',
              pin: serviceWrapper.current,
              scrub: 0.5,
              // invalidateOnRefresh: true,
              // markers: true,
            },

Hi,

 

Unfortunately there is not a lot we can do without a minimal demo. If you have your ScrollTrigger instances in different components, be sure to use the right selectors and scoping.

 

Try to create a minimal demo on Stackblitz that clearly replicates the issue, please don't use the full project or a git repo since that makes it more difficult to fork and find the issues since we have to go through a lot of files and lines of code, the simpler the better.

 

Happy Tweening!
