Previously SMSG_SPELL_DELAYED only adjusted the local player's cast bar.
Now it also extends unitCastStates_ for any non-player caster (e.g.
boss cast bar extends correctly when hit by a tank during cast).
- Handle MSG_CHANNEL_START: populate unitCastStates_ for both the local
player and any non-player caster (boss/mob channeled spells); use
full uint64 GUIDs for TBC/Classic, packed GUIDs for WotLK
- Handle MSG_CHANNEL_UPDATE: sync remaining channel time; clear cast
state on channel completion (remainingMs == 0)
- Fix SMSG_RESUME_CAST_BAR: also resumes non-player units' cast bars
(previously only resumed the player's own bar after zone transitions)
- Add party member cast bars in renderPartyFrames: golden progress bar
appears beneath the power bar when a party member is casting,
leveraging the existing unitCastStates_ per-GUID map
WotLK uses packed GUIDs in SMSG_SPELL_FAILURE / SMSG_SPELL_FAILED_OTHER.
TBC 2.4.3 and Classic 1.12 use full uint64 GUIDs. The previous fix used
UpdateObjectParser::readPackedGuid for all expansions, which would
mis-parse the caster GUID on TBC/Classic servers, leaving stale cast
bars and potentially corrupting subsequent packet reads.
Now checks isClassicLikeExpansion() || isActiveExpansion("tbc") and
reads a raw uint64 for those expansions, matching the TBC/Classic wire
format used in parseSpellStart/parseSpellGo overrides.
When a spell fails or is interrupted, the server sends SMSG_SPELL_FAILURE
(for the caster's own POV) or SMSG_SPELL_FAILED_OTHER (for observers).
Previously these were consumed without updating cast state, leaving stale
cast bars for interrupted enemies. Now:
- SMSG_SPELL_FAILURE: erases unitCastStates_[failGuid] for non-player
casters (still clears player casting/currentCastSpellId for own casts)
- SMSG_SPELL_FAILED_OTHER: erases unitCastStates_[guid] for the caster
so boss/enemy cast bars immediately clear on interrupt/kick
Previously the target cast bar tracked a single target using 4 private
fields. This replaces that with unitCastStates_ (unordered_map<uint64_t,
UnitCastState>), tracking cast state for every non-player unit whose
SMSG_SPELL_START we receive.
Changes:
- GameHandler::UnitCastState struct: casting, spellId, timeRemaining,
timeTotal
- getUnitCastState(guid) → returns cast state for any tracked unit
- isTargetCasting(), getTargetCastSpellId(), getTargetCastProgress(),
getTargetCastTimeRemaining() now delegate to getUnitCastState(targetGuid)
- handleSpellStart: tracks all non-player casters (not just the target)
- handleSpellGo: erases caster from map when spell lands
- update loop: ticks down all unit cast states, erasing expired entries
- unitCastStates_ cleared on world reset
- renderBossFrames: shows red cast progress bar per boss slot with
spell name + remaining seconds — critical for instance interrupt play
Adds 5 gold/grey dot indicators below the power bar in the player frame
for Rogue (class 4) and Druid (class 11), showing the current combo
point count from SMSG_UPDATE_COMBO_POINTS. Active points are bright gold;
empty slots are dark grey. Dots are centered in the frame width.
The display is always shown for Rogues; for Druids it only appears when
combo points are non-zero (they only accumulate in Cat Form).
SMSG_SPELL_START fires for all units, not just the player. Previously only
the player's own cast was tracked; now we also track when the current
target is casting, enabling interrupt decisions.
- GameHandler: track targetCasting_/targetCastSpellId_/targetCastTimeTotal_
/targetCastTimeRemaining_ — updated by SMSG_SPELL_START for the current
target and ticked down in the update loop each frame
- Target cast cleared when: target changes (setTarget), target's spell
lands (SMSG_SPELL_GO), or cast timer expires naturally
- game_screen: renderTargetFrame shows a red cast progress bar between
the power bar and distance line when the target is casting, with
spell name + remaining seconds
- Public accessors: isTargetCasting(), getTargetCastSpellId(),
getTargetCastProgress(), getTargetCastTimeRemaining()
Both SpellGoParser::parse (WotLK) and TbcPacketParsers::parseSpellGo
(TBC) read missCount but did not consume the per-miss (guid + missType)
entries that follow, leaving unread bytes in the packet and silently
corrupting any subsequent parsing of cast-flags–gated spell data.
- Add SpellGoMissEntry{targetGuid, missType} and missTargets vector
to SpellGoData
- WotLK parser now reads packed GUIDs + missType per miss entry
- TBC parser now reads full uint64 GUIDs + missType per miss entry
(9 bytes per entry, bounds-checked)
- handleSpellGo now shows MISS/DODGE/PARRY/BLOCK combat text
for each missed target when the local player cast the spell,
complementing the existing SMSG_SPELLLOGMISS path
- Remove unused foliageLikeModel variable in m2_renderer pass-2 loop
(fix unused-variable warning)
- Update smoke model comment in m2_renderer to reflect current state
SMSG_PET_SPELLS: Parse full packet — pet GUID, react/command state,
10 action bar slots, per-spell entries with autocast flags. Previously
only read the GUID.
SMSG_PET_MODE: Parse petGuid + mode uint32 (command low byte, react
high byte) to keep stance state in sync after server updates.
SMSG_PET_BROKEN: Clear pet state and show "Your pet has died." chat
message.
SMSG_PET_LEARNED_SPELL / SMSG_PET_UNLEARNED_SPELL: Maintain pet spell
list incrementally.
SMSG_PET_CAST_FAILED: Parse and log cast count + spell + reason.
New state accessors: getPetActionSlot(), getPetCommand(), getPetReact(),
getPetSpells(), isPetSpellAutocast().
CMSG_PET_ACTION: Add targetGuid (uint64) field — the wire format
requires petGuid(8)+action(4)+targetGuid(8). Was sending an 12-byte
packet instead of the required 20 bytes.
sendPetAction(): New method that builds and sends CMSG_PET_ACTION with
the correct target guid.
switchTalentSpec() was only updating local state without notifying the
server, leaving the server out of sync with the client's active talent
group. Now sends CMSG_SET_ACTIVE_TALENT_GROUP_OBSOLETE (WotLK wire
opcode 0x4C3) with the target group index (0=primary, 1=secondary),
prompting the server to apply the spec swap and respond with a fresh
SMSG_TALENTS_INFO for the newly active group.
Also adds ActivateTalentGroupPacket::build() to world_packets for the
packet construction.
The SMSG_LFG_PLAYER_REWARD handler was printing raw copper value with
a "g" suffix (e.g. "12345g") instead of converting to gold/silver/copper.
Now formats as "1g 23s 45c" matching the standard WoW convention.
Renders a compact top-centre overlay showing Alliance vs Horde scores
when the player is in a recognised battleground map. Score values are
read directly from the world state map maintained by SMSG_INIT_WORLD_STATES
and SMSG_UPDATE_WORLD_STATE, so no extra server packets are needed.
Supported maps:
489 – Warsong Gulch (flag captures, max 3)
529 – Arathi Basin (resources, max 1600)
30 – Alterac Valley (reinforcements, max 600)
566 – Eye of the Storm (resources, max 1600)
607 – Strand of Ancients
TBC 2.4.3 and Classic 1.12 send resetTime as uint32 (seconds) with no
extended byte, while WotLK 3.3.5a sends uint64 timestamp + extended byte.
Parse the correct field widths based on expansion to prevent corrupted
instance lockout data on TBC/Classic realms.
When a player releases spirit, the server sends SMSG_DEATH_RELEASE_LOC
with the corpse map and position. Store this so the ghost can reclaim.
New flow:
- SMSG_DEATH_RELEASE_LOC now stores corpseMapId_/corpseX_/Y_/Z_ instead
of logging and discarding
- canReclaimCorpse(): true when ghost is on same map within 40 yards of
stored corpse position
- reclaimCorpse(): sends CMSG_RECLAIM_CORPSE (no payload)
- renderReclaimCorpseButton(): shows "Resurrect from Corpse" button at
bottom-center when canReclaimCorpse() is true
Two bugs fixed:
1. acceptResurrect() was always sending CMSG_SPIRIT_HEALER_ACTIVATE even
for player-cast resurrections (Priest/Paladin/Druid). That opcode is
only the correct response to SMSG_SPIRIT_HEALER_CONFIRM. For
SMSG_RESURRECT_REQUEST the server expects CMSG_RESURRECT_RESPONSE
with accept=1. Added resurrectIsSpiritHealer_ to track which path
triggered the dialog and send the right packet per type.
2. The resurrect dialog showed a generic "Return to life?" string
regardless of who cast the resurrection. Parse the optional CString
name from SMSG_RESURRECT_REQUEST (or fall back to playerNameCache)
and display "X wishes to resurrect you." when the caster is known.
TBC 2.4.3 does not have SMSG_AURA_UPDATE (added in WotLK). Instead it
uses SMSG_INIT_EXTRA_AURA_INFO_OBSOLETE (0x3A3) for full aura refresh
on login/zone and SMSG_SET_EXTRA_AURA_INFO_OBSOLETE (0x3A4) for single-
slot updates. Implement handlers for both packets so TBC buff/debuff bars
populate correctly.
Also implement SMSG_CLEAR_EXTRA_AURA_INFO (0x3A6) to remove individual
aura slots when buffs expire or are cancelled server-side.
Format parsed: uint64 targetGuid + uint8 count + per-slot {uint8 slot,
uint32 spellId, uint8 effectIndex, uint8 flags, uint32 durationMs,
uint32 maxDurationMs}. Infinite auras (0xFFFFFFFF) stored as durationMs=-1.
Single shadow depth image shared across MAX_FRAMES=2 in-flight GPU frames
caused a race: frame N's main pass reads shadow map while frame N+1's
shadow pass clears and writes it, producing visible flashing standing
still and while moving.
Fix: give each in-flight frame its own VkImage, VmaAllocation, VkImageView,
and VkFramebuffer for the shadow depth attachment. renderShadowPass() now
indexes all shadow resources by getCurrentFrame(), and layout transitions
track per-frame state in shadowDepthLayout_[frame]. Cleanup loops over
MAX_FRAMES=2. Descriptor sets already written per-frame; updated shadow
image view binding to use the matching per-frame view.
TBC 2.4.3 quest log update fields use 4 fields per slot
(questId, state, counts, timer) vs WotLK's 5 (extra counts field).
The wrong stride (5) caused all quest log reads to use wrong indices
beyond the first slot, breaking quest tracking on TBC servers.
TBC 2.4.3 CMSG_QUESTGIVER_QUERY_QUEST is guid(8) + questId(4) = 12
bytes. WotLK added a trailing isDialogContinued(u8) byte that TBC
servers don't expect; sending it caused quest details to not be sent
back on some emulators.
When the player starts casting Hearthstone (spell IDs 6948/8690),
trigger background terrain loading at the bind point so tiles are
ready when the teleport fires.
- Add HearthstonePreloadCallback to GameHandler, called from
handleSpellStart when a Hearthstone cast begins.
- Application callback enqueues a 5×5 tile grid around the bind
point via precacheTiles() (same-map) or starts a file-cache warm
via startWorldPreload() (cross-map) during the ~10 s cast time.
- On same-map teleport arrival, call processAllReadyTiles() to
GPU-upload any tiles that finished parsing during the cast before
the first frame at the new position.
Fixes: player landing in unloaded terrain and falling after Hearthstone.
TBC 2.4.3 SMSG_SPELL_START and SMSG_SPELL_GO send full uint64 GUIDs for
casterGuid/casterUnit and hit targets. WotLK uses packed (variable-length)
GUIDs. Using readPackedGuid() on a full uint64 reads the first byte as the
bitmask, consuming 1-8 wrong bytes, which shifts all subsequent fields
(spellId, castFlags, castTime) and causes:
- Cast bar to never show for the player's own spells
- Sound effects to use the wrong spell ID
- Hit/miss target tracking to be completely wrong
Additionally, TBC SMSG_SPELL_GO lacks the WotLK timestamp field after
castFlags.
Add TbcPacketParsers::parseSpellStart and ::parseSpellGo using full GUIDs,
add virtual base methods, and route both handlers through virtual dispatch.
TBC 2.4.3 SMSG_CAST_RESULT sends spellId(u32) + result(u8) = 5 bytes.
WotLK 3.3.5a added a castCount(u8) prefix making it 6 bytes. Without
this fix the WotLK parser was reading spellId[0] as castCount, then the
remaining 3 spellId bytes plus result byte as spellId (wrong), and then
whatever follows as result — producing incorrect failure messages and
potentially not clearing the cast bar on TBC.
Add TbcPacketParsers::parseCastResult override and a virtual base method,
then route SMSG_CAST_RESULT through virtual dispatch in the game handler.
Classic 1.12 SMSG_CREATURE_QUERY_RESPONSE has no iconName CString between
subName and typeFlags. The TBC/WotLK parser was reading the typeFlags
uint32 bytes as the iconName string, then reading the remaining bytes as
typeFlags — producing garbage creature type/family/rank values and
corrupting target frame display for all creatures on Classic servers.
Add ClassicPacketParsers::parseCreatureQueryResponse without the iconName
read, and route the game handler through virtual dispatch so the override
is called.
AuraUpdateParser and InitialSpellsParser were called as static functions
in the game handler, bypassing the expansion-specific overrides added to
TbcPacketParsers. Switch them to packetParsers_->parseAuraUpdate() and
packetParsers_->parseInitialSpells() so TBC 2.4.3 servers get the correct
parser for each.
Add TbcPacketParsers::parseSpellHealLog override using full uint64 GUIDs
(TBC) instead of packed GUIDs (WotLK). Route handleAttackerStateUpdate,
handleSpellDamageLog, and handleSpellHealLog through the virtual
packetParsers_ interface so expansion-specific overrides are actually
called. Previously the game handler bypassed virtual dispatch with
direct static parser calls, making all three TBC overrides dead code.
TBC 2.4.3 SMSG_ATTACKERSTATEUPDATE and SMSG_SPELLNONMELEEDAMAGELOG send
full uint64 GUIDs for attacker/target, while WotLK 3.3.5a uses packed
(variable-length) GUIDs. Using the WotLK reader on TBC packets consumes
1-8 bytes where a fixed 8 are expected, shifting all subsequent reads
and producing completely wrong damage/absorbed/resisted values.
Add TbcPacketParsers overrides that read plain uint64 GUIDs. Also note
that TBC SMSG_SPELLNONMELEEDAMAGELOG lacks the WotLK overkill field.
TBC 2.4.3 differs from WotLK in four ways:
- Header: uint8 count only (WotLK: uint32 totalCount + uint8 shownCount),
so the WotLK parser was reading 4 garbage bytes before the count
- No extra unknown uint32 between itemTextId and stationery in each entry
- Attachment item GUID: full uint64 (WotLK uses uint32 low GUID)
- Attachment enchants: 7 × uint32 id only (WotLK: 7 × {id+duration+charges})
The resulting mis-parse would scramble subject/money/cod/flags for every
mail entry and corrupt all attachment reads. Add TbcPacketParsers::parseMailList
with the correct TBC 2.4.3 format.
Read the ambient color from the MOHD chunk (BGRA uint32) and store it
on WMOModel as a normalized RGB vec3. Pass it through ModelData into
the per-batch WMOMaterialUBO (replacing the unused pad[3] bytes, keeping
the struct at 64 bytes). The GLSL interior branch now floors vertex
colors against the WMO ambient instead of a hardcoded 0.5, so dungeon
interiors respect the artist-specified ambient tint from the WMO root
rather than always clamping to grey.
SMSG_GOSSIP_MESSAGE quest entries in TBC 2.4.3 do not include
questFlags(u32) or isRepeatable(u8) that WotLK 3.3.5a added.
The WotLK default parser reads these 5 bytes, causing all quest titles
in gossip dialogs to be shifted/corrupted on TBC servers.
Add TbcPacketParsers::parseGossipMessage() which parses quest entries
without those fields, fixing NPC quest list display.
CMSG_CAST_SPELL: WotLK adds a castFlags(u8) byte after spellId that TBC
2.4.3 does not have. Add TbcPacketParsers::buildCastSpell() to omit it,
preventing every spell cast from being rejected by TBC servers.
CMSG_USE_ITEM: WotLK adds a glyphIndex(u32) field between itemGuid and
castFlags that TBC 2.4.3 does not have. Add buildUseItem() override.
SMSG_MONSTER_MOVE: WotLK adds a uint8 unk byte after the packed GUID
(MOVEMENTFLAG2_UNK7 toggle) that TBC 2.4.3 does not have. Add
parseMonsterMove() override to fix NPC movement parsing — without this,
all NPC positions, durations, and waypoints parse from the wrong byte
offset, making all NPC movement appear broken on TBC servers.
Add AudioEngine::playSound2DStoppable() + stopSound() so callers can
hold a handle and cancel playback early. SpellSoundManager::playPrecast()
now stores the handle in activePrecastId_; stopPrecast() cuts the sound.
playCast() calls stopPrecast() before playing the release sound, so the
channeling audio never bleeds past cast time. SMSG_SPELL_FAILURE and
SMSG_CAST_FAILED both call stopPrecast() so interrupted casts silence
immediately.
Hang/GPU device lost fix:
- M2_INSTANCES and WMO_INSTANCES finalization phases now create instances
incrementally (32 per step / 4 per step) instead of all at once, eliminating
the >1s main-thread stalls that caused GPU fence timeouts and device loss
M2 two-pass transparent rendering:
- Opaque/alpha-test batches render in pass 1, transparent/additive in pass 2
(back-to-front sorted) to fix wing transparency showing terrain instead of
trees — adds hasTransparentBatches flag to skip models with no transparency
Tile streaming improvements:
- Sort new load queue entries nearest-first so critical tiles load before
distant ones during fast taxi flight
- Increase taxi load radius 6→8 tiles, unload 9→12 for better coverage
Water refraction gated on FSR:
- Disable water refraction when FSR is not active (bugged without upscaling)
- Auto-disable refraction if FSR is turned off while refraction was on
SMSG_LOOT_LIST, SMSG_COMPLAIN_RESULT, SMSG_ITEM_REFUND_INFO_RESPONSE,
and SMSG_ITEM_ENCHANT_TIME_UPDATE were incorrectly falling through to the
SMSG_RESUME_CAST_BAR handler, causing those packets to be parsed as
cast bar resume data with a completely different wire format.
- Parse uint64 killerGuid + uint64 victimGuid
- Resolve names from playerNameCache (players) and entity manager (NPCs)
- Show "[Killer] killed [Victim]." as system chat when both names are known
- Parse uint8 itemClass + uint32 subClassMask from SMSG_SET_PROFICIENCY
- Store weaponProficiency_ (itemClass=2) and armorProficiency_ (itemClass=4)
- Expose getWeaponProficiency(), getArmorProficiency(), canUseWeaponSubclass(n),
canUseArmorSubclass(n) on GameHandler for use by equipment UI
- Enables future equipment slot validation (grey out non-proficient items)
- SMSG_SPELLDISPELLOG: parse packed caster/victim + dispel spell + isStolen +
dispelled spell list; show system message when player dispels or has a buff
dispelled/stolen (e.g. "Shadow Word: Pain was dispelled." / "You dispelled Renew.")
- SMSG_SPELLSTEALLOG: separated from SPELLDISPELLOG consume group with comment
explaining the relationship (same wire format, player-facing covered by SPELLDISPELLOG)
- SMSG_SPELLDAMAGESHIELD: parse victim/caster/damage fields and show SPELL_DAMAGE
combat text for player-relevant events (damage shields like Thorns)
- SMSG_SPELLORDAMAGE_IMMUNE: parse packed caster/victim guids and show new
IMMUNE combat text type when player is involved in an immunity event
- Add CombatTextEntry::IMMUNE type to spell_defines.hpp and render it as
white "Immune!" in the combat text overlay
- handleCompressedMoves: add MSG_MOVE_* routing so SMSG_MULTIPLE_MOVES
sub-packets (player movement batches) are dispatched to handleOtherPlayerMovement
instead of logged as unhandled; fix runtime-opcode lookup (non-static array)
Socket fixes (fixes Windows-only connection failure):
- WorldSocket::connect() now waits for non-blocking connect to complete with
select() before returning, preventing WSAENOTCONN on the first recv() call
on Windows (Linux handles this implicitly but Windows requires writability
poll after non-blocking connect)
- Add net::isConnectionClosed() helper: treats WSAENOTCONN/WSAECONNRESET/
WSAESHUTDOWN/WSAECONNABORTED as graceful peer-close rather than recv errors
- Apply isConnectionClosed() in both WorldSocket and TCPSocket recv loops
UI:
- Add renderBossFrames(): displays boss unit health bars in top-right corner
when SMSG_UPDATE_INSTANCE_ENCOUNTER_UNIT has active slots; supports
click-to-target and color-coded health bars (red→orange→yellow as HP drops)
- SMSG_RESUME_CAST_BAR: parse packed_guid caster/target + spellId + remainingMs +
totalMs; restores cast bar state when server re-syncs a cast in progress
- SMSG_THREAT_UPDATE: properly consume packed_guid host/target + threat entries
to suppress unhandled packet warnings
- SMSG_UPDATE_INSTANCE_ENCOUNTER_UNIT: track up to 5 boss encounter unit guids
per slot; expose via getEncounterUnitGuid(slot); clear on world transfer
These guids identify active boss units for raid/boss frame display.
These two opcodes were accidentally falling through to the PERIODICAURALOG
handler which expects packed_guid+packed_guid+uint32+uint32 — wrong format.
Now:
- SMSG_SPELL_DELAYED: parse caster guid + delayMs, extend castTimeRemaining
on player cast pushback (spell cast bar stays accurate under pushback)
- SMSG_EQUIPMENT_SET_SAVED: simple acknowledge log (no payload needed)
- SMSG_MULTIPLE_MOVES uses the same uint8-size+uint16-opcode format as
SMSG_COMPRESSED_MOVES; route it to handleCompressedMoves() so bundled
monster movement updates are processed instead of dropped
- SMSG_PROCRESIST: parse caster/victim GUIDs and show MISS combat text
when the player's proc was resisted by an enemy spell
- Play SpellSoundManager::playImpact() with correct school when the player
is hit by another unit's spell (SMSG_SPELL_GO hitTargets check)
- Show achievement name in SMSG_SERVER_FIRST_ACHIEVEMENT notifications
using the already-loaded achievementNameCache_
- playImpact was fully implemented but never called; now wired up
