Infinite carousel that moves faster on scroll

Hi guys, 

 

I has been some times I am trying to figure out how I should proceed with an infinite carousel  with images of different widths.

 

Here is my code pen 

 

On codepen the images are not moving but it is working fine on my computer. I am guessing that the code I juste added is not optimised enough (specially the first animation)... 

 

The weird part that I dont get is that my offset initiated through scrolling doesnt work however when i console.log() into the modifiers of my first function I can see it recorded but the images dont move more rapidly.

 

Any idea how I could optimise this code and why offset doesnt work?

 

Thank you!

The images are now moving fine and the infinite loops works.


What still does not work is the offset not being taken into account even though when I console.log it i can see when I enter the scrolling area that my offset value changes but the images are not moving faster. 

 

Any idea what is happening? 

 

Thank you

 

 

 

 

@ZachSaucier I dont think so. 

 

 imgArrConst.map((img,i) => {
            let imgWidth = img.getBoundingClientRect().width
            //initial left position depending on previous photos
            let leftPosition = imagesPosition
            //positioning the images before moving them
            gsap.set(img, {left: (leftPosition)  } )
            imagesPosition += imgWidth
            //calculating total imgs width
            totalW += imgWidth
            //create hash of width per index
            imgWidths[i] = totalW
 })

This fonction above allows me to calculate the totalW of all images combined.

I console.log(totalW) and it seemed to give me the appropriate value.

If you console.log() the actual value that you're passing in you can see that your calculation isn't taking the offset into account. Perhaps you want this instead?

mod(parseFloat(x) + offset)

I think it'd help you if you used better code formatting because you'd be able to more easily catch errors like that.
