  expression counting from 0% to 100% and start at 0 again.

  Posted by Sarah Schela on May 17, 2012 at 3:50 pm

  Hello,

  I looked through the forum for an answer to this question, but haven’t found one.
  So as it is written in the title I am looking for an expression which counts from 0% to 100% and starts at 0% all over to 100% again in a loop.

  I just found this expression saying that the counter runs from 0% to 100% but then decreases to 0% and starts counting upwards to 100% again.

  freq = 1;
  50*(1 – Math.cos(freq*time*Math.PI*2))

  so I believe there must be some kind of “if” like “if the number reaches 100 start at 0 again” or something. but I have not much experience so I hope for some advices!

  this should do it. just set the freq value to the loop point.

  freq = 1; // value in seconds
  timeToFrames(time % freq) + “%”

  i also added the % sign in there… if you don’ need that delete the + “%”.

  i’m sorry, that really doesn’t work quite right… i should test before i post.

  this should do it though:

  freq = 2; // value in seconds
  Math.round(linear(time % freq, 0, freq, 0, 100)) + “%”

  If you’re just looking for something that counts from 0 to 100 and then starts over, this might work for you:

  rate = 30;
  Math.round((time-inPoint)*rate%101)

  Set the rate to whatever makes sense for your application.
