Stairs

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

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

Behavior
As of version 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.

If another block gets placed above a stair block, the stairs will revert back to one of the original building materials (fixed as of the Halloween Update). Water will not revert the block, but flow over it 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.

At some viewing angles, hovering the reticule over the stair block makes the black outline flicker. This makes mining the stair block glitchy, and the block behind it will often be mined instead. Also, stairs take a very long time to mine, even with diamond tools.

As of Alpha version 1.2.0_02, stairs have 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 will 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 do not penetrate stair blocks, making them an unusually effective material for creating roofing which keeps weather out, yet allows daylight in. Snow cannot accumulate on top of stair blocks.

Stairs are only available in the Alpha and Beta versions. If a save file containing stairs built with the alpha version is loaded into Infdev, the game will crash.
