  Accesing 1st and 2nd keyframe of a mask from selected layer

  Posted by Tom Pinnes on December 30, 2020 at 4:14 pm

  Hello everyone i just started scripting with ExtendScript ToolKit and i’m in need of some direction.

  I’m trying to write a script that collects the vertices of a mask from the 1st keyframe and 2nd keyframe.

  *Assume the layer is selected and a layer holds at least 2 keyframes and is a rectangle.

  Here is my code so far, it’s lacking the most important part and this is where i need your help 🙂

   

  var project = app.project

  var currentComp = project.activeItem

  var selectedLayers = currentComp.selectedLayers

  var myLayer = selectedLayers[0]

  var layerIn = myLayer.inPoint

  var layerOut = myLayer.outPoint

  var selectedMask = myLayer.Masks(“Mask”)

  var newMaskShape = selectedMask.property(“maskShape”)

  var newShape = newMaskShape.value

  var shapeVert = newShape.vertices

  /// Find a way to select 2nd keyframe vertices

   

   

  Thanks in advance !

  Don’t forget semi-colons to end your statements.

  I modified your code a bit. Here’s how I’d get those vertices:

  var project = app.project;
  var currentComp = project.activeItem;
  var selectedLayers = currentComp.selectedLayers;
  var myLayer = selectedLayers[0];
  var layerIn = myLayer.inPoint;
  var layerOut = myLayer.outPoint;
  var maskPathProp = myLayer.mask("Mask 1").maskPath;
  var vertices1 = maskPathProp.keyValue(1).vertices;
  var vertices2 = maskPathProp.keyValue(2).vertices;
  alert(vertices1);
  alert(vertices2);

  Hey Walter thanks for putting the time to help me!

  Yeah i forgot about the semi-colons.. Also this is more elegant than my code, i’m going to use it.

  Thanks
