-- `Controller`
-- Module to manage player input.
-- It uses `love.keypressed`, `love.keyreleased`, `love.gamepadreleased`, `love.gamepadpressed`, `love.joystickadded`, so be sure not to use them by yourself.
-- Rather than that use functions provided by this module: `Controller.controlpressed` and `Controller.controlreleased`.
-- For information on additional functions, look below.
-- Metatable

sets = {}
}
-- Declared to avoid calling nil. Be sure to define yours after this line is performed.
