  Hair overshoot for a character

  Posted by Zoltán Riskó on September 13, 2017 at 7:32 pm

  Hey guys,

  I would like to add an overshoot effects for my character’s hair by expression. I found Dan’s awesome keyframe overshoot script which is awesome but i would like to modify it a little bit.

  Here is my result now, but not perfect:

  Now the hair has 3 puppet pins which are linked to 3 null objects. The null objects have a hierarchy by code so i need to move the parent only.
  But i can only achive the overshoot if ad keyframes to the second and the third null objects too but i want to avoid it.

  Is there any trick to add a parent or something like that to the code so i don’t need to add keyframes to the second and third null object but achive an overshoot effect?

  For example: ( sorry I’m not too good with expressions 😛 )

  freq =thisComp.layer(“Settings”).effect(“Freq”)(“Slider”);
  decay = thisComp.layer(“Settings”).effect(“Decay”)(“Slider”);
  myparent=thisComp.layer(“1”).transform.position;

  n = 0;
  if (myparent.numKeys > 0){
  n = myparent.nearestKey(time).index;
  if (key(n).time > time) n–;
  }
  if (n > 0){
  t = time – key(n).time;
  amp = velocityAtTime(key(n).time – 0.01);
  w = freq*Math.PI*2;
  thisComp.layer(“1”).transform.position + value + 15*(amp*(Math.sin(t*w)/Math.exp(decay*t)/w));
  }else
  thisComp.layer(“1”).transform.position+value

  Thanks guys (and sorry for my english )
