I have created and registered an entity type. How can I give this entity type an associated spawn egg item?

This example has been created with Minecraft 1.20.1 in mind. Please reply if you are using a later version and the example seems outdated.

Constructing SpawnEggItem

The first step to registering a spawn egg item is to construct an item instance. Spawn eggs in particular use the SpawnEggItem class.

The constructor takes four parameters:

• type: The entity type to spawn
• primaryColor: The primary color for the item model
• secondaryColor: The secondary color for the item model
• settings: The general item settings

Altogether, constructing a SpawnEggItem should look like this:

public static final Item CUSTOM_ENTITY_SPAWN_EGG = new SpawnEggItem(ModEntityTypes.CUSTOM_ENTITY, 0xFF0000, 0x00FF00, new Item.Settings());

Registration

Afterwards, it should be registered somewhere as part of mod initialization:

Registry.register(Registries.ITEM, CUSTOM_ENTITY_SPAWN_EGG_ID, CUSTOM_ENTITY_SPAWN_EGG);

Vanilla spawn eggs are placed in the ItemGroups.SPAWN_EGGS item group in alphabetical order. Item group events be used to place the new spawn egg in that item group accordingly.

Item Model

Although the colors for the spawn egg were defined when constructing it, an item model still must be set. All spawn eggs can simply use the item/template_spawn_egg item model, as colors are applied to the spawn egg textures dynamically.

{
	"parent": "item/template_spawn_egg"
}
