Closed: jump server packet (002), facing direction (003), run speed (004). New: collision penetration (005), corner stuck (006), missing trees (007). All collision bugs stem from static-overlap detection instead of swept-sphere — needs Transition restructure to use FindTimeOfCollision.

Track visual, gameplay, and protocol bugs here. Close by moving to

|
|
### BUG-001: Wrong cloth textures on characters
|
|
- **Observed:** 2026-04-13
|
|
- **Description:** Character clothing renders with incorrect textures.
|
|
ObjDesc Phase 5 (AnimPartChange + TextureChanges + SubPalettes) is
|
|
shipped but something is off — either a texture-swap ordering issue,
|
|
a missing remapping step, or a palette application bug.
|
|
- **Repro:** Connect to ACE server, observe player character or NPCs.
|
|
- **Likely area:** `WorldEntity` ObjDesc application, `TextureCache`,
|
|
or the CreaturePalette pipeline in `InstancedMeshRenderer`.
|
|
- **Phase:** Unassigned (investigate after rendering rebuild Step 5).
|
|
|
|
### BUG-005: Collision penetration — body enters objects before blocking
|
|
- **Observed:** 2026-04-14
|
|
- **Description:** Player walks partway into boulders, trees, and walls
|
|
before collision is detected. Root cause: static overlap detection
|
|
instead of swept-sphere. Retail uses FindTimeOfCollision to compute
|
|
the exact contact point BEFORE moving the sphere. Our system moves
|
|
first, detects overlap, then tries to push out.
|
|
- **Repro:** Walk into a boulder at any speed — body clips into it.
|
|
- **Fix required:** Restructure Transition loop to compute collision
|
|
time before advancing position. Use CollisionPrimitives.FindTimeOfCollision
|
|
(already ported from FUN_00539BA0).
|
|
- **Phase:** B.3 (collision completion)
|
|
|
|
### BUG-006: Getting stuck at object corners and tight spaces
|
|
- **Observed:** 2026-04-14
|
|
- **Description:** Player gets permanently stuck when walking into
|
|
building corners or between objects. The SlideSphere crease projection
|
|
degenerates when two collision normals are nearly parallel or the
|
|
sphere is already penetrating.
|
|
- **Repro:** Run along a building wall and hit a corner.
|
|
- **Fix required:** Pre-move collision prevents penetration (fixes
|
|
BUG-005), which eliminates the degenerate crease case. Also need
|
|
stuck detection + push-out as a safety valve.
|
|
- **Phase:** B.3 (collision completion)
|
|
|
|
### BUG-007: Some trees don't have collision
|
|
- **Observed:** 2026-04-14
|
|
- **Description:** Some scenery trees/objects pass through despite
|
|
CylSphere collision being implemented. Likely missing CylSphere
|
|
data in their Setup, or the Setup isn't cached in PhysicsDataCache.
|
|
- **Repro:** Walk through certain trees near Holtburg.
|
|
- **Phase:** B.3 (collision completion)
|

## Fixed
|
|
|
|
### BUG-002: Jump not visible from retail client
|
|
- **Fixed:** 5634e71 — Jump packet (opcode 0xF61B) now sent to server.
|
|
|
|
### BUG-003: Facing direction mismatch with server
|
|
- **Fixed:** 6523c71 — YawToAcQuaternion converts from our yaw convention
|
|
to AC heading (0=West, 90=North) using holtburger's from_heading formula.
|
|
|
|
### BUG-004: Run speed not verified working
|
|
- **Fixed:** bb7eced — Server doesn't echo UpdateMotion to sender. Compute
|
|
RunRate locally via PlayerWeenie.InqRunRate (Run skill 200 → 9.5 m/s).
