  Numbers…

  Posted by Mike Moon on January 28, 2010 at 5:15 pm

  Hello cows,

  I know, I know, there are tons of posts relating to numbers counting up with various methods to approach it. But the problem I’m having is having it count slow to fast.

  This is the script I was using,

  startVal = 10934;
  endVal = 10982
  ;
  dur = 15.24
  ;

  val = linear(time,0,dur,startVal,endVal);
  s = “” + (0 + Math.floor(val));

  I want the end value to be higher of course maybe to like 50,000?

  Thanks guys

  You want it to accelerate as it counts, going from 10934 to around 50000 in 15.24 seconds, is that correct?

  Play around with this and see if it’s close to what you’re after:

  startVal = 10934;
  rate = .67;

  val = startVal + Math.exp(time*rate) – 1;
  s = “” + Math.floor(val);

  Adjust “rate” to change the result at a particular time.

  I think that works just great. Thanks for your help. Btw is there any books you would suggest to help me learn how to understand scripts in AE?

  If by “scripts” you mean expressions, Marcus Geduld’s book is a really good place to start. If you really mean scripts, then there really isn’t anything I’m aware of that’s better than Adobe’s After Effects Scripting Guide.

  Oh, and in either case, a good JavaScript reference will be useful too.
