Bonjour,
Je cherche à faire un bouton de connexion automatique à un serveur , en 1.6 je n’avais aucun problème mais lorsque j’essaye en 1.7 cela bug
J’ai essayé avec :
this.mc.displayGuiScreen(new GuiConnecting(this, this.mc, new ServerData("Local", "localhost:25565")));
et
mc.displayGuiScreen(new GuiConnecting(this, mc, "localhost", 25565));
J’ai cherché dans les logs mais je ne vois pas comment arranger ça

Si vous avez une idée ce serait d’une grande aide 
Merci d’avance
Tu n’as qu’à regarder la méthode dans GuiMainMenu
Nul part dans GuiMainMenu il n’y a de bouton de connexion automatique ._.
De plus j’ai cherché avec de demander de l’aide ^^’
car c’est pas comme ca qu’il faut faire:
dans
private void addSingleplayerMultiplayerButtons(int par1, int par2) { }
met:
this.buttonList.add(new GuiButton(id_du_bouton, this.width / 2 - 100, par1 + par2 * 1, I18n.getString("Nom_du_serveur"))); this.width / 2 - 100, par1 + par2 * 1 // permet de mettre le bouton au dessus de celui pour multiplayer
et enfin dans ```java
protected void actionPerformed(GuiButton button)
{
}
tu met:```java if (button.id == id_du_bouton) { this.mc.displayGuiScreen(new GuiConnecting(this, mc, "ton_ip", 25565)); }
^^’ c’est ce que j’ai fait
Le problème ne viens pas du bouton mais de ce qu’il effectue , je ne sais pas pourquoi cela ne marche pas ….
car c’est pas comme ca qu’il faut faire:
Je ne comprends vraiment pas de quoi tu parles ^^’
dans ta classe customGuiMainMenu il te faut ajouter les fonction/condition où je te le dit
Je crois que la méthode pour se connecté a changé en 1.7 avec le nouveau système de forge, je vais jeter un coup d’œil.
@‘isador34’:

Là n’est pas le problème
Le bouton marche très bien et mes fonctions/conditions y sont
Lorsque le serveur est éteint je n’ai aucun problème

Merci 
Ok autant pour moi
Perso moi j’ai fait sa et sa bug pas, tout fonctionne très bien !
Premièrement dans le private void addSingleplayerMultiplayerButtons, j’ai fait sa
Cette fonction sert a créer ton bouton et de la déplacer etc…Bref, je crois tu sais !
private void addSingleplayerMultiplayerButtons(int par1, int par2) { this.buttonList.add(new GuiButton(2, this.width / 2 - 100, par1 + par2 * 1, ("NOM TON SERVER"))); fmlModButton = new GuiButton(1, this.width / 2 - 100, par1 + par2 * 0, "Jouer solo"); this.buttonList.add(fmlModButton); }
et après j’ai fait sa dans le protected void actionPerformed
Cette fonction est ton bouton qui se connecte a ton serveur !
protected void actionPerformed(GuiButton button) { if (button.id == 2) { this.mc.displayGuiScreen(new GuiConnecting(this, mc, "IP_TON_SERVER", PORT_TON_SERVER)); } }
Perso moi sa marche sa j’ai aucun problème !
J’ai marqué que j’ai déjà essayé en haut ^^’
Le truc c’est que le bouton marche bien , mais quand le serveur et allumé cela bug et affiche une erreur
tu as un nom de domaine pour ton serv?
non mais j’ai essayé avec plusieurs ip :
un petit serveur en localhost
mon serveur
et Hypixel , ça reviens à la même chose
Bonsoir,
J’ai exactement le même problème, impossible que le bouton marche, voici mon crash report (j’ai les mêmes messages que l’auteur dans ma console) :
if (p_146284_1_.id == 5) { this.mc.displayGuiScreen(new GuiConnecting(this, mc, "37.59.2.220", 2)); }
