RE: Menus and submenus (WAS: Forward Declaration)

["Kevin Baca" <lualist@...>]

There are A LOT of things wrong here.  It's clear what you're trying to
do, but you're lacking some understanding of basic lua syntax.  Take
baby steps.

Here's a start:

Menu = {}

function Menu:new()
    local menu = setmetatable( {}, { __index = Menu } )
    menu.items = {}
    return menu
end

function Menu:add(name, id)
    local item = { name = name, id = id }
    table.insert( self.items, item )
    return self
end

mainMenu = Menu:new()
    :add("Item0", 0)
    :add("Item1", 1)

print( mainMenu.items[ 1 ].name )
print( mainMenu.items[ 1 ].id )
