Is there a script to make specific attrubute changes to all layers in project?

Question

Hello, and thank for your time!
I have a project that contains a lot of comps with a lot of shape layers in each.
Is there a way to make global changes to stroke size property of shape layers, for example from 0px to 1px?
Thanks.

This should work for you. Towards the very bottom is the code line that you can set for the width value. It will look like this a.property(i).setValue(1.0); //STROKE WIDTH VALUE
//START
var proj = app.project;
var comps = getAllProjectComps(proj);
for(var i=0; i<comps.length; i++){
          searchLayersAndChangeVal(comps[i]);
function getAllProjectComps(sourceFolder){
          try{
                     var itemAry, itemsInFolder, itemsInFolderLength;
                     itemAry = new Array();
                     itemsInFolder = sourceFolder.items;
                     itemsInFolderLength = itemsInFolder.length;
                     for(var i=1; i<=itemsInFolderLength; i++){
                               if(itemsInFolder[i] instanceof CompItem){
                                        itemAry[itemAry.length] = itemsInFolder[i];
                     return itemAry;
          }catch(err){alert("Error at line# " + err.line.toString() + "\r" + err.toString());}
function searchLayersAndChangeVal(compSource){
          var layerCollect = compSource.layers;
          var layerCollectLength = layerCollect.length;
          var curLayer, props, propsLength;
          var propObjAry = new Array();
          for(var l=1; l<=layerCollectLength; l++){
                    curLayer = layerCollect[l];
                    if(curLayer instanceof ShapeLayer){
                              getStrokeWidthAndChangeValue(curLayer);
function getStrokeWidthAndChangeValue(a){
          try{
                    var propLength = a.numProperties;
                    for(var i=1; i<=propLength; i++){
                              if(a.property(i).matchName == "ADBE Vector Stroke Width"){
                                        a.property(i).setValue(1.0);          //STROKE WIDTH VALUE
                              if(a.property(i).numProperties > 0){
                                        getStrokeWidthAndChangeValue(a.property(i));
          }catch(err){alert(err.line.toString() + "\r" + err.toString());}
//END
