How do I wrap instances to create custom methods to that instance?

Just like the title says, how do I wrap instances to create custom methods to that instance?

Here’s an example of what I’m trying to do:

local wrappedPart = wrap(workspace.myCoolPart)

wrappedPart:WaitForChildOfClass("Script")

It would be great if you could help!

I’ve tried learning it myself but haven’t actually tried it so I’ll link the post that I learned from:

Wrapping objects and adding functionalities to them

Two articles have already covered this topic (link and link), and they’re both good! But I wanted to approach this idea in my own way. A way that would feel nicer for beginners, especially those that have learned about metatables, and really couldn’t get their heads around how they’d use them. Which is why might need a good bit of knowledge about metatables and various of bits of object-oriented programming. Also, I’m gonna be digging deep to talk about more stuff. First of all, what’s wrappin…

it’s just a bunch of metatable magic really

Spoofing a game service

Although a little inconvenient, you can try something like this: local function wrap(self, key: string) -- Wraps any methods in an extra function to fix the the "expect ':', not '.'" error local service = getmetatable(self).__service local success, output = pcall(function() return service[key] end) if not success then error(output) -- Key doesn't exist at all end if type(output) == "function" then return function(_, ...) -- Calls the method correctly return ou…

In addition to the link posted prior to this, I also did something like this a few years ago

I want to make a module for it and make it supportive for all instances

[LobsterGames99]

You could create a new wrapped instance class like this:

local WrappedInstance = {}
WrappedInstance.__index = WrappedInstance

function WrappedInstance.new(instance: Instance)
	local self = setmetatable({}, WrappedInstance)
	self.Instance = instance
	return self
end

function WrappedInstance:DoSomething()
	print("Doing something with " .. self.Instance.Name)
end

-- You can add any function you want

return WrappedInstance

And you can use it like this:

local WrappedInstance = require(Path.To.WrappedInstance)

local myWrappedPart = WrappedInstance.new(Instance.new("Part")) -- you can wrap any instance you want
myWrappedPart:DoSomething()

myWrappedPart.Instance:FindFirstChildOfClass("Script") -- can still access instance properties!
