  Translate AE expression to Xpresso: bacteria random jumps

  Posted by Corrado Carlevaro on July 31, 2010 at 10:57 am

  Hi,
  this is an After Effects expression to make an object jump in a random position at fixed intervals, kind of chaotic movements of bacteria seen with microscope, how would you translate it in Xpresso?
  Thanks in advance

  moveTime = .2;
  holdTime = 3;
  minDelta = [-2,-4,0];
  maxDelta = [2,-6,0];

  seg = Math.floor(time/(moveTime+holdTime));
  seedRandom(index,true);
  prevDelta = [0,0,0];
  for (i = 0; i < seg; i++) prevDelta += random(minDelta,maxDelta);
  delta = random(minDelta,maxDelta);
  t = time % (moveTime+holdTime);
  value + prevDelta + linear(t,holdTime,holdTime+moveTime,0,delta)
