Quando si inizia a sviluppare giochi con LÖVE, il primo passo è prendere confidenza con le callback fondamentali: love.load per preparare il gioco, love.update per gestire cosa succede ad ogni frame, e love.draw che riporta sullo schermo l'aspetto grafico.

Giochi più interattivi richiederanno l'uso di altre callback, ad esempio quelle per ricervere l'input dell'utente o riguardanti altri aspetti di un gioco completo. Queste callback sono elencate più avanti.

LÖVE fornisce degli scheletri per ognuna di queste callback, che puoi riempire come preferisci all'interno del tuo codice. Tutto ciò che devi fare, è definire una funzione con un nome identico alla callback in questo modo:

-- Impostiamo dei valori default per il nostro rettangolo.
function love.load()
    x, y, w, h = 20, 20, 60, 20
end

-- Incrementiamo le dimensioni del rettangolo ad ogni frame.
function love.update(dt)
    w = w + 1
    h = h + 1
end

-- Disegnamo il rettangolo, dandogli un colore a piacere.
function love.draw()
    -- Nelle versioni precedenti alla 11.0, i valori del colore sono (0, 102, 102)
    love.graphics.setColor(0, 0.4, 0.4)
    love.graphics.rectangle("fill", x, y, w, h)
end
