Help With Modules?

They return stuff.

--I'm horrid at explaining stuff
--in a moduleScript--
function thing(otherThing)
    --put stuff here
end
return thing
--in a script--
thing = require(theModuleScriptObject) --will return the function thing
thing(10)

--this also helps with sending over many functons
local tab = {}

function tab.f1()
    --stuff
end

function tab.f2()
    --stuff
end

function tab.f3()
    --stuff
end
return tab
--in a script--
module = require(theModuleScriptObject)
f1 = module.f1
f2 = module.f2
f3 = module.f3

That's pretty much it. Leave a comment if this didn't answer your question.
