How to make a game with LOVE?

It makes you a bad person.

Tables can also have functions and tables as keys. But don't do that.

Yet.

+1.
I'm using functions as keys in reverse tables (see PiL for reference) to save functions' bindings to GUI controls in text files.

[Karai17]

You monster.

[arampl]

How to do this better way then?

[kikito]

Don't listen to Karai17, he's being obtuse.

There's nothing inherently wrong in using tables or functions as keys. It's just a bit advanced, and it's preferable to learn the basics well first.

[Karai17]

Yeah, sorry, I am just being silly. As kikito said, there is nothing inherently wrong with it, but it is a very advanced activity.

[arampl]

Never mind.
Actually functions as a tables' keys can be very useful:

Code: Select all

fn1 = function(x) print(x) end
fn2 = function(x) print("bar") end
t[fn1] = "foo"
t[fn2] = "foo"
for i, v in pairs(t) do i(v) end

(from http://stackoverflow.com/questions/1456 ... table-keys)

Not too difficult to use and can be very powerful imo.

Weird.
This code runs well. (t was undeclared, so I added t = {})
Looking at the 'for' cycle. v is undeclared, what is pairs?

UPD: Nevermind, found it out. http://www.lua.org/pil/4.3.5.html
