  Referencing a file through 2 layers of Scripts in After Effects

  Posted by Inch Bunmi on July 28, 2015 at 11:58 am

  Hi Guys,

  I am having an issue referencing a file through 2 AE scripts. Here is what I mean:

  Script1 (The actual Script that you run):
  scriptFile = new File(“C:/Scripts/Script2.jsx”);
  $.evalFile(scriptFile);

  Script2:
  //Create Null//
  var myNull = curItem.layers.addNull(curItem.duration);
  myNull.name = “Scale_Null”;
  //Change Null Scale to an Expression//
  var ActionFile = File(“Scale.js”);
  var ActionFileText = ActionFile.open(“r”);
  var ActionFileTextRead = ActionFile.read();
  curItem.layer(“Scale_Null”).scale.expression = ActionFileTextRead;

  Scale.js:
  A = thisComp.width;
  [A, A];
  _____________________________

  What I want:
  1. Script1 is supposed Launch Script2
  2. Script2 is supposed to create a Null and then reference a .js file which will be used as the expression for the Null’s scale.

  Problem:
  1. Script1 Launches Script 2 fine.
  2. Script2 creates the null.
  3. Script2 refuses to reference the .js file
  4. BUT When I launch Script2 directly (bypassing script1), The .js file is referenced and then used as the Null’s Expression.

  Please Help

  Perhaps the working directory is different in these two cases? What is the path to Scale.js?

  I figured and solved the problem.

  Script2 was missing a file location. So by adding “c:/Scripts/” to the Script2 file, I was able to direct the file referencing.

  *All 3 files (Script1, Script2 & Scale.js) are placed in the same directory.

  Thank you for the response.
