Description

Gestion des animations de sprites et sonorisation au travers d'une classe Java complète. Utilisable en active et passive rendering (grâce au composant étendu JComponent), le tout Double-Buffering pour assurer le polissage du rendu.
Le tampon mémoire est celui disponible dans le meme package sf3.*, nommée SpritesCacheManager elle sert de tampon ou cache selon les options fournies. Toutes les classes présentées sont Serializable ce qui permet de garder une certaine intégrité à tout ce concept. :)

(ajout: sept 2007 - l'animation devient plus fluide avec un MediaTracker centralisé. Toutefois, il serait nécessaire de vérifier le hashCode du mediatracker qui semble ne pas respecter le contrat de la fonction equals(), cette dernière devrait être surchargée pour retourner une égalité lorsque le même MediaTracker est annoncé pour chaque Sprite, or cela ne semble pas être le cas. Une ré-implementation du MediaTracker est à voir donc. )
