Block



Blocks are the basic units of structure in Minecraft. Together, they build up the in-game environment and can be mined and utilized in various fashions. There are one hundred fifty-three different blocks as of version 1.7.9 (The latest version).

The textures on the faces of blocks are 16×16 pixels by default, but players can utilize resource packs that increase the resolution allowing textures to be 32x32, 64x64, 128x128, 256x256, 512x512, or (rarely) 768x768, 1024x1024 and 2048x2048 pixels. No matter what the resource pack, however, each block is proportionately one cubic meter. Most blocks have static textures, with the exception of water, lava, portal, and fire blocks, which have a shifting pattern for each face. All blocks, with the exception of sand, gravel and active TNT, ignore gravity.

World-generated blocks
Entries marked with a D require additional data values to fully define the block in the 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. Entries marked with a T have tile entities associated with them to store additional data. Items with IDs in red cannot be legitimately obtained by the player in the game; they can only be obtained by using inventory editors or the /give command. Items with IDs in light blue can never be obtained no matter what. Items available only in Creative mode are in blue. Items only obtainable through the Silk Touch enchantment in survival mode are in green.

Naturally generated
"Naturally generated" includes blocks that are created through the world seed.

Naturally created
"Naturally created" means a combination of events that caused a new block to be placed by natural causes, not the player.

Structures
Same as "naturally generated", but these blocks are created with the "generate structures" option enabled.

Structures
These blocks are generated as part of Nether fortresses. Even if the "Generate Structures" option is turned off, Nether fortresses are still created.
