Je viens de comprendre le problème. Tu as enregistré deux paquets avec le même discriminateur. Du-coup ça fou la merde.
(        network.registerMessage(PacketMana.Handler.class, PacketMana.class, 2, Side.SERVER); remplace 2 par 1 ici)

[sosoh]

Ah ok merci !  C’est pas moi qui ai fait le systeme pour les packets la 1ere fois et je ne maitrise pas… Mais c’est quoi un discriminateur ? ^^

Bah tant qu’à faire tu peux dire que c’est moi qui l’ai fait x)
Et pour répondre à ta question un discriminateur c’est une sorte d’id pour les packets.

id* et merci  (PS: je commece le systeme pour gerer les sorts, la selection etc…)
