  random starting time

  Posted by Rikard Lassenius on March 20, 2009 at 1:09 pm

  hi, been hitting my head against for while + reading every possible forum aswell. but i can’t figure this out…

  have an animation with a cherry tree, and want to animate the flowers popping out in bloom. did the animation in a null layer (just a short “boioing!”-kind of scaling thing) and wanted to have that on all layers.
  thats no prob, of course. but how to write an expression that makes the flowers pop up randomly, whithin some limits?

  (i’m running AE CS3 on a Mac)

  thanks,

  Rikard

  Probably something like this:

  minDelay = 0;
  maxDelay = 2;
  seedRandom(index,true);
  delay = random(minDelay,maxDelay);
  thisComp.layer(“Null 1”).transform.scale.valueAtTime(time-delay)
