Java Edition data values

For data values on mods that add new items, see Mod data values

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
These values apply to both inventory items and to blocks placed in the world. This reflects the most recent version. Entries marked with a D require additional data to fully define the block in a Beta world. Entries marked with an I have a different ID as an inventory item. Entries marked with a B require additional inventory data to fully define the inventory item. Items with IDs in red cannot be legitimately obtained in the player's inventory in the game; they can only be obtained by "hacking" (such as the use of Inventory editors) or, in multiplayer using the /give server command.

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 without hacking or, in multiplayer, the /give server command.

Data
Special data for certain block and item types. Storage differs according to level format.

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.

Saplings
0x0 is a freshly planted sapling. The data value is incremented at random intervals. When it becomes 15, a new tree is created in its place.

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.

Water and Lava
0x0 is a full block. Water goes up to 0x7, Lava can only go up to 0x3. 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).



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.
