Layer Sets (groups)

Hi fellas. It's been a while!

I tend not to use groups (layer sets) myself, but other people do. I've got several scripts that loop over all layers in a psd and then peform various tasks.

Of course they fall over if layersets are involved; so I need to change that.

To test this out I wrote a script and made a simple psd; New document (any size), background, one layer (called "layer 1") and another layer ("layer 2") which is in a layer set ("a_group")

I've got a basic script here that loops through all layers (or so I thought)

<code>

var srcDoc = app.activeDocument;

var numOfLayers = srcDoc.layers.length;

for (var i = numOfLayers -1; i >= 0  ; i--)

{    var layerName = srcDoc.layers.name;

    // check for groups

    if (srcDoc.layers.typename == "LayerSet")

    {

    alert (layerName + " is a group")

    }

    else

    {

    alert (layerName + " is not in a group")

    }

</code>

The alert calls all layer names as it goes up the stack. It however misses out layer 2 (which is in a group) So what am I missing out?

Cheers

Correct answer c.pfaffenbichler

They are defined with unique names in upper case.

How would the action manager work with the script?

I think you need a function that calls itself, because Layers in LayerSets are children of the LayerSet and not the document.

var theLayers = collectLayers(app.activeDocument, []);
alert (theLayers.join("\n"));
////// function collect all layers //////
function collectLayers (theParent, allLayers) {
          if (!allLayers) {var allLayers = new Array} 
          else {};
          for (var m = theParent.layers.length - 1; m >= 0;m--) {
                    var theLayer = theParent.layers;
// apply the function to layersets;
                    if (theLayer.typename == "ArtLayer") {
                              allLayers.push(theLayer)
                              }
                    else {
                              allLayers = (collectLayers(theLayer, allLayers))
// this line includes the layer groups;
                              allLayers.push(theLayer);
                              }
                    };
          return allLayers
          };

    The script reports a list of layers and layer sets from the active document.

    How can this script check for a specific layer either as part of a layer set or stand alone layer in the active document?

    How are the Layers you are looking for defined?

    Anyway, Action Manager code would likely considerably faster.
