How to use Returns?

Returning is a way to get info out of a function. Let me give you an example:

function Add(a,b)
    return a+b
end

This will take two numbers and add them together, then return the result.

So if we do this:

Add(1,3)

Lua will read it as '4'

Here's a full example:

function Add(a,b)
    return a+b
end

print(Add(2,5)) --this will print 7

You can also return booleans and strings. Returning is useful for functions that 'check' whether something is true, or return a string based on user input.
