The Nullified Statue of a Drudge renders correctly in color/shape
after Phase 5b's SubPalette fix, but the user reported it's rendering
at base drudge size when it should be larger. AC statues use the
PhysicsDescriptionFlag.ObjScale field to scale the base mesh; my
parser was consuming-and-skipping those 4 bytes.
Changes:
- CreateObject.TryParse: extract the u32 float from the ObjScale
field instead of advancing past it. Declaration moved to the top
of the method alongside other accumulators so the PartialResult
local function at the bottom can reference it for the truncation
fallback path. Same structural change for position and setupTableId
since PartialResult already needed them too.
- CreateObject.Parsed gains ObjScale (float?).
- WorldSession.EntitySpawn gains ObjScale; propagated through the
fire site in ProcessDatagram.
- GameWindow.OnLiveEntitySpawned bakes a scale matrix into every
MeshRef's PartTransform when ObjScale != 1.0, following the same
pattern the offline scenery hydration already uses. No change to
WorldEntity or StaticMeshRenderer — the scale is absorbed into the
per-part transform the renderer already multiplies through.
Tests: 77 core + 83 net = 160, all green.

Finishes the TextureChange half of ObjDesc. Characters' clothing now
renders with correct per-part textures (user-verified "looks good"
after previous "partial coverage" / "wrong clothes"). The Nullified
Statue still looks like a flesh-colored drudge because the statue's
color comes from SubPalettes (palette-indexed texture recoloring),
which is the remaining major Phase 5 piece.
The first attempt at TextureChange application was silently broken by
an ID-type mismatch: the server encodes OldTexture/NewTexture as
SurfaceTexture (0x05XXXXXX) ids, but my sub-meshes are keyed by
Surface (0x08XXXXXX) ids. The override dict was keyed by one type
and looked up by the other, so TryGetValue never hit and no override
actually applied.
Diagnosed via Phase 1 systematic debugging with resolve-level logging:
live: spawn +Acdream texChanges=20
live: texChange part=0 old=0x05000BB0 new=0x0500025D
...
live: resolve part=0 surface=0x08000519 origTex=0x05000BB0 [MATCH]
live: resolve part=0 surface=0x0800051C origTex=0x05000CBE [MATCH]
... 10/10 lines [MATCH]
The [MATCH] lines proved the server's OldTexture IS reachable via a
Surface→OrigTextureId lookup, just needed keying by the right value.
Fix:
- TextureCache.GetOrUploadWithOrigTextureOverride(surfaceId, origTexOverride):
loads the base Surface dat for its color/flags/palette, but
substitutes the override SurfaceTexture id in the decode chain.
Caches under a (surfaceId, origTexOverride) composite key.
- MeshRef.SurfaceOverrides is now Dictionary<uint, uint> keyed by
Surface id, value = replacement OrigTextureId. Null means no
overrides.
- GameWindow.OnLiveEntitySpawned now does TWO passes when texture
changes are present:
1. Group the raw server changes by PartIndex into (oldOrigTex →
newOrigTex) dicts
2. For each affected part's post-animPartChange GfxObj, iterate
its Surfaces list, resolve each Surface → OrigTextureId, and
if that matches a raw change's oldOrigTex, write an entry
Surface id → newOrigTex into the final override map
- StaticMeshRenderer.Draw: when sub-mesh surface id has an override,
call GetOrUploadWithOrigTextureOverride instead of GetOrUpload.
Verified live: +Acdream's clothing renders correctly, NPCs are
"much better" (characters previously naked are now dressed). Statue
has the full mechanical pipeline working (resolve diagnostic shows
2/2 Surfaces [MATCH] for the statue's override dict) but its visible
color comes from the separate SubPalette overlay that isn't wired yet.
Also added a statue-targeted diagnostic block that dumps its full
ObjDesc contents (texChanges + subPalettes + animPartChanges) by
name match, which is how I traced the Nullified Statue of a Drudge's
specific ObjDesc. Lives under `if (isStatue && ...)` so normal logins
aren't spammed.
Cross-referenced against two new references this session:
* references/Chorizite.ACProtocol (cloned from github.com/Chorizite/
Chorizite.ACProtocol.git on user's suggestion) — confirms the
ObjDesc field order and PackedDword-of-known-type convention.
* references/WorldBuilder/... (already in repo) — confirms the
Surface→OrigTexture→SurfaceTexture→RenderSurface chain and the
P8/INDEX16 palette decode path.

statue identified (Phase 4.7h/i/j/k/l)
Makes three big improvements to the CreateObject decode path:
1. Extract AnimPartChanges from the ModelData section instead of
skipping them. Each change is (PartIndex, NewModelId); the server
uses these to replace base Setup parts with armor/clothing/statue
meshes. The player character has ~34 of them on a normal login.
2. Flow AnimPartChanges through WorldSession.EntitySpawn into
GameWindow.OnLiveEntitySpawned, which now patches the flattened
Setup's part list BEFORE uploading GfxObjs. Patching is a simple
"parts[change.PartIndex] = new MeshRef(change.NewModelId, oldTransform)"
keeping the base Setup's placement transform but swapping the mesh.
3. Read the WeenieHeader Name (String16L) that follows the PhysicsData
section. Required walking past every remaining physics flag (Parent,
Children, ObjScale, Friction, Elasticity, Translucency, Velocity,
Acceleration, Omega, DefaultScript, DefaultScriptIntensity) plus the
9 sequence timestamps (2 bytes each) plus 4-byte alignment. The
Name field is then the second thing in the WeenieHeader after
u32 weenieFlags.
Critical bug fix in the same commit: ACE's WritePackedDwordOfKnownType
STRIPS the known-type high-byte prefix (e.g. 0x01000000 for GfxObj ids)
before writing the PackedDword. The first version of AnimPartChange
decoding called plain ReadPackedDword, so it got 0x0000XXXX instead of
0x0100XXXX and every GfxObj dat lookup silently failed — the drop
counter showed 19+ noMeshRef drops including +Acdream himself.
Added ReadPackedDwordOfKnownType that ORs the knownType bit back in
on read (with zero preserved as the "no value" sentinel). After the
fix, noMeshRef drops = 0 across a full login.

The statue's exact data is now known and the hydration path runs
without errors. The user's "look at the Name field in the CreateObject
body" insight turned this from an unbounded visual hunt into a targeted
grep of ~60 log lines.
Tests: 77 core + 83 net = 160 passing (offline suite unchanged).
Live handshake + enter-world tests still pass.

The end-to-end pipeline. acdream can now connect to a live ACE server,
complete the full handshake + character-select + enter-world flow, and
stream CreateObject messages straight into the existing IGameState and
static mesh renderer. Gated behind ACDREAM_LIVE=1 so the default
offline run path is untouched.
Added:
- AcDream.Core.Net.WorldSession: high-level session type that owns a
NetClient, drives the 3-leg handshake, parses CharacterList, sends
CharacterEnterWorldRequest + CharacterEnterWorld, and converts the
post-login fragment stream into C# events. State machine:
Disconnected → Handshaking → InCharacterSelect → EnteringWorld →
InWorld (or Failed). Public API:
* Connect(user, pass) — blocks until CharacterList received
* EnterWorld(user, characterIndex) — blocks until ServerReady
* Tick() — non-blocking, call per game-loop frame
* event EntitySpawned
* event StateChanged
* Characters property (populated after Connect)
- NetClient.TryReceive: non-blocking variant that returns immediately
with null if the kernel buffer is empty. Enables draining packets
per frame from the main thread without stalling.
- GameWindow live-mode hookup:
* AcDream.Core.Net project reference
* TryStartLiveSession() called after dat hydration, gated behind
ACDREAM_LIVE=1 + ACDREAM_TEST_USER/ACDREAM_TEST_PASS env vars
* Subscribes EntitySpawned to OnLiveEntitySpawned
* Calls Connect() then EnterWorld(0) synchronously on startup
* OnLiveEntitySpawned hydrates mesh refs from the Setup dat
(same SetupMesh.Flatten + GfxObjMesh.Build + StaticMesh.EnsureUploaded
path used by scenery), publishes a WorldEntitySnapshot via
_worldGameState.Add + _worldEvents.FireEntitySpawned, and
appends to _entities so the next frame picks it up
* OnUpdate calls _liveSession?.Tick() each frame
* OnClosing disposes the session
* Position translation: server sends (LandblockId, local XYZ +
quaternion); we map landblock to world origin relative to the
rendered 3x3 center, add local XYZ, translate AC's (W,X,Y,Z)
quaternion wire order to System.Numerics.Quaternion (X,Y,Z,W)

live: (suppressing further spawn logs)
First line: +Acdream himself. setup=0x02000001 is ACE's default humanoid
player mesh. world coords match Holtburg (landblock 0xA9B4 local
space). Subsequent spawns are weenies at various setup ids — likely
the foundry statue, street lamps, drums, etc. The 0x7A9B4xxx GUID
pattern is ACE's convention: scenery-type (0x7) + landblock (0xA9B4) +
per-object index.
All spawns flow through the SAME SetupMesh/GfxObjMesh/StaticMeshRenderer
pipeline used by scenery and interiors today. The plugin system's
EntitySpawned event fires on every new entity, so plugins can see
them without any networking awareness.
Tests: 160 passing offline (77 core + 83 net). The live handshake and
enter-world tests are gated and still pass when ACDREAM_LIVE=1.
User visual verification is the final acceptance for Phase 4. Run
with ACDREAM_DAT_DIR + ACDREAM_LIVE=1 + ACDREAM_TEST_USER=testaccount
+ ACDREAM_TEST_PASS=testpassword and look for +Acdream's model + the
foundry statue standing on top of the Holtburg foundry.
