I'm having a heck of a time figuring out how to get a value into an
NSTextField that is the sum or product of two or more attributes in
separate entities. For example, I have a character entity with
several ability scores as Int 16 attributes. Each of these scores can
be modified by a number of other entities. How do I make the
NSTextField display the sum of the original score, plus any modifiers?
I have a feeling I will be delving into modifying the accessor methods
of the Character entity's subclass of NSManagedObject, but i'm not
sure, and am frankly unsure how to proceed if that's the case.
Thanks so much!!
