Networked client on the existing Godot 4.7 + libgr2 renderer:
- net: m2dev wire protocol (libsodium KX + XChaCha20), auth/select/game
phases, EntityStore world model, ~all GC/CG headers. char create/delete,
private shop / mall / cube, SHOP_GC_START_EX, guild, party (+ CG_PARTY_SET_STATE),
quests, dragon soul, refine, safebox, exchange.
- UI: in-game windows migrated 1:1 from the reference uiscript/root .py —
char status (/stat), inventory+equipment, select-item ([SELECT_ITEM] quest
token), system-option + game-option + ESC system menu, private-shop 39-grid,
party info board, shop tabs, atlas, minimap, quickbar, chat, …
- EterGrnLib polish: GR2 material blend/two-sided, LOD crossfade, motion-event
dispatch, contact shadow, ray-AABB picking, weapon grip pre-transform.
Portable asset IO (A1) — all extension/libgr2/formats/mtproto reads routed
through godot::FileAccess (res:// PCK works on iOS/Android); standalone-lib
*_path() kept for the non-Godot CTests. AssetResolver + PropertyRegistry
switched to a baked index (bake_asset_index.gd) instead of std::filesystem.
Mobile builds: build-{android,ios}.sh, export-android.sh, pack-assets.sh,
gen-debug-keystore.sh. Assets ship as a zip mounted at runtime by
project/asset_pack.gd (adb push now; HTTP download is a drop-in later).
ctest 10/10, 34 GDScript suites, macOS/iOS/Android all build.

# oracle 运行手册(Oracle-Lite)
|
||
|
||
`oracle.c` 只用 `granny2` 的公开 C API(`granny.h`):文件 IO + 数学 + 写二进制,**不碰 GPU / D3D / EterGrnLib**。
|
||
所以除了原生 Windows,Wine 也能跑。
|
||
|
||
## 依赖
|
||
|
||
- `granny.h` + `granny2_x64.lib` + `granny2_x64.dll` —— 泄露 SDK 里就有:
|
||
`MobileSource/Cross Platform/Granny-3D-SDK-main/{include,lib/win64}/`
|
||
(32 位版在 `lib/win32/`。)
|
||
- 这套 DLL 是 **SDK 2.9.12**。资产由 **2.4.0.7** 导出(M0 T2 从解压后的 gr2 里读到)。
|
||
容器格式 + 组合公式(`BuildCompositeTransform4x4` / `ColumnMatrixMultiply4x3` / B 样条系数)
|
||
在 2.4–2.11 稳定,libgr2 的 self-check 6.1e-5 已印证。差异风险在 B 样条边界 / 少数曲线细节。
|
||
→ 先跑 `selfcheck`(下)确认坐标约定和 t=0 == bind pose,再决定是否换 2.4.x runtime(见 `GRANNY-VERSION.md`)。
|
||
|
||
## A. 原生 Windows(MSVC)
|
||
|
||
```bat
|
||
cmake -S oracle -B oracle\build -DGRANNY_SDK="C:\path\to\Granny-3D-SDK-main"
|
||
cmake --build oracle\build --config Release
|
||
oracle\build\Release\oracle.exe probe "assets\PC\ymir work\pc\warrior\warrior_cheongrin.gr2"
|
||
```
|
||
|
||
## B. macOS + Wine —— ✅ 已验证(macOS 26.4 / Apple Silicon)
|
||
|
||
```sh
|
||
brew install mingw-w64
|
||
# wine-stable cask 需要 sudo 装 gstreamer 依赖;无 sudo 时直接解包用:
|
||
tar -xf "$(ls ~/Library/Caches/Homebrew/downloads/*wine-stable*.tar.xz)" -C /tmp/wine
|
||
xattr -rc "/tmp/wine/Wine Stable.app"
|
||
WINE="/tmp/wine/Wine Stable.app/Contents/Resources/wine/bin/wine"
|
||
|
||
# 编译(脚本封装了 MinGW 的坑:granny.h 的 __int64 关键字)
|
||
oracle/build-wine.sh # → oracle/oracle.exe + oracle/granny2_x64.dll
|
||
|
||
# ⚠ WINEPREFIX 不能在 /tmp(Wine 拒绝在非属主目录建 prefix)
|
||
export WINEPREFIX="$HOME/.wine-oracle" WINEDEBUG=-all
|
||
"$WINE" wineboot --init # 首次,Rosetta 下 3–8 分钟
|
||
|
||
cd oracle
|
||
GR2='Z:\Users\me\...\assets\PC\ymir work\pc\warrior\warrior_cheongrin.gr2'
|
||
"$WINE" oracle.exe probe "$GR2"
|
||
"$WINE" oracle.exe dump "$GR2" - 0.0 \
|
||
-o 'Z:\Users\me\...\xrender-poc\test\oracle_dumps\cheongrin_bind_t0.bin' --mesh 4
|
||
"$WINE" oracle.exe dump "$GR2" 'Z:\...\action\dance_1.gr2' 11.333 \
|
||
-o 'Z:\...\test\oracle_dumps\cheongrin_dance1_t11.333.bin' --mesh 4
|
||
```
|
||
|
||
坑:① MinGW GCC 不认 `granny.h` 里的 `__int64` → `build-wine.sh` 用 `-D__int64="long long"`;
|
||
② Wine prefix 不能放 `/tmp`(非属主);③ wine-stable 首启会刷一大堆 MoltenVK 日志到 stderr,无害,`WINEDEBUG=-all` 挡不住它,grep 掉即可。
|
||
|
||
## C.(stretch)从 SDK source/ 移植 POSIX libgranny
|
||
|
||
`Granny-3D-SDK-main/source/` 有全套源码(62k 行)+ CMakeLists,但重度 Windows 化
|
||
(`winxx/win64/*.cpp`、`winxx_granny_windows.cpp`、`WINDOWS_IGNORE_PACKING_MISMATCH`)。
|
||
`wii/`、`wiiu/`、`ps3/` 目录里有 `ansi_*` 的通用实现可参考。真要做是几小时的平台层移植,
|
||
不在关键路径 —— 先走 A / B。
|
||
|
||
## 对拍(`tools/oracle_diff`)
|
||
|
||
```sh
|
||
build/tools/oracle_diff <model.gr2> <anim.gr2|-> <dump.bin> [--t <sec>] [--mesh N]
|
||
```
|
||
|
||
libgr2 侧用 `gr2::sample_pose` / `bind_pose` + 手写 LBS 算一遍,报:
|
||
- **gate 1**:骨骼世界矩阵 vs oracle 层① `max|Δ|`
|
||
- **gate 2**:mesh N 蒙皮顶点 vs oracle `max‖Δ‖`
|
||
- verdict:阈值 1e-3(noise_floor 就绪前)
|
||
|
||
**已跑结果**(Granny 2.9.12.0 vs libgr2):
|
||
|
||
| 用例 | mat max\|Δ\| | vtx max‖Δ‖ |
|
||
|---|---|---|
|
||
| `warrior_cheongrin` bind | 1.5e-5 | 4.6e-5 |
|
||
| `warrior_cheongrin` + `dance_1` @ t=0/4.7/11.333/20 | ≤ 4.1e-5 | ≤ 6.5e-5 |
|
||
| `assassin` bind(双 root + 非单位 InitialPlacement)| 3.1e-5 | 4.6e-5 |
|
||
|
||
全部 ≈ float32 累积误差 → **libgr2 的类型树 / 世界姿势 / OldCurve 求值 / CPU LBS 与真 Granny 数值一致**。
|
||
|
||
> 关键:`oracle.c` 的 `GrannyBuildWorldPose` 要把 model 的 `InitialPlacement` 当 `Offset4x4` 传
|
||
> (`GrannyGetModelInitialPlacement4x4`),否则非单位 InitialPlacement 的模型(如 assassin)会差一个平移。
|
||
> libgr2 的 `skeleton.initial_placement` 做同一件事。踩过一次。
|
||
|
||
## 产出
|
||
|
||
- dump → `test/oracle_dumps/`(布局见 `FORMAT.md`)
|
||
- 噪声地板 → `test/noise_floor.json`(`oracle dump` 跑同 `(model,anim,t)` 100 次 + 换一版
|
||
相邻 DLL 一次,取矩阵 / 顶点的 `max|Δ|`;M2 的 ε = 这个 ×10)
