User:Anomie x/Materials

Materials in Minecraft classify blocks into different types, more or less indicating what the block is "made of".

Materials
The following materials exist in Minecraft. Each material gives certain properties to the block, although individual blocks can and often do override them.

Effects

 * Endermen will teleportation depends on which materials blocks movement: they choose a random destination and then seek downwards until they find a block with a movement-blocking material.
 * Various things that spawn on the "surface" similarly check material movement-blocking to find the surface.
 * Paintings, banners, signs, cakes, and mob heads are placed on any solid material. Which is why signs can be placed on each other without any visible connection.
 * Player spawning checks for obstruction by material solidity.
 * Lava checks for a burnable material when attempting to start fires nearby. But the fire itself uses its own list of flammable materials, which is why fire will start next to some wood blocks but will never consume the block.
 * Water and lava spread and currents generally depend on whether blocks' materials block movement, while placement from a bucket depends on solidity.
 * Fence gates must be placed above a block with a solid material.
 * When broken, ice turns to water when above a block with a liquid or movement-blocking material.
 * Cacti break depending on the solidity of adjacent blocks' materials.
 * Farmland turns to dirt if a solid-materialed block is placed on top.
 * Rain and snowfall fall through blocks that have non-liquid material that doesn't block movement.
 * Dungeon, lake, and Nether portal generation checks for solid materials, rather than solid blocks.
 * Solid-material blocks cannot be placed at Y=255, while non-solid-material blocks can.
 * Note block instruments check materials: stone, sand, glass, wood, and other.
