Java Edition 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 an Alpha 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. Bold entries are not available in Alpha and italics entries are not available in Classic. Entries marked with a ^D require additional data to fully define the block in an Alpha world.

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.

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.

Soil

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 (not pictured).
