  Advanced Time Expresion

  Posted by Augusto Keltika junior on May 23, 2017 at 3:02 am

  Hi there,

  I’m creating a countdown at 25fps and I’d like it to spin 360° with ease on Y axis every 19 frames, how would I go with that?
  I tried clamp, math.sin and other time expressions on the forum but nothing is quite doing what I am after.
  I appreciate your help, thanks.

  This should work:

  t0 = inPoint;
period = 19; // frames
spinDur = 4; // frames
phase = 2; // frames

  t = timeToFrames(time-t0)-phase;
  n = Math.floor(t/period);
  t%=period;
  if (t<0) t+= period;

  n*360 + ease(t, 0, spinDur, 0, 360);
