Minecraft is all about the blocks. Here is everything you could ever want or need to know about them.
Minecraft Blocks Behavior
Collectively, solid blocks and blocks that are liquid build up the in-game surroundings and will be harvested and used in several manners. Some blocks, like sandstone and soil, are opaque, while other blocks, like glass and ice, are clear.
Some blocks, such as torches and glowstone, will emit light. The total amount of light they emit changes broadly; see this table of light values for further information. While clear blocks either don’t have any influence on light or just diffuse it most opaque blocks will completely block light.
Gravity will be ignored by nearly all blocks, together with the exception of concrete powder, red sand, gravel, anvils, dragon eggs, sand and, in Pocket Edition, layer snow.
Most solid blocks are 1 meter high, but particular blocks (especially slabs and stairway) have non-standard block heights.
Most blocks are proportionately one cubic meter by default, but their shape can be changed using versions. Most blocks also have static feels, prismarine, though water, lava, Nether portal, End portal, End portal site, fire, sea lantern, command block, and magma blocks are animated.
Using resource packs, the player can alter the textures and resolution including whether their feel is animated. They can also alter the contours of blocks using the size of blocks as well as versions to any size with equivalent width and height, though sizes which are a power of two often work better.
