  Looping Expression

  Posted by Gigi Marzo on May 28, 2020 at 2:13 pm

  Hi, I’m approaching to world of animation. So I’d like to loop an expression.
  I’ll try to be clearer,
  I have this expression (bounce, to apply to scale and/or position) and I want to loop (cycle) it.

  amp = .06;
freq = 2;
decay = 7;

  n = 0;
  if (numKeys > 0){
  n = nearestKey(time).index;
  if (key(n).time > time){
  n--;
  }
  }
  if (n == 0){
  t = 0;
  }else{
  t = time - key(n).time;
  }

  if (n > 0){
v = velocityAtTime(key(n).time - thisComp.frameDuration/10);
value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
}else{
value;
}

  and I’d like to loop with simple expression like that:

  loopOut ("pingpong")

  How I do it?

  Thank u in advance 🙂

  Simple method would be pre-comp the layer and apply keyframe on time-remapping and apply loopOut() to time-remapping.
