  How to define sequence of layers from max to min

  Posted by Serge Druz on July 5, 2017 at 8:32 pm

  Thank you for all you help.

  For example I have 5 circles with random scale.
  is there any way to find out, which layer has max value. which second after max value, which third and so on till min layer.
  if I find out this i want to make
  max layer – 100% opacity
  second -80% opacity
  third – 60%
  fouth – 40%
  and fifth – 20%

  and then if scale randomly changes, it need to be update automaticly.

  I don’t even know if it possible, but I will be grateful for any help.
  Thank you.

  Assuming the layers are the top 5 layers in the stack, something like this might work:

  
s = scale[0];
vals = [20,40,60,80,100];
count = 0;
for (i = 1; i <= 5; i++){
if (index == i) continue;
if (s > thisComp.layer(i).scale[0]) count++;
}
vals[count]

  Unfortunately I don’t understand the code, but it works perfectly. It’s a kind of magic. Thank you very much for your help.
