  Match Properties Selection

  Posted by Rodrigo Kermessi on December 28, 2022 at 1:42 pm

  Hi friends! Hope you´re all doing good!

  I´m trying to create a script that you can select layers and some properties and match the selection of the properties. I mean, all selected layers would have the same properties selected.

  I´m almost there, it works great with: position, rotation, scale, opacity. But, doesn´t work with any other property.

  Here is the script so far:

  <b style="">var myComp = app.project.activeItem;
  //selected properties
  var myProps = myComp.selectedProperties;
  for (var p = 0; p < myProps.length; p++){
  //selected layers
  var myLayers = myComp.selectedLayers;
  for (var l = 0; l < myLayers.length; l++){
  // select matched properties for selected layers
  myLayers[l].property(myProps[p].name).selected = true
  <b style="">}};

  Please, ignore both <b style=””> not sure how it appeared there.
  The right code (so far) would be:

  var myComp = app.project.activeItem;
  \\selected properties
  var myProps = myComp.selectedProperties;
  for (var p = 0; p < myProps.length; p++){
  \\selected layers
  var myLayers = myComp.selectedLayers;
  for (var l = 0; l < myLayers.length; l++){
  \\select matched properties for selected layers
  myLayers[l].property(myProps[p].name).selected = true

  }};

  To do that, I think you have to build the property spec path on the fly, like this:

  var myComp = app.project.activeItem;
  var myProps = myComp.selectedProperties;
  for (var p = 0; p < myProps.length; p++){
  	var myLayers = myComp.selectedLayers;
  	for (var l = 0; l < myLayers.length; l++){
  		var myProp = myProps[p];
  		var myPropString = "";
  		while (myProp.parentProperty !== null){
  			var name = "\"" + myProp.name + "\"";
  			myPropString = ".property" + "(" + name + ")" + myPropString;
  			myProp = myProp.parentProperty;
  		}
  		if (myPropString != ""){
  			eval("var myActualProp = myComp.layer('"  + myLayers[l].name  + "')" + myPropString + ";");
  			myActualProp.selected = true;
  		}
  	}
  };

  Hi Dan, thank you so much, it worked perfectly.

  I´m a big fan of yours! It´s impressive that 99% of the thing that I had issues, like forever, about expressions and scripts for AE, was solved by you in some forum over the internet or even learning in the classic MotionScript.com. Legend!

  PS: The first plugins I ever bought was TypeMonkey and MotionMonkey. 🙂

  Best Wishes!
