After Effects Scripting/ How to parent two values of the layers placed in different compositions

[Dan Ebberts]

Parenting is limited to layers in the same comp, but you could connect whichever properties you want with expressions:

comp(“other comp”).layer(“other null”).transform.position

Thanks for your respond.
Is it possible to integrate expression into script ? As I understand this expression must be written to the layer(in my example Null) property(in my case it is position). But how to integrate it into my script ?

Thanks in advance.

Like this, I guess:

myLayer.property(“Position”).expression = ‘comp(“other comp”).layer(“other null”).transform.position’;

Really?! It’s possible to define expressions this way?
Wow, never knew

[Karen Harutyunyan]

Yes that was exactly what I wanted. Thank you Dan very much. Everything works in proper way.
