I recently got back into modding and I've encountered the classic white box entity rendering problem when trying to make an ender-pearl-like item. I've done a lot of googling, and I feel pretty confident in my code, but it still doesn't work for some reason.

 

Here's the relevant code (that is, no other code involves rendering this particular entity)

 

ExampleMod#init

@EventHandler
    public void init(FMLInitializationEvent event)
    {
    	proxy.registerRenderItems();
proxy.registerRenderEntities();
    }

^{Yes, I have all of the @SidedProxy stuff and I know it works}

 

ClientProxy

public class ClientProxy extends CommonProxy{

@Override
public void registerRenderItems(){
	ItemModelMesher renderer = Minecraft.getMinecraft().getRenderItem().getItemModelMesher();

	renderer.register(ModItems.flashPearl, 0, new ModelResourceLocation(ModItems.flashPearl.getRegistryName(), "inventory"));
}

@Override
public void registerRenderEntities(){		
	RenderingRegistry.registerEntityRenderingHandler(EntityFlashPearl.class, ((rm) -> new RenderSnowball(rm, ModItems.flashPearl, Minecraft.getMinecraft().getRenderItem())));
}
}

RenderingRegistry.registerEntityRenderingHandler(Class<T>, IRenderFactory<? super T>)

must be called in preInit, as the doc comment says.

 

Item models should be registered with

ModelLoader.setCustomModelResourceLocation

/

setCustomMeshDefinition

in

ModelRegistryEvent

(if you're registering your

Item

s using the new registry events, which you should be) or preInit (if you're registering your

Item

s in preInit).

I did something similar to your example on that thread you linked...

public class ModItems {
public static Item FLASH_PEARL = new ItemFlashPearl().setUnlocalizedName("flash_pearl").setRegistryName("flash_pearl");

@Mod.EventBusSubscriber
public static class RegistrationHandler {
	public static final Set<Item> ITEMS = new HashSet<>();

	@SubscribeEvent
	public static void registerItems(RegistryEvent.Register<Item> event) {
		final IForgeRegistry<Item> registry = event.getRegistry();

		registry.registerAll(
				FLASH_PEARL
		);
	}
}

 

...but the event never seems to be called (and I couldn't find anything else that I needed to add in your example mod) so the game just crashes when it tries to register a renderer for a non-existent item. I don't have much experience with forge events so I apologize for my ignorance here.

You also need to register it using MinecraftForge..register() in preInit

No, that is not possible.

RegistryEvent

is fired before

preInit

.

You need to use the

@Mod.EventBusSubscriber

annotation to register it.

So it turns out the CTD I was encountering was actually completely unrelated to the item registering (I changed other code as well so I assumed it was an issue with item registering).

 

The thing from my previous post works fine and fixes the problem. For other modders who come across this, don't use any GameRegistry.register stuff for registering items and just use RegistryEvent.Register<Item>.

i never had any issues with GameRegistry.register except for the fact that if a block is null and you try to register an Item for the block (ItemBlock) to a block that's null it will crash. That's why I always defnie and register  all my blocks first then my items second.
