Hi team! I've been struggling for a while to get some conditional logic in place with my animations. Some quick backstory to give my codepen some context...Anyone who's curious can also see my two other threads, all related to the same project, but I thought I would make a new one with a greatly reduced example. There are LOTS of other questions about animating list items, but not many with react? And none that I've seen that involve potentially large amounts of data, or conditional logic mixed into the timeline? Backstory: I've built an interactive USA map using D3/react-simple-maps, it shows all of my companies bookings on a 5 minute delay...usually close to 50 at a time...100-150 an hour, about 8,000 in a day! That's a lot dots to show on a map! Thanks GSAP for your awesome timeline and stagger methods to make it more digestible. So...enter the 'ticker'... I decided in addition to the map I would add a sidebar that has a card with data on each booking, like who it is, the dollar amount etc. These cards appear in the ticker at the same time dots appear on the map. Now that we're live, everyone wants new features. "Wouldn't it be cool if there was a booking over a certain dollar amount, we could show a whale fly across the screen?" How do I that???? A couple of things, then some code! - Because these ticker cards contain lots of data, I do want them to pause in place for long enough that someone could read them if they wanted...after digging through forums and lots of codepen examples, the best I could come up with was multiple staggerFromTos chained together! It's pretty choppy but it works...ish. The one that is live has better timing than the the codepen! Also - no map in this example - just list items...and a cheeseburger callback! - I've been playing around with .add and .call, or adding a label somewhere to my timeline - not quite there yet! - Nothing I've done actually considers the data! In my codepen, I've created an array with id, and values, and I'm hoping if a card reaches the top of the box (or anywhere in the box) and has a value greater than 10, it will call the cheesburger animation to do its thing? Any ideas? what am I doing wrong? Where should this conditional logic live - within the function, or outside of the timeline somewhere...possible in componentDidMount or DidUpdate? - I'm still getting the hang of react and its ways...but our best practice is to use keys when going through an array with the .map() method, and use createRefs to set targets for the animation. Is there a way I can access a particular card by it's key or ref etc? https://stackblitz.com/edit/react-iiesig?embed=1&file=index.js Thanks!
