These entities are generally unaffected by potion effects, so it doesn't matter that they reuse the same index.

This item stack will be a FIREWORK with the effects stored in its additional NBT data (meta item in Bukkit).

0 for ordinary animals.

Baby animals have the value -23999. This corresponds to the number of ticks in a minecraft day, which is how long it takes for a baby animal to "grow up". It is therefore considered likely that this field determines the size of the animal, and that Entity Metadata will update it as the animal grows.

When an animal becomes a parent this value is set to 6000 and is then decreased over time. Probably a countdown until they can have a new baby.

Entity Metadata

Entity Metadata Format

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.

The entity metadata format is quirky dictionary format, where the key and the value's type are packed in a single byte.

To parse, repeat the following procedure:

  1. Read an unsigned byte
  2. If this byte == 127, stop reading
  3. Decompose the byte.
    The bottom 5 bits (0x1F) serve as an identifier (key) for the data to follow.
    The top 3 bits (0xE0) serve as a type.
  4. Read and unpack based on the type (below)
Type Meaning
0 Byte
1 Short
2 Int
3 Float
4 String16
5 Slot
6* Int, Int, Int (x, y, z)

*Not currently used


In C-like psuedocode: 

do {
    item = readByte();
    if (item == 0x7F) break;
    var index = item & 0x1F;
    var type = item >> 5;
    
    if (type == 0) metadata[index] = readByte();
    if (type == 1) metadata[index] = readShort();
    if (type == 2) metadata[index] = readInt();
    if (type == 3) metadata[index] = readFloat();
    if (type == 4) metadata[index] = readString16();
    if (type == 5) metadata[index] = readSlot();
    if (type == 6) {
        var vector;
        vector.x = readInt();
        vector.y = readInt();
        vector.z = readInt();
        metadata[index] = vector;
    }
} while (true);
