UaLove is a library that changes the way LÖVE works to use hooks rather
than callback functions.
It is freely available and can be used by anyone without any royalty fees.
Public Domain, do as you please without any crazy royalty fees!
Note that backports of any modifications are appreciated!
--This is the LÖVE Hello World example updated to use UaLove.
require("ualove")
hook.add("draw", function()
love.graphics.print("Hello World!", 400, 300)
end, "hello-draw")
