Recommended Posts

Hello, i created a custom tab and custom items and when i open CreativeInventory, i see a my items in all tabs. How to fix it?

Code Item:

class ItemMoney: Item
{
    init
    {
        this.setRegistryName("money");
        this.setUnlocalizedName("money");
        this.setCreativeTab(Crank.tab);
        this.setHasSubtypes(true);
    }

    override fun getSubItems(tab: CreativeTabs, subItems: NonNullList<ItemStack>)
    {
        MoneyType.values().mapTo(subItems) { ItemStack(this, 1, it.meta) }
    }

    override fun getUnlocalizedName(stack: ItemStack?): String
    {
        return super.getUnlocalizedName() + "." + MoneyType.byMetadata(stack!!.metadata).getName()
    }
}

Code Tab:

class CustomTab: CreativeTabs("customtab")
{
    override fun getTabIconItem(): ItemStack
    {
        return ItemStack(Items.APPLE)
    }
}

    }
}

I'm pretty sure we do Java here, not other Programming Languages :/

I think that's Kotlin, which can cross-compile to Java. Don't quote me on that though.

 

Anyway, the problem is here:

getSubItems(tab: CreativeTabs

ALL items have this method called for ALL tabs, which tab is the current one is passed in in this parameter. If you want to only have your item show up in one tab, you need to only return your item stack list when that tab is active.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

Thanks, it is working.
