  Setting Layer Postion

  Posted by Stephen Botting on September 21, 2010 at 10:42 pm

  I am working a project with nearly 400 layers, and have been using Expressions to place the layers in time(time remapping) and position.

  But have started playing in extendscript to write a script that can place the layers in time and position before rendering, to save evaluating the expressions every frame.

  I have successfully got my layers to start at the correct time, but when I try to set their position they don’t move and the script reports no errors, any ideas how this is done.

  Thanks,
  Stephen

  var selectedLayers = app.project.activeItem.selectedLayers;

  for (i = 0; i < selectedLayers.count-1; i++) {
  selectedLayers[i].position = [100,100]; //just an example position

  //also tried
selectedLayers[i]("position") = [100,100];
selectedLayers[i].position.value = [100,100]; //returns value is readonly
selectedLayers[i].postion.setValue = [100,100];
}

  this

  myLayer.property(“Position”).setValue(theVal1);

  or this

  theLayer.position.setValue([1632,1224,0]);

  not this.
  selectedLayers[i].postion.setValue = [100,100];

  Thanks for the reply, I’m assuming from this that I need to include the Z position even when the layer is 2D.

  Worked great once I looked at your code properly.

  Cheers,
  Stephen
