  layer markers and expressions

  Posted by Sam Young on June 6, 2006 at 11:13 pm

  i’ve read the archives, including dan ebberts’ “synchronizing animation to audio” tutorial, but i haven’t found any simple solution to my problem.

  i’ve got a bunch of layer markers on a layer. i want an expression on that layer to generate a new random number every time a layer marker is reached.

  is there a way to do this?

  thanks in advance

  This should give you a new random number between 1 and 100 at each marker;

  minNum = 1;
  maxNum = 100;

  n = 0;
  if (marker.numKeys > 0){
  n = marker.nearestKey(time).index;
  if (marker.key(n).time > time){
  n–;
  }
  }

  seedRandom(n,true);
  random(minNum,maxNum)
