Hello there. I was just coding my mod and I tried to use `RegistryEvent.Register<Block>` to register my block, but the event doesn't fire.

Other events can be fired though. In my case, `FMLCommonSetupEvent` fired just as normal as it should be.

 

Here is my code:

@Mod(Musician.MOD_ID)
public class Musician {

    public static Musician INSTANCE;
    public static final String MOD_ID = "musician";

    public Musician() {
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        MinecraftForge.EVENT_BUS.register(this);
        INSTANCE = this;
    }

    @SubscribeEvent
    public void setup(final FMLCommonSetupEvent event) {
        LogManager.getLogger().info("Hello from common setup");
    }

    public static final Block NOTE_BLOCK = new MoreNoteBlock().setRegistryName("note_block");

    @SubscribeEvent
    public void registerBlocks(final RegistryEvent.Register<Block> event) {
        event.getRegistry().register(NOTE_BLOCK);
        Item.BLOCK_TO_ITEM.put(NOTE_BLOCK, Blocks.NOTE_BLOCK.asItem());
        LogManager.getLogger().info("Registered Custom Note Block");
    }
}

 

There a few things wrong with code style here. You are trying to execute the registry event on the forge bus and the common setup on both buses. You might want to review events and figure out how to fix this issue.

I took a look at the events and tested them.

 

Method 1 doesn't work:

@Mod(Musician.MOD_ID)
public class Musician {

    public static Musician INSTANCE;
    public static final String MOD_ID = "musician";

    public Musician() {
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        INSTANCE = this;
    }

    @SubscribeEvent
    public void setup(final FMLCommonSetupEvent event) {
        LogManager.getLogger().info("Hello from common setup");
    }
}

@Mod.EventBusSubscriber(modid = Musician.MOD_ID)
class RegistryHandler {
    public static final Block NOTE_BLOCK = new MoreNoteBlock().setRegistryName("note_block");

    @SubscribeEvent
    public static void registerBlocks(final RegistryEvent.Register<Block> event) {
        event.getRegistry().register(NOTE_BLOCK);
        Item.BLOCK_TO_ITEM.put(NOTE_BLOCK, Blocks.NOTE_BLOCK.asItem());
        LogManager.getLogger().info("Registered Custom Note Block");
    }
}

 

So does method 2:

@Mod(Musician.MOD_ID)
public class Musician {

    public static Musician INSTANCE;
    public static final String MOD_ID = "musician";

    public Musician() {
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        MinecraftForge.EVENT_BUS.register(RegistryHandler.class);
        INSTANCE = this;
    }

    @SubscribeEvent
    public void setup(final FMLCommonSetupEvent event) {
        LogManager.getLogger().info("Hello from common setup");
    }
}

class RegistryHandler {
    public static final Block NOTE_BLOCK = new MoreNoteBlock().setRegistryName("note_block");

    @SubscribeEvent
    public static void registerBlocks(final RegistryEvent.Register<Block> event) {
        event.getRegistry().register(NOTE_BLOCK);
        Item.BLOCK_TO_ITEM.put(NOTE_BLOCK, Blocks.NOTE_BLOCK.asItem());
        LogManager.getLogger().info("Registered Custom Note Block");
    }
}

 

Method 3 also:

@Mod(Musician.MOD_ID)
public class Musician {

    public static Musician INSTANCE;
    public static final String MOD_ID = "musician";

    public Musician() {
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        MinecraftForge.EVENT_BUS.register(new RegistryHandler());
        INSTANCE = this;
    }

    @SubscribeEvent
    public void setup(final FMLCommonSetupEvent event) {
        LogManager.getLogger().info("Hello from common setup");
    }
}

class RegistryHandler {
    public static final Block NOTE_BLOCK = new MoreNoteBlock().setRegistryName("note_block");

    @SubscribeEvent
    public void registerBlocks(final RegistryEvent.Register<Block> event) {
        event.getRegistry().register(NOTE_BLOCK);
        Item.BLOCK_TO_ITEM.put(NOTE_BLOCK, Blocks.NOTE_BLOCK.asItem());
        LogManager.getLogger().info("Registered Custom Note Block");
    }
}

The 4th method still doesn't work:

@Mod(Musician.MOD_ID)
public class Musician {

    public static Musician INSTANCE;
    public static final String MOD_ID = "musician";

    public Musician() {
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        MinecraftForge.EVENT_BUS.addListener(this::registerBlocks);
        INSTANCE = this;
    }

    @SubscribeEvent
    public void setup(final FMLCommonSetupEvent event) {
        LogManager.getLogger().info("Hello from common setup");
    }

    public static final Block NOTE_BLOCK = new MoreNoteBlock().setRegistryName("note_block");

    public void registerBlocks(final RegistryEvent.Register<Block> event) {
        event.getRegistry().register(NOTE_BLOCK);
        Item.BLOCK_TO_ITEM.put(NOTE_BLOCK, Blocks.NOTE_BLOCK.asItem());
        LogManager.getLogger().info("Registered Custom Note Block");
    }
}

 

Method 5 also failed:

@Mod(Musician.MOD_ID)
public class Musician {

    public static Musician INSTANCE;
    public static final String MOD_ID = "musician";

    public Musician() {
        FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);
        MinecraftForge.EVENT_BUS.addGenericListener(Block.class, this::registerBlocks);
        INSTANCE = this;
    }

    @SubscribeEvent
    public void setup(final FMLCommonSetupEvent event) {
        LogManager.getLogger().info("Hello from common setup");
    }

    public static final Block NOTE_BLOCK = new MoreNoteBlock().setRegistryName("note_block");

    @SubscribeEvent
    public void registerBlocks(final RegistryEvent.Register<Block> event) {
        event.getRegistry().register(NOTE_BLOCK);
        Item.BLOCK_TO_ITEM.put(NOTE_BLOCK, Blocks.NOTE_BLOCK.asItem());
        LogManager.getLogger().info("Registered Custom Note Block");
    }
}

 

Now I'm really confused.

Method 1: annotation on common setup does nothing, registry event still on forge bus

Method 2: same as method 1

Method 3: same as above

Method 4: crash on startup

Method 5: same as method 1

 

Essentially, you did the same thing over and over. You read the resources but ignored my comment.

Ok I just went back and tried all of them again without the lines

FMLJavaModLoadingContext.get().getModEventBus().addListener(this::setup);

and

@SubscribeEvent
public void setup(final FMLCommonSetupEvent event) {
    LogManager.getLogger().info("Hello from common setup");
}

 

And I still can register my block

Alright, I clearly misunderstood everything.

I just swapped `MinecraftForge.EVENT_BUS` with `FMLJavaModLoadingContext.get().getModEventBus()` and then everything works again.

 

Sorry for being dumb.
