  How to auto rename added Null object?

  Posted by Tomasz Tejchman on November 30, 2011 at 10:18 am

  Hi

  i Have some problem i made parser for tracking data I’m creating dynamicly null objects (i’ve found that it colud not be named by script – there is no name property if creating null 🙁 )

  so i try to loop through elements in project and renaming last added but it doesn’t works.

  for example i make composition “tracking data” and adding to it 4 null objects i want to rename them “point 1”, “point 2”, “point 3” etc. not only layers but also objects in project.

  Just name them after you create them:

  var myComp = app.project.activeItem;
  var myNull = myComp.layers.addNull(myComp.duration);
  myNull.name = “point 1”;

  Are you possibly looking at the Source Name instead of the Layer Name?

  Well, that’s certainly one way to do it. myNull.name should work though. If you toggle the timeline to display layer names instead of source names (by clicking on “Source Name”) you should see it. I apologize if you already knew this.
