[1.7.10] Краш при добавлении вкладки

BlackCrafter · 30 Май 2015

нужно добавить вкладку в креатив и взять иконку от блока.

Код:

    final CreativeTabs tabxxx = new CreativeTabs("xxx") {
        @Override
        @SideOnly(Side.CLIENT)
        public Item getTabIconItem() {
            return Item.getItemFromBlock(blockBlue);
        }

    };

Почему крашит?

но мой блок не равен null. Смотрел в дебаггере.

А что раньше регистрирукшь? Блок или вкладку? Надо блок

у меня в коде идет сначала вышеуказанная конструкция, потом FMLInitializationEvent.
При выполнении return Item.getItemFromBlock(blockWhite), блок по-идее уже зарегистрирован. Это видно в дебаггере.
Дебаггер доходит до метода

Код:

    public int func_148747_b(Object p_148747_1_)
    {
        Integer integer = (Integer)this.field_148749_a.get(p_148747_1_);
        return integer == null ? -1 : integer.intValue();
    }

и тут получается -1
[merge_posts_bbcode]Добавлено: 30.05.2015 15:41:51[/merge_posts_bbcode]

если вынести вкладку в отдельный класс и делать

Код:

    final CreativeTabs tabxxx = new Tab1("yyyyyy");

тогда работает.
но почему?

timaxa007 · 30 Май 2015

Типа я не знаю как правильно объяснить. Но постараюсь понятнее.

Код:

Item.getItemFromBlock(blockBlue);

Тут ты не указал главный класс, а просто переменную. Если до этого момента переменная "blockBlue" не равен нулевому значению, то краша про нулевое значение не было. Но тогда из-за листа, этого блока не было во вкладке.
Когда ты сделал отдельный класс для вкладки, то ты указал главный класс и переменную, то тут зависит от условий, если переменная "blockBlue" будет не нулевому значению, до того как будет вызван метод, который требует переменную "blockBlue", то краша не должно.
[merge_posts_bbcode]Добавлено: 30.05.2015 12:02:05[/merge_posts_bbcode]

Т.е. типа надо указать кроме переменной и ещё класс этой переменной, даже если эта переменная находиться в этом-же классе.

BlackCrafter · 30 Май 2015

Да, но ведь public Item getTabIconItem() вызывается не при загрузке мода, а при перелистывании инвентаря в игре. То есть, к этому моменту все блоки уже давно зарегистрированы.
p.s. Аккуратно переписал код еще раз. Всё работает без класса вкладки. Так и не понял, где ошибка была.
