Краш при выборе сервера в GuiMultiplayer

[will0376]

Добра всем. Пытаюсь перекинуть GuiMultiplayer к себе в мод(у класса название custGuiMultiplayer), для модифицирования класса.НО при выборе любого сервера происходит краш.
Краш:

Код эвента:

    @SubscribeEvent(priority = EventPriority.HIGHEST, receiveCanceled = true) //   не работает выбор серверов.
    public void OpenGuiMultiplayer(GuiOpenEvent event)
    {
        if (event.gui  instanceof GuiMultiplayer)

            event.gui = new custGuiMultiplayer(new custGuiMainMenu());
        }   
        
        
    }

Что делать то?

 

[Erumind]

Попробуй снести и просто прокопируй классы (изменяя названия), там же измени импорты на свои классы. (В моем случае я тупо всю клиент часть гуи скопировал в отдельный пакет) и не парился.

Ты скорее всего когда исправлял ошибочки поставил нал где-либо. А при нажатии у тебя нул и вызывается.

p.s у меня все работает

 

[will0376]

@SubscribeEvent(priority = EventPriority.HIGHEST, receiveCanceled = true)
    public void OpenGuiMultiplayer(GuiOpenEvent event) {
        if (event.gui  instanceof GuiMultiplayer) {
            event.gui = new custGuiMultiplayer(new custGuiMainMenu(((GuiMultiplayer)event.gui).field_146798_g));
        }
    }

The constructor custGuiMainMenu(GuiScreen) is undefined Разобрался. Но все-равно крашит. =0

Попробуй снести и

бредово выглядит, не правда ли? =\ Я вот уж никак не хочу потом компилировать и отдельно кидать в сурсы кубача

 

[timaxa007]

Могу ещё посоветовать:
с

public class custGuiMultiplayer extends GuiScreen implements GuiYesNoCallback

на

public class custGuiMultiplayer extends GuiMultiplayer

Если снова будет краш то тут разбираться будет нужно, в чём проблема.

Дело трех минут? Ну если вас устраивает, то можете разбирать велосипед, который вы сотворили. Это быстрей )))
