Function and values

[Starter1]

I got a number in one function, how to pass this number to another function(for example:

function ONE()

a=2

end

function TWO()

'here we need to pass the value a'

end

you have multiple way to acomplish this.

1. you can declare the variable outside of a function so you can access it everywhere
 

local a = 10

local function foo ()
  print (a) -- 10
end


local function bar ()
  print (a) -- 10
end

bar()

2. you can use the return statement inside a function to pass a value

local function foo ()
  local a = 10
  return a
end


local function bar ()
  local a = foo()
  print (a) -- 10
end

bar()

3.  In your code you have declared the variable a as a global since you did not use the local keyword. in this case once you run your function one time the variable a will be avalaible averywhere in the script

local function foo()
  a = 10
end
foo()

local function bar()
  print (a) -- 10
end

bar()
