From: ANAND Date: Sat, 16 May 2020 19:42:31 +0000 (+0530) Subject: Make automatic_rotate relative, allow setting rotation (#8468) X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=c1ce4be756e2554051a27f244303377c0a7d69a6;p=oweals%2Fminetest.git Make automatic_rotate relative, allow setting rotation (#8468) automatic_rotate does not make sense if it is absolute. Make it relative. To avoid bouncing, set_rotation did not update the client when automatic_rotate was set. That's no longer necessary because the new spinning method applies the rotation on top of the current one, and the updates are necessary for set_rotation to actually transform the object.
