  Set position to composition

  Posted by Victor Ribbs on June 19, 2020 at 8:30 am

  hello,
  I dynamically add compositions (as_msg) in a basic composition (as_comp)
  var comme_comp = app.project.item (1);
  var tels_msg = app.project.item (2);
  I tried to assign positions to each tels_msg but without success. I manage to move the layers contained in tels_msg
  thank you

  // \COMP BASE
var tels_comp = app.project.item(1);
// \COMP MESSAGE
var tels_msg = app.project.item(2);
...
function addMsgs()
{
for ( i = 0; i < tels_data.length; i++){
var _layerCollection = tels_comp.layers;
var msg_instance = tels_msg.duplicate();
//var msg_instance.name = "MSG_INSTANCE_"+i;
var msg_layerCollection = msg_instance.layers;

  addAvatar(i, msg_layerCollection.byName("AVATAR_SHAPE"));
  addInitialName(i, msg_layerCollection.byName("AVATAR_INITIAL"));
  addName(i, msg_layerCollection.byName("SEND_BY"));

  _layerCollection.add(msg_instance);
}
}

  hello,

  I found the solution to my problem.
  the last layer added to layers is always linked in 1

  var msg_position = tels_comp.layer(1).property("ADBE Transform Group").property("ADBE Position");

  function addMsgs()
{
var nL = 1;
var _layerCollection = tels_comp.layers;

  for ( i = 0; i < tels_data.length; i++){

  var msg_instance = tels_msg.duplicate();
  msg_instance.name = "MSG_INSTANCE_"+i;
  var msg_layerCollection = msg_instance.layers;

  addAvatar(i, msg_layerCollection.byName("AVATAR_SHAPE"));
  addInitialName(i, msg_layerCollection.byName("AVATAR_INITIAL"));
  addName(i, msg_layerCollection.byName("SEND_BY"));

  _layerCollection.add(msg_instance);
  var msg_position = tels_comp.layer(1).property("ADBE Transform Group").property("ADBE Position");
  msg_position.setValue([x_pos, y_pos]);

  nL++;
y_pos += 120.0;
}
}
