local Blah = "IDK WHAT LOCAL DO!!"
print(Blah)
now it does something. |

local w = game.Workspace
means that in this script ONLY
the workspace can be refferred to by simply using w
a more practical, common use would be
local p = Instance.new("Part", game.Workspace) |

@pokelord910,
Are you sure, "in this script ONLY"..
Because aren't all variables in script only for that script usage :P? |

No, no.
Local is for the function, loop, conditional etc. it's in.
function local()
local t="LOLHAX"
end
print(t)
Results in an error.
Nonlocal means it can be accessed by all things in the script.
function nonlocal()
t="LOLHAX"
end
print(t)
Prints "LOLHAX". |

@ Brandon, creating a function with the name "local" has nothing to do with local and global variables.
@ dondonini, if you put "local" in front of a variable, that variable can only be accessed in the script that you assigned the variable in. If you don't use the word "local" then any script can see that variable. (I tried to word it simple as I could to help you understand) |

plus if you use local you can use the varible and change it later in the script
example
while true do
local text = ":D"
print(text)
wait(4)
local text = ":("
print(text)
end
with local you can chnage what the varible represents at any point in the script. |

No. You can do that with any variable, that's the reason they are called 'variables'.
@OP
If you use 'local' when assigning a variable, that variable will only be avaliable in the specific snipet of code where it was created at. I.E;
if true then
local Var = 'Hello'
print(Var)
end
print(Var)
>Hello
>nil |

Well I for one use local in the instance that I deal with things outside the scripts parrent that can be generalized. Like kill scripts and regen buttons. Mostly kill script then I narrow it dow by adding a couple of bools and the ine would look like
script.Parent.Touched:connect(function(part)
-- All characters have a Humanoid object
-- If the model has one, it is a character
local h = part.Parent:findFirstChild("Humanoid") -- Find Humanoids in whatever touched this

Local variables are accessed faster than normal variables, take up less space, and are generally used more often than global variables (which are the default variables). But, local variables only exist in there scope. A scope starts whenever you use the keywords do, if, and function.
local a = 5
if a == 5 then
local b = 10
print(b)
end
print(a)
print(b)
> 10
> 5
> nil
The third result is nil because the variable b's scope ended, thus making it unaccessable. The only reason it printed the first time is because you printed it inside its scope.

Local assigns the scope within the context of the given executable. |
