- Skip wall collision sweep entirely when player isn't moving (saves all
collision calls when standing still)
- Reduce max sweep steps from 4 to 2 with 1.0f step size (all paths:
follow, free-fly, swimming)
- Cache floor height between frames, reuse when position changes <0.5 units
- Fix floor height not updating after walking off tall objects (fountain etc)
by always smoothing toward detected ground instead of ignoring drops >2 units
- Reduce free-fly ground probes from 5 to 1
- Disable WMO camera collision (raycast + floor probes) for performance
- Add spatial grid to raycastBoundingBoxes for when camera collision is re-enabled
Build a 2D triangle grid per WMO group at load time so getFloorHeight and
checkWallCollision only test triangles in nearby cells instead of brute-forcing
all triangles. Also reduce sweep steps (12→4), ground probes (3→1), camera
floor probes (5→2), throttle isInsideWMO to every 10 frames, and early-out
wall collision on first hit.
- Fix CMSG_BUY_ITEM count field from uint8 to uint32 (server silently dropped undersized packets)
- Character select screen: remember last selected character, two-column layout with details panel, double-click to enter world, responsive window sizing
- Fix stale character data between logins by replacing static init flag with per-character GUID tracking
- Parallelize WMO visibility culling across worker threads (same pattern as M2 renderer)
- Optimize WMO collision queries with world-space group bounds early rejection in getFloorHeight, checkWallCollision, isInsideWMO, and raycastBoundingBoxes
- Reduce camera ground samples from 5 to 3 movement-aligned probes
- Add WMO interior lighting, unlit materials, vertex color multiply, and alpha blending support
Split the M2 animation update loop into three phases: sequential animation state update, parallel bone matrix computation via std::async (when 32+ animated instances), and sequential particle update. Each thread processes a disjoint slice of instances so no synchronization is needed.
Enrich online inventory from local DB when server data is incomplete, add
resolveOnlineItemGuid fallback for sell/equip/use, use async enqueueTile for
initial terrain load, improve walk/run animation fallbacks, clear target on
loot close, and broaden equipability detection to include armor/subclass.
Reset NPC animation to idle when health goes from 0 to >0 (respawn), prevent
dead NPCs from being moved by server movement packets. Fix faction hostility
to check factionGroup Monster bit and individual enemy arrays, not just
enemyGroup. Add level-based mob coloring: grey (no XP), green (easy), yellow
(even), orange (hard), red (very hard) for target frame and selection circle.
Fix spell cast target fallback using selected target instead of no-op tautology.
Fix SMSG_ITEM_QUERY_SINGLE_RESPONSE to always read 10 stat pairs (server sends
all 10 regardless of statsCount), fixing misaligned armor/stat reads. Fix XP gain
parser to read float groupRate + uint8 RAF instead of bogus uint32 groupBonus.
Add item icons and quality-colored names to loot window. Use actual character
appearance bytes for CharSections.dbc skin/face/hair lookups instead of hardcoded
defaults. Add weapon-type-aware attack animation selection (2H prioritizes anim 18).
Add readable spell cast failure messages and vendor sell hint.
Use getRemainingTileCount (pending + readyQueue) and processAllReadyTiles
to prevent loading screen from exiting before tiles are finalized. Auto-select
realm and character when only one is available.
Enhanced the C-key character screen with a 3-column layout featuring a 3D
character model preview (with drag-to-rotate), item icons loaded from BLP
textures via ItemDisplayInfo.dbc, and a stats panel showing base + equipment
bonuses. Fixed selection circle clipping under terrain by adding a Z offset,
and corrected faction hostility logic that was wrongly marking hostile mobs
as friendly.
Split inventory into bags-only (B key) and character screen (C key). Vendor window
auto-opens bags with sell prices on hover and right-click to sell. Add camera intro
pan on all login/spawn/teleport/hearthstone events and idle orbit after 2 minutes.
Add quest log UI, SMSG_MONSTER_MOVE handling, deferred creature spawn queue, and
creature fade-in/movement interpolation for online mode.
Replace flat mesh rendering of additive/mod blend batches (blendMode >= 3)
with camera-facing point sprites using a soft radial gradient texture and
additive blending. Adds M2 particle emitter infrastructure (structs, shader,
parsing stubs) but disables emitter parsing — the assumed 476-byte struct
size is wrong for WotLK 3.3.5a, causing misaligned reads that explode RAM.
Batches with the M2 unlit material flag (0x01) or additive blend modes
(3+) now skip lighting, shadows, and fog, emitting texture color directly.
Fixes lantern glow quads appearing as dull transparent circles.
Water/lava batches in fountain and Ironforge M2 models use non-opaque
blend modes (alpha, additive) defined in the M2 material table. Without
parsing these, they rendered as solid surfaces extending visibly beyond
their containers. Now each batch looks up its blend mode from the
material array and sets the appropriate GL blend function.
Parse M2TextureTransform entries and texture transform lookups from the
M2 binary, then apply per-batch UV offsets in the vertex shader using
the existing animation time base and global sequence durations.
Use CharHairGeosets.dbc to map (race, sex, hairStyleId) to the correct
group 0 scalp mesh instead of the broken 101+hairStyleId formula. Filter
group 0 submeshes so only the body base and correct hair mesh render
(prevents overlapping scalp variants). Fix ItemDisplayInfo.dbc column
indices (5→7) and geoset formulas for equipment. Add CharSections.dbc
hair texture lookup and CharacterFacialHairStyles.dbc support.
- Remove complex ramp/edge filtering that was skipping building walls
- Simpler wall detection: any vertical geometry above step height
- Add intro camera pan on game start
Save/load floor cache per map (e.g., cache/wmo_floor_Azeroth.bin) instead
of a single global file. Saves current zone's cache before teleporting,
loads target zone's cache after terrain streaming completes.
Add precomputeFloorCache() method that samples all WMO bounds at load time
and populates the persistent floor height grid. Called after terrain
streaming completes (initial spawn and teleport) when cache is empty.
- Add texture-sorted batch merging with glMultiDrawElements to reduce draw calls
- Pre-compute merged batches at load time instead of per-frame
- Add persistent floor height cache with disk save/load (cache/wmo_floor_cache.bin)
- Reduce collision focus radius and sweep steps for faster collision checks
- Add floor cache size to performance HUD
- Reduce WMO group distance culling to 80 units
Renders bounding boxes in depth-only pre-pass and queries GPU for
visibility. Groups fully occluded in previous frame are skipped.
Significantly improves performance in dense areas like Stormwind.
Portal-based visibility culling for WMO rendering (disabled by default,
needs debugging for complex WMOs like Stormwind). Skip character creation
screen when characters already exist in single-player mode.
Render an animated M2 character model in the creation screen using a
dedicated CharacterRenderer with an offscreen FBO. Preview updates on
race/gender/appearance changes, supports mouse-drag rotation, and
composites skin, face, hair scalp, and underwear textures from
CharSections.dbc. Extracts getPlayerModelPath() to a shared free
function in game/character.
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.
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.
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
