La fonction principale du module love.graphics est le dessin de lignes, formes, textes, Images et autres objets Drawable à l'écran. Ses autres fonctionnalités comprennent le chargement de fichiers externes (Images et Fonts) en mémoire, la création d'objets spécialisés (comme un ParticleSystems ou un Canvas) et la gestion de l'écran.

Le système de coordonnées de LÖVE à pour origine le coin supérieur gauche de l'écran, à la position (0, 0). L'axe des abscisses x est horizontal, les valeurs augmentent vers la droite. L'axe des ordonnées y est vertical, les valeurs augmentent vers le bas.

The LÖVE coordinate system

Dans la plupart des cas, les images ou les formes sont dessinées à partir de leur coin supérieur gauche (Voir image ci-dessus).

Beaucoup de fonctions sont utilisées pour manipuler le système de coordonnées graphiques, essentiel pour la façon dont les coordonnées sont disposées sur l'écran. On peut alors changer la position, mettre à l'échelle ou faire pivoter un objet.
