  After Effects Expression

  Posted by Bilal Arif on July 2, 2023 at 10:37 am

  var x = 0;

  var y = 2;

  var z = 10;

  I want var x value to be increased by 1 (x + 1) after every var y seconds untill time is equal to var z.

  What to do?

  Expressions don’t have memory, so variables don’t survive from one frame to the next, but you can calulate your x value based on the current time, like this:

  var x = 0;
  var y = 2;
  var z = 10;
  x += Math.floor(time/y);
  x = Math.min(x,z);

  or elapsed time since the layer’s in point, like this:

  var x = 0;
  var y = 2;
  var z = 10;
  x += Math.floor((time-inPoint)/y);
  x = Math.min(x,z);
