  • Create Script to Add loopOut() Expression to Layer

    I was told to post this here so I can get some better help with this script I am trying to write. I am a beginner with scripting right now and I am trying to start off with just creating simple shortcut scripts that I can use in AE.

    One that I am trying to make is a script that will add the loopOut() expression to the position of a selected Layer that is already keyframed.

    Here is the code I have so far (see below)

    Any help is greatly appreciated.


    var myComp = app.project.activeItem;
    var myLayer = myComp.selectedLayers[0];
    var prop = myLayer.transform.position;
    prop.expression = "loopOut("cycle")";
    prop.expressionEnabled = true;

    I think you’ll need to change the line with the expression, like this:

    prop.expression = ‘loopOut(“cycle”)’;

    but otherwise I think it will work.
