To place stairs, use a stairs item while pointing at a surface facing the space the stairs should occupy. Stairs will place 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 will place the stairs right side up. Pointing at a block bottom or the top half of a block side will place the stairs upside-down. Stairs will 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 will wrap 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 will shorten to join only the other stairs' full-block side (it creates an "outer corner"). Right side up stairs won't join with upside-down stairs and vice versa. Page added by Nitoblock
