  Problem with changing a layers position in a script

  Posted by Coby Gross on May 22, 2013 at 5:47 am

  So I have a script that needs to change the position of a layer but I keep getting this error: invalid numeric result(divide by zero?)

  here is the line:
  myComp.layer(2).transform.position + [5,2]

  Any ideas as to why I would get this?
  Here is my While loop, also, the layer is a precomp if that makes a difference(I didnt think it would though)

  
var myComp;
//Read lins of text. Create a new comp and text layer for each line
var text;

  while(!myFile.eof)
  {
  text = myFile.readln();
  if(text == "") text = "r";

  myComp = app.project.items.addComp(text,compW,compH,1,compL,compRate);

  //////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////Set the text layer
  var tl = myComp.layers.addText(text);
  var tltxt = tl.property("ADBE Text Properties").property("ADBE Text Document");
  var txt = tltxt.value;
  txt.font = "Verdana";
  tltxt.setValue(txt);
  ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
  var precomp = myComp.layers;

  precomp.precompose([1],text + "precomp");
  myComp.layer(1).duplicate();
  ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////Add Fill Effect
  layerProperties = myComp.layer(2);
  layerProperties.Effects.addProperty("Fill");
  layerProperties.Effects.property("Fill").property("Color").setValue([0,0,0]);

  ////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////Add the offset

  //layerProperties.transform.position + [5,2];
  myComp.layer(1).transform.position + [5,2];

  }

  If you’re trying to move the position of layer(1), I think you would need something more like this:

  var myVal = myComp.layer(1).property(“Position”).value;
  myComp.layer(1).property(“Position”).setValue(myVal+ [5,2]);

  Yes, that did it. Thank you so much. Nearly every example I saw online had it something like myComp.layer(1).transform.position + [5,2]; So frustrating ha.

  Thank you again, you rock.

  Thanks to you and Dan, I found that this works as well:

  myComp.layer(1).transform.position.setValue([5,2]);

  Looks a bit less complicated to me.

  Best,
  Jan

  myComp.layer(1).transform.position.setValue([5,2]);
