Stairs

Stairs are blocks that allow mobs and players to change elevation without jumping.

Obtaining
Stairs can be crafted, or can be found in villages, strongholds, temples, nether fortresses, end cities and woodland mansions.

Breaking
Wood stairs drop themselves as items when broken with any tool, or with no tool, but an axe is fastest. Non-wood stairs drop themselves as items only if broken with a pickaxe.

Crafting
Wood stairs must be crafted entirely from one type and color of wood, and they retain the style of that wood's type and color.

Natural generation

 * Oak and cobblestone stairs generate naturally in plains villages.
 * Acacia stairs generate naturally in savanna villages.
 * Sandstone stairs generate naturally in some warm underwater ruins.
 * Cobblestone and stone brick stairs generate naturally in strongholds.
 * Nether brick stairs generate naturally in nether fortresses.
 * Stone brick stairs generate naturally in some cold underwater ruins.
 * Spruce stairs generate naturally in witch huts and in igloo basement.
 * Spruce and diorite stairs generate in snowy taiga and snowy tundra villages.
 * Spruce and cobblestone stairs generate in taiga and snowy taiga villages.
 * Purpur stairs generate naturally in end cities.
 * Oak, dark oak and birch stairs as well as cobblestone stairs generate naturally in woodland mansions.
 * Oak, birch, spruce, jungle, acacia, and dark oak stairs can generate naturally in shipwrecks.
 * Dark oak and mossy cobblestone stairs can generate in pillager outposts.
 * Sandstone, smooth sandstone, and granite stairs generate in desert villages.

Stonecutter
Any kind of stairs (except for wooden stairs) can be obtained by placing one block of the same type (for example: stone for stone stairs, sandstone for sandstone stairs, ecc.) in the input slot of a stonecutter.

Walking
Walking up stairs is faster than jumping up the same distance. It also only costs 0.01 exhaustion from the player's hunger bar per horizontal meter walked on a stairway, versus 0.2 exhaustion per jump.

Placing
To place stairs, a stairs item while pointing at a surface facing the space the stairs should occupy. Stairs will place with the half-block side closest to the player.

Stairs can be placed either right side up or upside-down:
 * Pointing at a block top or the bottom half of a block side will place the stairs right side up.
 * Pointing at a block bottom or the top half of a block side will place the stairs upside-down.

Stairs will change their shape to join with adjacent stairs (of any material):
 * When a stairs' half-block side is adjacent to the side of another stairs, the stairs' full-block side will wrap into an "L" shape to join the other stairs (it creates an "inner corner").
 * When a stairs' full-block side is adjacent to the side of another stairs, the stairs' full-block side will shorten to join only the other stairs' full-block side (it creates an "outer corner").

Right side up stairs won't join with upside-down stairs and vice versa.

Fuel
Wooden stairs can be used as a fuel in furnaces, smelting 1.5 items per block.
