Hey scripters! Just asking a question here!

What does a return do in RLua and when would I need to use it? Can I attach arguments to it?

What is the point of returning?

A return statement ends a function’s execution and ”return” control to the main program.

If you put a value after return, the value will be the output of the function.

Returns are mainly used for functions, lets say you send a request, the function does a operation and returns a new value.

local function ChangeNumber(Number)
   Number = Number*2
   return Number, "The New Number"
end

local NewNumber,stringzz = ChangeNumber(12)
print(NewNumber) -- 24
print(stringzz)--"The New Number"

Where you would may use Returns:
