Photoshop action to make 1 random layer visible within each group - photoshop

Question

I'm trying to use Photoshop actions to generate randomized images that are composed of a random sampling of layers. I have 3 groups of layers which are ALL not visible by default.
Within each group I'd like to make 1 random layer visible (in total there will be 3 "on" layers)
Export the whole thing as a .png file.
Repeat n times
Example Groups/Layers:
[FRUITS]
* [Apples]
* [Oranges]
* [Pears]
* [Bananas]
* [Kiwis]
[VEGGIES]
* [Asparagus]
* [Cilantro]
* [Eggplant]
[MEATS]
* [Beef]
* [Pork]
All layers are hidden by default, but when I play an action, I might get the following result (visible layers):
Image1: [Apples] [Eggplant] [Pork]
Image2: [Pears] [Asparagus] [Pork]
Image3: [Kiwis] [Cilantro] [Beef]

Answer 1

Here Is my script, but don't forget to do the following steps before running it:
Hide All Layers and Groups Except Background.
Save Your PSD.
Close and then reopen.
Now you are ready to rock.
Features
Make Unlimited Patterns you want from your groups.
Saved All Patterns As Indexed separate PNG in Separate Folder named PNG.
Watch GIF (below) to understand more:
function Visible() {
var Grps = app.activeDocument.layerSets; // loops through all groups
for(var i = 0; i < Grps.length; i++){
var tmp = app.activeDocument.layerSets[i].layers.length;
app.activeDocument.layerSets[i].visible=true;
var groupChildArr = app.activeDocument.layerSets[i].layers;
var randLays = Math.floor(Math.random() * tmp);
groupChildArr[randLays].visible = true;
Save();
}
Revert();
}
function Save() {
var outFolder = app.activeDocument; // psd name
var outPath = outFolder.path;
var fName = "PNG"; // define folder name
var f = new Folder(outPath + "/" + fName);
if ( ! f.exists ) {
f.create()
}
var saveFile = new File(outPath + "/" + fName +"/" + "Pattern_" + num + ".png");
pngSaveOptions = new PNGSaveOptions();
pngSaveOptions.interlaced = false;
app.activeDocument.saveAs(saveFile, pngSaveOptions, true, Extension.LOWERCASE);
}
// Original code - revert function does not work
// for some users
//function Revert(){
// var idslct = charIDToTypeID( "slct" );
// var desc300 = new ActionDescriptor();
// var idnull = charIDToTypeID( "null" );
// var ref163 = new ActionReference();
// var idSnpS = charIDToTypeID( "SnpS" );
// ref163.putName( idSnpS, "test.psd" );
// desc300.putReference( idnull, ref163 );
// executeAction( idslct, desc300, DialogModes.NO );
//}
function Revert(){
var idRvrt = charIDToTypeID( "Rvrt" );
executeAction( idRvrt, undefined, DialogModes.NO );
}
var count = prompt("How many patterns you want","");
for (var x=0 ; x<count;x++){
var num = x+1;
Visible();
}
