  1. I'm wondering if it's possible to use the MorphSVGPlugin only for the shape, not for the position of elements.


    My use case: I want to morph an object randomly into one of many objects. I know I can duplicate the objects onto every drop, but I feel like there's a better solution.


    Thank you!

  2. Heya 👋


    I noticed I can not limit an Observer to type: pointer. It will always trigger, also on mobile/touch devices.


    While I can use a condition like e.event.type.includes('pointer') I'm wondering if this is a bug.


    In this codepen I listen to onLeft and onRight but I don't want this on mobile devices. It will scroll, jump back and then animate the scroll.

  3. I'm currently trying to scroll a horizontally overflowing element via vertical scroll. A lot of people don't have a trackpad, horizontal mouse wheel or the knowledge you can hold shift to scroll horizontally. Those that do should however still be able to scroll horizontally.


    Now I know you can use something like ScrollTrigger to turn the scrolling into transforms but I'd like to keep the regular scroll behavior, including a scroll bar, the native mobile behavior, etc.


      target: window,
      type: "wheel",
      onChangeY: (self) => {
        document.documentElement.scrollLeft += self.deltaY;


    With a simple Observer I turn the vertical scroll into horizontal scroll but I noticed some issues: the speed seems to be doubled and the scroll doesn't look very smooth.


    Maybe somebody has an idea why that is? Thanks in advance!


    I created a simplified CodePen that you might want to open in a new tab to test the scrolling:

  4. Hey @OSUblake

    Thanks a lot for your solution. This indeed works much better for the CodePen.

    Unfortunately I made the demo a bit too minimal as it seems. On the actual website I have color changer "lines". That's why start and end were both set to top center and I used a reversed timeline. Sorry, should have included that in the initial post/demo.

    I forked the demo and created a new one closer to the actual structure:

    Thanks again,

  5. I'm currently building a page with sections that change the body background color when they are scrolled into view. Doing this with ScrollTrigger was very easy but I stumbled upon an issue when scrolling up without scrolling down first. This might sound weird but it can happen when you open the page with an anchor tag or reload the page anywhere but on the very top. The color animation is all messed up then. Since this is hard to explain I created a simplified CodePen with a #bottom anchor and a video of the issue. To test it yourself you need to open the CodePen in debug mode.


    I guess it has something to do with the reversed to tweens that don't have a correct initial state. Any idea how to solve this? Thanks in advance!

  6. I'm trying to set up a button that moves to a fixed positioning (top right) when scrolling. Easy enough with FLIP and ScrollTrigger, I just have an issue with how the animation looks when moving from relative to fixed positioning. It looks like it immediately moves to the top (fixed positioning?) and animates to the top right from there. It looks fine the other way around.

    I already tried adding the position property to props, both in getState() and Flip.from() — didn't help. I also noticed the same issue on this official pen when the viewport can be scrolled and the button is not at the very top:

    A few weeks (or months?) ago there was a thread about this with a similar call to action button but I can't find it via the search or Google.

    Thanks for any help!
