How to register a spawn-egg as item?

Recommended Posts

The first parameter is the EntityType of the entity to spawn. As I've told you in your other thread construct it in this event using the builder, I've even shown you how to do so with an example line.

The last parameter is the parameters of the item(max stack size, it's ItemGroup, container item, etc). Look at how other items are registered in the Item class.

public static EntityType<EntityItem> storedItemType;
    
@SubscribeEvent
public static void onItemRegistry(RegistryEvent.Register<Item> event)
{
    // Here for example I am creating a type for the EntityItem, you would need your own entity here with your own parameters.
    storedItemType = EntityType.Builder.create(EntityItem.class, EntityItem::new).tracker(32, 1, true).build("v0idstestmod.test_entity");
    event.getRegistry().register(new ItemSpawnEgg(storedItemType, 0xffffff, 0x00ff00, new Item.Properties().group(ItemGroup.MISC)));
    // Your other registration code
    ...
}

Oh and i don´t know, what "sendvelocity" in your entity-register-line is for

Whether the server should send the velocity data to the client.

Thet´s ( helper method ) what i need a sample for

 

public static <T extends Entity>EntityType<T> registerEntityAndEgg(IForgeRegistry<Item> itemRegistry, Class<T> entityClass, Function<? super World, T> factory, int eggPrimaryColor, int eggSecondaryColor, int trackingRange, int updateFrequency, boolean sendVelocityUpdates, String name)
    {
        EntityType<T> type = EntityType.Builder.create(entityClass, factory).tracker(trackingRange, updateFrequency, sendVelocityUpdates).build(TestMod.MODID + '.' + name);
        itemRegistry.register(new ItemSpawnEgg(type, eggPrimaryColor, eggSecondaryColor, new Item.Properties().group(ItemGroup.MISC)).setRegistryName(name));
        return type;
    }

Or something along those lines, I am not writing code for you, this is just an example that you will need to adjust to your needs.

@SubscribeEvent
		public static void registerEntities(final RegistryEvent.Register<EntityType> event)
		{
			event.getRegistry().register(EntityType.Builder.create(EntityRed.class, EntityRed::new).tracker(32, 1, true).build("AngryBirdsMod.EntityRed"));
			LOGGER.info("Entities registered.");
		}

EntityType is a valid registry entry, you don't need to change it to anything. Of course it has a generic parameter you must provide, this is basic java. Since this is a forge event a wildcard type will do.

A type parameter is declared within the <>.

Say a List<T> is a generic class where T is the type parameter. When you create a new list you specify said type parameter, like new List<String>. Now String is the type parameter, meaning that List now only accepts strings.

If you want said List to accept anything you declare a wildcard as it's type parameter(new List<?>).
