Stairs

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

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. It is not possible to make Stairs from Warped Planks.

Placement
To place stairs, a stairs item while pointing at a surface facing the space the stairs should occupy. When placed, a stair orients itself 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 places the stairs right side up.
 * Pointing at a block bottom or the top half of a block side places the stairs upside-down.

Stairs 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 wraps 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 shortens to join the other stairs' full-block side (it creates an "outer corner").

Right side up stairs do not join with upside-down stairs and vice versa.

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

Behavior
Generally, the solid faces of stairs are handled as solid blocks. Due to this, transparent blocks that need to placed on an opaque surface can be placed on these faces.

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

Note Blocks
Wooden stairs can be placed under note blocks to produce "bass" sound.

Stone stairs can be placed under note blocks to produce "bass drum" sound.
