Limit Observer to pointer

[Thomas Günther]

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.

Great catch, @Thomas Günther. Sorry about the confusion there. That's fixed in the next release, but for now it should be as simple as wrapping your .observe() in this:

if (ScrollTrigger.isTouch !== 1) { // <- skip if it's a touch-only device
  ScrollTrigger.observe({
    type: "pointer",
    ...
  });
}

Thanks for the quick answer, @GreenSock! I'm glad you could fix it 👍

 

In the meantime the isTouch is also a much better solution than my event type condition, thanks!
