Previously, multiple stacks of the same item ID could overwrite data in each other because of how the logic in ContainerStore::add() works. For example, a stack of 5 grand soul gems with no souls would get added to the player, then the attempt to add a grand soul gem with a particular soul would retrieve the previous stack first before setting all of it to that soul, resulting in 6 grand soul gems with that soul.
Enchanted inventory items continuously recharge their enchantment charges, which getItemPtrFromStore() should account for.
Additionally, prevent framelistener errors caused by PlayerItemUse packets about non-existent items.
Previously, client mods adding packet-sending scripts to the spawn area made clients send the associated packets as soon as they inputted their character name when joining a server using those mods. This made the clients either get disconnected for not replying to a handshake first, or it made them get kicked for sending object packets that are disallowed for players who are not logged in.
To fix this, LocalPlayer's hasFinishedCharGen() has been replaced with isLoggedIn(), because the former was already returning true when players inputted their names.
Previously, the player's currently selected weapon was being used in ranged attacks as in the original melee-oriented attack sync, which meant that shooting one type of projectile and then equipping another while the old projectile was still in the air turned the old projectile into the new projectile upon impact.
Additionally, avoid running most of the code in MechanicsHelper::assignAttackTarget() for non-hitting melee and ranged attacks.
Projectile hits now send Attack packets with RANGED attacks, and their success or failure is now synchronized.
Strike enchantments no longer require a valid victim to be synchronized.
Additional debug messages have been added for attacks.
Whenever an item is added to or removed from the player's ContainerStore, that player sends a PlayerInventory packet with just that addition or removal.
This eliminates all the unnecessary packet spam related to oversized PlayerInventory packets that had existed in one form or another since the initial implementation of inventory sync in 1b259e2d33
Additionally, move booleans from BasePlayer to LocalPlayer when they are only needed on the client, and make the usage of the isReceivingQuickKeys boolean consistent with the new isReceivingInventory boolean by having them both in the processors of their associated packets.
For a long time, whenever a PlayerInventory packet was sent, it contained all the items in the player's inventory, because that's how Koncord originally implemented it and I always had too many other priorities to go back and rework it.
From now on, clients only send PlayerInventory packet with the one item added or removed, with the single exception being trading with merchants, where the entire inventory is still sent for the time being.
When LocalActors briefly become DedicatedActors as the result of a server script, the DedicatedActors are immediately uninitialized to avoid bugs like them jumping in place or rotating slightly.
Additionally, the playing of animations and sounds received in packets for DedicatedActors is no longer done during their next update, but is instead done instantly when the packets are received.
The variable equipmentItem is identical to currentItem, so it should not have been added in commit 58a6a8c3bc
Addditionally, use a more descriptive variable name than "a" for item Ptrs.
Players can no longer unilaterally use items on themselves in their inventory. When they try to use an item, they send a PlayerItemUse packet to the server with the item's details. A serverside script can then check the item and either send the packet back to make the item use go through or drop it.
Spell, potion, enchantment, creature, NPC, armor, book, clothing, miscellaneous and weapon record data can now be sent in a RecordDynamic packet. Additionally, the packets include data related to associated magical effects (for spells, potions and enchantments), data related to default inventory contents (for creatures and NPCs) and data related to body parts affected (for armor and clothing).
The server now has associated script functions for setting most of the details of the above, with the main exception being individual creature and NPC stats.
Records can either be created entirely from scratch or can use an existing record (set via the baseId variable) as a starting point for their values. In the latter case, only the values that are specifically set override the starting values. Creature and NPC records also have an inventoryBaseId that can be used on top of the baseId to base their inventories on another existing record.
The client's RecordHelper class has been heavily expanded to allow for the above mentioned functionality.
When players create spells, potions and enchantments as part of regular gameplay, they send RecordDynamic packets that provide the server with the complete details of the records that should be created. When they create enchantments, they also provide the server with armor, book, clothing and weapon records corresponding to the items they've enchanted.
This functionality added by this packet was originally supposed to be exclusive to the rewrite, but I've gone ahead and tried to provide it for the pre-rewrite in a way that can mostly be reused for the rewrite.
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.
