  Scale up to random value

  Posted by Assaf Tshuva on April 19, 2016 at 3:51 pm

  Hello,

  I have a very large stock of objects that I want each to scale from 0 up to a random size (something between 2-6 percent, for example), and stay there, instead of keyframing all of them.
  The animation length could be fixed for all (let’s say 1 sec), but each object should start at different time (I’ve seen some expressions that could make such animations but relied on the global time code).

  Thanks in advance.

  Like this maybe:

  maxDelay = 2;
  rampTime = 1;
  minVal = 2;
  maxVal = 6;
  seedRandom(index,true);
  delay = random(maxDelay);
  val = random(minVal,maxVal);
  linear(time,inPoint+delay,inPoint+delay+rampTime,0,[val,val])

  Worked perfectly (took down the delay parts, though), thank you.
  I still don’t get the linear expression…
