  Inertial Bounce Not Workin

  Posted by Gerald Collison on May 24, 2013 at 5:08 pm

  So I have copied and pasted the intertial bounce expression as an expression paramater into the postion field of a transparent .png image in my AE project and it isn’t working. Other expressions have worked but this one does not. I tried deleting the beginning of the expression w/ the title to no avail. This is a project w/ a Camera layer, 1920×1080. I can’t figure out why this won’t work!!! Every where I read everyonesays how great it works. Below is the expression. Any ideas???

  // Inertial Bounce (moves settle into place after bouncing around a little)
  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);
  amp = .05;
  freq = 4.0;
  decay = 2.0;
  value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
  }else{
  value;
  }
