Welcome to the final blog post on delaying Edge Animate animations. I'm saying final just because I can't believe how such a simple thing has turned into so many different blog posts, so many different variations, and so many different fun diversions. Most likely because I said this will be the final post, someone will discover some other interesting opportunity and I'll have to write a part 5. But hey - that's the fun part about being a developer, right? Before we start though, please be sure you've read the earlier posts. I'll link to them at the bottom.

I had an interesting discussion with Felix in the comments on my second blog entry on this topic. He discovered an interesting bug. If the animation was scrolled into view, it would play. If the animation completed, and you scrolled it a bit, but just a tiny bit so it never left the view, it would start over.

The issue was simple. My code didn't know that the asset had stayed visible during the scroll event. To fix this, I simply keep track of the asset becoming visible.

If you've read the other posts then most of this should make sense already. To see this in action try the demo below.
