Game name uses big-endian (not reversed), platform/os/locale use
little-endian with chars reversed and null at end (not beginning).
Protocol version is 8 for WoW 3.3.5a, not 3.
Account for PIN/matrix/authenticator extra data in packet size
calculation to prevent receive buffer corruption. Add hex dump
of raw auth packets and show actual server error codes.
TrinityCore/AzerothCore's UpdateBigNumbers uses BN_num_bytes (natural
size without padding) when hashing values for u and M1. Our code was
using fixed 32-byte padding which produces different hashes when any
value (salt, A, B, N) has leading zeros in big-endian representation.
Two bugs that caused the server to always reject our login proof:
- N was hashed as 256 bytes (2048 bits) instead of 32 bytes (256 bits),
producing completely wrong H(N)^H(g) and therefore wrong M1
- Session key computation B-k*g^x could go negative; OpenSSL's
BN_mod_exp doesn't handle negative bases. Add k*N before subtracting
(standard TrinityCore approach) to keep the value positive
Three critical bugs fixed:
- LOGON_CHALLENGE request: set protocol byte to 0x03 (was 0x00) and
reverse FourCC strings (game/platform/os/locale) to match real client
- Response parsers: remove double-read of opcode byte that shifted all
field reads by one, preventing successful auth with real servers
- LOGON_PROOF response sizes: success=32 bytes, failure=4 bytes to match
TrinityCore/AzerothCore format
Also adds missing auth result codes (0x13-0x20, 0xFF) including
IGR_WITHOUT_BNET (0x17) which Warmane was returning.
Replace the 3D top-down rendered minimap with WoW's native pre-rendered
BLP tile textures loaded via md5translate.trs. Tiles are composited into
a 3x3 grid FBO with proper axis transposition matching the ADT terrain
convention. The screen shader provides camera-rotation, circular mask,
directional player arrow, and 20% transparency. Minimap is now on by
default with the N toggle key removed.
Teleporter panel (T key) lets the player teleport between Goldshire,
Stormwind Gate, Ironforge, and Westfall in single-player mode. Adds
serverToCanonical/canonicalToServer conversion at the network packet
boundary so positions are compatible with TrinityCore/MaNGOS/AzerothCore
emulator servers.
Centralizes all coordinate conversions in core/coordinates.hpp with
proper canonical WoW coords (+X=North, +Y=West, +Z=Up). Fixes critical
tile calculation bug that was loading wrong surrounding tiles during
terrain streaming, and fixes position sync sending ADT-raw format
instead of canonical coordinates to the server.
Drop specular lighting from terrain shader — ground materials (dirt, grass,
stone) are purely diffuse and specular highlights made them look plastic.
Replace Reinhard tonemapper with a shoulder-only compressor that is identity
below 0.9 and softly rolls off HDR values above, preserving scene contrast.
Replace hardcoded specular multipliers with uLightColor * uSpecularIntensity
uniforms in all 4 world shaders (terrain, WMO, M2, character), set HDR sun
color (1.5, 1.4, 1.3) and specular intensity 0.5 so highlights can exceed
1.0, and switch the post-process pass from passthrough to exposure-compensated
Reinhard (exposure=1.8) for soft highlight roll-off without clipping.
Render the world into an off-screen MSAA RGBA16F framebuffer, resolve
to a regular texture, then blit to screen via a fullscreen quad shader.
This sets up the infrastructure for future HDR tonemapping and SSAO
(depth texture preserved for sampling). Currently a passthrough until
HDR light sources are added. Login screen bypasses the FBO and renders
directly to the default framebuffer.
Anisotropic filtering now queries GL_MAX_TEXTURE_MAX_ANISOTROPY_EXT once
and applies via a single applyAnisotropicFiltering() utility, replacing
hardcoded calls across all renderers. Fog (sky horizon color, 100-600
range) and Blinn-Phong specular highlights are added to WMO, M2, and
character shaders for visual parity with terrain. Shadow sampling
plumbing (sampler2DShadow with 3x3 PCF) is wired into all three shaders
gated by uShadowEnabled, ready for a future shadow map pass.
Replace UV scroll workaround for chimney smoke with proper GL_POINTS
particle system. Smoke particles rise, expand, drift, and fade over
4-7 seconds. One in eight particles spawns as a bright orange/red
ember spark. Enable 4x multisample antialiasing for smoother edges
on player models, fences, and foliage.
- Parse global sequence durations from M2 binary and use them in bone
interpolation so torches, candles, and other env doodads animate.
- Add UV scroll shader effect for smoke models (HouseSmoke, SmokeStack)
as a workaround for unimplemented M2 particle emitters.
- Tighten WMO floor probe heights to prevent multi-story buildings from
returning the wrong floor, fixing player clipping through inn floors
and camera locking onto the second floor.
- Use player ground level as reference for camera orbit floor collision
so the camera doesn't fight upper floors in buildings.
- Loading screen stays visible until all terrain tiles finish streaming;
character spawns only after terrain is loaded and Z-snapped to ground
- Reduce tree trunk collision bounds (5% of canopy, capped at 5.0) and
make all small/medium trees, bushes, lily pads, and foliage walkthrough
- Add jump input buffering (150ms) and coyote time (100ms) for responsive jumps
- Fix fence orientation by adding +180° heading rotation
- Increase terrain load radius from 1 to 2 (5x5 tile grid)
- Add hearthstone callback for single-player camera reset
- Add idle variation system: creatures randomly play Stand variations
(stretch, flap, look around) every 4-10s, then return to idle loop
- Deduplicate M2 instances at same position (was hidden before animation
made duplicates visible with different random start times)
- Adaptive M2 render distance: 350 units in open terrain, 180 in cities
- Restore terrain sampler-to-unit uniform bindings lost during texture
bind optimization (roads were invisible under grass)
- Safety: clamp bone count to 128, validate sequence indices, sanitize scale
- Implement GPU bone skinning for M2 doodads/creatures (gryphons, birds)
- Store bone hierarchy and animation keyframes per model
- Compute bone matrices per-instance with keyframe interpolation
- Upload bone weights/indices in vertex buffer, skinning in vertex shader
- Fix terrain texture rendering: restore sampler-to-unit uniform bindings
removed during texture bind optimization (roads were invisible)
- Add spellbook screen (P key) with Spell.dbc name lookup and action bar assignment
- Default Attack and Hearthstone spells available in single player
- Fix WMO floor clipping (gryphon roost) by tightening ceiling rejection threshold
- Darken ocean water, increase wave motion and opacity
- Add M2 model distance fade-in to prevent pop-in
- Reposition chat window, add slash/enter key focus
- Remove debug key commands (keep only F1 perf HUD, N minimap)
- Performance: return chat history by const ref, use deque for O(1) pop_front
Replace POSIX-specific socket and process APIs with portable
abstractions so the project builds on both Windows and Linux.
- Add include/network/net_platform.hpp: Winsock2/POSIX socket
abstraction (socket types, non-blocking, error handling,
WSAStartup lifecycle)
- Add include/platform/process.hpp: CreateProcess/fork+exec
abstraction for spawning ffplay subprocesses
- Update network module (tcp_socket, world_socket) to use
portable socket helpers instead of raw POSIX calls
- Update audio module (music_manager, footstep_manager,
activity_sound_manager) to use portable process helpers
instead of fork/exec/kill/waitpid
- Replace hardcoded /tmp/ paths with std::filesystem::temp_directory_path()
- Link ws2_32 and SDL2main on Windows in CMakeLists.txt
