Minecraft:Java Edition pre-flattening data values

Template:Exclusive Template:Outdated These data values refer to the different types of blocks and items on Template:El before the flattening in Minecraft:Java Edition 1.13. 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

Horse variants

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.

Minecraft:Saplings

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: Template:BlockSprite Oak Sapling 1: Template:BlockSprite Spruce Sapling 2: Template:BlockSprite Birch Sapling 3: Template:BlockSprite Jungle Sapling 4: Template:BlockSprite Acacia Sapling 5: Template:BlockSprite 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.

Minecraft:Water and Minecraft:Lava

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".

Wood

Minecraft:Leaves

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. <section end="metadata"/> Block 18 <section begin="metadata"/> Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt <section end="metadata"/> Block 161 <section begin="metadata"/> Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt <section end="metadata"/>

Minecraft:Wool, Minecraft:terracotta, Minecraft:stained glass and Minecraft:carpet

These values specify the color of the wool, stained terracotta, stained glass and carpet. This data is stored in block metadata for placed wool, stained clay, stained glass or carpet, and as the "damage" for the item in the inventory.

Minecraft:Slabs

Template:Info needed section 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.

Minecraft:Fire

0x0 is a placed or spread fire. Once it reaches 0xF the eternal fire-trick will work since there will be no further updates of the block.

Minecraft:Sandstone

For normal sandstone the bottom has a cracked pattern. The other types of sandstone have bottom faces same as the tops.

Minecraft:Beds

Lowest two bits value	Facing
0	Head facing South
1	Head facing West
2	Head facing North
3	Head facing East
Bit flag	Meaning
0x4	When 0, the bed is empty When 1, the bed is occupied
0x8	When 0, the foot of the bed When 1, the head of the bed

Double Plants

Double plants take up two vertical blocks. The bottom block defines the type, while the top defines the direction it faces (unused). When the most significant bit (0x8) is set, the plant is the top.

Minecraft:Piston

The top bit (0x8) is a status bit that determines whether the piston is pushed out or not. 1 for pushed out, 0 for retracted.

The bottom three bits are a value from 0 to 5, indicating the direction of the piston (the direction the piston head is pointing)

• 0: Down
• 1: Up
• 2: north
• 3: south
• 4: west
• 5: east

Piston Extension

The top bit (0x8) is a status bit that determines whether the head is sticky or not (note that the Piston Body actually has completely different block types for Sticky and Regular). 1 is sticky, 0 is regular.

The bottom three bits are a value from 0 to 5, indicating the direction of the piston (the direction the piston head is pointing).

• 0: Down
• 1: Up
• 2: north
• 3: south
• 4: west
• 5: east

Minecraft:Door

Minecraft 1.1 and Earlier

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

• 0x0: north-west corner
• 0x1: north-east corner
• 0x2: south-west corner
• 0x3: south-east 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 south-west 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)

File:12w06a-doors-idx.png

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 14w04a

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.

Minecraft:Nether Portal

Nether portals created in version 1.6.4 and earlier automatically determined their orientation based on neighboring blocks. When version 13w37a added the ability to create larger portals, they started using data values to keep track of their orientation, and old portals with a data value of 0 would randomly close when upgrading to 1.7.

DV	Orientation
0	Automatic, 1.6.4 and earlier
1	Facing North/South (obsidian to east and west)
2	Facing East/West (obsidian to north and south)

<section begin="metadata"/>

Minecraft:End Portal Frame

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 Minecraft:Eye of Ender inserted.

Minecraft:Flower Pots

For Flower Pot blocks placed from Minecraft version 1.7 on, the plant contained in the pot is stored in the associated Tile Entity. See Minecraft:Block entity format for details. The absence of a tile entity indicates either an empty Flower Pot, or one whose block was placed prior to version 1.7.

For Flower Pot blocks placed before version 1.7 the plant contained in the pot is indicated by the data value, according to the following table: Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt <section begin="metadata"/>

Minecraft:Fish

Both raw and cooked fish use the same data values. Note that clownfish and pufferfish cannot be cooked, though if cooked versions are spawned in with commands, they will use the appropriate item name.

Minecraft:Anvil

Anvil data values differ between the item and block.

Item Template:Dvt Template:Dvt Template:Dvt Block Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt Template:Dvt

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. <section begin="metadata"/>

Minecraft:Observer

Bits	Values
0x1 0x2 0x4	Three bits storing a value from 0 to 5: 0: Observer facing down 1: Observer facing up 2: Observer facing north 3: Observer facing south 4: Observer facing west 5: Observer facing east
0x8	If set, the observer is powered.

<section end="metadata"/>

Minecraft:Potions

A Minecraft: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)

Minecraft:Maps

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 Minecraft:written books or Minecraft: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. <section begin="metadata"/>

Minecraft:Chorus Flower

The data value denotes its age, it will not grow anymore when data value is 0x5.

Minecraft:Glazed Terracotta
