Mount Animation System:
- Property-based jump animation discovery using sequence metadata
- Chain linkage scoring (nextAnimation/aliasNext) for accurate detection
- Correct loop detection: flags & 0x01 == 0 means looping
- Avoids brake/stop animations via blendTime penalties
- Works on any mount model without hardcoded animation IDs
Mount Physics:
- Physics-based jump height: vz = sqrt(2 * g * h)
- Configurable MOUNT_JUMP_HEIGHT constant (1.0m default)
- Procedural lean into turns for ground mounts
- Smooth roll based on turn rate (±14° max, 6x/sec blend)
Audio Improvements:
- State-machine driven mount sounds (jump, land, rear-up)
- Semantic sound methods (no animation ID dependencies)
- Debug logging for missing sound files
Bug Fixes:
- Fixed mount animation sequencing (JumpStart → JumpLoop → JumpEnd)
- Fixed animation loop flag interpretation (0x20 vs 0x21)
- Rider bone attachment working correctly during all mount actions
Network Protocol:
- Add SMSG_TALENTS_INFO (0x4C0) packet parsing for talent data
- Add CMSG_LEARN_TALENT (0x251) to request learning talents
- Add MSG_TALENT_WIPE_CONFIRM (0x2AB) opcode for spec switching
- Parse talent spec, unspent points, and learned talent ranks
DBC Parsing:
- Load Talent.dbc: talent grid positions, ranks, prerequisites, spell IDs
- Load TalentTab.dbc: talent tree definitions with correct field indices
- Fix localized string field handling (17 fields per string)
- Load Spell.dbc and SpellIcon.dbc for talent icons and tooltips
- Class mask filtering using bitwise operations (1 << (class - 1))
UI Implementation:
- Complete talent tree UI with tabbed interface for specs
- Display talent icons from spell data with proper tinting/borders
- Enhanced tooltips: spell name, rank, current/next descriptions, prereqs
- Visual states: green (maxed), yellow (partial), white (available), gray (locked)
- Tier unlock system (5 points per tier requirement)
- Rank overlay on icons with shadow text
- Click to learn talents with validation
Dual Spec Support:
- Store unspent points and learned talents per spec (0 and 1)
- Track active spec and display its talents
- Spec switching UI with buttons for Spec 1/Spec 2
- Handle both SMSG_TALENTS_INFO packets from server at login
- Display unspent points for both specs in header
- Independent talent trees for each specialization
The quest log was empty because the client never requested quest data from the server.
This caused "Already on that quest" errors when trying to turn in completed quests.
Solution:
- When gossip opens with an NPC, parse quest icons to determine quest status
- Quest icon decoding: 0x04=completable (turn-in), 0x02=available, 0x01=incomplete
- Populate questLog_ with active quests and their completion status
- selectGossipQuest now checks questLog_ and sends correct packet:
* If quest is in log + complete → CMSG_QUESTGIVER_REQUEST_REWARD (turn-in)
* Otherwise → CMSG_QUESTGIVER_QUERY_QUEST (view details)
Added opcodes:
- CMSG_QUEST_QUERY (0x05C) - client requests quest template data
- SMSG_QUEST_QUERY_RESPONSE (0x05D) - server sends quest template
Debug logging:
- Logs when quests are added/updated in quest log
- Logs selectGossipQuest decisions (isInLog, isCompletable)
- Logs whether turning in or querying quest
Also lowered quest marker height by 1 unit (HEIGHT_OFFSET 2.1 → 1.1).
Quest turn-in now works correctly!
Corrected opcode assignments:
- 0x18F = SMSG_QUESTGIVER_QUEST_INVALID (not QUEST_COMPLETE)
- 0x191 = SMSG_QUESTGIVER_QUEST_COMPLETE
SMSG_QUESTGIVER_QUEST_INVALID payload is uint32 QuestFailedReason:
- 0 = Don't have quest
- 1 = Quest level too low
- 4 = Insufficient money
- 5 = Inventory full
- 13 = Already on that quest
- 18 = Already completed quest
- 19 = Can't take any more quests
The "quest ID 13" we were seeing was actually failure reason 13
("Already on that quest"), not a quest ID at all.
Corrected opcode from 0x191 to 0x18F for WoW 3.3.5a. This fixes
auto-completing quests like "A Threat Within" that complete upon
speaking with the NPC.
Fix SMSG_BINDPOINTUPDATE opcode from 0x1B3 to 0x155 — the old value
collided with SMSG_TRAINER_BUY_SUCCEEDED, causing buy responses to be
misinterpreted as bindpoint updates. Add specialization tabs using
SkillLineAbility.dbc to group spells by class spec (category 7).
Add 36 arena and battleground opcodes with handlers for queue status, team events, invites, and errors. Fix SMSG_FORCE_RUN_SPEED_CHANGE parsing (uint8 not uint32) and remove manual mount speed tracking. Buff bar now shows spell icons and is positioned below the minimap. Both mouse buttons cancel autorun.
- Fix SMSG_FORCE_RUN_SPEED_CHANGE parsing (missing uint32 field caused garbage speed)
- Always send speed ACK to prevent server stall, even on invalid values
- Defer mount model loading to next frame to avoid render-loop hang
- Compute mount height from tight vertex bounds instead of M2 header bounds
- Dismount when entering combat or casting spells while mounted
- Prevent auto-attacking yourself when self-targeted
- Leave combat when 40+ yards from target, close vendor at 15+ yards
- Pre-open X11 display for reliable mouse release in signal handlers
Render mount M2 model under player with seated animation, apply creature
skin textures, server-driven speed via SMSG_FORCE_RUN_SPEED_CHANGE, and
/dismount command. X11 XUngrabPointer on crash/hang to always release mouse.
