“Butt Cap” to “Round Cap” with a Script (But it doesn’t work)

[Vincenzo Imbimbo]

Hi guys! I don’t know what i’m doing wrong, this should be working, anyone can help me?

I’m trying to change the “Butt Cap” of selected shape layers to “Round Cap” but i can’t figure it out why is not working, here is the code:

var project = app.project;
var comp = project.activeItem;

app.beginUndoGroup("Process");
var myLayers = comp.selectedLayers;
var myLayer;
for (var i = 0; i < myLayers.length; i++){
myLayer = myLayers[i];
if (myLayer instanceof ShapeLayer){
var myContents = myLayer.property("ADBE Root Vectors Group");
for (var j = 1; j <= myContents.numProperties; j++){
myContents.property(j).property("ADBE Vector Group").property("ADBE Vectors Group").property("ADBE Vector Shape - Group").property("ADBE Vector Shape").property("ADBE Vector Graphic - Stroke").property("ADBE Vector Stroke Line Cap").setValue(2);
}
}
}
app.endUndoGroup();

I make it work but only for 1 shape element of each shape layer, i want it to work in any shape layer no matter how much elements it has inside the Groups.

This is what it works:

var project = app.project;
var comp = project.activeItem;
app.beginUndoGroup("Process");
var myLayers = comp.selectedLayers;
for (var i = 0; i < myLayers.length; i++){
var myContents = myLayers[i].property("ADBE Root Vectors Group").property("ADBE Vector Group").property("ADBE Vectors Group").property("ADBE Vector Graphic - Stroke").property("ADBE Vector Stroke Line Cap").setValue(2);
}
app.endUndoGroup();

And this is what i’m doing trying to work through all the properties (i want it to work in any scenario):

var project = app.project;
var comp = project.activeItem;
app.beginUndoGroup("Process");
var myLayers = comp.selectedLayers;
for (var i = 0; i < myLayers.length; i++){
var myContents = myLayers[i].property("ADBE Root Vectors Group");
for (var j = 1; j <= myContents.numProperties; j++){
myContents.property(j).property("ADBE Vector Group").property("ADBE Vectors Group").property("ADBE Vector Graphic - Stroke").property("ADBE Vector Stroke Line Cap").setValue(2);
}
}
app.endUndoGroup();

Hi Vincenzo,

since you can’t be sure of the exact “path” to the Line Cap property (it can be embedded into a shapegroup, there could be multiple paths/shapes/rectangels etc, each with multiple strokes…) I think you need to go through each property recursively and if it’s the right one, apply the value.

Something like this:

var project = app.project;
var comp = project.activeItem;
app.beginUndoGroup("Process");
var myLayers = comp.selectedLayers;
for (var i = 0; i < myLayers.length; i++){
    tryLineCap(myLayers[i].property("ADBE Root Vectors Group"))
}
function tryLineCap(prop) {
    for (var j = 1; j <= prop.numProperties; j++){
        var subProp = prop.property(j);
        if (subProp.numProperties) {
            tryLineCap(subProp)
        } else {
            if (subProp.matchName == "ADBE Vector Stroke Line Cap") {
                subProp.setValue(2);
            }
        }
    }
}
app.endUndoGroup();
