  Ramping the numbers expression

  Posted by Will Eccleston on August 27, 2012 at 7:15 pm

  Is there a way to very smoothly ramp into a number counter expression? Start counting slowly and ramp up over time? I’m using an expression that I think is Dan’s originally, (not sure). Any help very much appreciated and sorry if this has been covered, I swear I searched. I want to take a couple or three seconds to get into the mid-hundred-thousands and then increase the pace so that by 5 or 6 seconds I’m in the trillions. Here’s what I’m using, no ramp:

  numDecimals = 0;
  commas = true;
  dollarSign = true;
  beginCount = 00;
  endCount = 222222187652003;
  dur = 35;
  t = time – inPoint;
  s = linear (t, 0, dur, beginCount, endCount).toFixed(numDecimals);
  prefix = “”;
  if (s[0] == “-“){
  prefix = “-“;
  s = s.substr(1);
  }
  if(dollarSign) prefix += “$”;
  if (commas){
  decimals = “”;
  if (numDecimals > 0){
  decimals = s.substr(-(numDecimals + 1));
  s = s.substr(0,s.length – (numDecimals + 1));
  }
  outStr = s.substr(-s.length, (s.length-1)%3 +1);
  for (i = Math.floor((s.length-1)/3); i > 0; i–){
  outStr += “,” + s.substr(-i*3,3);
  }
  prefix + outStr + decimals;
  }else{
  prefix + s;
  }

  Try replacing the line that defines variable s with this:

  s = linear (t*t*t, 0, dur*dur*dur, beginCount, endCount).toFixed(numDecimals);

  Seems to have worked. Thank you! I wish I could download your understanding of this stuff. I can learn programming languages, and have before, but just being able to comprehend the operations that need to take place to achieve the goal, that’s something else entirely.
