Résolu Commande inutilisable
-
Bonjour,
J’essaie de créer une commande pour incrémenter une valeur(capability) du joueur.
Ici de la money.
Problème : quand je lance la commande, j’ai une erreur sur le jeu : an error occured…
Et une autre dans la console :java.lang.ArrayIndexOutOfBoundsException: 0 at com.drastic.redskyll.commands.CommandMoney.execute(CommandMoney.java:31) ~[CommandMoney.class:?] at net.minecraft.command.CommandHandler.tryExecute(CommandHandler.java:126) [CommandHandler.class:?] at net.minecraft.command.CommandHandler.executeCommand(CommandHandler.java:98) [CommandHandler.class:?] at net.minecraft.network.NetHandlerPlayServer.handleSlashCommand(NetHandlerPlayServer.java:1005) [NetHandlerPlayServer.class:?] at net.minecraft.network.NetHandlerPlayServer.processChatMessage(NetHandlerPlayServer.java:981) [NetHandlerPlayServer.class:?] at net.minecraft.network.play.client.CPacketChatMessage.processPacket(CPacketChatMessage.java:47) [CPacketChatMessage.class:?] at net.minecraft.network.play.client.CPacketChatMessage.processPacket(CPacketChatMessage.java:8) [CPacketChatMessage.class:?] at net.minecraft.network.PacketThreadUtil$1.run(PacketThreadUtil.java:21) [PacketThreadUtil$1.class:?] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) [?:1.8.0_251] at java.util.concurrent.FutureTask.run(FutureTask.java:266) [?:1.8.0_251] at net.minecraft.util.Util.runTask(Util.java:53) [Util.class:?] at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:798) [MinecraftServer.class:?] at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:743) [MinecraftServer.class:?] at net.minecraft.server.integrated.IntegratedServer.tick(IntegratedServer.java:192) [IntegratedServer.class:?] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:592) [MinecraftServer.class:?] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_251] [18:38:35] [Server thread/INFO] [STDOUT]: [com.drastic.redskyll.commands.CommandMoney:execute:37]: give [18:38:35] [Server thread/WARN] [minecraft/CommandHandler]: Couldn't process command: eco give java.lang.ArrayIndexOutOfBoundsException: 1 at com.drastic.redskyll.commands.CommandMoney.execute(CommandMoney.java:38) ~[CommandMoney.class:?] at net.minecraft.command.CommandHandler.tryExecute(CommandHandler.java:126) [CommandHandler.class:?] at net.minecraft.command.CommandHandler.executeCommand(CommandHandler.java:98) [CommandHandler.class:?] at net.minecraft.network.NetHandlerPlayServer.handleSlashCommand(NetHandlerPlayServer.java:1005) [NetHandlerPlayServer.class:?] at net.minecraft.network.NetHandlerPlayServer.processChatMessage(NetHandlerPlayServer.java:981) [NetHandlerPlayServer.class:?] at net.minecraft.network.play.client.CPacketChatMessage.processPacket(CPacketChatMessage.java:47) [CPacketChatMessage.class:?] at net.minecraft.network.play.client.CPacketChatMessage.processPacket(CPacketChatMessage.java:8) [CPacketChatMessage.class:?] at net.minecraft.network.PacketThreadUtil$1.run(PacketThreadUtil.java:21) [PacketThreadUtil$1.class:?] at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) [?:1.8.0_251] at java.util.concurrent.FutureTask.run(FutureTask.java:266) [?:1.8.0_251] at net.minecraft.util.Util.runTask(Util.java:53) [Util.class:?] at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:798) [MinecraftServer.class:?] at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:743) [MinecraftServer.class:?] at net.minecraft.server.integrated.IntegratedServer.tick(IntegratedServer.java:192) [IntegratedServer.class:?] at net.minecraft.server.MinecraftServer.run(MinecraftServer.java:592) [MinecraftServer.class:?] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_251]Mon code :

Bonsoir,
Quel est la ligne 31 ? (comme tu n’as pas mis les importations, elles ne correspondent pas avec ce qui est affiché). -
@robin4002 Désolé ^^

Ton code a changé depuis que tu as eu le rapport de crash ? Car je ne vois pas comment tu peux avoir un ArrayIndexOutOfBoundsException sur ta ligne 31 sachant qu’il n’y a aucune array à cette ligne.
Cela semble plutôt être la ligne 29 :String s = args[0];Et si tu as cette erreur, c’est probablement car tu n’as pas mis d’argument lorsque tu as tapé ta commande.
-
@robin4002 pas possible de rendre des arguments non obligatoires ?
-
Si, pour cela il faut que tu adapte ton code.
Il faut commencer avec un if sur args.length et ensuite tu adapte ta logique en fonction du nombre d’arguments.

@robin4002 j’ai modifié mon code mais maintenant le jeu me met toujours “format incorrect” quel que sois le premier arg

Est-ce qu’il y a une erreur dans la console ?
-
@robin4002 non

@robin4002 il détecte pas que c’est le bon texte

Attention par contre, au début de ta fonction execute il faut faire le cast après le check d’instance, comme ceci :
if(player instanceof EntityPlayerMP) { EntityPlayerMP player = (EntityPlayerMP)sender;Sinon tu vas avoir une erreur si tu utilises la commande depuis la console du serveur.
