  • Change text properties using ExtendScript

    Posted by George Beridze on January 16, 2024 at 2:22 am

    Hey guys,

    I know this is an expressions forum category and I have a question about Extendscript, but maybe I can still post about it?

    So, I’m trying to change one of the text properties here.

    I can successfully change Anchor Point Grouping (see here), using the code below:

    var thisComp = app.project.activeItem;
    var curLayer = thisComp.selectedLayers[0];
    textAnchorPointGrouping = curLayer.property("Text").property("More Options").property("Anchor Point Grouping");
    textAnchorPointGrouping.setValue(1);

    But, when I want to change Based On (see here) property under Range Selector, it’s not working and i’m getting undefined is not an object error (see here). Below is the code:

    var thisComp = app.project.activeItem;
    var curLayer = thisComp.selectedLayers[0];
    textAnchorPointGrouping = curLayer.property("Text").property("Animator 1").property("Range Selector 1").property("Advanced").property("Based On");
    textAnchorPointGrouping.setValue(1);

    Not sure what I’m doing wrong and any suggestions would be helpful!

    Thanks!

    Try changing the 3rd line to this:

    textAnchorPointGrouping = curLayer.property("Text").property("Animators").property("Animator 1").property("Selectors").property("Range Selector 1").property("Advanced").property("Based On");

    Legend!

    Works perfectly – You just saved me a lot of hours of manual work.

    One more question, please:

    If I have several layers selected (layers are duplicates of each other, each one has the same exact names on text animators), the code doesn’t work on all selected layers – it only works on the first selected layer, not the rest.

    How would I fix that?

    Try it this way:

    var thisComp = app.project.activeItem;
    var selectedLayers = thisComp.selectedLayers;
    for (var i = 0; i < selectedLayers.length; i++){
    textAnchorPointGrouping = selectedLayers[i].property("Text").property("Animators").property("Animator 1").property("Selectors").property("Range Selector 1").property("Advanced").property("Based On");
    textAnchorPointGrouping.setValue(1);
    }

    Here I’m getting “null is not an object” error on textAnchorPointGrouping, here’s what’s happening

    My guess would be that one of your selected layers doesn’t have the same Animator setup as the others, so that the property spec selectedLayers[i].property(“Text”).property(“Animators”)…. doesn’t actually exist.

    Thank you for solving this, Dan!
