local

What is the real difference between the following two things.

This:

  
helloText = "Hello World" 
  

and

  
local helloText = "Hello World" 
  

Yes I am talking about "local" - What is it exactly? How does it change when you type/dont type it? Please help

For example you can create global variables in 1 lua file and use it within the resource folder, while local variables are more faster then global ones and are most common used.

You can read more: http://lua-users.org/wiki/ScopeTutorial

Also if I'm not wrong you can use local variables within the whole script or inside the function.Ones inside function are used only in that function while the ones that aren't in function can be used within the whole code.

Aha, so is this also why I see

  
local function jaja() 
end 
  

sometimes?

So this function is only accessible and visible to the file ?

So I can keep one function called changeText in multiple files (different) and they will only run the one in the file ?

THANKS

You can download Lua 5.1 and practice with Lua command line (similiar to command prompt) to easily test stuff.
