The Slot data structure is how Minecraft represents an item and its associated data in the Minecraft Protocol.

Format

The structure consists of at least a short, which gives the item/block ID. A value of -1 signifies that the slot is empty, and no further data follows.

If the block ID is not -1, three more fields follow. These fields are a byte (item count), a short (item damage) and at least another byte.

If the byte is 0, there is no NBT data, and no further data follows. Otherwise the byte is the start of an NBT blob of the following format:

  COMPOUND ''
    LIST 'StoredEnchantments'
      COMPOUND
        SHORT 'id'
        SHORT 'lvl'
      END
      COMPOUND
        ...
      END
      ...
    END
    INT 'Unbreakable'
    ...
  END

See NBT for more information about the NBT format, and here for the contained information and its format.

Examples
