=== Mobs ===
None so far.
 
Mobs are spawned via [[Protocol#Spawn_Mob|Spawn Mob]]. There are two extra mob types in the code that refer to mobs classes that can never spawn: Mob and Monster (they are always subclasses, aka another more specific type).

=== Entity Metadata ===
 
Note that entity metadata is a totally distinct concept from block metadata. All entities must send at least one item of metadata, in most cases this will be the health item.
 
An Entity Metadata is an array of entries, each of which looks like the following:
 
{| class="wikitable"
! Name
! Type
! Meaning
|-
| Index
| Unsigned Byte
| Unique index key determining the meaning of the following value, see the table below. If this is <code>0xff</code> then the it is the end of the Entity Metadata array and no more is read.
|-
| Type
| Optional Byte Enum
| Only if Index is not <code>0xff</code>; the type of the index, see the table below
|-
| Value
| Optional ''value of Type''
| Only if Index is not <code>0xff</code>: the value of the metadata field
|}
 
{| class="wikitable"
! Value of Type field
! [[Data types|Type]] of Value field

|-
| 0
| Byte

| VarInt

| Rotation
| 3 floats: rotation on x, rotation on y, rotation on z
|-
| 8
| [[Data Types#Position|Position]]
|
|-
| 9
| OptPosition (Boolean + Optional Position)
| Position is present if the Boolean is set to true
|-
| 10
| Direction (VarInt)
| (Down = 0, Up = 1, North = 2, South = 3, West = 4, East = 5)
|-
| 11

| UUID is present if the Boolean is set to true
|-
| 12
| BlockID (VarInt)
| <code><nowiki>id &lt;&lt; 4 | data</nowiki></code>
|}
 
Entity classes also recursively use fields from classes they extend.
