Фильтр мода. ParentMod

[Vector_admin123]

Привет всем. Да-да это снова я.

На этот раз вопрос таков-Есть мод который выдаёт абсолютно рандомные предметы. Хочу запретить выдачу микроблоков. Пробовал через ParentMod,но происходит краш... Хелпуйте плиз!

Замени
if (ParentMod.getModId()!="ForgeMicroblock")
На
if (!ParentMod.getModId().equalsIgnoreCase("ForgeMicroblock")

У меня есть предположение, что ванилла предметы не возвращают ModContainer, так что проверяй его на null.

    @Override
    public ItemStack onItemRightClick(ItemStack is, World w, EntityPlayer p) {
        if (!w.isRemote) {
            EntityItem ei = new EntityItem(w, p.posX, p.posY, p.posZ, select(w, 1));
            ei.delayBeforeCanPickup = 0;
            w.spawnEntityInWorld(ei);
        }
        return is;
    }

    private ItemStack select(World w, int i) {
        Item item = null;
        while (item == null) {
            Item ret = (Item) Item.itemRegistry.getObjectById(w.rand.nextInt(Item.itemRegistry.getKeys().size()));
            if (ret != null && !GameRegistry.findUniqueIdentifierFor(ret).modId.equalsIgnoreCase("ForgeMicroblock"))
                item = ret;
        }
        return new ItemStack(item, i);
