I tried spawning my entity, but it did not work and I got this error:

I don't understand much of what it says, but if I read it correctly there should be a problem when rendering my entity. Here is the code: 

package mod.dragonita.fantasymod.client.renders;

import mod.dragonita.fantasymod.Main;
import mod.dragonita.fantasymod.client.models.UnicornEntityModel;
import mod.dragonita.fantasymod.entities.UnicornEntity;
import net.minecraft.client.renderer.entity.EntityRenderer;
import net.minecraft.client.renderer.entity.EntityRendererManager;
import net.minecraft.client.renderer.entity.MobRenderer;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.fml.client.registry.IRenderFactory;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber;

@EventBusSubscriber(modid = Main.MODID, bus = EventBusSubscriber.Bus.MOD, value = Dist.CLIENT)

public class UnicornEntityRender extends MobRenderer<UnicornEntity, UnicornEntityModel>
{	
	public UnicornEntityRender(EntityRendererManager manager)
	{
		super(manager, new UnicornEntityModel(), 0f);
	}

	public static final ResourceLocation unicorn = new ResourceLocation("fantasymod:textures/entity/unicorn_entity.png");
	
	public static class RenderFactory implements IRenderFactory<UnicornEntity>
	{

		@Override
		public EntityRenderer<? super UnicornEntity> createRenderFor(EntityRendererManager manager)
		{
			return new UnicornEntityRender(manager);
		}
		
	}

	@Override
	public ResourceLocation getEntityTexture(UnicornEntity entity) {
		return unicorn;
	}
}

 

 

So I register them: 

package mod.dragonita.fantasymod.client.renders;

import mod.dragonita.fantasymod.Main;
import mod.dragonita.fantasymod.init.ModEntityTypes;
import net.minecraftforge.api.distmarker.Dist;
import net.minecraftforge.fml.client.registry.RenderingRegistry;
import net.minecraftforge.fml.common.Mod.EventBusSubscriber;

@EventBusSubscriber(modid = Main.MODID, bus = EventBusSubscriber.Bus.MOD, value = Dist.CLIENT)
public class FantasyRenderRegistry
{
	
	public void registryEntityRenders()
	{
		RenderingRegistry.registerEntityRenderingHandler(ModEntityTypes.UNICORN, new UnicornEntityRender.RenderFactory());
	}
}

 

And here is how I register my SpawnEgg, but there I have to post all the code, here:

						});
		
		LOGGER.debug("Registered Items");
	}
	
	@SubscribeEvent
	public static void onRegisterTileEntityTypes(@Nonnull final RegistryEvent.Register<TileEntityType<?>> event) {

		// Register your TileEntityTypes here if you have them

		event.getRegistry().registerAll(

				// We don't have a datafixer for our TileEntity, so we pass null into build

		);

		LOGGER.debug("Registered TileEntityTypes");

	}
	
	
	//@SubscribeEvent

	//}

	
	/**

		return entry;

	}
}

 

 

But as it is unreadable I will show the parts that are really important: 

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

			setup(new SpawnEggItem(ModEntityTypes.UNICORN, 0xf0f0f0, 0xdf51f5, new Item.Properties().group(ModItemGroups.RAINBOW_MOD_GROUP)), "unicorn_entity_egg")
		);
		
        	@Nonnull

	private static <T extends IForgeRegistryEntry<T>> T setup(@Nonnull final T entry, @Nonnull final String name) {

		Preconditions.checkNotNull(name, "Name to assign to entry cannot be null!");

		return setup(entry, new ResourceLocation(Main.MODID, name));

	}



	/**

	 * Performs setup on a registry entry

	 *

	 * @param registryName The full registry name of the entry

	 */

	@Nonnull

	private static <T extends IForgeRegistryEntry<T>> T setup(@Nonnull final T entry, @Nonnull final ResourceLocation registryName) {

		Preconditions.checkNotNull(entry, "Entry cannot be null!");

		Preconditions.checkNotNull(registryName, "Registry name to assign to entry cannot be null!");

		entry.setRegistryName(registryName);

		return entry;

	}
		LOGGER.debug("Registered Items");
	}

 

If anyone is wondering how to register my EntityType, this is what I do: 

package mod.dragonita.fantasymod.init;

import mod.dragonita.fantasymod.entities.UnicornEntity;
import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityClassification;
import net.minecraft.entity.EntityType;
import net.minecraft.util.registry.Registry;

public class ModEntityTypes extends net.minecraftforge.registries.ForgeRegistryEntry<EntityType<?>>{
	public static EntityType<UnicornEntity> UNICORN = register("unicorn_entity", EntityType.Builder.create(UnicornEntity::new, EntityClassification.CREATURE));

	@SuppressWarnings("deprecation")
	private static <T extends Entity> EntityType<T> register(String key, EntityType.Builder<T> builder) {
		return Registry.register(Registry.ENTITY_TYPE, key, builder.build(key));
	}
}

 

 

If it has something to do with my EntityModel, dqnn I have to sqgen dqss I first wanted to see if my code would work, and then add it to my Custom EntityModel, for that I tried the Vanilla Bat Model first, but I would be surprised if that was the problem, but here is the model (I just adapted it a bit):

		        this.batLeftWing.rotateAngleY = -this.batRightWing.rotateAngleY;
		        this.batOuterLeftWing.rotateAngleY = -this.batOuterRightWing.rotateAngleY;
	}
}

 

If it is my entity class that is the cause of the problem, then here it is: 

package mod.dragonita.fantasymod.entities;

import net.minecraft.entity.EntityType;
import net.minecraft.entity.SharedMonsterAttributes;
import net.minecraft.entity.ai.goal.LookAtGoal;
import net.minecraft.entity.ai.goal.LookRandomlyGoal;
import net.minecraft.entity.ai.goal.PanicGoal;
import net.minecraft.entity.ai.goal.WaterAvoidingRandomWalkingGoal;
import net.minecraft.entity.passive.horse.HorseEntity;
import net.minecraft.entity.player.PlayerEntity;
import net.minecraft.util.Hand;
import net.minecraft.world.World;

public class UnicornEntity extends HorseEntity{
	
	public UnicornEntity(EntityType<? extends UnicornEntity> type, World worldIn) {
		super(type, worldIn);
	}

	protected void registerGoals()
	{
		this.goalSelector.addGoal(1, new PanicGoal(this, 1.2D));
		this.goalSelector.addGoal(6, new WaterAvoidingRandomWalkingGoal(this, 0.7D));
		this.goalSelector.addGoal(7, new LookAtGoal(this, PlayerEntity.class, 6.0F));
		this.goalSelector.addGoal(8, new LookRandomlyGoal(this));
	}
	
	protected void registerAttributes()
	{
		super.registerAttributes();
		this.getAttribute(SharedMonsterAttributes.MAX_HEALTH).setBaseValue(10.0d);
		this.getAttribute(SharedMonsterAttributes.MOVEMENT_SPEED).setBaseValue(5.0d);
	}
	
	@Override
	public boolean processInteract(PlayerEntity player, Hand hand) {
		return super.processInteract(player, hand);
	}
}

 

 

So, but really, I can't give more information than that, thanks for any help I get.

I read somewhere on here (I'll try to find the post) that you need to create (not register) your EntityType during Item registration, because Items register before EntityTypes, so if you create the EntityType during its registration, when the Item tries to register (before the EntityType), the resulting EntityType passed to the spawn egg is null.

This dont work, I don't know if it's my fault or if I just can't do it. i tried to register it in the same time, but i have got a error, then i tried to register the EntityType before the Item, but it still dont work and if i try to spawn the entity, then the game crashes out and write: 

Description: Unexpected error

But thanks for the Link

I've tried it too, I have to say that (certainly in an unclear way), but I don't know if I'm doing it wrong or anything else, but it crashes the game.

Here is my Code:

 

Here I created my entity types: 

package mod.dragonita.fantasymod.init;

@ObjectHolder(Main.MODID)
public class ModEntityTypes{

			.create(UnicornEntity::new, EntityClassification.CREATURE)
			.size(5F, 7F)
			.build("unicorn_entity");

Do not create your registerable stuff with static initializers. Honestly not 100% sure the reasoning, but everyone that knows what they're doing on here says not to, so I'm sure it's a good reason! You want to build/create your EntityType in the Item registration event, like I had previously said. DO NOT register it. Just create it, and assign it to ModEntityTypes.UNICORN.

 

Then after it has been created, you can create/register your spawn egg within the Item registration event.

 

Then register (no need to build/create) your UNICORN in the EntityType registration event, since it has already been created.

 

If you get a crash after this, post updated code, as well as the crash report. Don't assume the crash report is the same as your original post. Also, please use spoiler tags or an external site (github gist, pastebin, etc) to post your logs so it's not a mile of scrolling to get to the bottom :)

What: Not using static initialisers.
Why: Using static initialisers does not allow you to control when your objects are created or the order in which your objects are created.
Consequences: Using static initialisers prevents other mods from overriding your objects, prevents forge from being able to dynamically load/unload mods and can cause weird, unreproducible crashes.
How: Use the @ObjectHolder annotation if you need static references to your objects and create & register your objects in the appropriate registry event. (Note: before registry events Modders created and registered their items in preInit. This practice became out of date in 1.7 with the introduction of registry events, and is no longer possible in 1.13).


If you have a creative tab that uses an item for its icon & that item references that creative tab in its constructor, and both use static initialisers, they both depend on the other being loaded first to function properly. So whichever one actually gets loaded first will cause the other one to get loaded & the other one will use a null reference to the initial one. Since you don’t control the order in which classes are initialised this means that either the item or the creative tab will have a null creative tab/icon and you don’t know which it will be. This causes hard to track down bugs (if you don’t know about this behaviour as it will compile fine).

Related: (trying to find SO article about how 3 classes that depend on eachother for a value will have the runtime value depend on the order in which they are loaded, will edit this to add the article if I find it)

Given what you said, I tried to change using the DeferredRegister, but I got this error, I think it's coming from my entity type, but I don't know why. The Log: Github Link.

Since you already have a github, you should post your code there. Much easier to read on there than pasted here, and as long as you keep updating it, no need to post updated code here.

Making a guess based on the crash without seeing code, you're trying to register something that has not been initialized, so it's trying to register something that is null.

 

*edit: Pretty sure it's an item, since the crash looks to be coming from ModItems.

You set up the repository one folder too low. It needs to be in your project folder, the one above your src folder.

Any reason you have both ModEntityTypes and FantasyModEntities?

I would guess that your EntityType doesn't exist when you try to use it, however, since you haven't set up your repo correctly I can't clone it and debug it locally (Technically I still can but I would have to use my own configuration files (build.gradle, gradle.properties etc.) which you may have customised, so I may not get the same results as you)

      REVIEW OF THE BEST BITCOIN RECOVERY TEAM - MUYERN TRUST HACKER

      By andreygagloev · Posted

      When I first heard about Bitcoin back in 2018, I was skeptical. The idea of a decentralized, digital currency seemed too good to be true. But I was intrigued as I learned more about the technology behind it and its potential. I started small, investing just a few hundred dollars, dipping my toes into the cryptocurrency waters. At first, it was exhilarating to watch the value of my investment grow exponentially. I felt like I was part of the future, an early adopter of this revolutionary new asset. But that euphoria was short-lived. One day, I logged into my digital wallet only to find it empty - my Bitcoin had vanished without a trace. It turned out that the online exchange I had trusted had been hacked, and my funds were stolen. I was devastated, both financially and emotionally. All the potential I had seen in Bitcoin was tainted by the harsh reality that with decentralization came a lack of regulation and oversight. My hard-earned money was gone, lost to the ether of the digital world. This experience taught me a painful lesson about the price of trust in the uncharted territory of cryptocurrency. While the technology holds incredible promise, the risks can be catastrophic if you don't approach it with extreme caution. My Bitcoin investment gamble had failed, and I was left to pick up the pieces, wiser but poorer for having placed my faith in the wrong hands. My sincere appreciation goes to MUYERN TRUST HACKER. You are my hero in recovering my lost funds. Send a direct m a i l ( muyerntrusted ( @ ) mail-me ( . )c o m ) or message on whats app : + 1 ( 4-4-0 ) ( 3 -3 -5 ) ( 0-2-0-5 )

      corail tombstone fire crash

      By Ugdhar · Posted

      You could try posting a log (if there is no log at all, it may be the launcher you are using, the FAQ may have info on how to enable the log) as described in the FAQ, however this will probably need to be reported to/remedied by the mod author.

      corail tombstone fire crash

      By belzabel · Posted

      So me and a couple of friends are playing with a shitpost mod pack and one of the mods in the pack is corail tombstone and for some reason there is a problem with it, where on death to fire the player will get kicked out of the server and the tombstone will not spawn basically deleting an entire inventory, it doesn't matter what type of fire it is, whether it's from vanilla fire/lava, or from modded fire like ice&fire/lycanites and it's common enough to where everyone on the server has experienced at least once or twice and it doesn't give any crash log. a solution to this would be much appreciated thank you!
