Thank you Nick. I have looked online and seen a few Jquery scripts that check if one element overlaps another. But in my case I need something to fire, such as a timeline, when the bounce is fired.
I have looked at that script, downloaded, opened, and previewed, but it does not work, and so not draggable. Just seems static.
Would I need to put a listener on scene load on any class named 'raindrop' and so when it over laps another element it fires another function, timeline ? Lots of other scripts i have seen have other physics so not sure it would not just confuse things. When I purchased this, I thought it would of had collisions as a basic function to be honest. A little disappointed.
