— it's an absolute lifesaver when you need to move to a save slots system. All of the webstorage references in Airscape are function calls that pulls the data from the current save slot.
I usually just have a global variable called something similar to "ProfileName" or "SaveSlot", and then if I need a variable (like the HP) from that profile slot I'd just get the value from the key called: ProfileName & "health"
So I still don't understand the purpose of functions, thanks for answering though!
