  add 1 to a counter whenever time passes a keyframe

  Posted by Padraic Rapp on March 12, 2018 at 11:34 am

  Hello,

  I am trying to make a counter that shows the keyframe index and ticks up one whenever the current time passes a keyframe on a target layer.

  I am failing to compare the current time with the time of the next keyframe but maybe someone can help me out.

  Thank you!

  Here’s an example that increments each time the current time reaches a position keyframe on the “target” layer:

  
p = thisComp.layer("target").position;
n = 0;
if (p.numKeys > 0){
n = p.nearestKey(time).index;
if (p.key(n).time > time) n--;
}
n
