Equipment: removed the visibleItemLayoutVerified_ gate from
updateOtherPlayerVisibleItems(). The default WotLK field layout (base=284,
stride=2) is correct and should be used immediately. The verification
heuristic was silently blocking ALL other-player equipment rendering by
queuing for auto-inspect (which doesn't return items in WotLK anyway).
Follow: auto-follow now uses run speed (autoRunning) instead of walk speed.
Also uses squared distance for the distance checks.
Commands: /quit, /exit aliases for /logout; /difficulty normal/heroic/25/25heroic
sends CMSG_CHANGEPLAYER_DIFFICULTY.
Inspect: CMSG_INSPECT was writing full uint64 GUID instead of packed GUID.
Server silently rejected the malformed packet. Fixed both InspectPacket and
QueryInspectAchievementsPacket to use writePackedGuid().
Follow: was a no-op (only stored GUID). Added client-side auto-follow system:
camera controller walks toward followed entity, faces target, cancels on
WASD/mouse input, stops within 3 units, cancels at 40+ units distance.
Party commands:
- /lootmethod (ffa/roundrobin/master/group/nbg) sends CMSG_LOOT_METHOD
- /lootthreshold (0-5 or quality name) sets minimum loot quality
- /raidconvert converts party to raid (leader only)
Equipment diagnostic logging still active for debugging naked players.
Mail: change money/COD fields from uint32 to uint64 in CMSG_SEND_MAIL and
SMSG_MAIL_LIST_RESULT for WotLK 3.3.5a. Classic keeps uint32 on the wire.
Fixes money truncation and packet misalignment causing mail failures.
Other-player capes: add cape texture loading to setOnlinePlayerEquipment().
The cape geoset was enabled but no texture was loaded, leaving capes blank.
Now mirrors the local-player path: looks up ItemDisplayInfo.dbc, finds cape
texture candidates, applies via setGroupTextureOverride/setTextureSlotOverride.
Zone toasts: suppress duplicate zone toast when the zone text overlay is
already showing the same zone name. Fixes double "Entering: Stormwind City".
Network: enable TCP_NODELAY on both auth and world sockets after connect(),
disabling Nagle's algorithm to eliminate up to 200ms buffering delay on
small packets (movement, spell casts, chat).
Rendering: track material and bone descriptor sets in M2 renderer to skip
redundant vkCmdBindDescriptorSets calls between batches sharing same textures.
- Replace count()+operator[] double lookups with find() or try_emplace()
in gameObjectInstances_, playerTextureSlotsByModelId_, onlinePlayerAppearance_
- Add Entity::isUnit() helper; replace 5 dynamic_cast<Unit*> in per-frame
UI rendering (nameplates, combat text, pet frame) with isUnit()+static_cast
- Add constexpr kInv255 reciprocal for per-pixel normal map generation loops
in character_renderer and wmo_renderer
Spline parsing: remove Classic format fallback from the WotLK parser. The
PacketParsers hierarchy already dispatches to expansion-specific parsers
(Classic/TBC/WotLK/Turtle), so the WotLK parseMovementBlock should only
attempt WotLK spline format. The Classic fallback could false-positive when
durationMod bytes resembled a valid point count, corrupting downstream parsing.
Preload DBC caches: call loadSpellNameCache() and 5 other lazy DBC caches
during handleLoginVerifyWorld() on initial world entry. This moves the ~170ms
Spell.csv load from the first SMSG_SPELL_GO handler to the loading screen,
eliminating the mid-gameplay stall.
WMO portal culling: move per-instance portalVisibleGroups vector and
portalVisibleGroupSet to reusable member variables, eliminating heap
allocations per WMO instance per frame.
Spline auto-detection: try WotLK format before Classic to prevent false-positive
matches where durationMod float bytes resemble a valid Classic pointCount. This
caused the movement block to consume wrong byte count, corrupting the update mask
read (maskBlockCount=57/129/203 instead of ~5) and silently dropping NPC spawns.
Terrain latency: bound WMO liquid group loading to 4 groups per advanceFinalization
call. Large WMOs (e.g., Stormwind canals with 40+ liquid groups) previously loaded
all groups in one unbounded loop, blowing past the 8ms frame budget and causing
stalls up to 1300ms. Now yields back to processReadyTiles() after 4 groups so the
time budget check can break out.
- Hoist DBC field index lookups before loops in game_handler (7 DBC iteration loops)
- Cache getSkybox()/getPosition() calls instead of redundant per-frame queries
- Merge textureHasAlphaByPtr_ + textureColorKeyBlackByPtr_ into single map
- Add constexpr for DEG_TO_RAD, reciprocal constants, physics delta
- Add reserve() for WMO/M2 collision grid queries and portal BFS
- Frustum plane normalize: inversesqrt instead of length+divide
- M2 particle emission: inversesqrt for direction normalization
- Parse creature display IDs from query response
- UI: show spell names/IDs as fallback instead of "Unknown"
Squared distance optimizations across 30 files:
- Convert glm::length() comparisons to glm::dot() (no sqrt)
- Use glm::inversesqrt() for check-then-normalize patterns (1 rsqrt vs 2 sqrt)
- Defer sqrt to after early-out checks in collision/movement code
- Hottest paths: camera_controller (21), weather particles, WMO collision,
transport movement, creature interpolation, nameplate culling
Container and algorithm improvements:
- std::map<string> → std::unordered_map for asset/DBC/MPQ/warden caches
- std::mutex → std::shared_mutex for asset_manager and mpq_manager caches
- std::sort → std::partial_sort in lighting_manager (top-2 of N volumes)
- Double-lookup find()+operator[] → insert_or_assign in game_handler
- Add reserve() for per-frame vectors: weather, swim_effects, WMO/M2 collision
Threading and synchronization:
- Replace 1ms busy-wait polling with condition_variable in character_renderer
- Move timestamp capture before mutex in logger
- Use memory_order_acquire/release for normal map completion signaling
API additions:
- DBC getStringView()/getStringViewByOffset() for zero-copy string access
- Parse creature display IDs from SMSG_CREATURE_QUERY_SINGLE_RESPONSE
Add [[nodiscard]] to VkShaderModule::loadFromFile, Shader::loadFromFile/
loadFromSource, AssetManifest::load, DbcLoader::load — all return bool
indicating success/failure that callers should check.
Suppress with (void) at 17 call sites where validity is checked via
isValid() after loading rather than the return value (m2_renderer
recreatePipelines, swim_effects recreatePipelines).
Add kCastGreen (interruptible cast bar, 5 uses) and kQueueGreen
(queue status / talent met, 7 uses across game_screen + talent_screen).
Remove commented-out renderQuestMarkers call (replaced by 3D billboards).
The findMemType/findMemoryType helper in auth_screen, loading_screen,
and vk_context returned 0 on failure — a valid memory type index.
Changed to return UINT32_MAX and log an error, so vkAllocateMemory
receives an invalid index and fails cleanly rather than silently
using the wrong memory type.
Add [[nodiscard]] to VkBuffer::uploadToGPU/createMapped and
VkContext::initialize/recreateSwapchain so callers that ignore
failure are flagged at compile time. Suppress with (void) cast at
3 call sites where failure is non-actionable (resize best-effort).
- Move itemKeys/spellKeys/thrKeys to shared kItemSetItemKeys/
kItemSetSpellKeys/kItemSetThresholdKeys in ui_colors.hpp, removing
5 identical local definitions across game_screen and inventory_screen
- Widen totem timer snprintf buffer from 8 to 16 bytes (defensive)
- Promote kStatTooltips to constexpr
Deduplicate class/race bitmask arrays (3 copies each → 1 shared) and
socket type definitions (3 copies → 1 shared). Eliminates ~80 lines of
repeated struct definitions across game_screen.cpp and inventory_screen.cpp.
Add kDarkRed, kSoftRed, kHostileRed, kMediumGray to ui_colors.hpp and
replace 31 inline ImVec4 literals across game_screen, character_screen,
inventory_screen, and performance_hud. Also replace local color aliases
in performance_hud with shared constants.
- Add kBrightGold, kPaleRed, kBrightRed, kLightBlue, kManaBlue, kCyan to ui_colors.hpp
- Replace 61 inline ImVec4 color literals across game_screen, inventory_screen,
talent_screen, and world_map with named constants
- Remove const_cast in character_renderer render loop by using non-const iteration
Add colors::kTooltipGold to ui_colors.hpp and replace 14 inline
ImVec4(1.0f, 0.82f, 0.0f, 1.0f) literals in inventory_screen.cpp
for item set names, unique markers, and quest item indicators.
Add getInventorySlotName() and renderBindingType() to ui_colors.hpp,
replacing 3 copies of the 26-case slot name switch (2 inventory_screen
+ 1 game_screen) and 2 copies of the binding type switch. Removes ~80
lines of duplicate tooltip code.
Extract getEnchantmentNames() to share a single SpellItemEnchantment.dbc
cache between both renderItemTooltip overloads, replacing two identical
19-line lazy-load blocks with single-line references.
Extract renderSettingsInterfaceTab() (108 lines) from
renderSettingsWindow(). 6 of 7 tabs now have dedicated methods;
only Video remains inline (shares init state with parent).
Extract renderSettingsGameplayTab() (162 lines) and
renderSettingsControlsTab() (96 lines) from renderSettingsWindow().
5 of 7 settings tabs are now in dedicated methods; only Video and
Interface remain inline (they share resolution/display local state).
Extract renderSettingsAudioTab() (110 lines), renderSettingsChatTab()
(49 lines), and renderSettingsAboutTab() (48 lines) from the 1013-line
renderSettingsWindow(). Reduces it to ~806 lines.
Move 98 lines of auto-attack leash range, melee resync, facing
alignment, and hostile attacker orientation into a dedicated method.
update() is now ~180 lines (74% reduction from original 704).
Move 131 lines of taxi flight detection, mount reconciliation, taxi
activation timeout, and flight recovery into a dedicated method.
update() is now ~277 lines (61% reduction from original 704).
Move entity movement interpolation loop (distance-culled per-entity
update) into its own method. update() is now ~406 lines (down from
original 704, a 42% reduction across 3 extractions).
Move 164 lines of timer/pending-state logic into updateTimers():
auction delay, quest accept timeouts, money delta, GO loot retries,
name query resync, loot money notifications, auto-inspect throttling.
update() is now ~430 lines (down from original 704).
Move socket update, packet processing, Warden async drain, RX silence
detection, disconnect handling, and Warden gate logging into a separate
updateNetworking() method. Reduces update() from ~704 to ~591 lines.
Add registerWorldHandler() that wraps handler calls with an IN_WORLD
state check. Replaces 8 state-guarded lambda dispatch entries with
concise one-line registrations.
Add registerHandler() using member function pointers, replacing 120
single-line lambda dispatch entries of the form
[this](Packet& p) { handleFoo(p); } with concise
registerHandler(Opcode::X, &GameHandler::handleFoo) calls.
Add helpers for common dispatch table patterns: registerSkipHandler()
for opcodes that just discard data (14 sites), registerErrorHandler()
for opcodes that show an error message (3 sites). Reduces boilerplate
in registerOpcodeHandlers().
Extract shared M2+skin loading logic into Application::loadWeaponM2(),
replacing duplicate 15-line blocks in loadEquippedWeapons() and
tryAttachCreatureVirtualWeapons(). Future weapon loading changes only
need to update one place.
Add writePackedGuid() to Packet class for read/write symmetry. Remove
now-redundant UpdateObjectParser::readPackedGuid and
MovementPacket::writePackedGuid static methods. Replace 6 internal
readPackedGuid calls, 9 writePackedGuid calls, and 1 inline 14-line
transport GUID write with Packet method calls.
Move packed GUID reading into Packet class alongside readUInt8/readFloat.
Replace 121 UpdateObjectParser::readPackedGuid(packet) calls with
packet.readPackedGuid() across 4 files, reducing coupling between
Packet and UpdateObjectParser.
Add GameHandler::withSoundManager() that encapsulates the repeated
getInstance()->getRenderer()->getSoundManager() null-check chain.
Replace 6 call sites, with helper available for future consolidation
of remaining 25 sites.
Mark spellNameCache_, titleNameCache_, factionNameCache_, areaNameCache_,
mapNameCache_, lfgDungeonNameCache_ and their loaded flags as mutable.
Update 6 lazy-load methods to const. Removes all 13 const_cast<GameHandler*>
calls, allowing const getters to lazily populate caches without UB.
Add GameHandler::getUnitByGuid() that combines entityManager.getEntity()
with dynamic_cast<Unit*>. Replaces 10 two-line lookup+cast blocks with
single-line calls.
Add renderCoinsFromCopper(uint64_t) overload in ui_colors.hpp that
decomposes copper into gold/silver/copper and renders. Replace 14
manual 3-line decomposition blocks across game_screen and
inventory_screen with single-line calls.
Add Packet::hasFullPackedGuid() method and remove identical standalone
definitions from game_handler.cpp and packet_parsers_classic.cpp.
Replace 53 free-function calls with method calls.
Add getRemainingSize() one-liner to Packet class and replace all 656
instances of getSize()-getReadPos() across game_handler, world_packets,
and both packet parser files.
Create shared include/ui/ui_colors.hpp with common ImGui color constants,
item quality color lookup, and renderCoinsText utility. Remove 3 duplicate
renderCoinsText implementations and 3 duplicate quality color switch
blocks across game_screen, inventory_screen, and quest_log_screen.
