Hello! I've been porting my mod to 1.12 and I'm having issues with the new registry system. Did I do something wrong below?

 

public final class IvBlocks {
	
	@GameRegistry.ObjectHolder("iv:light_blue_stairs")
	public static LightBlueStairs light_blue_stairs;
	
	@SubscribeEvent
    public static void registerBlocks(RegistryEvent.Register<Block> event) {
        event.getRegistry().register(new LightBlueStairs());
    }
	
    @SubscribeEvent
    public static void registerItems(RegistryEvent.Register<Item> event) {
        event.getRegistry().register(new ItemBlock(light_blue_stairs).setRegistryName(light_blue_stairs.getRegistryName()));
    }
}

     

public class LightBlueStairs extends BlockStairs{
	public LightBlueStairs() {
		super(Blocks.STAINED_HARDENED_CLAY.getStateFromMeta(3));
	    this.setCreativeTab(CreativeTabs.MATERIALS);
	    setUnlocalizedName("light_blue_stairs");
	    setRegistryName(Reference.MOD_ID + ":" + "light_blue_stairs"); 

	}
}

public class CommonProxy {

	@EventHandler
    public void preInit(FMLPreInitializationEvent e) {
		MinecraftForge.EVENT_BUS.register(new IvBlocks());
	}
	@EventHandler
    public void init(FMLInitializationEvent e) {
		
	}
    @EventHandler
    public void postInit(FMLPostInitializationEvent e) {

    }
}

 

I think this line might cause trouble because you're setting the registry name from getting the registry name: 

        event.getRegistry().register(new ItemBlock(light_blue_stairs).setRegistryName(light_blue_stairs.getRegistryName()));

Also, I think that uou need to register the item model mesher in your client proxy.

 

But you didn't really say what is going wrong -- is it not showing up at all? is it showing up but with the wrong model or texture?

OP is setting the registry name of an ItemBlock and is getting the name from a Block. That is a perfectly fine way to do it.

 

@OrangeVillager61 your methods that handle the events are static yet you are using an instance-based bus subscribing. If you are using Mod.EventBusSubscriber then the handler methods must be static, if you are using EventBus::register then they can't be static. Forge's documentation explains it here.

The field you annotate with ObjectHolder must have the following signature and declaration:

public static final TYPE NAME = null; You are missing the final modifier.

 

Additionally there is no reason to declare a class that only contains static methods final. A final modifier on a class means that other classes can't extend from it.

Also no. ModelLoader is correct. 

Also instead of

setUnlocalizedName("light_blue_stairs");
setRegistryName(Reference.MOD_ID + ":" + "light_blue_stairs"); 

you should do something more like

setRegistryName("light_blue_stairs");
setUnlocalizedName(getRegistryName.toString());

So like this?

 

@Mod.EventBusSubscriber
public final class IvBlocks {

	@GameRegistry.ObjectHolder("iv:light_blue_stairs")
	public static LightBlueStairs light_blue_stairs = null;
	
	@SubscribeEvent
    public static void registerBlocks(RegistryEvent.Register<Block> event) {
        event.getRegistry().register(new LightBlueStairs());
    }
	
    @SubscribeEvent
    public static void registerItems(RegistryEvent.Register<Item> event) {
        event.getRegistry().register(new ItemBlock(light_blue_stairs).setRegistryName(light_blue_stairs.getRegistryName()));
    }
}

 

Looks mostly correct, yes.

I removed the null and replaced it with new LightBlueStairs, is that okay since the null was crashing MC. Also, where do I register the models?

You were still missing the final modifier on the field. If you are manually setting the field to something else than null then you are not using ObjectHolders correctly, or at all for that matter.

In a ModelRegistryEvent handler.

In a ModelRegistryEvent handler.

@Mod.EventBusSubscriber
public final class IvBlocks {

	@GameRegistry.ObjectHolder("iv:light_blue_stairs")
	public static final LightBlueStairs light_blue_stairs = null;
	
	@SubscribeEvent
    public static void registerBlocks(RegistryEvent.Register<Block> event) {
        event.getRegistry().register(new LightBlueStairs());
    }
	
    @SubscribeEvent
    public static void registerItems(RegistryEvent.Register<Item> event) {
        event.getRegistry().register(new ItemBlock(light_blue_stairs).setRegistryName(light_blue_stairs.getRegistryName()));
    }
}

This is my current code and it crashes at null.

That should not be happening. Are you sure that the LightBlueStairs constructor sets the registry name of the block to "iv:light_blue_stairs"? Is there anything in the log(fml-*****-latest, not the log you see in your ide's output window) mentioning the ObjectHolder? If forge can't inject an object into a field annotated with ObjectHolder it will log a message.

I didn't see anything about ObjectHolders but I did see this in the log:

 

[10:42:14] [main/DEBUG] [FML/]: Unable to lookup iv:light_blue_stairs for public static orangeVillager61.configVillagerPerDoor.Blocks.LightBlueStairs orangeVillager61.configVillagerPerDoor.Blocks.IvBlocks.light_blue_stairs. This means the object wasn't registered. It's likely just mod options.

 

That message means that forge was unable to find an object with that registry name in a registry.

Additionally you could try to change the type of the field from LightBlueStairs to Block. I am pretty sure that forge still figures out that your type is a subclass of Block and the registry for blocks is the one to search through though.

Okay, I'll try that.

 

Oh, nvm. I've been using the wrong mod_id.

Fixing the mod_id fixed most of it but the block doesn't have a texture in the inventory.

 

@Mod.EventBusSubscriber
public final class IvBlocks {

	@GameRegistry.ObjectHolder("cs:light_blue_stairs")
	public static final LightBlueStairs light_blue_stairs = null;
	
	@SubscribeEvent
    public static void registerBlocks(RegistryEvent.Register<Block> event) {
        event.getRegistry().register(new LightBlueStairs());
    }
	
    @SubscribeEvent
    public static void registerItems(RegistryEvent.Register<Item> event) {
        event.getRegistry().register(new ItemBlock(light_blue_stairs).setRegistryName(light_blue_stairs.getRegistryName()));
    }
    
    @SideOnly(Side.CLIENT)
    public static void initModels() {
    	light_blue_stairs.initModel();
    }
}
public class LightBlueStairs extends BlockStairs{
	public LightBlueStairs() {
		super(Blocks.STAINED_HARDENED_CLAY.getStateFromMeta(3));
	    this.setCreativeTab(CreativeTabs.MATERIALS);
	    setRegistryName("light_blue_stairs");
	    setUnlocalizedName(Reference.MOD_ID + ":" + "light_blue_stairs");

	}

    @SideOnly(Side.CLIENT)
    public void initModel() {
        ModelLoader.setCustomModelResourceLocation(Item.getItemFromBlock(this), 0, new ModelResourceLocation(getRegistryName(), "inventory"));
    }
}

 

Show your ModelRegistryEvent hander then. 

Annotating methods with SideOnly is not a very good way of doing anything, really. SideOnly is too unreliable. Proxies exist for a reason.

public class ClientProxy extends CommonProxy{
    
	 @Override
	    public void preInit(FMLPreInitializationEvent e) {
	        super.preInit(e);
	        
			MinecraftForge.EVENT_BUS.register(new RegisterModels());
	    }

	 @Override
	    public void init(FMLInitializationEvent e) {
	        super.init(e);
	    }

	    @Override
	    public void postInit(FMLPostInitializationEvent e) {
	        super.postInit(e);
	    }
}
public class RegisterModels {
	
    @SubscribeEvent
    public static void registerModels(ModelRegistryEvent event) {
        IvBlocks.initModels();
    }
}

I fear that the issue is with my client proxy.

Also I don't think that having more than 1 different non-nested public(aka top-level) class within 1 java file is even valid java. Or is this just the way you've formatted your post and not your actual code snippet?

That's just how I posted it, not my actual files.

Alright, that fixed the issue. Thanks for the help!
