Block



Blocks are the basic units of structure in Minecraft.

Behavior
Together, solid blocks and liquid blocks build up the in-game environment and can be harvested and utilized in various fashions. Some blocks, such as dirt and sandstone, are opaque, while other blocks, such as glass and ice, are transparent.

Some blocks, such as torches and glowstone, will emit light. The amount of light they emit varies widely; see this table of light values for further information. Most opaque blocks will completely block light, while transparent blocks either have no effect on light or simply diffuse it.

Almost all blocks will ignore gravity, with the exception of sand, red sand, gravel, anvils, dragon eggs, concrete powder and, in Pocket Edition, layer snow.

Block height
Most solid blocks are 1 meter high, but certain blocks (especially slabs and stairs) have non-standard block heights.

A player can automatically step up from a lower to a higher height if the difference is at most 0.6 ($3/5$) of a block.

Textures
The textures on the faces of blocks are 16×16 pixels. Most blocks are proportionately one cubic meter by default, but their shape can be changed using models. Most blocks also have static textures, though water, lava, Nether portal, End portal, End gateway, fire, sea lantern, command block, prismarine, and magma blocks are animated.

Using resource packs, the player can change the textures and resolution of blocks, including whether their texture is animated. They can also change the shapes of blocks using models and the size of blocks to any size with equal width and height, though sizes that are a power of two tend to work better.

Natural blocks
Natural blocks are generated as part of the terrain in the Overworld, the Nether and the End. These also include ores and liquids.

Structures
These blocks are generated as part of structures.

Plants
Plants are Minecraft's representation of plant life. Most of them can grow and be farmed to obtain resources.

Manufactured
Manufactured blocks can only be obtained via crafting or smelting.

Utility
Utility blocks are used for a wide variety of specific purposes that are helpful to the player.

Mechanisms
Mechanisms can be used to perform a wide range of tasks.

Creative only
These blocks can only be accessed within the Creative mode inventory.

Commands only
These blocks can only be accessed with the use of commands, such as.

Pocket Edition/Windows 10 Edition only
These blocks can only be accessed in Pocket Edition and Windows 10 Edition. In these versions, item frames work as block entities.

Technical blocks


Technical blocks are blocks whose main functions are strictly tied to the usage of other blocks. They cannot be acquired through normal gameplay, most of them cannot be obtained with commands, but other ones require commands or mods to obtain. They serve various purposes during events within the game. If acquired, they will usually have a missing texture.

Many of these blocks have different representations in the inventory; flint and steel is used to place fire, water and lava can be placed with their respective buckets, and blocks such as beds, doors, cake and flower pots have separate inventory items altogether.
