Why do i get a nil in return if the variable is global?

Asked by

I get an error about lol being nil, at line "print(lol)", i think im not understanding the flow of code that includes the player added and removed functions. Also the script can't be local.

Players = game:GetService("Players")

game.Players.PlayerAdded:connect(function(player)

lol = 3

end)

game.Players.PlayerRemoving:connect(function(player)

print(lol)

end)

It's null because its only global in your scope { }. If you want it to be global throughout your script then place it outside of that function. Impacthills 223 — 7y

it's nullified because you already ended the script right there when you put an "end)" Astralyst 389 — 7y

I think this will help your problem:

local lol = "EmptyString"
Players = game:GetService("Players") --This could also be 'game.Players'

game.Players.PlayerAdded:connect(function(player)
    lol = "3"
end)

game.Players.PlayerRemoving:connect(function(player)
    print(lol)
end)

Perhaps even thou you didn't make the 'lol' variable local in the PlayerAdded function, it probably still made usable only within that function.

The only difference between local functions/variables and global functions/variables is that a global functions/variable can be referenced before it is assigned, so this is correct:

local lol = "lol"
print(lol)

This is correct too:

print(lol)
lol = "lol"

but this is not:

print(lol)
local lol = "lol"

So yeah, hope this fixes your problem :D
