En faite c'est très simple, ton programme permet de créer une aventure aléatoire dans une ville que tu simules(de très grande taille apparemment). Dans ton premier package tu as crée des attributs variables ( oups j'ai oublié de te dire que c'était dans la deuxième classe crée) avec ces attributs tu as crée les personnages de ton aventure aléatoire. C'est parti nos courageux aventuriers sont lancés ( leur niveau et capacités sont en attribut 4eme classe en tournant à gauche).
