Any idea on how i can make a function that reads a table argument such as this
This requires OOP (object oriented programming). You can read more about it here.
I already know all of OOP, i just wanna know how i can make for example a function like this New { } instead of New()
func{...} is syntactic sugar for func({...}). In your example New{"Apple"} is identical to New({"Apple"}).
You can just define a function then call the function using the table syntax.
When i do that it errors
function printArgs(t)
-- define the function normally
print(table.unpack(t))
end
-- if the function only takes 1 argument and the argument is a table, you can call it like this:
printArgs {
"Hello World!",
"This is a vararg",
"Function called",
}
Wouldn’t you need to do
function NewInstance:Construct(t)?
No Construct is equal to self aka Construct.new() in OOP and Construct is a function

Well I don’t know how to do it then, but I wrote something else as an alternative.
local construct = {}
construct.__index = construct
function construct.new()
local self = {}
setmetatable(self, construct)
function self:construct(t)
print(unpack(t))
end
return self
end
return construct
I wrote it in Lua, not Luau, so just change it for Luau’s syntax
Your script would need to look like:
-- from the Construct module script
local Construct = {}
Construct.__index = Construct
Construct.__call = function(self, t)
-- 'self' is the variable that points back to the table it's attached to
-- 't' would be the table that was sent
-- for more info about 'self': https://devforum.roblox.com/t/what-is-self-and-how-can-i-use-it/368697/2
-- the code to be executed when someone does "variable {...}" goes in here, for now, this is an example code snippet
print(table.unpack(t))
end
function Construct.new()
local NewInstance = setmetatable({}, Construct)
return NewInstance
end
-- in another script
local Construct = require( --[[<< Path to the module >>]]-- )
local New = Construct.new()
local MyPart = New {
"Hello World!" -- test argument
}
