more expression begging
right..
is it possible for an expression to use the name of the comp in which it resides as a variable, and then to use this variable to define which properties it references from another comp?
to give you the context:
i have made a comp – “comp A” – which has all kinds of layers with properties ultimately defined by 2 variables. “Comp A” is nested in “comp B”.
the variables are:
1: the distance from the nested layer in comp B to the camera in comp B
2: the relative rotation between the two layersthe effect being that as the camera approaches the layer, its distance and rotation is refelcted visibly by elements in the layer.
i want lots and lots of instances of this layer. since it is all done with expressions, if all instances were identical, they would mirror the first layer since the expressions are all pointing to this to calculate their values.
i wish to avoid manually adjusting all the expressions to make their calculations according to the appropriate layer.
i was wondering if i could write a universal script that would use the number of the comp (ie “comp A02”, “comp A03”) it resides in to determine which layer from the main comp (“comp B”) to access.
I hope this makes sense.
if anyone can help me out il be very grateful.

As far as I know, there’s no way for an expression to access the parent comp of the comp it resides in, except directly by name.

so is there no way to access the name of any given object and declair it as a string?

You can convert anything to a string, but it wouldn’t do you that much good. You have to use explicit calls to reference items across multiple comps and unlike with JSX scripts, expressions do not have a parent.Comp() method for checking this on their own. So that means you would still have to take care to explicitely name each item and composition for the string filtering to make sense which is no different than adjusting the expressions themselves.
