Bug Title 1.7.10

robin4002

Faut trouver alors pourquoi ton joueur renvoie null.
Et bon, à l’intérieur de la classe commande base il y a une fonction pour avoir l’instance du joueur à l’aide du pseudo, je ne sais pas pourquoi tu t’embête avec une nouvelle fonction.

impuuu

tu veut dire sa
public static EntityPlayerMP getPlayer(ICommandSender p_82359_0_, String p_82359_1_)
{
EntityPlayerMP entityplayermp = PlayerSelector.matchOnePlayer(p_82359_0_, p_82359_1_);

if (entityplayermp != null)
{
return entityplayermp;
}
else
{
entityplayermp = MinecraftServer.getServer().getConfigurationManager().func_152612_a(p_82359_1_);

if (entityplayermp == null)
{
throw new PlayerNotFoundException();
}
else
{
return entityplayermp;
}
}
}

Deleted

Oui, c’est cette fonction.

impuuu

en gros
quand je change le entityplayer par
EntityPlayerMP p = getPlayer(sender, command[0]);

sa me souligne le get player
sa me mais The method getPlayer(ICommandSender, String) is undefined for the type CommandSendMessage

Deleted

Normale. La méthode getPlayer provient de la classe CommandBase et non de l’interface ICommand.

impuuu

dans le la class icommand appart le isUsernameIndex et addTabCompletionOptions

@‘impuuu’:

dans le la class icommand appart le isUsernameIndex et addTabCompletionOptions

J’ai déjà dit que cette façon de faire des paquets ne doit plus être utilisé …

impuuu

ok je remplace par quoi il a tuto sur le forum ?

BrokenSwing

@‘robin4002’:

Couldn’t process command: ‘title test test 5 Player33’
Regardes le chat, ton pseudo c’est Player481. Donc normal que Player33 est null.
Si tu avais fait un peu mieux la commande tu aura renvoyé un message “le joueur n’existe pas” si player est null.

Tu pourrai aussi compléter la fonction addTabCompletionOptions et la fonction isUsernameIndex.

Et en passant, tu utilises une vieille implémentation de paquet qui est mauvaise car elle cause des fuites de mémoire.
Le tutoriel de blackout sur le forum explique comme bien faire.
