Subject: Verify node type is facedir.
X-Git-Tag: 0.4.14~174
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=82299b94dc6f661e0b97e6f747dee8c250a70aa8;p=oweals%2Fminetest_game.git

Verify node type is facedir.

This prevents nodes that are not of the "facedir" paramtype2,
as these are generally not expected to be able to rotate. Mods
and other methods may still manipulate param2 of these nodes
as expected.
