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.

# MapCoord —— 网络实体坐标 ↔ Metin2World 本地坐标。
|
||
#
|
||
# M2Client 给的实体 pos 是「全局服务器 cm」经 position_to_godot 后的结果：
|
||
# net = (sx*0.01, h, -sy*0.01) （sx/sy 含地图 BasePosition）
|
||
# 而 Metin2World 的地形/物件是「地图本地」帧（tile 0 在原点，+Z 朝南）：
|
||
# world = ((sx-bx)*0.01, h, (sy-by)*0.01)
|
||
# 两者差一个 BasePosition 平移 + Z 轴翻向。没对齐时角色会飘在几公里外的黑void里。
