Local Functions

[KTBM]

Can someone please explain what the difference is between a local function
[lua]local function doSomething()[/lua]
and a global function
[lua]function doSomething()[/lua]
And when it is best to use them

Same as how 'local' normally works - It means the function only 'exists' and therefore exectutable from that chunk

And by the chunk you mean the file?

[NiandraLades]

Indeed - I gotta be honest, I've never actually used local functions but I assume it's for making sure it doesn't conflict with any others of the same name

[lua]-- main.lua
include( "file1.lua" )
include( "file2.lua" )

-- file1.lua
local var = "Hello"
print( var ) -- > "Hello"

local function LocalFunction()
local var2 = "Hola"
print( var ) -- > "Hello"
print( var2 ) -- > "Hola"
end

LocalFunction()
print( var2 ) -- > nil

function GlobalFunction()
print( "Bonjour" )
end

globalvar = "Ni hao"
print( globalvar ) -- > "Ni hao"

GlobalFunction() -- > "Bonjour"

-- file2.lua
print( var ) -- > nil
print( globalvar ) -- > "Ni hao"

GlobalFunction() -- > "Bonjour"
LocalFunction() -- error: attempt to call nil value[/lua]

You should only use locals unless you have a reason to do otherwise - anything global can be accessed by [i]every[/i] other script on the server in the same realm.

It's just used for functions that you need to use with recursion/stacking or just functions you don't want being used outside of the file.
