Entity Type Registry

Entity types are registered in EntityIO::staticCtor() in Minecraft.World/EntityIO.cpp. Each call to EntityIO::setId() maps a factory function, an internal enum value (eINSTANCEOF), a string identifier, and a numeric ID.

Entities that can be spawned in Creative mode through the Spawn Egg also include egg colors and a name string ID.

Note

In the LCEMP source, IDs 3-8, 19, 22-39, 42-47, 64-89, 100-119, 121-199, 201-999 are unassigned. The base types Mob (48) and Monster (49) are registered but act as generic fallbacks; specific mob types override them.

Additional Entities (MinecraftConsoles)

The MinecraftConsoles repo adds these entities not present in the LCEMP source:

ID	String ID	Enum	Class	Category
8	LeashKnot	eTYPE_LEASHFENCEKNOT	LeashFenceKnotEntity	Misc
12	Fireball	eTYPE_FIREBALL	LargeFireball	Projectile
19	WitherSkull	eTYPE_WITHER_SKULL	WitherSkull	Projectile
22	FireworksRocketEntity	eTYPE_FIREWORKS_ROCKET	FireworksRocketEntity	Misc
42	MinecartRideable	eTYPE_MINECART_RIDEABLE	MinecartRideable	Vehicle
43	MinecartChest	eTYPE_MINECART_CHEST	MinecartChest	Vehicle
44	MinecartFurnace	eTYPE_MINECART_FURNACE	MinecartFurnace	Vehicle
45	MinecartTNT	eTYPE_MINECART_TNT	MinecartTNT	Vehicle
46	MinecartHopper	eTYPE_MINECART_HOPPER	MinecartHopper	Vehicle
47	MinecartSpawner	eTYPE_MINECART_SPAWNER	MinecartSpawner	Vehicle
64	WitherBoss	eTYPE_WITHERBOSS	WitherBoss	Boss
65	Bat	eTYPE_BAT	Bat	Passive Mob
66	Witch	eTYPE_WITCH	Witch	Hostile Mob
100	EntityHorse	eTYPE_HORSE	EntityHorse	Passive Mob

Note

In MinecraftConsoles, the single Minecart entity (LCEMP IDs 40-41) was split into separate classes: MinecartRideable (42), MinecartChest (43), MinecartFurnace (44), MinecartTNT (45), MinecartHopper (46), and MinecartSpawner (47). Boat moved from ID 41 to stay at 41. The old Minecart ID 40 was removed.

The Fireball class was renamed to LargeFireball to differentiate from SmallFireball. The Ozelot class was renamed to Ocelot but keeps the string ID "Ozelot".

Horse variants (donkey, mule, skeleton horse, zombie horse) are registered as the same EntityHorse class at ID 100 but with different sub-type bits shifted into the upper 12 bits of the ID. In non-content-package builds, extra ocelot cat types and a spider jockey variant are also registered.

Spawnable Entities (Spawn Eggs)

These entities can be spawned with the Spawn Egg item (ID 383) using the entity ID as the data value. They’re the entities registered with the SpawnableMobInfo overload of setId():

LCEMP Spawn Eggs

Entity ID	Name
50	Creeper
51	Skeleton
52	Spider
54	Zombie
55	Slime
56	Ghast

MinecraftConsoles Additional Spawn Eggs

Entity ID	Name
63	EnderDragon (has egg colors in MinecraftConsoles but not LCEMP)
65	Bat
66	Witch
100	EntityHorse (Horse)
100 + sub	Donkey, Mule (sub-type encoded in upper bits)

Note

Giant (53), SnowMan (97), VillagerGolem (99), and WitherBoss (64) are registered entities but do not have spawn eggs in either codebase.

In non-content-package builds, extra spawn eggs exist for skeleton horse, zombie horse, individual ocelot cat types, and a spider jockey.

ID Ranges

The entity ID space follows Minecraft’s standard conventions:

Range	Category
1-2	Dropped items and XP orbs
8	Leash knot (MinecraftConsoles only)
9-19	Paintings, projectiles, item frames, wither skulls
20-22	Physics blocks (TNT, falling sand), fireworks rockets
41-47	Vehicles (boat, minecart variants)
48-66	Hostile mobs, bosses (and base mob types)
90-100	Passive and utility mobs, horses
120	Villager
200	Ender Crystal
1000	Dragon Fireball
