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. Stairs naturally occur in NPC villages.

Crafting
Stairs can be made from six wooden planks, six cobblestone, six bricks or six Stone Brick, producing four stairs per craft. Upon destroying the block after placement, it will yield only one of the original material.

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.

There is a currently known bug where the top of a brick stair is black due to a lighting error. It is visible in the 1.8 Pre-Release.

Trivia

 * Placing a block of stairs on top of a chest does not prevent the chest from being opened.
 * Stone Stairs will be "harvested" in 3 seconds with a pickaxe, but 12 seconds with any other tool (or hands).
 * Contrary to their intended function, Blocks of Stairs are sometimes used by player to make aesthetically pleasing "sloped" roofs for their buildings.

Glitches
There is a glitch where when stairs are placed at the water's edge,(with the top edge of the block at the water's level) Any boat going at any speed can collide with it with no damage to the boat, making it ideal for the creation of a dock.

History



 * At some viewing angles, hovering the cursor over the stair block would 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, however nothing else to the properties of stairs was changed.
 * There will be new types of stairs in the upcoming Adventure Update.

Future
In Minecraft 1.8 at least two new types of stairs will appear.
