Java Edition data values

From Minecraft Wiki
Jump to: navigation, search
Java Edition.png

These data values refer to the different types of blocks and items. They are used in many, 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.

Contents

IDs[edit | edit source]

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.
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 no matter what. (Can only be placed using /setblock)
Blue Available in Creative mode by item list.
Purple Available in Creative mode by block picking.
Teal Can be obtained by trading with villagers or in Creative mode.
Green Only available by having Enchanted tools or in Creative mode.
Lime Green Only available by having Enchanted tools or via use of /give or inventory editors, but unobtainable in the Creative mode menu.
Gray Unused data.

Entity IDs

Horse Variants[edit | edit source]

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 will result in a white horse.

Using a Variant value that is not a true ID (all true IDs are displayed on the chart above) will result in an invisible horse.

Biome IDs[edit | edit source]

Each type of biome has its own biome number, shown in the following table. These biome numbers are used when creating a customized superflat world. Main biomes have an ID number from 0 to 127, while biome variations normally have an ID number of 128 + <original biome number>. Two biomes, FrozenOcean (10) and Extreme Hills Edge (20) are no longer naturally generated.

Dirt[edit | edit source]

DV Description

0 Dirt

1 Coarse Dirt

2 Podzol

Saplings[edit | edit source]

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 | edit source]

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 | edit source]

  • 3:
    Only bark

Leaves[edit | edit source]

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.

Slabs[edit | edit source]

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 | edit source]

Minecraft 1.1 and Earlier[edit | edit source]

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 | edit source]

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 | edit source]

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 | edit source]

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
  • 8: east

DV Description
0 Empty
1 ⅓ filled
2 ⅔ filled
3 Fully filled

End Portal Frame[edit | edit source]

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.

DV Description
0 Facing down
1 Facing up
2 Facing south
3 Facing north
4 Facing east

Potions[edit | edit source]

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 | edit source]

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.

Trivia[edit | edit source]

  • Using /give command or inventory editors, an item can be spawned with its data value out of normal bounds. This can cause a normal looking item to appear, but will be unusable and unstackable with an identical item that has a different data value. Examples are provided:
  1. Stacking: If the player were to type /give <player> dye, an Ink Sac would be given to the player like normal. However, if the player were to type /give <player> dye 1 16 afterward, another Ink Sac would be given, but it won't stack with the first one, because they have different data values.
  2. Non-usable: Note that the valid data values for dye are between the numbers 0 and 15. Any type of dye that's spawned with a data value higher than 15 cannot be used.
