  scale dependent on distance

  Posted by Rikard Lassenius on May 8, 2017 at 6:47 am

  hi been struggling with a challenge that should be really simple. want to have o large number of short lines turning towards a null, and becoming shorter the closer the null gets.

  made a line as a shape layer, and gets it to turn toward the null with the lookAt expression.

  but how do i make it scale the Y scale? managed to affect eg opacity using the lenght attribute, but not the scale. how do i do it. thanks a lot!

  length(thisComp.layer("line_01").position, thisComp.layer("NULL").position)

  You might have to multiply d by some factor to get the right relationship, but maybe something like this:

  d = length(thisComp.layer(“line_01”).position, thisComp.layer(“NULL”).position);
  [value[0],d]
