I'm a new modder and just trying to make a simple mod ,but when I put my block ,the game crash with "Registry Object not present".

I've tried to fix it ,but still can't find where wrong.

 

Thanks for helping.

 

crash report :

 

 

conveyor_belt_block.java : 

	@Nullable
	@Override
	public TileEntity createTileEntity(final BlockState state, final IBlockReader world) {
		return ModTileEntityTypes.CONVEYOR_BELT.get().create();  // line38
	}

 

 

ModTileEntityTypes.java :

public final class ModTileEntityTypes {
	
	public static final DeferredRegister<TileEntityType<?>> TILE_ENTITY_TYPES = new DeferredRegister<>(ForgeRegistries.TILE_ENTITIES, Conveyor.modid);
	
	public static final RegistryObject<TileEntityType<conveyor_belt_tile_entity>> CONVEYOR_BELT = TILE_ENTITY_TYPES.register("conveyor_belt", () ->
	TileEntityType.Builder.create(conveyor_belt_tile_entity::new, ModBlocks.CONVEYOR_BELT.get().setRegistryName("conveyor_belt"))
		.build(null)
	);
}

 

 

ModBlocks.java :

public final class ModBlocks {
	public static final DeferredRegister<Block> BLOCKS = new DeferredRegister<>(ForgeRegistries.BLOCKS, Conveyor.modid);
	
	public static final RegistryObject<Block> CONVEYOR_BELT = BLOCKS.register("conveyor_belt", () -> new conveyor_belt_block());

}

 

 

conveyor_belt_tile_entity.java :

public class conveyor_belt_tile_entity extends TileEntity implements ITickableTileEntity{
	
	public conveyor_belt_tile_entity() {
		super(ModTileEntityTypes.CONVEYOR_BELT.get());
	}
	
	@Override
      public void tick() {
      	System.out.println("test tick");
    }
}

Where do you register your DeferredRegister instances to the event bus?

 

Also please follow Java class naming conventions.

 

Sorry, I have already renamed them.

 

Do you mean this?

	@SubscribeEvent
	public static void registerTileEntities (final RegistryEvent.Register<TileEntityType<?>> event) {
			
		ModTileEntityTypes.TILE_ENTITY_TYPES.register(FMLJavaModLoadingContext.get().getModEventBus());
		
		LOGGER.info("TileEntities registered");
	}

 

It doesn't work,the game still crash.

I don't know,registerItems and registerBlocks can work normally.

Is it the correct method to register them?

This is my log.

 

Thanks for your help.

This makes no sense.

The registration to the event bus must happen in your mod class constructor.

When using DeferredRegister you do not subscribe to the events yourself, DeferredRegister handles it all for you.

OK,I'll try it.
Thanks.

It's working !

public Conveyor()
{
	LOGGER.debug("Conveyor mod testing");
		
	final IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus();

	ModBlocks.BLOCKS.register(modEventBus);
	ConveyorItems.ITEMS.register(modEventBus);
	ModTileEntityTypes.TILE_ENTITY_TYPES.register(modEventBus);
		
}
