Calling functions that are not defined yet

1. What do you want to achieve?
Basically, I want to call mapChangeFunc() in the intermissionFunc(), but I also want to call the intermissionFunc() in the mapChangeFunc().

2. What is the issue?
The problem is, one of the functions will not yet be defined when the other tries to calls it. For example:

local function mapChangeFunc()
     print("Hello!")
     wait(1)
     intermissionFunc() -- The issue, as "intermissionFunc()" is not yet defined.
end

local function intermissionFunc()
     print("Hello!")
     wait(1)
     mapChangeFunc()
end

3. What solutions have you tried so far?
So far, I have tried calling the intermissionFunc() in another function after intermissionFunc() is defined, and then calling that function in mapChangeFunc(), but then that function hasn’t been yet defined for mapChangeFunc(). For example:

local function mapChangeFunc()
     print("Hello!")
     wait(1)
     test() -- The issue, as "test()" is not yet defined again.
end

local function intermissionFunc()
     print("Hello!")
     wait(1)
     mapChangeFunc()
end

local function test()
     intermissionFunc()
end

Thanks in advance!

Well one thing wrong with your example is that it’s recursive. In this case I would just get rid of “local”. Doing this would allow you to call the function in the script wherever you want as long as its been declared before you call the first function that calls everything else.

ex:

function hi()
    bb()
end

function aa()
    hi()
end

function bb()
    print('bb')
end

aa() -- prints 'bb'

Thank you, that was it! lol ----

Use a table:

local RoundSystem = {}

function RoundSystem:Intermission()
   print('Intermission')
   self:ChangeMap()
end

function RoundSystem:ChangeMap()
   print('change map')
   self:Intermission()
end

I know this was already solved, but…

-- declare the name prematurely
local intermissionFunc

local function mapChangeFunc()
     print("Hello!")
     wait(1)
     intermissionFunc()
end

-- and define it later on
function intermissionFunc()
     print("Hello!")
     wait(1)
     mapChangeFunc()
end

This will lead to a call stack overflow however, so I would instead just run a main function that calls both in a loop.

local function mapChangeFunc()
     print("Hello!")
     wait(1)
end

-- and define it later on
local function intermissionFunc()
     print("Hello!")
     wait(1)
end

local function main()
    while true do
        intermissionFunc()
        mapChangeFunc()
    end
end

-- when you want to start the game loop,
main()
