  counting expression

  Posted by Justin Young on May 26, 2010 at 3:33 am

  I’m trying to use an expression I found here and get it to work with a variable value, but I keep getting errors.

  Any ideas on why it’s not working?

  startTime = 1.5; //in seconds
endTime = 5; //in seconds
startValue = 0;
endValue= comp("INFO").layer("showNumber").text.sourceText);
linear (time, startTime, endTime, startValue, endValue)

  Hi Justin.., i think using of “parseInt()” will solve your problem…

  add the bold line in your code..

  startTime = 1.5; //in seconds
  endTime = 5; //in seconds
  startValue = 0;
  sTextValue=parseInt(comp(“INFO”).layer(“showNumber”).text.sourceText));
  endValue=sTextValue ;
  linear (time, startTime, endTime, startValue, endValue)

  and check it out….

  I actually got it working now. The semi colon at the end was screwing it up.

  beginTime = 0;
  endTime = 2;
  startVal = 100;
  endVal = parseInt(comp(“INFO”).layer(“showNumber”).text.sourceText)
  Math.round(linear(time,beginTime,endTime,startVal,endVal))
