  Shape Layer’s Repeater to influence Ellipse Size

  Posted by Pedro Amaral on August 15, 2016 at 6:23 pm

  Hi,

  I have a circular shape layer with a repeater (3 copies on scale).
  As I increase the scale size of the repeater I would like the shape layer’s size to increase that same amount.
  Now to complicate things a little I have an array of other shape layers that are picking up animated values from LEAD layer on top and a delay system controlled through slider controls on a Null object.

  My expression for the shape layer size, for example, looks like this:

  var frameDelay = thisComp.layer(“CONTROLER”).effect(“Delay Pos”)(“Slider”) ;
  var delay = framesToTime(frameDelay) ;
  var itemAbove = thisComp.layer(index-1).content(“Ellipse 1”).content(“Ellipse Path 1”).size;
  var amountx = thisComp.layer(“CONTROLER”).effect(“Amount CircSize”)(“Slider”);
  var amounty = thisComp.layer(“CONTROLER”).effect(“Amount CircSize”)(“Slider”);
  var x = itemAbove.valueAtTime(time-delay)[0] + amountx;
  var y =itemAbove.valueAtTime(time-delay)[1] + amounty;

  [x,y];

  This is how the repeater scale looks like:

  var frameDelay = thisComp.layer(“CONTROLER”).effect(“Delay RepSize”)(“Slider”);
  var delay = framesToTime(frameDelay) ;
  var itemAbove = thisComp.layer(index-1).content(“Repeater 1”).transform.scale;
  var amountx = thisComp.layer(“CONTROLER”).effect(“Amount RepSize”)(“Slider”);
  var amounty = thisComp.layer(“CONTROLER”).effect(“Amount RepSize”)(“Slider”);
  var x = itemAbove.valueAtTime(time-delay)[0] + amountx;
  var y =itemAbove.valueAtTime(time-delay)[1] + amounty;

  [x,y];

  Any ideas on how I could add the increment on the Repeater’s Scale property to the Shape Layer’s Size?

  Thanks in advance!
