Returning is a way to get info out of a function. Let me give you an example:
1 | function Add(a,b) |
2 | return a+b |
3 | end |
This will take two numbers and add them together, then return the result.
So if we do this:
1 | Add(1,3) |
Lua will read it as '4'
Here's a full example:
1 | function Add(a,b) |
2 | return a+b |
3 | end |
4 |
5 | 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.

"return" replaces where the function was called with whatever you put after the return statement. GoldenPhysics 474 — 10y
