Smoothing values of another layer

Jan 30, 2012 2:59 PM

Tags: #help #smooth #expression #damp #damping

I have Layer A which has a standard wiggle on it. I pickwhip the position of Layer B to copy Layer A's.

 

But now I want Layer B's motion to be a damped — as if Layer B is copying Layer A's movement, but Layer B is stuck in molasses.

 

Can I use the  smooth(width = 1, samples=5, t=time) function to accomplish this? Is there a better way?  How could I also add a slight time delay to Layer B so it's a few frames behind Layer A's motion?

    Pretty much like you would expect:

     

    delay = 3*thisComp.frameDuration;

    thisComp.layer("Layer A").transform.position.smooth(width = 1, samples=5, t=time-delay)

    Ah!  Smooth goes on the end of a property! Way simpler that I imagined.
