  “Scripting” linking propertyIndex to an Array Index

  Posted by Cyril Drouin on March 28, 2018 at 9:54 am

  Hi everyone,

  I’m trying to push my knownledge on scripting more than i can do.
  So I am writing a script for morphing one text layer to another text layer (with the same letters but with different size like regular to bold) and i have an issue.

  I want to copy key frame at time 2 of my first Shape to the other for morphing between each keys.
  I push my keys of the first shape in an Array and for the second shape I have a setValueAtTime
  myprop2.setValueAtTime(2, keysFirstshape[0]);
  It’s working but just with one key shape i imagine i have to feet my number of second keys shape and keys in my array ? but i don’t know how to do that, i spent my last day trying.
  May be it’s not the good solution

  All the code:
  //Selects txt Layers A & B
var myLayer = app.project.activeItem.selectedLayers;
var myLayerIndex = new Array();
var keysFirstshape = new Array();
//Stores selected Layers in Array
for (i = 0; i < myLayer.length; i++) {
myLayerIndex.push(myLayer[i].index)
}

  /**********************************************************************************************
  Selects Layers in comp and create shape from txt
  ***********************************************************************************************/
  var selLayers = app.project.activeItem.layers;
  //Loops through deselecting them
  for (var j = 1; j <= selLayers.length; j++) {
  selLayers[j].selected = false;
  }
  //Selects targer layer from stored selection
  var targetLayer = app.project.activeItem.layer(myLayerIndex[1]);
  targetLayer.selected = true;

  //txt to shape
  app.executeCommand(3781);

  /**********************************************************************************************
  add key to all shape and copy the values
  ***********************************************************************************************/
  var myLayers = app.project.activeItem.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");
  propertySearch(myContents);
  }
  }

  function propertySearch(a) {
  for (var j = 1; j <= a.numProperties; j++) {
  for (var k = 1; k <= a.property(j).numProperties; k++) {
  if (a.property(j).property(k) == a.property(j).property("ADBE Vector Shape")) {

  a.property(j).property(k).addKey(0); // add key
  var myPath = a.property(j).property(k);
  myPathNumb = a.property(j).property(k).numProperties;
  myPath.setSelectedAtKey = true;
  keysFirstshape.push(myPath.keyValue(1));

  }
  propertySearch(a.property(j).property(k));

  }
  }
  }

  /**********************************************************************************************
  deselected layers and select the other txt layer for transform to shape
  ***********************************************************************************************/

  var selLayers = app.project.activeItem.layers;
  //Loops through deselecting them
  for (var f = 1; f <= selLayers.length; f++) {
  selLayers[f].selected = false;
  }

  var targetLayer2 = app.project.activeItem.layer(myLayerIndex[1]);

  targetLayer2.selected = true;

  //Applies command to selected layer
  app.executeCommand(3781);

  /**********************************************************************************************
  add key value fro the second shape and paste key values of the frist shape
  ***********************************************************************************************/

  var myLayersb = app.project.activeItem.selectedLayers;
  var myLayerb2;
  for (var g = 0; g < myLayersb.length; g++){
  myLayerb2 = myLayersb[g];
  if (myLayerb2 instanceof ShapeLayer){
  var myContentsb = myLayerb2.property("ADBE Root Vectors Group");
  propertySearchb(myContentsb);
  }
  }

  function propertySearchb(t) {
  for (var l = 1; l <= t.numProperties; l++) {
  for (var h = 1; h <= t.property(l).numProperties; h++) {
  if (t.property(l).property(h) == t.property(l).property("ADBE Vector Shape")) {

  var myprop2 = t.property(l).property(h);
  t.property(l).property(h).addKey(0);
  myprop2.setValueAtTime(2, keysFirstshape[0]);

  }

  propertySearchb(t.property(l).property(h));

  }
  }
  }

  Thank you
