  Markers to trigger per-word reveal

  Posted by Thomas Hannen on April 18, 2022 at 5:37 am

  I’d like to write an expression to trigger each word in a text layer to appear every time a marker is present on the layer- (progressively revealing more words as more markers are passed on the timeline).

  I’ve found this expression which triggers per character:

  c = thisLayer;
  count = 0;
  for (i = 1; i <= c.marker.numKeys; i++){
  if (c.marker.key(i).time > time) break;
  count++;
  }
  var result = value.substring(0, count); // trim 
  resultc = thisLayer;
  count = 0;
  for (i = 1; i <= c.marker.numKeys; i++){
  if (c.marker.key(i).time > time) break;
  count++;
  }
  var result = value.substring(0, count); // trim 
  result
  

  But I can’t work out how to modify it to work per-word. Any ideas?

  Many thanks,

  Tom

  Hi Tom. You can try this. But this will only check spaces as word differentiators, not newlines.

  c = thisLayer;
  count = 0;
  for (i = 1; i <= c.marker.numKeys; i++) {
      if (c.marker.key(i).time > time) break;
      count++;
  }
  var result = value.split(" ").slice(0, count).join(" ");
  result;

  Hey Tom, check out this thread. I believe the last expression will do what you’re asking. Cheers!
