Return variable?

[xnSly (Sly)]

I was working on a script for a commission and I saw the previous scripter wrote what looks like a function but it’s formatted a little different from what I’m used to, an example of what it looked like is:

local variable; do
    -- function stuff
end

Is this like a regular function but sets the return value to a variable or something? I’m not sure if this is even considered a function.

It doesn’t do much it’s just a line break creating variable called variable.

Then do end

What is "do end" used for?

Literally speaking, it does and then ends. Code inside of a do just executes in a new local scope. Basically, it allows you to separate the p variables in that example. So the p in the first do won’t accidentally be reused when it’s not needed in any other scope. The post that code came from is using it to show how garbage collection works. do local x = 5 end print(x) Essentially, x won’t be available outside the do, so this will print nil.

[Forummer]

local Game = game
local RunService = Game:GetService("RunService")

local function OnStep(Connection)
	Connection:Disconnect()
end

local Connection do
	Connection = RunService.Stepped:Connect(function() OnStep(Connection) end)
end

That idiom is typically employed in order for a variable to be included in a chunk’s scope.
