c'est notre premier projet.. on n'a pas beaucoup d'idées pour le langage java..pour l'enchainement d'actions avec des ifs on n'a pas trouvé des solutions pour ça.on a forcé de dessiner les fleches dans des intervalles connues puisqu'on sait les echanges des fleches entre les entités comment..mais on n'a pas trouvé honnetement que de faire ça..
