Help with making a 'global function'

[ib_ppa (boppa)]

I want to make a series of functions that can be applied to any object. For example:

local object = Instance.new("Part")

local funcs = {}
function funcs:test() --(I want to be able to use self)
    print(self.Name)
end

object:test()

I tried this with a module and a normal script, but both threw this error:

What’s the correct method to achieve this?

You will want to wrap it.

local function wrap(instance)
    return setmetatable({ this = instance }, { __index = instance })
end

local wrapped = wrap(Instance.new("Part"))

function wrapped:test()
    print(self.Name)
end

wrapped:test()

A global function would probably need to be stored in a module script.

local funcs = {}
local object = Instance.new(“Part”,workspace)
function funcs:test() --(I want to be able to use self)
    print(self.Name)
end
return funcs

And then require it. That should work.

I tried that exact function and it threw the same error

Wrapping with metatables, or "How to alter the functionality of Roblox objects without touching them"

This is a tutoral on using metatables to create wrappers around Roblox’s locked objects, such as Instances and special data types. This gives you the freedom to change or add new functionality to the existing API. The following guide assumes you’re comfortable with Lua, particularly with metatables, and are familiar with the direction Roblox’s object-based scripting tends to go. I’ll preface this with a disclaimer: This isn’t a very good idea. Using Roblox’s API the way it was intended helps wi…

Yeah, you and @sjr04 got it. I’ve decided against using it though as it really has no functional benefit in rbxlua. It’s fun to play with but decreases efficiency, really just syntactic sugar.
