paramtype2 == "facedir"
^ The rotation of the node is stored in param2. Furnaces and chests are
rotated this way. Can be made by using minetest.dir_to_facedir().
Values range 0 - 23
facedir modulo 4 = axisdir
0 = y+ 1 = z+ 2 = z- 3 = x+ 4 = x- 5 = y-
facedir's two less significant bits are rotation around the axis
Nodes can also contain extra data. See "Node Metadata".
