Iterate script for all selected layers?

[Kevin Snyder]

I have this script working for my selected properties on a single layer. However, I’m trying to get it to work on multiple layers simultaneously, but I’m not able to get it to work. I think the problem has to do with line 3, but I don’t know how to tackle it. Thanks.

function myBridgeController(myBridge){
    var myComp = app.project.activeItem;
    var myLayers = myComp.selectedLayers[0];
    var myProps = myLayers.selectedProperties;
    var myControl = app.project.activeItem.layer(myBridge);
if (!myControl){
    var controller = app.project.activeItem.layers.addNull();
    controller.name = myBridge;
    controller.enabled = false;
}
for (var i = 0; i < myProps.length; i++){
    var myEffect = myComp.layer(myBridge).Effects.addProperty("ADBE Checkbox Control");
    myEffect.name = myBridge + " " + myLayers.name + " " + myProps[i].name;
    var myExpr = 'thisComp.layer("' + myBridge + '").effect("' + myEffect.name + '")("Checkbox");';
    myNewProp = myComp.layer(myBridge).property("Effects").property(myEffect.name).property("Checkbox");
    myNewProp.addToMotionGraphicsTemplateAs(myComp, myEffect.name); 
    myProps[i].selected = true;
    myProps[i].expression = myExpr;
 }
}

I’m not sure, but if you’re planning on looping this through multiple layers, I think you first need to save the state of which layers and properties are currently selected, because the actions of your function will change that. So you’d need to restore those selections each time through the loop, or change the function to expect layer names and property path specs. It could be tricky, and a little messy.

Thanks, Dan. I appreciate the feedback. I thought that I may have been overlooking something obvious.
