How do you access functions in module scripts?
Okay so I wan't to use module scripts as I can keep my functions manageable. I have two questions,
First Question : Can I use multiple functions in a module script? Second Question : How can I access Functions Inside Module Scripts?
I don't know if im supposed to use _M. before each function or if roblox makes it global for you. I also saw some people doing this:
local myModule = require(game.Workspace.MyModule) myModule.MyFunction(mainArg, secondArg) -- My Function is inside myModule.
So will this work? And do I need to type _M. Before every module function, and can I change arguments and It'll still work inside the module?

Interestingly someone just asked me this on a twitch stream. I have a funny feeling this isn't coincidence :p
There are two things you need for a module to work.
A ModuleScript somewhere in the game
A script that Requires the module.
The ModuleScript:
local Module = {}
Module.SomeFunction = function(parameters)
-- code
end
Module.AnotherFunction = function(moreparameters)
-- code
end
return Module
In a Server Script...
local module = require(game.ServerScriptService.Module) module.SomeFunction(parametertopass) end
A more practical example:
local AddModule = {}
AddModule.Add = function(a,b)
return a+b
end
return AddModule
Server Script:
local add = require(game.ServerScriptService.AddModule) print(add.Add(2,3)) -- will print 5.
Note that modules will cache, so print(add.Add(2,3)) will print 5, and all subsequent calls will also return 5. (print(add.Add(10000,10000) will print 5 etc etc)
I hope my explanation helped. The wiki page is also very useful
