Okay, so - I have an item "craftablechainmail:chainmail_plate". I want to change the repair item of chainmail armor to this item.

...how do I do this?

Gotcha. So, do that in an event that's run after item registration, which would be...? Is there an event list sorted by order?

This doesn't seem to work...

@ObjectHolder(MODID)
public static final Item CHAINMAIL_PLATE = null;

public ExampleMod() {
	FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
}

private void setup(FMLCommonSetupEvent e) {
	DeferredWorkQueue.runLater(ExampleMod::doReplaceChainmailRepairMaterial);
}

private static final String OBSFUCATED_FIELD_NAME_ARMORMATERIAL_REPAIRMATERIAL = "field_200914_m";

static void doReplaceChainmailRepairMaterial() {
	try {
		ObfuscationReflectionHelper.setPrivateValue(
				ArmorMaterial.class,
				ArmorMaterial.CHAIN,
				new LazyLoadBase<>(() -> Ingredient.fromItems(CHAINMAIL_PLATE)),
				OBSFUCATED_FIELD_NAME_ARMORMATERIAL_REPAIRMATERIAL);
	} catch(ObfuscationReflectionHelper.UnableToFindFieldException e) {
		throw new RuntimeException("Could not find field ArmorMaterial.CHAIN.repairMaterial", e);
	} catch(ObfuscationReflectionHelper.UnableToAccessFieldException e) {
		throw new RuntimeException("Could not access field ArmorMaterial.CHAIN.repairMaterial", e);
	}
}

No exceptions, it just doesn't have any effect in-game.

You are not using @ObjectHolder correctly. When put in a field it must hold a registry name, not a resource domain.

So it was staying "null", and some part of the process detected that and undid it or something??? Because I saw no NPEs in the log. Regardless... whoops.

@ObjectHolder("MOD_ID_HERE");
class ModThing {
	@ObjectHolder("ITEM_REGISTRY_NAME_HERE");
	public static final Item ITEM_THINGY = null;
}

Is this how it's done, or does

@Mod

imply

@ObjectHolder

?

Any reason you are not using DeferredRegister?

I had no idea it existed. Will change to it.

Yes, thats how you would do it.

 

 

No.

Well that's... confusing.

Well whatever, this is what I do now:

public static final DeferredRegister<Item> ITEMS = new DeferredRegister<>(ForgeRegistries.ITEMS, MODID);

public static final RegistryObject<Item> CHAINMAIL_PLATE = ITEMS.register("chainmail_plate", () -> new Item(new Item.Properties().group(ItemGroup.MISC)));

Anyway, it works now! Only problem is that JEI still shows iron ingots in the repair recipe.

Here's a correct @ObjectHolder annotation.
