  Random expression in frames

  Posted by Patrick Murphy on February 7, 2017 at 7:50 pm

  Hi there!

  I have this script but instead of hold time in seconds, I’d like it to be hold time in frames.
  I’ve looked around and tried some things but I’m still a bit of a noob.
  Thanks!

  Here’s the expression I have to convert

  hold = .5; //time to hold each number (seconds)
  min = -1;
  max = 1;

  seed = Math.floor(time/hold);
  seed_random(seed,true);
  random(min,max)

  you can convert a frames value to time, or a time value to frames… i think i’d use the first option like this

  hold = 15; //time to hold each number (frames)
  min = -1;
  max = 1;

  seed = Math.floor( time / framesToTime( hold ) );
  seed_random( seed, true );
  random( min, max )
