Hittest only working on the first instance

[njvan]

Hi again, in my codepen example - hittest works as expected but only in the first instance. What would be the recommended way to detect a collision with multiple dynamically created elements?

Hi njvan,

 

Calling hitTest like you are doing will only call it on the first .pad element and the first .note element. You would need to loop through each pad and each note to do it like you want. That's going to be a little wasteful, so it would be best to only check notes that are in the same track as the pad. To further optimize, you should only check notes that are active. Notice how I added an active class to the element right before it animates and remove it right after it animates.

 

If you need any help understanding what I did here, just let me know.

That's amazing! Adding the active class was genius. I had started down a rabbit hole of trying to get the currently animating element in the timeline. This is much simpler. Thank you so much, @OSUblake!
