Ouvrir un GUI quand un texte apparait dans le chat

[PlayFlop_]

Bonjour,
J'ai fait pas mal de recherches et je ne trouve que ce code.
Qui de mon coté ne fonctionne pas.

Je voudrais ouvrir un GUI quand un texte apparait dans le chat.
Je me connecte a un serveur et la par exemple il y a "Please register …..."
Et dés que le message apparait, ça ouvre le menu GUI

  @SideOnly(Side.CLIENT)
  @SubscribeEvent
  public void onClientChatMessage(ClientChatReceivedEvent event)
  {
          if(event.message.getFormattedText().startsWith("/login"))
          {
         Minecraft.getMinecraft().displayGuiScreen(new GuiLogin());
          }
  }

Salut, qu'est-ce qui ne va pas avec le code actuel ?

Bha en fait sa n'ouvre pas le gui..
Alors que sur mon serveur j'ai mon plugin qui envoi le message dans le chat. C'est justement pour sa que je ne comprend pas..

Peint dans ton Event le String donné par event.message.getFormattedText() afin de voir s'il commencé réellement par "/login". De mémoire, je crois qu'il commencé d'abord par un crochet suivis du pseudo du sender.

Comment je peut faire ça ?
Je suis pas douer dans ce genre de chose..

La voici:

String message = event.message.getUnformattedText().substring(Minecraft.getMinecraft().getSession().getUsername().length() + 3, event.message.getUnformattedText().length());

[robin4002]

Tu essaies de coupe une partie de chaine plus grande que la chaine elle même.
Avant de faire ce code il faudrait la condition suivante :
if(message.length() > Minecraft.getMinecraft().getSession().getUsername().length() + 3)

pour éviter ce crash;

Le truc c'est que je veux pas diviser la ligne

Hein ? Je ne comprends pas le problème.
