IW4L + Apex (分支)
這是 vladtrc/iw4L（分支
apex-movement）的分支，將 MW2 的移動與槍械替換為來自
ApexRuntime 的 Apex 英雄移動與武器行為：以離線 R5Flowstate 為基準進行量測，並從零重新實作。選用的 Apex 模型、音效與 HUD 來自你個人的匯出檔；本儲存庫中不包含任何此類內容。
安裝： 將此儲存庫複製到 ApexRuntime 旁邊，並依照
ApexRuntime 的 INSTALL.md 操作。
建置完成後的快速開始：. un-apex.ps1。
與上游的差異大多位於 crates/sim/src/apex*.rs、
crates/render_anim/src/anim/apex_*.rs、crates/render_gpu/src/drawsurf/apex_*、
crates/audio/src/apex_weapon_sfx.rs、crates/console/src/apex_*.rs、
crates/asset_game/src/apex_weapons.rs 與 run-apex.ps1。與上游 IW4L 作者、Activision、EA 或 Respawn 均無關聯。
以下為原始 IW4L README。
IW4L
IW4L 是《決勝時刻：現代戰爭 2》（2009）的開源執行階段，以
Rust 搭配 Bevy 撰寫。將它指向你已擁有的 MW2 副本，它
就會將該安裝的地圖、模型、材質與武器載入自己的引擎。你可以
在多人遊戲地圖上試玩已實作的移動與戰鬥，然後檢視或變更這些
系統的運作方式。
README 圖片：IW4L 中的炸彈安裝
README 圖片：IW4L 中的油罐車爆炸
你可以試玩的內容
探索地圖、與機器人對戰，以及錄製與重播 demo。遊戲玩法仍不完整；
預期會有缺失的行為、錯誤與不同步。資源讀取器也涵蓋 MW3 與 Black
Ops。
從原始碼建置。API、設定、快取與網路協定會在不同
提交之間變動；多人遊戲的對等端必須執行相同的提交。
建置與執行
透過 rustup 與 GNU Make 安裝 Rust。建置相依項目 涵蓋
Linux 的 C/C++ 工具鏈與系統函式庫，以及 macOS 的 Xcode 命令列工具。
Windows 指示 涵蓋建置與整理可攜式資料夾。
你需要自己安裝的 MW2 多人遊戲資料，包括 common_mp.ff。IW4L
不散布任何遊戲資源，並且讀取安裝時不會修補或取代其
檔案。快取、demo 與日誌會放在 iw4l-artifacts/ 之下；Linux 設定使用另外的
設定目錄，詳見執行指南。
從儲存庫根目錄：
cp .env.example .env
# Edit .env: set IW4L_GAMES to the folder containing your game installations.
make map mp_boneyard CMDS='wait world; spawn 0; force_match_start; bot add 3'
這會建置最佳化的 play 設定檔，並以三個機器人啟動本機對戰。
force_match_start 會跳過否則會凍結移動的暖機。
引擎內部
| 領域 | 實作 |
|---|---|
| 資源 | 原生 FastFile 讀取器會將遊戲資料轉換為共用的中介表示。 |
| 著色器 | 零售版 Direct3D 9 Shader Model 3 位元碼會轉譯為 WGSL。 |
| 渲染 | 世界幾何、模型與特效會饋入單一排序的繪製表面清單。 |
| 模擬 | 伺服器權威、客戶端預測與重播會透過明確的 Bevy ECS 狀態共用同一個模擬步驟。 |
| 網路 | 自訂 UDP 流量；QUIC 主機會提供瀏覽與中繼。主機負責模擬對戰。 |
接下來去哪裡
整個專案都是由 LLM 撰寫。

Third-party source code
--------------------------------------------------------------------------------
No third-party source code is vendored in this repository, and the build links

--------------------------------------------------------------------------------
References consulted during development
--------------------------------------------------------------------------------
These projects were read while working out how the original games behave. They
are named here because the reading happened, not because anything of theirs is
distributed: none of them is vendored, linked, bundled or otherwise shipped.
OpenAssetTools — https://github.com/Laupetin/OpenAssetTools
Open-source modding tools for older Call of Duty games. Its asset-structure
headers document the on-disk layouts IW4L reads. Licensed under GPLv3.
oat (iw4x-x64 fork of OpenAssetTools) — https://github.com/iw4x-x64/oat
The x64 fork, at revision 3a7442dee5ce040cfdb8da23fdb9fb525b5f743e, is the
tree whose IW4MS headers were read for the 64-bit FastFile layouts.
Licensed under GPLv3, like its upstream. No file in this repository is
compiled against, generated from or distributed with those headers.
IW4x — https://github.com/iw4x/iw4x-client
A custom client for Call of Duty: Modern Warfare 2 (2009), with dedicated
servers, security fixes and modding support. Read as a cross-reference for
asset and protocol behaviour. Licensed under GPLv3.
KisakCOD — https://github.com/SwagSoftware/KisakCOD
A Call of Duty 4 open-source reimplementation. Read as a cross-reference for
engine structure. IW4L targets IW4, so this is a neighbouring generation of
the same engine family, not the same codebase.
Ghidra — https://github.com/NationalSecurityAgency/ghidra
The software reverse engineering framework the original game binaries were
read with. A development tool: none of it, and none of its output, is
committed here or distributed with IW4L. Licensed under Apache 2.0.
--------------------------------------------------------------------------------
Game content
--------------------------------------------------------------------------------
No Call of Duty game data is contained in this repository or in any IW4L
release archive. IW4L reads game data from a copy of the game the user already
owns and has installed. Call of Duty, Modern Warfare, Black Ops, related
trademarks and all original game assets belong to their respective owners.
IW4L is not affiliated with, endorsed by or supported by them.
This fork (apex-movement branch) modifies IW4L to run Apex Legends-style
movement and weapons from ApexRuntime; modified and added files are listed
in the git history and README.
