generate sequential number level

[Ciccillotto]

 I work with many levels and I would like it to generate a progressive number for each level I create. for example, if the layer is called face, the next layer will be called face 1, the other layer face 2, and then onwards. I hope for help.

This does the job:

var c = 0;
var layName = "";

iterLayers(app.activeDocument);

function iterLayers(l) {
    for(var i=0; i<l.layers.length; i++) {
        var curLay = l.layers[i];
        app.activeDocument.activeLayer = curLay;
        
        if(layName == "") {
            layName = curLay.name;
        }

        if(curLay.typename == "LayerSet") {
            iterLayers(curLay);
        } else {
            if(c != 0) {
                curLay.name = layName + " " + c;
            }
            c++;
        }
    }
}

What is your expectation?

Are you looking for a script to rename selected layers? For example, let's say that you had 4 layers selected that all were called "face".... Would the script rename them as: face, face 1, face 2, face 3 

Or do you want a script to make a new layer based on the current single active layer name? So if the current layer was named face 2, then running the script would create a new layer named face 3

Are these always  standard art layers, or adjustment or groups or other kinds?

Can you post a screenshot of your layer panel so a better understanding of the structure can be as ascertained?

Stephen the layer with the name face exists, I would like to create a button that only adds the sequential number to the layer. I hope I have explained myself. @GNDGN Now I'm not at home I'll try it tomorrow and let you know, anyway thanks for the help

By @Ciccillotto

With only a single layer selected, I don't know how Photoshop would know what sequential number to apply... Short of using the  crystalBall(); function – the script would need to loop over all the layers, get the layer names, find all matching layers and what the last number was in the matching layer, and then increment the number.

Select all layers with the same layer name.

Run this script. Looking at the code, I think that it came from Paul Riggott. I have updated the code to use the current user interface colour scheme and to auto-populate the replace field with the top selected layer name + space:

This is fine for what I need to do,
