Is this a valid way to register entities? Be it entities extending classes such as ProjectileItemEntity or MonsterEntity class.

The reason I ask is because while the mob entity is registring and showing in game just fine, the throwable entity is not, and is completely invisible in game when spawned (even when I don't register entity rendering with the RenderingRegistry class - this would in turn render it as a white box which is not happening).

    public static EntityType<?> ENT_MOB = null;
    public static EntityType<EntityModProjectile> ENT_PROJECTILE = null;

        static
        {
			ENT_MOB = registerEntityAndEgg(event.getRegistry(), EntityType.Builder.create(EntityModMob::new, EntityClassification.MONSTER).size(0.6F, 1.95F), 0xdcdcdc, 0xe21a1a, "ent_mob");
			ENT_PROJECTILE = registerEntity(EntityType.Builder.<EntityModProjectile>create(EntityModProjectile::new, EntityClassification.MISC).size(0.25F, 0.25F).setTrackingRange(64).setUpdateInterval(20).setShouldReceiveVelocityUpdates(false), "ent_projectile");
		}

        @SubscribeEvent
        public static void registerItems(final RegistryEvent.Register<EntityType<?>> event)
        {
			event.getRegistry().registerAll(ENT_MOB, ENT_PROJECTILE);
		}

        public static <T extends Entity> EntityType<T> registerEntity(EntityType.Builder builder, String name)
        {
            EntityType<T> type = (EntityType<T>) builder.build(Main.MODID + '.' + name).setRegistryName(name);
            return type;
        }

 

And this is how I register entity rendering:

RenderingRegistry.registerEntityRenderingHandler(EntityModMob.class, renderManager -> new RenderModMob(renderManager));
RenderingRegistry.registerEntityRenderingHandler(EntityModProjectile.class, renderManager -> new SpriteRenderer<EntityModProjectile>(renderManager, Minecraft.getInstance().getItemRenderer()));

 

EntityModProjectile class:

public class EntityModProjectile extends ProjectileItemEntity
{
    public EntityModProjectile(EntityType<? extends EntityModProjectile> entityTypeIn, World worldIn)
    {
        super(entityTypeIn, worldIn);
    }

    public EntityModProjectile(World worldIn, LivingEntity throwerIn)
    {
        super(ModEntityType.ENT_PROJECTILE, throwerIn, worldIn);
    }

    public EntityModProjectile(World worldIn, double x, double y, double z)
    {
        super(ModEntityType.ENT_PROJECTILE, x, y, z, worldIn);
    }

    @Override
    protected Item func_213885_i()
    {
        return ModItems.MOD_PROJECTILE;
    }
}

You need to avoid putting static fields in your registry events.

Build the EntityTypes in the RegisterAll parameter list.

 

If you need to cross-reference between your EntityTypes and renderers, use ObjectHolders 

 

Here's a snippet from my [simple] mod where create my Events for 1 block (and its BlockItem), 1 Item and a custom [Mob] Entity

    //Mod Event bus for receiving Registry Events)
    @Mod.EventBusSubscriber(modid=ChickenMod.MODID, bus=Mod.EventBusSubscriber.Bus.MOD)
    @ObjectHolder(ChickenMod.MODID)
    public static class RegistryEvents {
    	
    	public static final Block test_block=null;
    	public static final Item test_item=null;
    	public static final EntityType<EntityProtoChicken> protochicken=null;
    	
        @SubscribeEvent
        public static void onBlocksRegistry(final RegistryEvent.Register<Block> blockRegistryEvent) {
    			blockRegistryEvent.getRegistry().registerAll(
    					new Block(Block.Properties.create(Material.IRON)).setRegistryName(ChickenMod.MODID,"test_block")); 
        }
        
        @SubscribeEvent
        public static void onItemsRegistry(final RegistryEvent.Register<Item> itemRegistryEvent) {
        	itemRegistryEvent.getRegistry().registerAll(
        			(Item)new BlockItem(test_block,new Item.Properties().group(ITEMTAB)).setRegistryName(test_block.getRegistryName()),
        			new Item(new Item.Properties().group(ITEMTAB)).setRegistryName(ChickenMod.MODID,"test_item")
        			);
        }
        
    	//Register Entities
    	@SubscribeEvent
    	public static void onEntitiesRegistry(final RegistryEvent.Register<EntityType<?>> entityRegistryEvent) {	
    		entityRegistryEvent.getRegistry().registerAll(		    	
    		    EntityType.Builder.create(EntityProtoChicken::new,EntityClassification.MISC)
    		    	.setShouldReceiveVelocityUpdates(true).setTrackingRange(24).setUpdateInterval(60)
    		    	.build("protochicken").setRegistryName(MODID, "protochicken")
    			);	
    	}

 

...and this is where I register the renderer:

    private void doClientStuff(final FMLClientSetupEvent event) {
        // do something that can only be done on the client
                RenderingRegistry.registerEntityRenderingHandler(EntityProtoChicken.class,RenderProtoChicken :: new);
    }

 

YMMV

Thank you for your input PhilipChonacky.

I've done exactly as you've suggested, but the issue still persists, the entity I'm summoning with the /summon command is still invisible.

 

It says the entity has been registered in the console, so I'm not quite sure what could be the problem.

Keep in mind that this only occurs with entities that are created with SSpawnObjectPacket and not SSpawnMobPacket in the IPacket<?> createSpawnPacket() method it seems, because mob entities register and render just fine in-game, as previously stated.

I think something may be missing in the forge registry/spawn code. I have an entity that is mountable and I get a [minecraft/ClientPlayNetHandler]: Received passengers for unknown entity warning in the console. The entity is not visible and cannot be controlled. So you're not the only one experiencing this type of issue. 

I'm having exactly the same problem now. My Mobs are showing up great but my projectiles do not show up on the client at all, anything spawned via SSpawnMobPacket is great but SSpawnObjectPacket is not showing.

I use an EntityFactory object rather than the entity constructors and that also isn't being called by SSpawnObjectPacket on the client.

I solved it. Here's how I did it:

 

When I set the EntityType variable for my named variable "ENT_PROJECTILE" and build, I use the setCustomClientFactory method, so it would look exactly like this:

ENT_PROJECTILE = registerEntity(EntityType.Builder.<EntityModProjectile>create(EntityClassification.MISC).setCustomClientFactory(EntityModProjectile::new).size(0.25F, 0.25F), "ent_projectile");

 

Inside of my EntityModProjectile class I extended the ProjectileItemEntity class, overrided the createSpawnPacket method and returned getEntitySpawningPacket from NetworkHooks class. Like this:

    @Override
    public IPacket<?> createSpawnPacket()
    {
        return NetworkHooks.getEntitySpawningPacket(this);
    }

 

I then created another constructor inside of the EntityModProjectile class, like this:

    public EntityModProjectile(FMLPlayMessages.SpawnEntity packet, World worldIn)
    {
        super(ModEntityType.ENT_PROJECTILE, worldIn);
    }

 

Thanks! Now my parachute spawns and I can mount it. I can't control it though, still working on that.
