Je peux te proposer la classe que je viens juste de finir d'ecrire si tu veux.
Ce n'est qu'une vulgaire modification de la classe Box deja existante.
J'ai ajouté les methodes suivantes :
Action Script
public function addLeftFace(_value:Number)
public function addRightFace(_value:Number)
public function addFrontFace(_value:Number)
public function addBehindFace(_value:Number)
public function addTopFace(_value:Number)
public function addBottomFace(_value:Number)
Edit : elles permettent de modifier la taille du Box depuis une certaine face
PS: Penses à renommer le fichier sandy/primitive/Box.as avant de copier le nouveau
PS2: la piece jointe ne passe pas alors voila :
Action Script
