Data values

This article is about data values found in the latest unmodified PC version of Minecraft. For data values added by mods, see Mods/Data values. For data values found in Classic, see Data values (Classic). For data values found in Pocket Edition, see Data values (Pocket Edition).

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.

Block IDs (Minecraft Beta)

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.
Blue	Only available in Creative mode.
Green	Only available by having Enchanted tools or 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.

Wood

Icon	Value	Description
	0	Is the usual trunk texture
	1	Is the spruce like texture
	2	Is a birch texture

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 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.

Icon	Value	Description
	0	Is the usual tree's leaves texture
	1	Is the spruce tree's leaves texture
	2	Is a birch tree's leaves texture
	3	Is the usual tree's leaves texture but with the spruce tree's leaves color

Coal

Icon	Value	Description
	0	Coal
	1	Charcoal

Jukebox

Icon	Value	Description
	0	Nothing
	1	Gold Music Disc
	2	Green Music Disc

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	Usual Sapling
	1	Spruce Sapling
	2	Birch Sapling
	3	n/a - defaults to "usual"

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 (Pictured below).

Icon	Value

	2
	3

	6
	7

Nether Wart

Like Crops, the data value is related to the size of the Nether Wart. There are three distinct visual stages to Nether Wart's growth (the associated data values are given):

• Small: 0
• Medium: 1-2
• Large: 3

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

Note: Only the default wool block - block ID #35 - can be spawned using the /give method. The materials for dying wool must be spawned or collected in order to get colored 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.

Torches and Redstone Torches

• 0x1: Pointing East
• 0x2: Pointing West
• 0x3: Pointing South
• 0x4: Pointing North
• 0x5: Standing on the floor

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 North-South
• 0x1: flat track going West-East
• 0x2: track ascending to the East
• 0x3: track ascending to the West
• 0x4: track ascending to the North
• 0x5: track ascending to the South

Regular minecart tracks can make a circle from four rails:

• 0x6: WestNorth corner (connecting East and South)
• 0x7: EastNorth corner (connecting West and South)
• 0x8: EastSouth corner (connecting West and North)
• 0x9: WestSouth corner (connecting East and North)

Ladders

• 0x2: Attached to the North side of a block
• 0x3: South side of a block
• 0x4: West side
• 0x5: East side

Stairs

• 0x0: Ascending East
• 0x1: Ascending West
• 0x2: Ascending South
• 0x3: Ascending North

Levers

• 0x8: If this bit is set, the lever has been thrown and is providing power.

Wall levers:

• 0x1: Facing East
• 0x2: Facing West
• 0x3: Facing South
• 0x4: Facing North

Ground levers:

• 0x5: Lever points South when off.
• 0x6: Lever points East 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

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.

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 East
• 0x2: Facing West
• 0x3: Facing South
• 0x4: Facing North

Sign Posts

• 0x0: South
• 0x1: South-Southwest
• 0x2: Southwest
• 0x3: West-Southwest

• 0xC: East
• 0xD: East-Southeast
• 0xE: Southeast
• 0xF: South-Southeast

Wall Signs

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

Stone Brick

• 0: Normal
• 1: Mossy
• 2: Cracked

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, West and North
2	Side piece	Cap texture on top and North
3	Corner piece	Cap texture on top, North and East
4	Side piece	Cap texture on top and West
5	Top piece	Cap texture on top
6	Side piece	Cap texture on top and East
7	Corner piece	Cap texture on top, South and West
8	Side piece	Cap texture on top and South
9	Corner piece	Cap texture on top, East and South
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: South
• 2: West
• 4: North
• 8: East

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 South
• 1: To the West
• 2: To the North
• 3: To the East

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. Code snippet has been moved to the Talk page, if anyone feels like puzzling it out there.

• 0: Mundane Potion (No Effects)
• ...

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 East
• 0x2: The slot pointing Southwest
• 0x4: The slot pointing Northwest

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

Air Portal Frame

In Beta 1.9pre4

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.

In Beta 1.9pre3

• 0: denotes a full, "fixed" block
• 1: denotes a "broken" block
