Updating a Timeline & ScrollTrigger

Hello,

 

I'm struggling with making my timeline with ScrollTrigger work on resize. It works perfectly every time if I refresh the page, but it doesn't update properly on resize. 

I have applied both of below:
invalidateOnRefresh: true
x: () => value(instead of x: value)

What am I doing wrong? I am attaching my whole component code (I have just stripped imports). The aim is to simply make it appear as horizontal scroll for the list.

I will appreciate any help. Thank you.
 

export function Companies({ data }: { data: Sanity.Company[] }) {
  const listRef = useRef<HTMLUListElement>(null);
  const itemsRef = useRef<(HTMLLIElement | null)[]>([]);

  const tlRef = useRef<gsap.core.Timeline | null>(null);

  useGSAP(
    () => {
      gsap.registerPlugin(ScrollTrigger);
      const mm = gsap.matchMedia();
      mm.add("(min-width: 1024px)", () => {
        if (!itemsRef.current[0]) {
          return;
        }

        tlRef.current = gsap.timeline({
          scrollTrigger: {
            trigger: listRef.current,
            start: "bottom bottom",
            end: `+=3000`,
            scrub: 2,
            pin: true,
            invalidateOnRefresh: true,
          },
        });

        tlRef.current.to("li:nth-child(-n + 5)", {
          y: "0%",
          stagger: 0.1,
          duration: 1,
        });

        tlRef.current.to(listRef.current, {
          invalidateOnRefresh: true,
          x: () =>
            `-${itemsRef.current[0]?.offsetWidth * itemsRef.current.length - window.innerWidth}`,
          duration: 4,
        });
      });
    },
    { scope: listRef }
  );

  return (
    <ul
      className="grid grid-cols-2 gap-x-8 gap-y-24 px-15 pb-52 sm:grid-cols-3 lg:flex lg:w-fit lg:flex-nowrap lg:justify-between lg:gap-0 lg:px-32"
      ref={listRef}
    >
      {data?.map((company, index) => (
        <li
          className={cx(["lg:pr-[7vw]", index < 5 ? "lg:translate-y-full" : ""])}
          key={index}
          ref={(el) => {
            itemsRef.current[index] = el;
          }}
        >
          <Company {...company} />
        </li>
      ))}
    </ul>
  );
}

Without a minimal demo, it's very difficult to troubleshoot; the issue could be caused by CSS, markup, a third party library, a 3rd party script, etc. Would you please provide a very simple CodePen or Stackblitz that illustrates the issue? 

 

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best. See if you can recreate the issue with as few dependencies as possible. Start minimal and then incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen

that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo

 

Using a framework/library like React, Vue, Next, etc.? 

CodePen isn't always ideal for these tools, so here are some Stackblitz starter templates that you can fork and import the gsap-trial NPM package for using any of the bonus plugins: 

 

Please share the StackBlitz link directly to the file in question (where you've put the GSAP code) so we don't need to hunt through all the files. 

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions.
