1. La map doit être stockée côté serveur, ça sert absolument à rien de la mettre dans le GUI.
2. Tu utilises ‘Minecraft::thePlayer’, mais es-tu sûr qu’il existe? Parce que si ton GUI est ouvert sans être dans un monde MC, thePlayer renvoit null. Pour récupérer l’ID du joueur, utilise plutôt GameProfile (il y a un getter dans Minecraft de mémoire)

Quand tu dis stockée une map côté serveur tu peux t’expliqué mieux je comprends pas ou je peux la stocké.

Oui mon gui est ouvert sans êtres dans un monde mc se qui explique le crash d’accord !

Avec GameProfile je peux avoir l’uuid du joueur du coup ?

jglrxavpok

Pour le GameProfile, oui

Pour la map côté serveur, dans ton proxy serveur (par exemple), fais une map et ajoute lui du contenu lorsque tu reçois un packet pour les noms.

Le problème, c’est que “actionPerformed” est appelé coté client et que tu essaye d’accéder au serveurProxy.
Pour pouvoir t’aider, j’ai juste une petite question : ton gui s’ouvre lorsque l’on est dans un monde ou on est sur le menu principale ?
- Si tu est sur un monde, alors tu envoie un packet au serveur avec le Nom que le joueur a choisi et le serveur s’occupera d’enregistrer le nom dans la map du serveurProxy.
- Si tu est sur le menu principale, il faut enregistrer le nom coté client et l’envoyer au serveur quand tu t’y connecte.

Je suis sur le menu principal donc j’enregistrer le nom côté client c’est a dire que le server proxy on laisse, je met ma map dans mon guiscreen je put donc l’id du joueur avec son nom_prénom et une fois que il se connecte au serveur j’envoie son nom_prénom par un packet au serveur c’est ça?

Oui et non : Coté client : tu laisse le serveur proxy, tu n’a pas besoin d’une map vu que tu n’a qu’un nom à enregistrer tu met juste une variable de type String. Et ne la met pas dans ton guiscreen car quand le joueur aura fermé le gui, tu n’aura plus le nom. Il faut donc l’enregistrer quelque par comme sur le client proxy, si tu veux. ( et pas besion de l’id du joueur coté client)
Ensuite tu envoi juste le nom_prenom par un packet quand le joueur se connecte et coté serveur, tu ajoute le nom_prenom avec l’id du joueur dans la map du serveur proxy.

D’accord je vois,

le seul truc que je comprends pas c’est: je dois utiliser obligatoirement cet event pour le changement de pseudo: PlayerEvent.NameFormat .

Mais toi tu me dis d’envoyer côté client le string du nom_prénom quand le joueur se connecte et côté serveur ajouter le nom_prénom et l’UUID du joueur dans la map mais pour cela je dois utiliser cet event : PlayerEvent.PlayerLoggedInEvent . Comment je peux faire du coup ?

robin4002

Tu peux très bien faire les deux.
Envoyer le nom lors du login au serveur puis avec PlayerEvent.NameFormat changer le nom.

Je ne vois pas ce qui cause problème.

Help ?

robin4002

Je viens de faire quelque vérification, PlayerEvent.NameFormat est un event commun (client et serveur) donc ce que tu as fait actuellement ne risque pas de fonctionner.

Il faudrait plutôt :

garder dans une variable client le pseudo changé et l’envoyer au serveur lors de la connexion (voir simplement proposer le changement de pseudo uniquement si on est sur le serveur et l’envoyer directement).
sauvegarder côté serveur le pseudo dans une map de joueur + l’enregistrer dans le monde ou enregistrer directement dans le nbt du joueur (pas besoin de map alors)
envoyer également au client son pseudo custom lors de la connexion.

@‘robin4002’:

Je viens de faire quelque vérification, PlayerEvent.NameFormat est un event commun (client et serveur) donc ce que tu as fait actuellement ne risque pas de fonctionner.

Il faudrait plutôt :

garder dans une variable client le pseudo changé et l’envoyer au serveur lors de la connexion (voir simplement proposer le changement de pseudo uniquement si on est sur le serveur et l’envoyer directement).

sauvegarder côté serveur le pseudo dans une map de joueur + l’enregistrer dans le monde ou enregistrer directement dans le nbt du joueur (pas besoin de map alors)

envoyer également au client son pseudo custom lors de la connexion.

Je vais faire comme tu as dis ça a l’air plus simple. “(voir simplement proposer le changement de pseudo uniquement si on est sur le serveur et l’envoyer directement)”
Donc j’ouvre mon gui quand je me connecte.
Une fois ouvert je choisis mon nom puis prénom, je valide…
J’envois donc un packet au serveur contenant deux string, L’UUID et le nom et le prénom espacé d’un tiré du 8 (Nom + “_” + Prénom)
Dans ce packet j’ajoute tout ça dans une hashmap qui se situe dans le ServerProxy.
L’event NameFormat récupére donc le nom et prénom du joueur via la hashmap
et j’ai pas fais le reste…

Je crash au moment de validé mon nom prénom. (au moment ou j’envois ça au serveur avec le packet)

Je vous passe mon gui et mon packet:

Ton instance n’est jamais initialisé.

Gabs

@‘robin4002’:

Ton instance n’est jamais initialisé.

Pourtant elle est initialisé la:


if(NameSave.instance != null)
        {
        NameSave.load(event.getServer().getEntityWorld());
        }

J’ai remplacer le != par == pour voir si ça régler mon problème, j’ai un autre crash mais maintenant quand je me connecte:
