Hello. I have been trying to register my own class NBTNoteBlock to the block registry with key note_block in "minecraft" but I got an error. I don't know what was wrong. It would be appreciated if someone could provide a fix. Code is provided below.

 

Error I got was:

[16:41:11] [Render thread/ERROR] [minecraft/Util]: No data fixer registered for note_block
[16:41:11] [Render thread/ERROR] [ne.mi.fm.ja.FMLModContainer/]: Exception caught during firing event: Can not register to a locked registry. Modder should use Forge Register methods.

 

First few lines in the main mod file:

// The value here should match an entry in the META-INF/mods.toml file
@Mod("nbaddons")
public class nbaddons {
    // Directly reference a log4j logger.
    public static final Logger LOGGER = LogManager.getLogger();
    public static final String MOD_ID = "nbaddons";

    public nbaddons() {
        Registration.register(); // <-- Registers stuff, see Registration.java

        // Register the setup method for modloading
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        // Register the doClientStuff method for modloading
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::doClientStuff);

        // Register ourselves for server and other game events we are interested in
        MinecraftForge.EVENT_BUS.register(this);
    }
  ...

 

First few lines in Registration.java

@Mod.EventBusSubscriber(modid = nbaddons.MOD_ID, bus = Mod.EventBusSubscriber.Bus.FORGE)
public class Registration {

    public static final DeferredRegister<Block> VANILLA_BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS, "minecraft");

    public static void register() {
        VANILLA_BLOCKS.register(FMLJavaModLoadingContext.get().getModEventBus());
        NBTNoteBlock.register(); // <-- The block class itself. See NBTNoteBlock.java
    ...

 

First few lines in NBTNoteBlock.java

public class NBTNoteBlock extends NoteBlock {

    //public static Block NOTEBLOCK;
    public static final RegistryObject<Block> NOTEBLOCK = Registration.VANILLA_BLOCKS.register(
            "note_block", () -> new NBTNoteBlock(AbstractBlock.Properties.create(Material.WOOD).sound(SoundType.WOOD).hardnessAndResistance(0.8F)));

    public NBTNoteBlock(Properties properties) {
        super(properties);
    }

    public static void register() {}; // <-- register() is called just to initialize the constant NOTEBLOCK, as mentioned in the tutorial I watched.

 

 Still getting the same error.

 

New Registration.java

    public static final DeferredRegister<Block> VANILLA_BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS, "minecraft");
    public static final RegistryObject<Block> NOTEBLOCK = Registration.VANILLA_BLOCKS.register(
            "note_block", () -> new NBTNoteBlock(AbstractBlock.Properties.create(Material.WOOD).sound(SoundType.WOOD).hardnessAndResistance(0.8F)));


    public static void register() {
        VANILLA_BLOCKS.register(FMLJavaModLoadingContext.get().getModEventBus());
    }

You have not shown this class.

Oops... I omitted the class because I thought I would not need it for the discussion. Here is the full Registration.java.

    public static final DeferredRegister<Block> VANILLA_BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS, "minecraft");
    public static RegistryObject<Block> NOTEBLOCK = VANILLA_BLOCKS.register(
            "note_block", () -> new NBTNoteBlock(AbstractBlock.Properties.create(Material.WOOD).sound(SoundType.WOOD).hardnessAndResistance(0.8F)));
    
    public static final DeferredRegister<TileEntityType<?>> TILE_ENTITIES = DeferredRegister.create(ForgeRegistries.TILE_ENTITIES, nbaddons.MOD_ID);
    public static RegistryObject<TileEntityType<?>> NOTEBLOCK_TE = Registration.TILE_ENTITIES.register(
            "note_block", () -> NoteBlockTileEntity.register("note_block", TileEntityType.Builder.create(NoteBlockTileEntity::new, Blocks.NOTE_BLOCK)));
    
    public static void register() {
            VANILLA_BLOCKS.register(FMLJavaModLoadingContext.get().getModEventBus());
            TILE_ENTITIES.register(FMLJavaModLoadingContext.get().getModEventBus());
    }

NoteBlockTileEntity.java:53 (I copied some lines from TileEntityType::register)

    public static  <T extends TileEntity> TileEntityType<T> register(String key, TileEntityType.Builder<T> builder) {
        Type<?> type = Util.attemptDataFix(TypeReferences.BLOCK_ENTITY, key);
        return Registry.register(Registry.BLOCK_ENTITY_TYPE, key, builder.build(type));
    }

Oh yes that was exactly the problem. Spent a little more time on documentation and figured it out. Thank you so much!

 

Code that works.

@Mod.EventBusSubscriber(modid = nbaddons.MOD_ID, bus = Mod.EventBusSubscriber.Bus.FORGE)
public class Registration {
    public static final DeferredRegister<Block> VANILLA_BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS, "minecraft");
    public static RegistryObject<Block> NOTEBLOCK = VANILLA_BLOCKS.register(
            "note_block", () -> new NBTNoteBlock(AbstractBlock.Properties.create(Material.WOOD).sound(SoundType.WOOD).hardnessAndResistance(0.8F)));

    public static final DeferredRegister<TileEntityType<?>> TILE_ENTITIES = DeferredRegister.create(ForgeRegistries.TILE_ENTITIES, nbaddons.MOD_ID);
    public static RegistryObject<TileEntityType<NoteBlockTileEntity>> NOTEBLOCK_TE = TILE_ENTITIES.register(
            "note_block", () -> TileEntityType.Builder.create(NoteBlockTileEntity::new, Blocks.NOTE_BLOCK).build(null));

    public static void register() {
        VANILLA_BLOCKS.register(FMLJavaModLoadingContext.get().getModEventBus());
        TILE_ENTITIES.register(FMLJavaModLoadingContext.get().getModEventBus());
    }
}
