I'm doing something similar. Here's my current setup. I'm using 5.0beta.
areas = {}
function nominate(t) -- takes a numeric array,
-- and makes it an associative table
-- through each member's "name" member
table.foreachi(t, function(i, v)
t[v.name] = v
t[i] = nil
end)
end
function area(area)
nominate(area.rooms)
if not area.name then
error "Need to name this area"
end
areas[area.name] = area
end
function room(room)
if not room or not room.name then
error "Need to name this room"
end
return room
end
area {
name = "house"
rooms = {
room {
name = "bedroom"
desc = "Joe's Bedroom"
foo = function()
print("Hello!")
end
},
room {
name = "bathroom"
desc = "Wendy's bathroom"
}
}
}
print(areas["house"].rooms["bedroom"].desc)
print(areas["house"].rooms["bathroom"].desc)
areas["house"].rooms["bedroom"].foo()
Hope this helps.
