      Coucou le monde, voilà j’ai crée pour mon menu personnalisé un système de connexion inclus directement dans celui-ci :

      Tout fonctionne bien… Quand on se connecte à une partie solo juste avant sinon on a droit à un magnifique NullPointerExeption :

      :::

      Je suppose (grandement) que le problème vient d’un protocole qui retourne NULL à un moment donné mais pourquoi le faire que quand on c’est pas connecté à une partie solo juste avant ?! Voici mon code qui gère tout ça :

      private void initiateServerConnection()

    {
        this.isConnecting = true;
        ((GuiShunayteButton) this.buttonList.get(1)).setVisible(false);
        ((GuiShunayteButton) this.buttonList.get(2)).setVisible(false);
        ((GuiShunayteButton) this.buttonList.get(3)).setVisible(false);
        ((GuiShunayteButton) this.buttonList.get(5)).setVisible(false);

        ((GuiShunayteButton) this.buttonList.get(0)).setButtonName(I18n.format("menu.connect.connecting", new Object[0]));

        ServerAddress serveraddress = ServerAddress.func_78860_a(server.serverIP);
        mc.loadWorld((WorldClient)null);
        mc.setServerData(server);
        this.connectToServer(serveraddress.getIP(), serveraddress.getPort());
        ((GuiShunayteButton) this.buttonList.get(6)).setVisible(true);
    }

    private void connectToServer(final String p_146367_1_, final int p_146367_2_)
    {
        logger.info("Connecting to " + p_146367_1_ + ", " + p_146367_2_);
        (new Thread("Server Connector #" + field_146372_a.incrementAndGet())
        {
            public void run()
            {

                InetAddress inetaddress = null;

                try
                {
                    if (GuiShunayteMainMenu.this.field_146373_h)
                    {
                        return;
                    }

                    inetaddress = InetAddress.getByName(p_146367_1_);

                    GuiShunayteMainMenu.this.field_146371_g = NetworkManager.provideLanClient(inetaddress, p_146367_2_);
                    GuiShunayteMainMenu.this.field_146371_g.setNetHandler(new NetHandlerLoginClient(GuiShunayteMainMenu.this.field_146371_g, GuiShunayteMainMenu.this.mc, GuiShunayteMainMenu.this.screen));

                    GuiShunayteMainMenu.this.field_146371_g.scheduleOutboundPacket(new C00Handshake(5, p_146367_1_, p_146367_2_, EnumConnectionState.LOGIN), new GenericFutureListener[0]);
                    GuiShunayteMainMenu.this.field_146371_g.scheduleOutboundPacket(new C00PacketLoginStart(GuiShunayteMainMenu.this.mc.getSession().func_148256_e()), new GenericFutureListener[0]);

                }
                catch (UnknownHostException unknownhostexception)
                {
                    if (GuiShunayteMainMenu.this.field_146373_h)
                    {
                        return;
                    }

                    GuiShunayteMainMenu.logger.error("Couldn\'t connect to server", unknownhostexception);
                    GuiShunayteMainMenu.this.mc.displayGuiScreen(new GuiDisconnected(GuiShunayteMainMenu.this.screen, "connect.failed", new ChatComponentTranslation("disconnect.genericReason", new Object[] {"Unknown host"})));
                }
                catch (Exception exception)
                {
                    if (GuiShunayteMainMenu.this.field_146373_h)
                    {
                        return;
                    }

                    GuiShunayteMainMenu.logger.error("Couldn\'t connect to server", exception);
                    String s = exception.toString();

                    if (inetaddress != null)
                    {
                        String s1 = inetaddress.toString() + ":" + p_146367_2_;
                        s = s.replaceAll(s1, "");
                    }

                    GuiShunayteMainMenu.this.mc.displayGuiScreen(new GuiDisconnected(GuiShunayteMainMenu.this.screen, "connect.failed", new ChatComponentTranslation("disconnect.genericReason", new Object[] {s})));
                }
            }
        }).start();
    }

      Merci d’avance 😃

        Essaie plutôt çà pour te connecter à un serveur :

        
FMLClientHandler.instance().connectToServerAtStartup(adress, port);

        Ton code devrait ressembler à çà :

        
private void initiateServerConnection()

{
this.isConnecting = true;
((GuiShunayteButton) this.buttonList.get(1)).setVisible(false);
((GuiShunayteButton) this.buttonList.get(2)).setVisible(false);
((GuiShunayteButton) this.buttonList.get(3)).setVisible(false);
((GuiShunayteButton) this.buttonList.get(5)).setVisible(false);

((GuiShunayteButton) this.buttonList.get(0)).setButtonName(I18n.format("menu.connect.connecting", new Object[0]));

FMLClientHandler.instance().connectToServerAtStartup(adress, port);
((GuiShunayteButton) this.buttonList.get(6)).setVisible(true);
}
