Using 1.x style of programming in pre-1.x servers

[Codex NG]

Although incomplete at the moment, i thought this would be a nice library to allow people developing
pre-1.x servers an opportunity to see that they too can write out their scripts in 1.x style of programming

Inspiration from this thread
https://otland.net/threads/about-metatables.240349/
Using @Non Sequitur, metatable example

I haven't quite placed all the metatables together.. eventually i will get around to it

All these functions are from an 8.6 server.

You are using the same constructor and table for Player, Npc, Monster and Creature.

-- inherit all the metamethods of Creature
Player, Npc, Monster = Creature, Creature, Creature

No, this doesn't copy the table Creature to Player, Npc and Monster.

That could be a solution:

function newClass(constructor, parent)
    local methods = { }
    if parent then
        methods.__parent = parent
    end
    local MT = {__index = function(a, b) if methods[b] then return methods[b] elseif methods.__parent and methods.__parent[b] then return methods.__parent[b] end end}

    local call = function(self, ...)
        local obj = constructor(...)
        if not obj then
            return nil
        end

        return setmetatable(obj, MT)
    end

    return setmetatable(methods, {__call = call})
end

Creature = newClass(function(id)
    return {id = id}
end)

Player = newClass(function(id, guild)
    return {id = id, guild = guild}
end, Creature)

function Creature:getId()
    return self.id
end

function Player:getGuild()
    return self.guild
end


local player = Player(100, 5)
local creature = Creature(20)

print(player:getGuild(), player:getId())
print(creature:getGuild()) --  attempt to call method 'getGuild' (a nil value)

Like this you can define Player and "inherit" all methods from Creature.

It is incomplete yes & thanks for the clarification.
