Here is most of my mod class:

public class Circuitry {
    public static final String MODID = "circuitry";

    private static final DeferredRegister<Block> BLOCKS = new DeferredRegister<>(ForgeRegistries.BLOCKS, MODID);
    public static final RegistryObject<Block> IN_NODE = BLOCKS.register("in_node", InNodeBlock::new), OUT_NODE = BLOCKS.register("out_node", OutNodeBlock::new);

    public Circuitry() {
		DeferredRegister<Item> items = new DeferredRegister<>(ForgeRegistries.ITEMS, MODID);
		BLOCKS.getEntries().forEach(block -> items.register(block.getId().getPath(), () -> new BlockItem(block.get(), new Properties().group(ItemGroup.REDSTONE))));

		IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();
		bus.register(BLOCKS);
		bus.register(items);
	}
}

 

I have the Item DeferredRegister and RegistryObjects in the constructor rather than statically declaring it because I never need to retrieve the Item objects anywhere else in my code. However, upon loading a world, I am unable to find any of the added Blocks in the Redstone tab of the creative menu. The following commands don't work either:

/give Dev circuitry:in_node
/give Dev circuitry:out_node

 

Declaring the Item DeferredRegister and RegistryObjects statically doesn't seem to fix the problem either. Printing the Item DeferredRegistry shows two entries with the correct names.

 

No error messages are thrown and I can't determine why this is occurring.

You registered them in the wrong way.

Because when this line runs:

Your BLOCKS contains no entries because block registration hasn't happened yet.

Register your stuff properly.

Well, when I iterate through the BLOCKS entries, it shows two RegistryObjects in it. After running the command to create items as I did, there are two RegistryObjects in the items entries. They all have the correct names as well. It seems functionally identical to defining them as so:

public Circuitry() {
	DeferredRegister<Item> items = new DeferredRegister<>(ForgeRegistries.ITEMS, MODID);
	items.register("in_node", () -> new BlockItem(IN_NODE.get(), new Properties().group(ItemGroup.REDSTONE)));
	items.register("out_node", () -> new BlockItem(OUT_NODE.get(), new Properties().group(ItemGroup.REDSTONE)));

	IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();
	bus.register(BLOCKS);
	bus.register(items);
}

and even doing this statically like so:

public class Circuitry {
	private static final DeferredRegister<Block> BLOCKS = new DeferredRegister<>(ForgeRegistries.BLOCKS, MODID);
	private static final DeferredRegister<Item> ITEMS = new DeferredRegister<>(ForgeRegistries.ITEMS, MODID);

	public static final RegistryObject<Block> IN_NODE = BLOCKS.register("in_node", InNodeBlock::new), OUT_NODE = BLOCKS.register("out_node", OutNodeBlock::new);

	static {
		ITEMS.register("in_node", () -> new BlockItem(IN_NODE.get(), new Properties().group(ItemGroup.REDSTONE)));
		ITEMS.register("out_node", () -> new BlockItem(OUT_NODE.get(), new Properties().group(ItemGroup.REDSTONE)));
	}

	public Circuitry() {
		IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();
		bus.register(BLOCKS);
		bus.register(ITEMS);
    }
}

Even writing it identical to how the documentation does it doesn't help:

public class Circuitry {
    private static final DeferredRegister<Block> BLOCKS = new DeferredRegister<>(ForgeRegistries.BLOCKS, MODID);
    private static final DeferredRegister<Item> ITEMS = new DeferredRegister<>(ForgeRegistries.ITEMS, MODID);

    public static final RegistryObject<Block> IN_NODE_BLOCK = BLOCKS.register("in_node", InNodeBlock::new), OUT_NODE_BLOCK = BLOCKS.register("out_node", OutNodeBlock::new);
    public static final RegistryObject<Item> IN_NODE_ITEM = ITEMS.register("in_node", () -> new BlockItem(IN_NODE_BLOCK.get(), new Properties().group(ItemGroup.REDSTONE))), OUT_NODE_ITEM = ITEMS.register("out_node", () -> new BlockItem(OUT_NODE_BLOCK.get(), new Properties().group(ItemGroup.REDSTONE)));

    public Circuitry() {
		IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();
		bus.register(BLOCKS);
		bus.register(ITEMS);
    }
}

Alright. But that still doesn't help because none of the methods I tried work.

This is not how your register a DefferedRegister to the event bus.

Oh jeez, that was a stupid mistake. I should not have been writing late t night. Thank you.
