  Expression for Digital 24 Hours clock

  Posted by Gilben on October 14, 2005 at 1:02 pm

  I am looking for a smarter way to build a count down 24 hours clock.
  I couldnt find the right plugin for this (the text number effect – is not good for 24 hours count down and has no 100/th of a sec.)
  Doing this with key frames seem to me no too effecient.

  I was thinking maybe anyone of you is familiar with plug in or if it could be done with animation Expression.

  Tnx for any help

  24 hour count down clock (expression for text layer source text):

  // 24 hour count down clock

  beginHr = 23;
  beginMin = 59;
  beginSec = 59;
  beginHun = 0;

  beginTime = (beginHr*60 + beginMin)*60 + beginMin + beginHun/100;

  function digits(myVal,myNumDigits){
  var s = myVal.toString();
  while (s.length < myNumDigits) s = '0' + s; return s; } currTime = beginTime - time; hr = digits(Math.floor(currTime/3600),2); min = digits(Math.floor((currTime%3600)/60),2); sec = digits(Math.floor(currTime)%60,2); hun = digits(Math.floor(currTime%1*100),2); hr + ":" + min + ":" + sec + "." + hun Dan

  You’d think I’d have learned by now to always try it before posting. This should work better:

  beginHr = 3;
  beginMin = 0;
  beginSec = 1;
  beginHun = 0;

  beginTime = (beginHr*60 + beginMin)*60 + beginSec + beginHun/100;

  function digits(myVal,myNumDigits){
  var s = myVal.toString();
  while (s.length < myNumDigits) s = '0' + s; return s; } currTime = beginTime - time; hr = digits(Math.floor(currTime/3600),2); min = digits(Math.floor((currTime%3600)/60),2); sec = digits(Math.floor(currTime)%60,2); hun = digits(Math.floor(currTime%1*100),2); hr + ":" + min + ":" + sec + "." + hun Dan

  Dan/Anyone

  what is taking place here in your expression:
  function digits(myVal,myNumDigits){
  var s = myVal.toString();
  while (s.length < myNumDigits) s = '0' + s; return s; } i can follow the rest but am having trouble with what "function" is performing (adobe help, wasnt) then waht is the digits command accomplishing... s i take it is getting the length of myVal i think i can figure it from there... just am not sure what is happening at the beginning... i have to write a clock that starts at a specific point and stops at a specific point over a specified period... i.e. clock starts at 30.0 seconds and over 2 second climb to 43.14 seconds. thanks,
