Copy selected property to a Null Layer's Position
I’m trying to write a script that will copy keyframes from a selected property to the position property of a new null. For example, in the image below I want to select Point1 keyframes from the Lockdown effect and have them copied to a null layer’s position with the name “Point1”.
I am having a tough time getting the script to paste just the keyframes to the position value of the null instead of pasting the entire Lockdown effect.
I have disabled the naming part of the script…can’t get it to work.
app.beginUndoGroup("Copy to Null");
{
app.executeCommand(19); //copy
var controller = app.project.activeItem.layers.addNull(); //Create null
//myProp = app.project.item[0].layer[0].selectedProperties.name; //Selected property name
controller.name = "myProp"; //Name null
controller.enabled = true;
nullLayer.property("position");
app.executeCommand(20); //paste
}
app.endUndoGroup();

Hello, maybe something like this:
app.beginUndoGroup('Copy to Null');
app.executeCommand(19);
var controller = app.project.activeItem.layers.addNull();
controller.name = 'myProp';
controller.enabled = true;
controller.property('position').selected = true;
app.executeCommand(20);
app.endUndoGroup();

Yes! That’s working. Thank you. Is there any way to name the null layer based on the selected property and also have it create a null for each point selected so that there is a null titled “Point1”, “Point2” and so on depending on what’s selected?

It should work.
function createNulls() {
var sLayers = thisComp.selectedLayers;
if (!sLayers.length) {
alert('Please, select a layer');
return false;
}
var sProperties = thisComp.selectedLayers[0].selectedProperties;
if (!sProperties.length || sProperties.length < 2) {
alert('Please, select at least 1 property');
return false
}
app.beginUndoGroup('Copy to Null');
for (var i = 0; i < sProperties.length; i++) {
var sProperty = sProperties[i];
if (sProperty.numProperties == 2) {
var myNull = thisComp.layers.addNull();
myNull.name = sProperty.name;
myNull.transform.position.expression = 'thisComp.layer("' + sLayers[0].name + '").effect("' + sProperty.name + '")(1)';
myNull.transform.position.selected = true;
// OPTIONAL
// app.executeCommand(2639); // Convert Expression to Keyframes
// myNull.transform.position.expression = ''; // Remove the Expression
}
}
app.endUndoGroup();
}
var thisComp = app.project.activeItem;
createNulls();

Thank you! I gave it a go but it’s not working. If I select a layer and the position property I get a message stating that I need to select at least one property and when I select the keyframes from the Lockdown plugin nothing happens.

For Lockdown use this code:
function createNulls() {
var sLayers = thisComp.selectedLayers;
if (!sLayers.length) {
alert('Please, select a layer');
return false;
}
var sProperties = thisComp.selectedLayers[0].selectedProperties;
if (!sProperties.length || sProperties.length < 2) {
alert('Please, select at least 1 property');
return false
}
app.beginUndoGroup('Copy to Null');
for (var i = 0; i < sProperties.length; i++) {
var sProperty = sProperties[i];
if (sProperty.name.match(/Point[1-4]/)) {
var myNull = thisComp.layers.addNull();
myNull.name = sProperty.name;
myNull.transform.position.expression = 'thisComp.layer("' + sLayers[0].name + '").effect("Lockdown")("' + sProperty.name + '")';
// OPTIONAL
// myNull.transform.position.selected = true;
// app.executeCommand(2639); // Convert Expression to Keyframes
// myNull.transform.position.expression = ''; // Remove the Expression
}
}
app.endUndoGroup();
}
var thisComp = app.project.activeItem;
createNulls();

Perfect. Thank you for your help. I really appreciate it.

Fabrice Leconte,
Are you available for hire? I have some ideas for some scripts that I would like to hire you to build if you’re interested.
