Using "data tables"

(Contains content from multiple discussions) Think of element.data and element:getAllData.

• variables return a referenced table
• function returns a copy

element.data.moo = "foo" -- works!
element:getAllData().moo = "foo" -- doesn't work!

local elementData = element.data
elementData.moo = "foo2" -- works!

OOP Metatable Restructure

(Contains content from multiple discussions)

• "right now set and get functions for variables are hidden, people can't easily manipulate them", "i wanna move them to the class table".
• For example:

Element.health = { __set = setElementHealth, __get = getElementHealth }
-- lil_Toady originally suggested "set" and "get", but this could cause conflicts
-- if users assigned variables to "set" and "get" for purposes other than this

• This makes it "a bit more transparent" and will make inheritance better by applying inheritance on the class table directly
  • > this will be faster and much easier for users to implement their own classes

Zombie = {...}
setmetatable ( Zombie, { __index = Ped } )
