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. Each inventory slot has a unique slot number. In a Beta world, Block data further defines blocks placed, describing for example the height of water or the direction a torch points.
IDs
Block IDs (Minecraft Official Release)
These values apply to both inventory items and to blocks placed in the world. This reflects the most recent version.
D | Requires additional data from the saved game's Data array to fully define the block. |
I | Has a different ID as an inventory item. |
B | Requires additional data in the item's Damage field to fully define the inventory item. |
T | Requires a tile 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 ever. |
Blue | Only available in Creative mode. |
Green | Only available by having Enchanted tools or in Creative mode. |
Yellow-green | Only available by having Enchanted tools, but unobtainable in Creative mode. |

Item IDs
All items have values above 255, making it easy to separate the Block IDs from the Item IDs. Entries marked with a D require additional data to fully define the item in a Beta world. The chainmail set is currently unobtainable in Survival mode without hacking or, in multiplayer, the /give server command. It is available in Creative mode, however.

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.
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.

Saplings
Prior to Beta 1.5
Prior to Beta 1.5, this data value was a counter which started at 0x0 (for a freshly-planted sapling) and was increased at random intervals. Once the counter hit 15, a new tree was created in its place.
Beta 1.5 and after
As of Beta 1.5, the data value is split in half. The bottom two bits now determine the type of sapling (and thus the eventual tree type), according to the following table:
Icon | Value | Description |
---|---|---|
0 | Oak Sapling | |
1 | Spruce Sapling | |
2 | Birch Sapling | |
3 | Dropped by Jungle Leaves, but otherwise is oak sapling | |
4+ | Same as 3, but never dropped |
The top two bits function as the counter, as in pre-1.5 builds, though obviously there are only four values available in the remaining bits. Either the counter is incremented more slowly to compensate, or trees might just grow more quickly since the update.
Cactus
0x0 is a freshly planted cactus. The data value is incremented at random intervals. When it becomes 15, a new cactus block is created on top as long as the total height does not exceed 3.
Sugar Canes
0x0 is a freshly planted cane. The data value is incremented at random intervals. When it becomes 15, a new sugar cane block is created on top as long as the total height does not exceed 3.
Water and Lava
0x0 is a full block. Water goes up to 0x7, Lava goes up to 0x6 (using the steps 0x0, 0x2, 0x4 and 0x6). If bit 0x8 is set, this liquid is "falling" and only spreads downward.
Farmland
0x0 is dry land, 0x1-0x8 are increasing levels of wetness. The wetness value depends on how far the block is away from water.
Crops
Crops grow from 0x0 to 0x7.

Pumpkin stem and Melon stem
Pumpkin and melon stems grow from 0x0 to 0x7. During each stage of growth a part of their model is revealed. In the last stage a stem can spawn a melon or pumpkin next to it on empty farmland. As long as this fruit remains the stem will appear bent towards the fruit.
Wool
These values specify the color of the wool. This data is stored in block metadata for placed wool, and as the "damage" for wool in the inventory.

Rails
Regular Minecart rails use values above 0x5 for the corner pieces. For powered rails, 0x8 is a bit flag indicating whether or not it is powered, and the bottom three bits have a valid range of 0x0 to 0x5.
- 0x0: flat track going Template:F-Template:F
- 0x1: flat track going Template:F-Template:F
- 0x2: track ascending to the Template:F
- 0x3: track ascending to the Template:F
- 0x4: track ascending to the Template:F
- 0x5: track ascending to the Template:F
Regular minecart tracks can make a circle from four rails:
- 0x6: Template:F corner (connecting Template:F and Template:F)
- 0x7: Template:F corner (connecting Template:F and Template:F)
- 0x8: Template:F corner (connecting Template:F and Template:F)

- 0x1: Ascending Template:F
- 0x2: Ascending Template:F
- 0x3: Ascending Template:F
Starting in Minecraft 1.2 (actually weekly 12w08a), the bit at 0x4 is used as follows:
- 0: Stairs are regular
- 1: Stairs are upside down
Levers
- 0x8: If this bit is set, the lever has been thrown and is providing power.
Wall levers:
- 0x1: Facing Template:F
- 0x2: Facing Template:F
- 0x3: Facing Template:F
- 0x4: Facing Template:F
Ground levers:
- 0x5: Lever points Template:F when off.
- 0x6: Lever points Template:F when off. (Note that unlike the other types of switch, this version didn't power wires around the block it was sitting on. This bug was fixed in Beta 1.6)
Doors
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: Template:F corner
- 0x1: Template:F corner
- 0x2: Template:F corner
- 0x3: Template:F 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 Template:F corner, which is swung so that it is closed when viewed from the Template:F, will have a data value of (3 | 4) = (3 + 4) = 7.
Starting at Minecraft 1.2 (from weekly snapshot 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 Template:F
- 1: Facing Template:F
- 2: Facing Template:F
- 3: Facing Template:F
Buttons
- 0x8 If this bit is set, the button has been pressed. If this bit is set in a saved level, the button will remain pressed for an undefined length of time after the level is loaded.
Button direction:
- 0x1: Facing Template:F
- 0x2: Facing Template:F
- 0x3: Facing Template:F
- 0x4: Facing Template:F
Sign Posts
- 0x0: Template:F
- 0x1: Template:F-Template:F
- 0x2: Template:F
- 0x3: Template:F-Template:F
- 0x4: Template:F
- 0x5: Template:F-Template:F
- 0x6: Template:F
- 0x7: Template:F-Template:F
- 0x8: Template:F
- 0x9: Template:F-Template:F
- 0xA: Template:F
- 0xB: Template:F-Template:F
- 0xC: Template:F
- 0xD: Template:F-Template:F
- 0xE: Template:F
- 0xF: Template:F-Template:F
Ladders, Wall Signs, Furnaces, Dispensers and Chests
- 0x2: Facing Template:F (for ladders and signs, attached to the Template:F side of a block)
- 0x3: Facing Template:F
- 0x4: Facing Template:F
- 0x5: Facing Template:F
Pumpkins and Jack-O-Lanterns
- 0x0: Facing Template:F
- 0x1: Facing Template:F
- 0x2: Facing Template:F
- 0x3: Facing Template:F
Pressure Plates
- 0x1: If this bit is set, the plate is pressed.
Slabs and Double Slabs
For both slabs and double slabs, the lower three bits of the metadata nybble determine the texture:
Icon | Value | Description |
---|---|---|
0x0 | Stone Slab | |
0x1 | Sandstone Slab | |
0x2 | Wooden Slab | |
0x3 | Cobblestone Slab | |
0x4 | Brick Slab | |
0x5 | Stone Brick Slab |
Half-slabs can be either "right-side-up" or "upside-down"; this information is stored in the most significant metadata bit 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 wooden slab has metadata value 0x2 (binary 0010
), while an upside-down wooden slab is represented by metadata 0xA (binary 1010
). Double slabs do not make use of the high-order bit of the metadata value.
Upside-down slabs were implemented in Weekly Release 12w08a and introduced officially in Minecraft 1.2. Brick slabs and stone brick slabs were added in Beta 1.8.
Snow
- 0x0: Normal snowfall height
- ...
- 0x7: Full block size height
The height repeats for values 8-15. Note that snow does not occur naturally at other heights than 0, but can be edited or hacked in. Values 0-2 has no hitbox, values 3-7 has the same hitbox as a slab.
Cake
- 0x0: 0 pieces eaten
- 0x1: 1 piece eaten
- 0x2: 2 pieces eaten
- 0x3: 3 pieces eaten
- 0x4: 4 pieces eaten
- 0x5: 5 pieces eaten
Beds
- 0x0: Head is pointing Template:F
- 0x1: Head is pointing Template:F
- 0x2: Head is pointing Template:F
- 0x3: Head is pointing Template:F
- 0x4: (bit flag) - When 0, the bed is empty. When 1, the bed is occupied.
- 0x8: (bit flag) - When 0, the foot of the bed. When 1, the head of the bed.
Redstone Repeater
Low (1st & 2nd) bits:
- 0x0: Facing Template:F
- 0x1: Facing Template:F
- 0x2: Facing Template:F
- 0x3: Facing Template:F
High (3rd & 4th) bits:
- 0x0: 1 tick delay
- 0x1: 2 tick delay
- 0x2: 3 tick delay
- 0x3: 4 tick delay
Redstone Wire
0xF is a wire placed right next to a power source (like a redstone torch). The value declines with distance until 0x0, which is a non-powered wire. The direction of the wire is not saved but calculated at runtime.
Tall Grass
Icon | Value | Description |
---|---|---|
0x0 | Dead shrub (identical in appearance to block Dead Bush when placed, but acts like Tall Grass) | |
0x1 | Tall grass | |
0x2 | Fern |
Trapdoors
0x4 is a bit that determines whether or not the trapdoor is swung open. 0 for closed (on the ground), 1 for open (against its connecting wall). The remaining two bits describe which wall the trapdoor is attached to:
- 0x0: Attached to the Template:F wall
- 0x1: Attached to the Template:F wall
- 0x2: Attached to the Template:F wall
- 0x3: Attached to the Template:F wall
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: Template:F
- 3: Template:F
- 4: Template:F
- 5: Template:F
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: Template:F
- 3: Template:F
- 4: Template:F
- 5: Template:F
Stone Brick
Icon | Value | Description |
---|---|---|
0x0 | Normal | |
0x1 | Mossy | |
0x2 | Cracked | |
0x3 | Circle |
Huge brown and red mushroom
Huge mushrooms consist of the same blocks throughout their structure, the data value of each block decides the texture. The default texture on all sides is porous flesh. The cap texture can be either the brown mushroom or red mushroom texture, the textures for porous and stem sides are identical.
Value | Description | Textures |
---|---|---|
0 | Fleshy piece | Pores on all sides |
1 | Corner piece | Cap texture on top, Template:F and Template:F |
2 | Side piece | Cap texture on top and Template:F |
3 | Corner piece | Cap texture on top, Template:F and Template:F |
4 | Side piece | Cap texture on top and Template:F |
5 | Top piece | Cap texture on top |
6 | Side piece | Cap texture on top and Template:F |
7 | Corner piece | Cap texture on top, Template:F and Template:F |
8 | Side piece | Cap texture on top and Template:F |
9 | Corner piece | Cap texture on top, Template:F and Template:F |
10 | Stem piece | Stem texture on all four sides, pores on top and bottom |
Vines
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: Template:F
- 2: Template:F
- 4: Template:F
- 8: Template:F
Fence Gates
0x4 is a bit flag: 1 is open, 0 is closed. The remaining two bits determine in which direction the gate will open.
- 0: To the Template:F
- 1: To the Template:F
- 2: To the Template:F
- 3: To the Template:F
Hidden Silverfish
A silverfish will hide inside a Stone, Cobblestone, or Stone Brick block, changing it into a Hidden Silverfish block. The data value tells us its appearance:
- 0: Stone
- 1: Cobblestone
- 2: Stone Brick
Potions
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 | 0800 | (ignored) | |
8 | 256 | 0100 | ||
9 | 512 | 0200 | ||
10 | 1024 | 0400 | ||
11 | 2048 | 0800 | ||
12 | 4096 | 1000 | ||
13 | 8192 | 2000 | ||
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 Charming Potion" has damage value 16422 (= 38 + 0 + 16384)

Brewing Stand
The bottom three bits are bit flags for which bottle slots actually contain bottles. The actual bottle contents (and the reagent at the top) are stored in a TileEntity for this block, not in the data field.
- 0x1: The slot pointing Template:F
- 0x2: The slot pointing Template:F
- 0x4: The slot pointing Template:F
Cauldron
The data value stores the amount of water kept in the cauldron, in units of glass bottles that can be filled.
- 0: Empty
- 1: 1/3 filled
- 2: 2/3 filled
- 3: Fully filled
End Portal Frame
The bottom two bits determine which "side" of the whole portal frame this block is a part of.
0x4 is a bit flag: 0 is an "empty" frame block, 1 is a block with an Eye of Ender inserted.
Spawn Eggs
Damage values on Spawn Eggs will cause it to spawn the Entity of that ID. For example, a damage value of 2 would cause the spawner egg to create Experience Orbs.
