hi, so i'm wondering if there is a way for me to refer to the node directly above the one I am on when I use centroid()???

I feel like i am almost always wanting to refer to the node directly above the one i am working on, but it feels very fiddly to have to type centroid(“../inputnodename”,D_X), etc… every time… not to mention it breaks if that node gets deleted.

I guess i could use a null node every time, but that seems a bit fiddly too.

Is there maybe a better way that I am missing?

just use input index (0,1,2,…)
so to get centroid in x of the first input it would be you can as well use opinputpath() which offers some more flexibility in some cases
so the same would be
