Je ne vois pas comment on peut être plus explicite.

Ta fonction getAliases renvoies null, ce qui cause un npe.
Il faut renvoyer une liste valide.

[En0ri4n]

merci ça marche maintenant !
Mais je n’arrive pas a trouver comment modifier le nom de l’item qui est dans la main,
j’ai essayer ça mais ça ne marche pas :

	public void execute(MinecraftServer server, ICommandSender sender, String[] strings) throws CommandException
	{
		if(sender instanceof EntityPlayer)
		{
			EntityPlayer player = (EntityPlayer) sender;
			String name = player.getActiveHand().MAIN_HAND.name();
			player.inventory.getDisplayName().equals(name);
		}

	}

mais j’aimerais aussi pouvoir mettre le nom de couleur dans laquelle on veut le nom,
par exemple : /rename NomDelItem Couleur EnGras(true ou false)
Est ce que l’on peut le faire ?

[robin4002]

player.inventory.getDisplayName() retourne le nom de l’inventaire et .equals c’est une méthode qui permet de comparer deux objets.

Donc là forcement oui, ton code ne va rien faire.

Il faut plutôt quelque chose comme ceci :

ItemStack stack = player.getHeldItem(EnumHand.MAIN_HAND); // obtient l'item dans la main principale
stack.setStackDisplayName(displayName); // change le nom affiché

Pour récupérer les arguments tapés, c’est ta variable strings qui les contient.
strings[0] -> le premier argument (NomDelItem dans l’exemple que tu as donné)
strings[1] -> le deuxièmeargument (Couleur dans l’exemple que tu as donné)
etc…
Et il faut bien sur vérifier que strings.length ait la bonne valeur avant d’utiliser le string à l’index voulu (sinon ça va déclencher une ArrayOutOfBoundException

[En0ri4n]

yes merci ça marche
mais je n’arrive pas a ajouter la couleur :

public void execute(MinecraftServer server, ICommandSender sender, String[] args) throws CommandException
	{
		if(sender instanceof EntityPlayer)
		{
			EntityPlayer player = (EntityPlayer) sender;
			ItemStack stack = player.getHeldItem(EnumHand.MAIN_HAND); // obtient l'item dans la main principale
			TextFormatting color = TextFormatting.valueOf(args[1]);
			TextFormatting effect = TextFormatting.valueOf(args[2]);
			stack.setStackDisplayName(args[0]); // change le nom affiché

		}

	}

J’ai essayer avec le text formatting mais sans succès (ou alors je l’ai mal fait )
une idée ?

[robin4002]

Le couleur tu veux que l’utilisateur l’écrit avec quel format ? §1 §2 etc. ? ou RED, BLUE, etc. ?

[En0ri4n]

plutot en red, blue, bold,obfuscated
j’aurais voulu additionner comme ça :
/rename [NomDel’Item] blue bold underline

[robin4002]

Pour ça va falloir faire une boucle qui pour chaque args vérifie s’il existe dans les EnumFormatting, et si oui retourner le texte de formatage qui va avec.

[En0ri4n]

et je pourrais faire ça comment par exemple ?

[BrokenSwing]

Salut, c’est une opération assez simple :

def : style
Pour i allant de 1 à (taille(args) - 1):
    Si args[i] dans valeurs(EnumFormatting) :
         def : format = récupérerEnumFormattingDepuisNom(args[i])
         style.ajouterFormat(format)

Voilà, plus qu’à traduire cette logique en Java.

[En0ri4n]

le truc c’est que je suis en train d’apprendre le java et donc je comprends pas trop ou plutot je ne sais pas comment le traduire en java
tu pourrais m’expliquer ?

[SpyMan]

yo sinon tu utilise comme dans tout les plugins le caractere & dans le message ensuite tu le remplace par un § et minecraft fait le formatage tout seul x)

player.getHeldItemMainhand().setStackDisplayName(name.replace('&', '§'));

si tu comprends toujours pas comment faire passe sur le discord et je peux vocal pour plus d’explications x)
