Description

I've noticed that NPC's saving their rotation when a player leaves and rejoins a server is really inconsistant. Some NPCs from older versions of the plugin seem to have saved their rotation correctly, but my newer ones don't seem to do that and instead face their heads in the right direction but their bodies will be awkwardly rotated. I've tried setting their rotation with /lookclose, but they go back to their old rotation after I leave the server and rejoin.

Update from testing and discussion in the dev channels:

Body rotation on older versions was synchronized to the head rotation by displaying an arm-swing animation, as this would force the body to match the head clientside. The NPC's head was then rotated from there to match the saved rotation.

In 1.18.2, this appears to no longer work:

Meaning, a new solution to the issue will have to be found to correctly sync body&head yaw in modern minecraft versions.

Just updating here from a few weeks ago; Minecraft arm swing code hasn't changed, unfortunately nothing else has been added to sync / set body yaw for players.

It has been requested by another user* to have a command to link head/body rotation to the same value automatically.

Relatedly it'd also be nice to have something like a /npc moveto --body [yaw]

(* who unfortunately had to be blocked from this repo and Discord due to the inappropriate argumentative way they about it)

This issue has changed(?). Body rotation now persists, but head rotation for player NPCs always defaults to south for some reason. If you leave an NPC's active area and then load it back in, its head will face south by default.
