Stairs

Stairs are blocks that allow the player to change elevation without jumping. They are a more compact alternative to Slabs, allowing a greater elevation change in a shorter horizontal distance.

Occurrence
Stairs occur naturally in NPC Villages. Wooden Stairs make seating furniture in houses, as well as roofs for most structures in the village. Cobblestone Stairs occur in front of doors and inside churches. Cobblestone Stairs can also be found within Strongholds. Nether Brick Stairs occur naturally in Nether Fortresses.

Crafting
Stairs can be made using six of either Wooden Planks, Cobblestone, Bricks, Stone Bricks, or Nether Bricks, producing four stairs per craft. Before 1.9pre6, upon destroying the block after placement, it would yield only one of the original material.

Up to version 1.8.1, Stone Brick Stairs could drop one of either Mossy Stone Brick or Cracked Stone Brick when broken.

Usage
Aside from their obvious usage, stairs can be used for a number of aesthetic purposes, mostly in simulating items that are not currently present in the game.


 * A popular use for stair blocks is to simulate benches or chairs. As of the Beta 1.8 update, NPC Villages are generated using stairs for seats.
 * Another popular use is as roofing for homes, also seen in NPC Villages but widely used by players prior to the 1.8 Beta update.
 * Brick and stone brick steps, when stacked at the end of a wall made with other brick or stone brick blocks, gives the appearance of broken masonry.

Behavior
As of Alpha 1.2.0 (the Halloween update) Stairs are placed facing the player so they may be immediately climbed. This may cause problems when constructing a stair; just start at the lower end to fix this. Alternatively, you can face the top of the stairs, sneak, and place stairs at your feet while hanging onto the edge of a block to place them in the correct location while descending the stairs.

Water will flow over stairs as if it were a completely solid block. If one attempts to place a torch on top of a stair block, the torch will be placed instead on the closest available non-stair block.

Previously, Wooden Stairs would not burn, but as of Beta 1.6, Wooden Stairs and Fences have become flammable.

History

 * In earlier versions, mining a stair block would yield it's base block, rather than a stair block.
 * In earlier versions, hovering the cursor over the stair block would sometimes make the black outline flicker, making mining the stair block glitchy, and the block behind it would often be mined instead.
 * Stairs used to face a direction automatically when placed. They would attempt to face a block adjacent to the stairs, so as to create a climbable surface towards that block. However, this was often more annoying than helpful, and was therefore changed to be placed facing the player.
 * From Alpha version 1.2.0_02 to Beta 1.5, stairs had the odd property of being transparent to light; when placed one or more spaces above the ground with air beneath, sunlight or other light sources would shine through and light the blocks beneath/behind the stairs exactly as if nothing opaque were present between them. Other atmospheric effects such as snowfall did not penetrate stair blocks, making them an unusually effective material for creating roofing which kept weather out, but still let daylight in. Snow could not accumulate on top of stair blocks, grass was able to grow on the block directly underneath a stair block, and grass wouldn't disappear if a stair block was placed on top of it. Any stair block placed in Alpha 1.2.0_02 to Beta 1.5 would keep this property in later versions until it or an adjacent block is changed or removed.
 * In Beta 1.6, the icon for stairs was reversed to show a more recognizable figure.
 * Brick Stairs and Stone Brick Stairs were added in the 1.8 Update, while Nether Brick Stairs were added in 1.9

Bugs

 * Using Stone Brick Stairs, it is possible to mine three different types of Stone Brick Blocks depending on the direction the player is facing while placing them:

Note: This bug has been fixed in Beta 1.9 and above. This bug applies to Beta 1.8.1. This is due to the stairs' damage value (representing the direction it's facing) being reused in the dropped block's damage value (representing the type of stone brick, see Data values).
 * The new stairs in Beta 1.8 used to have black in the air quarter, however this was fixed.

Trivia

 * Stone Stairs are mined in 3 seconds with a pickaxe, but 10 seconds with any other tool (or hands).
 * Placing 6 Mossy Stone Brick or 6 Cracked Stone Brick in a crafting box will only make Stone Brick Stairs not Mossy/Cracked Stone Brick Stairs.
 * Unlike slabs, different types of stairs have different data values.
