  Detect Shape Layer Path

  Posted by Michael Ponch on July 10, 2024 at 1:30 pm

  Hi everyone!

  I need an AE expression that detects if a layer is a Shape Layer AND has at least a path.

  I appreciate any help.

  Thanks in advance!

  Michael

  Hi Michael,

  you can check if a layer is a shape layer like this:

  isShapeLayer = thisLayer.content instanceof Group;
  isShapeLayer; // Returns 1/true or 0/false

  Regarding the path detection: do you explicitly need to check for Bezier Paths, or would it be enough to check for any existing content (groups, primitives, paths)?

  The latter could look like this:

  hasContent = thisLayer.content.numProperties > 0;
  hasContent; // Returns 1/true or 0/false

  Both combined:

  L = thisLayer;
  isShapeLayer = L.content instanceof Group;
  hasContent = L.content.numProperties > 0;
  isShapeLayer && hasContent; // Returns 1/true or 0/false
