I've recently tried to learn Lua, and I've come across the word local. What does this do to a variable?

http://wiki.roblox.com/index.php?title=Scope See if that makes any sense to you. Here's a simple example: function test () a = 5 local b = 7 print(a) print(b) end print(a) print(b) >5 >7 >5 >nil

A local variable is a variable that is only accessible in it's nested location. Example: if (condition) then local _x = 5; -- _x can only be accessed in this if statement for i = _x, 0, -1 ## ## = i; -- It can also be accessed from things lower in the heirarchy. end end -- _x cannot be accessed here
