  Referencing Layer Name based on integer

  Posted by Marcus Round on August 8, 2014 at 2:38 pm

  I had trouble coming up with a descriptive title for this post, but here’s my problem:

  Let’s say I have a bunch of layers named like so:

  Penguin 1
  Penguin 2
  […]
  Penguin 49
  Penguin 50

  etc.

  Now let’s say I have a variable that could return anything from 1 to 50. Call it “myVar”.

  I would like to reference a particular Penguin layer based on the result of myVar. If myVar is 30, I want the expression to be linked to Penguin 30; if myVar is 17, I want to link to Penguin 17.

  so for example,

  myPos = thisComp.layer(“Penguin ###”).transform.position;

  where ### is replaced by the integer value of myVar.

  Is this possible?
  Thanks

  Something like this:

  thisComp.layer(“Penguin ” + Math.round(myVar)).transfrom.position;
