This page describes content that is no longer in the game.
Most numeric IDs only exist in outdated versions of Minecraft.

These data values refer to the different types of blocks and items on Java Edition. They are used in many places in Minecraft. Block IDs are used to define blocks placed in the world and inventory items (including items in chests and items dropped in the world). Item IDs are only valid for items. There are also Entity IDs for entities such as mobs and projectiles. Block data further defines blocks placed, describing for example the height of water or the direction a torch points.

The list of Blocks and Items in Java Edition 1.12.2.

IDs[edit]

Key
I Has a different ID as an inventory item.
D Use the item's Damage field to define its durability.
S Requires additional data from the saved game's Data array to fully define the block.
B Requires additional data in the item's Damage field to fully define the inventory item.
N Requires additional data in the item's NBT data to fully define the inventory item.
E Requires a block entity to store additional data.
Red Cannot be legitimately obtained. Only available using the /give command or via inventory editors.
Light Blue Cannot be obtained as an item. (Can only be placed using block-placement commands such as /setblock or /fill.)
Blue Available in the Creative mode inventory by item list.
Purple Available in Creative mode by block picking.
Teal Can be obtained by trading with villagers or in the Creative mode inventory.
Green Only available by having Enchanted tools or in the Creative mode inventory.
Lime Green Only available by having Enchanted tools or via use of /give or inventory editors, but unobtainable in the Creative mode inventory.
Gray Unused data.


Horse Variants[edit]

Horse entities have variant fields that determine the markings on the horse. Below is a list of Variant values that determine the variant of horses.

White Creamy Chestnut Brown Black Gray Dark Brown
None 0 1 2 3 4 5 6
White 256 257 258 259 260 261 262
White Field 512 513 514 515 516 517 518
White Dots 768 769 770 771 772 773 774
Black Dots 1024 1025 1026 1027 1028 1029 1030

Variant names taken from the names of the texture file they correspond to.

Summoning a horse entity without specifying the Variant value, or using a Variant value that is not a true ID (all true IDs are displayed on the chart above), will result in a white horse.


Biome IDs[edit]

Each type of biome has its own biome id, shown in the following table. Main biomes have a numeric ID from 0 to 127, while biome variations normally have a numeric ID of 128 + <original biome number>. Extreme Hills Edge and Frozen Ocean biomes did not generate anymore.

Dirt[edit]

DV Description
0 Dirt
1 Coarse Dirt
2 Podzol


Saplings[edit]

The data value is split in half. The bottom three bits determine the type of sapling (and thus the eventual tree type), according to the following table:

Bits Values
0x1
0x2
0x4
A three-bit field storing a value of 0 to 5 specifying the type of sapling:
  • 0: Oak Sapling
  • 1: Spruce Sapling
  • 2: Birch Sapling
  • 3: Jungle Sapling
  • 4: Acacia Sapling
  • 5: Dark Oak Sapling
0x8 Set if sapling is ready to grow into a tree.

The 0x8 bit functions as the counter. The counter is cleared when a sapling is dropped as an item.

Water and Lava[edit]

If bit 0x8 is set, this liquid is "falling" and only spreads downward. At this level, the lower bits are essentially ignored, since this block is then at its highest fluid level.

The lower three bits are the fluid block's level. 0x0 is the highest fluid level (not necessarily filling the block - this depends on the neighboring fluid blocks above each upper corner of the block). Data values increase as the fluid level of the block drops: 0x1 is next highest, 0x2 lower, on through 0x7, the lowest fluid level. Along a line on a flat plane, water drops one level per meter from the source, lava drops one in the nether and two everywhere else.

The stationary versions of each fluid are "stable" and currently not being checked by the engine for further level changes. Oddly the in-code names for stationary water and lava are "water" and "lava" and the regular versions are "flowing_water" and "flowing_lava".

Sand[edit]

DV Description
0 Sand
1 Red sand


Wood[edit]

Block 17

Bits Values
0x1
0x2
A two-bit field storing a value of 0 to 3 specifying the type of wood:

  • 3: Jungle Wood
0x4
0x8
A two-bit field storing a value of 0 to 3 specifying the orientation of the wood:
  • 0: Facing Up/Down
  • 1: Facing East/West
  • 2: Facing North/South
  • 3: Only bark

Block 162

Bits Values
0x1
0x2
A two-bit field storing a value of 0 to 1 specifying the type of wood:
  • 0: Acacia Wood
  • 1: Dark Oak Wood
0x4
0x8
A two-bit field storing a value of 0 to 3 specifying the orientation of the wood:
  • 0: Facing Up/Down
  • 1: Facing East/West
  • 2: Facing North/South
  • 3: Only bark

Leaves[edit]

If bit 0x4 is set, the leaves are permanent and will never decay. This bit is set on player-placed leaf blocks and overrides the meaning of bit 0x8.

If bit 0x8 is set, the leaves will be checked for decay. The bit will be cleared after the check if the leaves do not decay. The bit will be set again whenever a block adjacent to the leaves is changed.

5 Facing up (attached to a block beneath it)


Slabs[edit]

Single slabs can be either "right-side-up" or "upside-down"; this information is stored in the most significant metadata bit 0x8 as follows:

  • 0: Slab is right-side-up, occupying the bottom half of its voxel.
  • 1: Slab is upside-down, occupying the top half of its voxel.

Thus a right-side-up birch wood slab has metadata value 0x2 (binary 0010), while an upside-down birch slab is represented by metadata 0xA (binary 1010).

Double slabs with the high-order bit set render the top texture on all six sides.

The wooden slab in the stone slabs has the properties of stone, and the texture of oak wood planks. They are unavailable in game and can only be obtained through commands.

Door[edit]

Minecraft 1.1 and Earlier[edit]

The two least significant bits are the orientation of the door, that is, the corner in which its hinge is positioned:

  • 0x0: northwest corner
  • 0x1: northeast corner
  • 0x2: southeast corner
  • 0x3: southwest corner

The two bits above are flags:

  • 0x8: If this bit is set, this is the top half of a door (else the lower half).
  • 0x4: If this bit is set, the door has swung counterclockwise around its hinge.

For example, the bottom half of a door with its hinge on the southwest corner, which is swung so that it is closed when viewed from the west, will have a data value of (3 | 4) = (3 + 4) = 7.

Starting at Minecraft 1.2 (from weekly snapshot 12w06a)[edit]

Graphic of possible door data values in 12w06a

The total data needed to accurately describe a single door tile is now contained in both door tiles, so both data values have to be inspected.

Common to both door tiles, the top bit (0x8) is as follows:

  • 0: The bottom half of the door
  • 1: The top half of the door

Top Sections

The least-significant bit (0x1) is as follows, assuming you're facing the same direction the door faces while closed:
  • 0: Hinge is on the right (this is the default for single doors)
  • 1: Hinge is on the left (this will be used for the other half of a double-door combo)
The other two bits (0x2 and 0x4) are always zero.
The only valid values for a top section, therefore, are 8 (binary 1000) and 9 (binary 1001).

Bottom Sections

The second bit (0x4) determines the door's state:
  • 0: Closed
  • 1: Open
The bottom two bits determine which direction the door faces (these directions given for which direction the door faces while closed)
  • 0: Facing east
  • 1: Facing south
  • 2: Facing west
  • 3: Facing north

Starting at Minecraft ??[edit]

The second bit for the top half of the door (0x2) determines whether the door is Powered or Unpowered.
  • 0: Door is Unpowered
  • 1: Door is Powered
Which means the top section, now uses values 8, 9, 10, and 11.

Vines[edit]

Determines the face against which the vine is anchored. Note that (except for Top) these are testable as bit flags, unlike most of the other directional data for other block types. Multiple sides can contain vines. The "top" attachment is assumed to be present if data is 0 or there is solid block above.

  • 1: south
  • 2: west
  • 4: north

2 ⅔ filled
3 Fully filled

End Portal Frame[edit]

The bottom two bits determine which "side" of the whole portal frame this block is a part of. To make the frame activate, each of the portal frame blocks in the pattern must "face" toward the middle. Since the image is near-symmetrical, it is difficult to tell which direction an individual block is actually facing, but if the block isn't facing in that direction and that is the last frame block where the Eye of Ender is placed, the frame won't activate.

Direction vectors for the blocks are the following:

  • 0: To the south
  • 1: To the west
  • 2: To the north
  • 3: To the east

0x4 is a bit flag: 0 is an "empty" frame block, 1 is a block with an Eye of Ender inserted.

8 Very Damaged Anvil (North/South)
9 Very Damaged Anvil (East/West)
10 Very Damaged Anvil (West/East)
11 Very Damaged Anvil (South/North)


For an anvil in the world, 0x1 is the bit that determines whether the anvil is orientated in a north-south (0) or a west-east (1) direction. 0x4 and 0x8 are bits which determine whether the anvil is a regular (0x4 & 0x8 = 0), a slightly damaged (0x4 = 1) or a very damaged (0x8 = 1) one. For an anvil in the inventory, the data value is a counter of how damaged it is.

0x2
0x4

Three bits storing a value from 0 to 5:

  • 0: Observer facing down
  • 1: Observer facing up

  • 3: Observer facing south
  • 4: Observer facing west
  • 5: Observer facing east
0x8 If set, the observer is powered.


Potions[edit]

A glass bottle filled with a potion. Potion type is stored in item's damage value as a 16-bit number. Potion effect, name, and other flags are encoded on bits. Effect duration itself isn't there, but can be calculated from other values.

Current meaning of bits is described below. Note that potion name overlaps with potion effect and tier.

Bit Dec Hex Meaning
0 1 0001 Potion effect Potion name
1 2 0002
2 4 0004
3 8 0008
4 16 0010
5 32 0020 Tier
6 64 0040 Extended duration
7 128 0080 (ignored)
8 256 0100
9 512 0200
10 1024 0400
11 2048 0800
12 4096 1000
13 8192 2000 Can become splash potion
14 16384 4000 Splash potion
15 32768 8000 (ignored)

To calculate damage value of potion with desired effect use the following formula:

DV = potion_effect + tier_bit + extended_bit + splash_bit

for example:

  • potion with "Instant Health" effect has damage value 5 (= 5 + 0 + 0 + 0);
  • potion with extended "Slowness" effect has value 74 (= 10 + 0 + 64 + 0);
  • splash potion with tier II "Strength" effect has value 16425 (= 9 + 32 + 0 + 16384).

To get potion with certain name, use the following formula:

DV = potion_name + extended_bit + splash_bit

for example:

  • Splash version of "Charming Potion" has damage value 16423 (= 39 + 0 + 16384)

Maps[edit]

Each map item's damage value corresponds to the map ID saved in each world's NBT data. The map's parameters, such as the scale of the map, its location in the world and what areas are explored are saved in separate .dat files, unlike written books or fireworks which store their additional data directly into the item itself. If a map is cloned they will both share the same damage value and newly explored areas will appear on both instances.
