In my codepen I am using ScrollMAgic to trigger a scrollto. The issue is when you scroll back up, it triggers again and forces you back down. How do I disable the trigger, but only in the up direction?


What I mean by this is, I want to disable the trigger when a user scrolls up, but have it fire again when a user scrolls down.

Hi Ritch, have you tried to add reverse: false to the Scene options?

  triggerElement: '.trigger',
  triggerHook: 'onLeave',
  reverse: false

This should only trigger your animation once.


Hope that helps.

Hey thanks for your response Petr and also thanks for creating all of your video tutorials! 


I havn't tried that, as I want the animation to run multipule times and to reverse, but if it's possible - to only trigger the scrollto animation when a user moves from top to bottom. So if a user moves back up the page, the scrollto is ignored. Is this even possible?
