Help need edit script layer shuffle

[blasta20445892]

Hi,

I have some code which can shuffle layer

app.activeDocument.suspendHistory("Randomize Layers", "main ()");  

function main () {
    if (documents.length > 0)
    {
        // Count number of layers in document
        var nLayers = activeDocument.layers.length;
        if (nLayers > 1) { // Needs at least two movable layers to be useful
            layersAll = activeDocument.layers;
            // I run through twice, because it seems to come out much more random-looking when I do
            for (var j=0;j<1;j++) {
                for (var i=0;i<nLayers;i++) {
                    var whichLayer = Math.floor(Math.random()*nLayers);
                    if (layersAll[whichLayer].isBackgroundLayer==false) {
                        activeDocument.activeLayer = activeDocument.layers[whichLayer];
                        app.activeDocument.layers[whichLayer].move(activeDocument,ElementPlacement.PLACEATEND);
                    }
                }
            }
            alert ("Reordered "+i+" layers");
        }
        else {
            alert ("Not enough layers to randomize");
        }
    }
    else {
        alert ( "You must have at least one open document to run this script");
    }
}

the problem is cannot selected by layer, so it will shuffle all layer, can someone help to edited the script, so it will shuffle by selected layer, Thankss

Are you saying that you want to select several layers and only randomize those selected layers within just the selected layers or randomize them within all the layers?

[blasta20445892]

like this chuck, only the selected layer,and when run the script, it will random shuffle

[Chuck Uebele]

You can try this script. It will only shuffle the layers in the layer stack. It will not move the actual position of the layers' contents. Thanks to r-bin for the base structure of this script.

Edit: just noticed that your example layers are clipped. This will remove the clipping.

var listA = new Array()
var r = new ActionReference();
r.putProperty(stringIDToTypeID("property"), stringIDToTypeID("targetLayersIndexes"));
r.putEnumerated(stringIDToTypeID("document"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));

var list = executeActionGet(r).getList(stringIDToTypeID("targetLayersIndexes"));  

if (list.count < 1) throw("Two or more layers needed");
var listNum = list.count

for(var i=0;i<listNum;i++){
    var r = new ActionReference();
    r.putProperty(stringIDToTypeID("property"), stringIDToTypeID("targetLayersIndexes"));
    r.putEnumerated(stringIDToTypeID("document"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));

    listA = executeActionGet(r).getList(stringIDToTypeID("targetLayersIndexes"));        
    
    var num1 = Math.floor(Math.random()*listNum);
    var num2=num1;

    selectPair (num1, num2)
    }


function selectPair(lay1,lay2){

    var idx0 = listA.getReference(lay1).getIndex();
    var idx1 = listA.getReference(lay2).getIndex();

    var r = new ActionReference();
    r.putProperty(stringIDToTypeID("property"), stringIDToTypeID("targetLayersIDs"));
    r.putEnumerated(stringIDToTypeID("document"), stringIDToTypeID("ordinal"), stringIDToTypeID("targetEnum"));

    var list2 = executeActionGet(r).getList(stringIDToTypeID("targetLayersIDs"));  

    var id0 = list2.getReference(lay1).getIdentifier();
    var id1 = list2.getReference(lay2).getIdentifier();

    set_layer_index(id0, idx1);    
    set_layer_index(id1, idx0);  
}

function set_layer_index(id, idx)    
    {    
    try {    
        var d = new ActionDescriptor();    
    
        var r1 = new ActionReference();    
        r1.putIdentifier(stringIDToTypeID("layer"), id);    
        d.putReference(stringIDToTypeID("null"), r1);    
    
        var r2 = new ActionReference();    
        r2.putIndex(stringIDToTypeID("layer"), idx);    
        d.putReference(stringIDToTypeID("to"), r2);    
    
        executeAction(stringIDToTypeID("move"), d, DialogModes.NO);    
        }    
    catch (e) { throw(e); }    
    }

Thanks Chuck, its works well,

but how to maintain the clipping mask to be still in there,

because I need a clipping mask to be there.

[Chuck Uebele]

I'll have to research that. I could do it way that takes longer, but there might be a shorter method using AM code, which I'm not that good at.

[blasta20445892]

is there a script that can make a clipping mask from the selected layer, because after using a script from you the layer is still selected,

[Chuck Uebele · Accepted solution]

Okay, this should keep the layers clipped.

var doc = activeDocument;
var listA = new Array()

var layList = getLayersIdx ();
if (layList.count < 1) throw("Two or more layers needed");
var listNum = layList.count

    listA = getLayersIdx ();      
    
    var num1 = Math.floor(Math.random()*listNum);
    var num2=num1;
    while(num2==num1){
        var num2 = Math.floor(Math.random()*listNum);
        }
    
    selectPair (num1, num2)
    }

reClip ();

function selectPair(lay1,lay2){

    var idx0 = listA.getReference(lay1).getIndex();
    var idx1 = listA.getReference(lay2).getIndex();
