I'll try to explain a little bit more in-depth, I'm making a set of animations for a website and the client essentially wants a preview of how each element reacts to each other as you're scrolling down the page. I have no experience with website development and that is fine for this job, as all im doing is setting up an interactive preview for the developer.
So far I've parented all the elements to a Null object and the Y position value of that null to slider controls and so far so good.
Now where I'm lost or in fact, confused if it's even possible within AE is to set up each animation element to start its sequence once I scroll the slider to a specific value? I'm not too familiar with expressions so any help will be appreciated.
If you need me to explain in more detail please do ask, hopefully I've tried to make it clear for what I'm asking 👍🏽
