[1.15.2] Trouble adding Entities to the game

[Triphion]

I've managed to add entities to the mod, but not with spawn eggs and natural spawns. To start off with, I don't know when to add the entity spawns. Secondly, I don't know if my current spawn code actually works since I haven't tried it, but if you see some problem with it, please point that out. And lastly, the spawn eggs. I know how to add a spawn egg, unfortunately, since i'm using deferred registries for the entities etc. the normal "Entitytype.MYENTITY" does not work, and neither does "Entitytype.MYENTITY.get()" nor "RegistryObject.of(Entitytype.MYENTITY.getId(), ForgeRegistries.ENTITIES)". So to fix this, i decided to pretty much copy the original spawnEggItem class, and change it so it can work with deferred registries. But, some problem has arisen there as well. Specifically, the coloring of the egg; it's always white and grey. 

 

 

 

	public static void registerSpawns() 
	{
		spawnEntities(RegistryObject.of(EtauricEntities.CHUPNUT.getId(), ForgeRegistries.ENTITIES), 25, 1, 3, Biome.Category.FOREST);
		spawnEntities(RegistryObject.of(EntityType.IRON_GOLEM.getRegistryName(), ForgeRegistries.ENTITIES), 25, 1, 3, Biome.Category.FOREST);
	}
	
	private static void spawnEntities(RegistryObject<? extends EntityType<? extends LivingEntity>> entityType, int weightIn, int minGroupCountIn, int maxGroupCountIn, Biome.Category...biomes) 
	{
		Utils.getLogger().info("EntityType: " + entityType);
		
		for (int i = 0; i < biomes.length; i++)
		{
			for (Biome biome : ForgeRegistries.BIOMES)
			{
				if (biome.getCategory() == biomes[i])
				{
					biome.getSpawns(EntityClassification.MONSTER).add(new Biome.SpawnListEntry(entityType.get(), weightIn, minGroupCountIn, maxGroupCountIn));
				}
			}
		}
	}

This is my entity spawn method. 

 

public class EtauricSpawnEggItem extends Item
{
	private static final Map<RegistryObject<? extends EntityType<?>>, EtauricSpawnEggItem> EGGS = Maps.newIdentityHashMap();
	private final int primaryColor;
	private final int secondaryColor;
	private final RegistryObject<? extends EntityType<?>> typeIn;
	
	public EtauricSpawnEggItem(RegistryObject<? extends EntityType<?>> typeIn, int primaryColorIn, int secondaryColorIn, Properties builder) 
	{
		super(builder);
		this.typeIn = typeIn;
		this.primaryColor = primaryColorIn;
		this.secondaryColor = secondaryColorIn;
		EGGS.put(typeIn, this);
	}
	
	public ActionResultType onItemUse(ItemUseContext context) 
	{
		World world = context.getWorld();
		if (world.isRemote) 
		{
			return ActionResultType.SUCCESS;
		} 
		else 
		{
			ItemStack itemstack = context.getItem();
			BlockPos blockpos = context.getPos();
			Direction direction = context.getFace();
			BlockState blockstate = world.getBlockState(blockpos);
			Block block = blockstate.getBlock();
			if (block == Blocks.SPAWNER) 
			{
				TileEntity tileentity = world.getTileEntity(blockpos);
				if (tileentity instanceof MobSpawnerTileEntity) 
				{
					AbstractSpawner abstractspawner = ((MobSpawnerTileEntity)tileentity).getSpawnerBaseLogic();
					RegistryObject<? extends EntityType<?>> entitytype1 = this.getType(itemstack.getTag());
					abstractspawner.setEntityType(entitytype1.get());
					tileentity.markDirty();
					world.notifyBlockUpdate(blockpos, blockstate, blockstate, 3);
					itemstack.shrink(1);
					return ActionResultType.SUCCESS;
				}
			}

			BlockPos blockpos1;
			if (blockstate.getCollisionShape(world, blockpos).isEmpty()) 
			{
				blockpos1 = blockpos;
			} 
			else 
			{
				blockpos1 = blockpos.offset(direction);
		    }
			RegistryObject<? extends EntityType<?>> entitytype = this.getType(itemstack.getTag());
			if (entitytype.get().spawn(world, itemstack, context.getPlayer(), blockpos1, SpawnReason.SPAWN_EGG, true, !Objects.equals(blockpos, blockpos1) && direction == Direction.UP) != null) 
			{
				itemstack.shrink(1);
		    }

			return ActionResultType.SUCCESS;
		}
	}

		   /**
		    * Called to trigger the item's "innate" right click behavior. To handle when this item is used on a Block, see
		    * {@link #onItemUse}.
		    */
	public ActionResult<ItemStack> onItemRightClick(World worldIn, PlayerEntity playerIn, Hand handIn) 
	{
		ItemStack itemstack = playerIn.getHeldItem(handIn);
		RayTraceResult raytraceresult = rayTrace(worldIn, playerIn, RayTraceContext.FluidMode.SOURCE_ONLY);
		if (raytraceresult.getType() != RayTraceResult.Type.BLOCK) 
		{
			return ActionResult.resultPass(itemstack);
		} 
		else if (worldIn.isRemote) 
		{
			return ActionResult.resultSuccess(itemstack);
		} 
		else 
		{
			BlockRayTraceResult blockraytraceresult = (BlockRayTraceResult)raytraceresult;
			BlockPos blockpos = blockraytraceresult.getPos();
			if (!(worldIn.getBlockState(blockpos).getBlock() instanceof FlowingFluidBlock)) 
			{
				return ActionResult.resultPass(itemstack);
			} 
			else if (worldIn.isBlockModifiable(playerIn, blockpos) && playerIn.canPlayerEdit(blockpos, blockraytraceresult.getFace(), itemstack)) 
			{
				RegistryObject<? extends EntityType<?>> entitytype = this.getType(itemstack.getTag());
				if (entitytype.get().spawn(worldIn, itemstack, playerIn, blockpos, SpawnReason.SPAWN_EGG, false, false) == null) 
				{
					return ActionResult.resultPass(itemstack);
				} 
				else 
				{
					if (!playerIn.abilities.isCreativeMode) 
					{
						itemstack.shrink(1);
					}
					playerIn.addStat(Stats.ITEM_USED.get(this));
					return ActionResult.resultSuccess(itemstack);
				}
			} 
			else 
			{
				return ActionResult.resultFail(itemstack);
			}
		}
	}

	public boolean hasType(@Nullable CompoundNBT p_208077_1_, RegistryObject<? extends EntityType<?>> type) 
	{
		return Objects.equals(this.getType(p_208077_1_), type);
	}

	@OnlyIn(Dist.CLIENT)
	public int getColor(int tintIndex) 
	{
		return tintIndex == 0 ? this.primaryColor : this.secondaryColor;
	}

	@Nullable
	@OnlyIn(Dist.CLIENT)
	public static EtauricSpawnEggItem getEgg(@Nullable RegistryObject<? extends EntityType<?>> type) 
	{
		return EGGS.get(type);
	}

	public static Iterable<EtauricSpawnEggItem> getEggs() 
	{
		return Iterables.unmodifiableIterable(EGGS.values());
	}

	public RegistryObject<? extends EntityType<?>> getType(@Nullable CompoundNBT p_208076_1_) 
	{
		if (p_208076_1_ != null && p_208076_1_.contains("EntityTag", 10)) 
		{
			CompoundNBT compoundnbt = p_208076_1_.getCompound("EntityTag");
			if (compoundnbt.contains("id", 8)) 
			{
				return RegistryObject.of(new ResourceLocation(compoundnbt.getString("id")), ForgeRegistries.ENTITIES);
			}
		}
		return this.typeIn;
	}
}

This is my spawn egg class. 

 

	public static final RegistryObject<Item> CHUPNUT_SPAWN_EGG = ITEMS.register("chupnut_spawn_egg", () -> new EtauricSpawnEggItem(RegistryObject.of(EtauricEntities.CHUPNUT.getId(), ForgeRegistries.ENTITIES), 4993583, 12692382, (new Item.Properties().group(ItemGroup.MISC))));

And this is how I register it in my Items register. 

 

Any sort of help is very much appreciated.
