how would i return a value inside a connect function that i would like to disconnect at the same time for example

local added

added = game.Players.PlayerAdded:Connect(function(player)
    
    added:Disconnect()
    return player
    
end)

print(added)

this just prints prints connection but i want it to print the value i am returning instead(player) ive tried two variables but the second one just prints nil instead

How would I return a metatable from a :connect function?

Need to assign the player to an upvalue. Return in a function given to a Connect method means that the value would be returned to the Connect method call and the engine doesn’t do anything with any values returned to Connect.

local added, player

added = Thing:Connect(function (foobar)
    player = foobar
    added:Disconnect()
end)

I mean though, unless you’re doing anything else in this function, you just check whatever gets passed to PlayerAdded and then disconnect, so why not just use wait?

local player = Players.PlayerAdded:Wait()

Functionally the same and doesn’t require you to manage a connection. When PlayerAdded fires, this will return whatever PlayerAdded fired with.

I’m not sure how heavy you lean towards functional programming but upvalues/non-locals can be avoided.

Providing everything is contained within functions you can simply pass that player instance from its “.PlayerAdded” event to any function which requires it.

You could use “Once” too so you won’t have to dissconnect the function, but the current solution is shorter, which means better, of course.
