  • For loop to count layers not behaving as it should

    Posted by Doc Byrne on March 19, 2024 at 11:03 am

    Hi folks,

    I’m working on a project and I need to count the number of layers with a specific name and display it as a number on screen. I’ve been using a for loop but unfortunately, I can’t quite get it right and I have the feeling I’m missing a condition in the code but I can’t figure out what it is.

    When I apply the following code to a text layer, it displays the correct number when I add or delete a layer called Depth provided it happens below the text layer. But if I add or delete layers above the text layer, the number increases or decreases the number, regardless of what the layer is called.

    I know it’s probably something obvious but I’m stumped. Can anyone help please?

    var result = 0;

    for (var i = 1; i <= thisComp.numLayers; i++) {

    var compLayer = thisComp.layer(i);

    var layerName =;

    if (layerName == "Depth") {

    Hi! You’re almost there, but instead of adding the layer index i to result, you should add 1 each time you find a layer named “Depth”. Also, remove the break statement to ensure the loop continues to check all layers even if your condition is met.

    That’s brilliant! Thanks a million for this, Julian. Can’t believe I got an i and a 1 confused 🤦‍♂️

    It’s running perfectly now.
