  Moving Expression or Turn on at a certain time

  Posted by Phil Lebeau on May 4, 2010 at 5:09 pm

  I have found some help on this but I cant get it right. I am new to expressions and quite honestly I should stay away from them – make my head spin:-)

  I need to have 3 words cascade down from each other. I am using the pendulum expression that Dan Ebbert so wonderfully shared. But once I move my layer to where I need the effect to happen, the effect is over. I posted a couple of pics so you can see my expression.

  Thanks for any help you can offer.

  First photo – expression works – second photo it doesn’t

  You Probably just need to change this:

  amplitude*Math.sin(veloc*time)/Math.exp(decay*time)

  to this:

  t = time – inPoint;
  amplitude*Math.sin(veloc*t)/Math.exp(decay*t)
