Previously, attempts to reuse the same reference for multiple creature disguises led to movement animation issues, as well as a dynamic_cast error in Creature::getInventoryStore() that made a DedicatedPlayer vanish completely when they first lost their creature disguise, then disguised themselves as a creature that could not hold weapons and then disguised themselves as a creature that could hold weapons.
The usage of const_cast has been replaced with usage of MWWorld::getModifiableStore() and ESMStore::overrideRecord()
Methods whose names started with "update" now start with "override", for consistency with ESMStore's overrideRecord()
New methods have been added for "overriding" enchantment, potion and spell records, which actually leads to them being created with their already set refIds if they haven't been created yet, as per the description of ESMStore::overrideRecord(): "Insert a record with set ID, and allow it to override a pre-existing static record."
Usage of RecordHelper methods has been updated in DedicatedPlayer.
Actors who are on the ground have their inertial force ignored, so they are now made to not be regarded as being on the ground in World::setInertialForce()
I originally added rotation animation sync as part of commit 068a45be87. Unfortunately, it meant the PlayerPosition packets were now twice as large as they had been before, which was less than ideal for such a frequently sent packet, which is why Koncord switched to a more optimized approach in commits 5f30dfd5db and d67db1a9bd.
Recently, there have since been some rotation animation problems in OpenMW, which have broken the way Koncord's approach looks. My original approach still looks somewhat okay, so I'm switching back to it until we can figure out how to reuse it under the current circumstances.
Although weather sync was added by Koncord to the rewrite in fd721143e2 in a way that used surprisingly few lines of code, it relied on the server requesting weather states every second from authority players and sending them to non-authority players, while also allowing only very sudden weather transitions across regions, i.e. if there was one player in the Ascadian Isles who had stormy weather, and another player with clear weather in the Bitter Coast Region walked across to the Ascadian Isles, that player was instantly made to have stormy weather with no kind of transition at all.
My approach solves both of those problems. It solves the packet spam by only sending weather updates to the server when weather changes happen or when there are new arrivals to a weather authority's region, and it allows for both sudden weather transitions when players teleport to a region and for soft, gradual transitions when players walk across to a region. It is inspired by my previous actor sync, and uses a WorldRegionAuthority packet to set players as region authorities in a similar way to how ActorAuthority sets players as cell AI authorities. Weather changes are created only by the region authority for a given region, and weather packets are also only sent by that authority.
However, it should be noted that gradual weather transitions are used by default in this implementation. To use sudden weather transitions, the serverside Lua scripts need to forward WorldWeather packets with the forceWeather boolean set to true. That is, however, already handled by our default Lua scripts in situations where it makes sense.
