Stairs is a simple mod that adds 170 new stair blocks to the game (including 2 technical stair blocks). Combined with Mojang's 14 stairs that's 184 stairs!
The stairs are not only for added cosmetics in your detailed builds, but most of them have the same functionality as their base block (crafting table stairs can be crafted on, sand stairs fall with gravity, glowstone stairs light up, redstone lamp stairs can turn on/off with redstone signal, restone stairs emit a redstone signal, etc). Some notable exceptions are
TNT stairs will not blow up (now blow up in b16+), and ore stairs will drop the stair block instead of the ore, etc.
I've done my best to include every possible stair type that makes sense in this mod. Some blocks not included are things like pistons, anything with an inventory (except crafting table), the structure and command blocks, etc. If you have a need for a stair type that isn't in this mod please let me know and I will see what I can do about adding it in.
* Ruby and Ruby Ore stairs seen in picture are part of Pl3xRubies mod. They are shown as an example that outside mods can hook in and add their own stairs.
All stairs are added to a new Stairs tab, including the vanilla stairs for convenience.
Do I see a slabs and vertical slabs tab? Is that a sneak peek at more mods to come? :O
