How to fade out when the image is scrolled in slider using gsap?

[Zain12]

Hi respected community. I am making a slider where on vertical scrolling the images in the sliders are scrolled horizontally. My slider is working fine but i want to add a functionality that when a user scroll the image, it fades out and the next image appears and so on. Here is my code. I have excluded the component name and other stuff to keep the code precise. thanks

 

  useLayoutEffect(() => {

    const ctx = gsap.context((self) => {

 

      const sections = self.selector(".about");

      const horizontalTween = gsap.to(sections, {

        xPercent: -99 * (sections.length - 1),

 

        ease:"fade",

        scrollTrigger: {

          trigger: wrapperRef.current,

          pin: true,

          markers: false,

          scrub: 1,

          end: "+=3000",

         

        },

     

      });

 

   

 

     

      // console.log(document.querySelector(".wrapper").offsetWidth)

    }, wrapperRef);

    return () => ctx.revert();

  }, []);
 

 return (

 

       <div className="sliderSection"  ref={wrapperRef}>

        {images.map((img) =>(

          <div key={img} className="about" >

            <Image  className="aboutImg" src={img} />

          </div>

        ))}

 

          <video

            autoPlay

            loop

            muted

            playsInline

            className="sliderBgVideo">

            <source src='/images/vids/backgroundVideoTwo.mp4' type="video/mp4" />

          </video>

 

      </div>

 

  )

It's pretty tough to troubleshoot without a minimal demo - the issue could be caused by CSS, markup, a third party library, your browser, an external script that's totally unrelated to GSAP, etc. Would you please provide a very simple CodePen or CodeSandbox that demonstrates the issue? 

 

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

 

Here's a starter CodePen that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo:

If you're using something like React/Next/Vue/Nuxt or some other framework, you may find StackBlitz easier to use. We have a series of collections with different templates for you to get started on these different frameworks: React/Next/Vue/Nuxt.

 

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

I have attached the minimal demo. I want the image to be fade out as it is scrolled

Hi,

 

I didn't had the time to fork your demo so I created another one using GSAP Container animation:

Hopefully this helps. Let us know if you have more questions.

Happy Tweening!
