Question
I changed the parent of the BoxMenu now my code aint working, when I click Options in the GameMenu it shows me the error Invalid access to property or key ‘item_selected’ on a base object of type ‘null instance’. "see screenshot for more details"
It worked before (not perfect), I tried the name it correct in the :
