Block



Blocks are the basic units in Minecraft, and are essential to the gameplay. Together, they build up the in-game environment, and can be mined and utilized in various fashions. There are one hundred and fifty three different blocks.

The face of a block is 16×16 pixels, and each block is proportionately one cubic meter. Most blocks are static, although water, lava, portal, and fire blocks have a shifting pattern for each face.

World-generated blocks
Entries marked with a D require additional data values to fully define the block in a Minecraft 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 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.

Block height

 * Add info on beds, slabs, redstone repeaters, flower pots, etc., and changes in player movement/height due to these "transparent" block types.

Beds, slabs, redstone repeaters, enchantment tables, flower pots, etc. all have non-standard block heights that allows the player to automatically move onto them without jumping (with the exception of the flower pot), or causes the player to have to jump in order to move forward if the blocks are used in conjunction with regular-sized blocks. This is apparent with soul sand, as it can be used in front of a 1 x 2 block doorway to create a one-way entrance. This is due to the fact that soul sand is slightly less than 1 block in height.

Bugs

 * When placing a block in any version of Minecraft with a slow, laggy computer, two blocks may be placed when only clicking once, and when attempting to remove one block, two blocks may be removed. This also happens with doors. People with particularly low-end hardware may even experience three blocks being placed or removed with one click of the mouse. A good way of combating this problem is by reducing the render distance or by using mods like optifine to change the game settings and speed up the game.

Trivia
!
 * - Zombies, Skeletons, Wither Skeletons, and Villager Zombies have a chance to spawn with a Pumpkin on their head IF your computer's date is set to October 31'st (tested in S.S.P.).
