get position of a precomped object
Hello,
I’ve got this crane made in illustrator..
It’s pretty big, scaled down to round 20% in a full HD comp (main comp). All the parts of the crane are parented to one and another controlable from the main comp with sliders.
Also everything in the main comp is parented to a null so I can scale the scene up and down.
I would like to have a null follow the position in main comp.
I tried with toWorld and got the position quite offset. This in turn I tried to solv by subtracting ther crane’s position in the maincomp.
BUT when scaling it all went a bit wrong.Is there a simple solution for getting the hooks position in the main comp or do I have to subtract with the cranes position and multiply with the scale etc?
Thanks!

The trick is to transform the hook’s position into its own comp’s world space with toWorld() and then transform that result from the inner comp’s layer space (as a layer in the main comp) to the main comp’s world space. It will look something like this, depending on how many levels of nested comps you have:
L1 = comp(“Crane”).layer(“Hook”);
P = L1.toWorld(L1.anchorPoint);
L2 = thisComp.layer(“Crane”);
L2.toWorld(P);You could probably also just parent a null to the appropriate spot within the main comp and use thisComp.layer(“Null 1”).toWorld([0,0,0]);
