local lastbutton = "none"

function love.gamepadpressed(joystick, button)
    lastbutton = button
end

function love.draw()
    love.graphics.print("Last gamepad button pressed: "..lastbutton, 10, 10)
end

Move a circle with the d-pad of a controller

function love.load()

    joystick = joysticks[1]

    position = {x = 400, y = 300}
    speed = 300
end

function love.update(dt)
