Hi guys,
I wonder how I can optimize this code (screenshot).
I copy a layer and want to position the copy on the exact same position without putting them in the same parent.
That's why always check for a parent and then add the parents.x,parents.y to a variable. Currently it only goes 5 times up. Can I write this more efficient and also do it till there is no parent anymore?

Thank you!

P.S.: This is for a new module that is coming soon :-)

assuming I got my coffescript right (normally I code in es6)
You just need to use recursion with an accumulator. If those terms are meaningless I can go into more detail as to what they mean.

accumulateParentOffsets = (item, accumulator) ->
if !item.parent
accumulator.x += item.parent.x
accumulator.y += item.parent.y
accumulateParentOffsets(item.parent, accumulator)

offset = accumulateParentOffsets(avatar, {x:avatar.x, y: avatar.y})

newAvatar = avatar.copy()
newAvatar.x = offset.x
newAvatar.y = offset.y
