Mirrorwarfare

《靚影特務：關鍵催化》的跑酷，搭配《決勝時刻：現代戰爭 2》（2009）的槍械，在與機器人的自由混戰中。Mirrorwarfare 是 iw4L 的分支，一個以 Rust 撰寫、使用 Bevy 的開源 MW2 執行階段。它會從你已擁有的安裝中讀取兩款遊戲：本儲存庫中不包含任何一款遊戲的內容。

內容包含

  • Catalyst 移動（crates/movement_mec）：衝刺動量、沿牆奔跑與沿牆奔跑串接、蹬牆跳、爬牆與邊緣攀抓、牆上轉身（在牆上快速轉身並蹬出）、翻越、彈跳板、滑行、蜷身、落地滾翻與重落地分級。速度、高度與時機來自 Faith 的動畫狀態圖，該狀態圖從 Catalyst 自身的資料解碼而來；每個調校數值都記錄了其來源。
  • MW2 戰鬥：武器、兵種、連殺獎勵、FFA 遊戲模式與來自 iw4L 的機器人，並具備依動作而定的武器規則（沿牆奔跑時腰射，攀爬、翻越與滾翻時放下武器）。
  • Faith 的第三人稱動畫，從 Catalyst 解碼並重新定位到 MW2 身體上，讓其他玩家與機器人跑動、沿牆奔跑、翻越與滾翻時都像 Catalyst。
  • 跑酷遊樂場（testbox）：一座為此動作集打造的 80 × 80 公尺競技場，包含四個串接的橋段、一座 12 公尺高塔、14 個重生點，以及與你所見相符的碰撞。也可以使用 tools/mec 中的擷取器從 Catalyst 的城市切出競技場。
  • 確定性自動駕駛與測試框架：路線由競技場幾何生成，引擎內自動駕駛會依據遊戲狀態行駛這些路線，重複執行在 tick 上完全一致，且此框架會檢查移動、載入、效能、機器人與穩定性。

Catalyst 移動也能在原始 MW2 地圖上搭配 IW4L_MOVEMENT=mec 執行。

需求

Windows，並具備：

  • 《決勝時刻：現代戰爭 2》（2009）多人遊戲，透過 Steam 安裝。
  • 《靚影特務：關鍵催化》，透過 Steam 或 EA app 安裝。僅在需要 Catalyst 的第三人稱動畫與切出城市競技場時才需要；跑酷遊樂場不需要它。
  • Rust 與 MSVC 建置工具、uv 與 git。
  • 如果你要擷取 Catalyst 資料，簽出目錄旁約需 45 GB 可用空間。

快速開始

cargo build --profile play -p launcher         # ~15 min the first time, ~2 min after
uv run scripts/mec-testbox.py                  # writes the Parkour Playground to ..\mec-arenas\testbox
.\Mirrorwarfare.cmd -Arena testbox -Bots 0     # practise on your own
.\Mirrorwarfare.cmd -Arena testbox -Bots 7     # FFA with bots

Mirrorwarfare.cmd 會執行此簽出目錄自身的建置（target\play\iw4l.exe，或 -Exe），透過 Steam 找到 MW2 並開始一場對戰。-NoSound、-Spawn（跳過兵種選擇）、-Menu 與 -List 也可使用。從遊戲選單：Private Match → Game Setup → Change Map → CATALYST，Game Setup 中會有一列 BOTS。

Catalyst 資料（選用）： powershell -ExecutionPolicy Bypass -File tools\mec\setup.ps1 會找到 Catalyst，將其資料傾印到簽出目錄旁，將 Faith 的動畫解碼為 ..\mec-anims，並切出城市競技場。此流程可續行；-DryRun 會顯示計畫。沒有動畫包時，遊戲會退回原始 MW2 動畫。

控制

輸入 動作
W 奔跑；速度約在 3 秒內建立（沒有衝刺鍵）
Space 向上：跳躍、沿牆奔跑（以斜角撞向牆面）、爬牆（直直撞向牆面）、邊緣攀抓、翻越、彈跳板
C 向下：奔跑時滑行、在空中蜷身、落地時按住可落地滾翻
Q 180° 快速轉身，也可在爬牆期間於牆上使用以向後蹬出
滑鼠 MW2 武器：射擊、瞄準（沿牆奔跑期間不可）、裝填 R、近戰 V、手榴彈 F / G

在主控台（~）輸入 thirdperson 以觀看身體動畫。

如何打造

  • 引擎： iw4L 提供 MW2 資源載入、渲染、具伺服器權威與客戶端預測的網路程式碼、遊戲腳本（GSC）與機器人。Mirrorwarfare 新增競技場套件（crates/asset_mec），嫁接在原始地圖上以取得其天空、太陽與材質。
  • Catalyst 資料： Frostbite superbundle 由 tools/mec 中的 Python 工具傾印與解析（EBX、網格集、材質、Havok 與世界放置）。ANT 動畫庫由 tools/mec/antbank.py 與 antanim.py 解碼：狀態圖、時序視窗、根運動與片段。
  • 移動與動畫： movement_mec 依據解碼資料實作 Faith 的動作集，在模擬步驟內執行並隨快照傳輸。mec_anim 與 render_anim 將 Catalyst 片段重新定位並播放於遠端身體上。
  • 測試： tools/harness（run.py、showcase.py、determinism.py）使用 autopilot 主控台指令驅動遊戲。移動細節、資料來源與限制請見 MIRRORWARFARE.md，主控台指令請見 docs/RUN.md。

本專案幾乎完全由 LLM 撰寫，就如同它所建構於其上的 iw4L。

已知限制

  • 第三人稱並非完全 1:1：快速轉身與長距離翻越使用替代品（其片段使用尚未解碼的編解碼器），沒有手部或腳部 IK，且步槍在全身動作期間會隨著手部擺動。
  • Catalyst 的城市競技場僅帶有基礎色、法線與高光貼圖及烘焙光照；Catalyst 自身的材質、玻璃與全域光照為近似處理。
  • 僅有自由混戰經過調校。機器人透過嘗試而非規劃來尋找跑酷路線。
  • 機器之間的線上遊玩未經測試；所有對等端都必須執行相同建置。

法律

Mirrorwarfare 是非官方粉絲專案。它不隸屬於 Electronic Arts、DICE、Activision 或 Infinity Ward，也未受其背書。Mirror’s Edge、Call of Duty 與 Modern Warfare 為其各自所有者的商標。你需要自己擁有兩款遊戲的副本；本儲存庫不包含任何遊戲程式碼、資源或擷取資料，且工具會讀取你的安裝而不修改它們。Catalyst 資料僅從已安裝檔案讀取；未繞過或修改任何 DRM。

致謝與授權

建構於 iw4L 之上，其致謝 OpenAssetTools 及其 iw4x-x64 fork、IW4x、KisakCOD 與 Ghidra。Catalyst 工具建構於 Frostbite-Scripts（MIT）、FrostyToolsuite、AssetBankPlugin 與 IceBloc。

依 Apache 2.0 授權，如同 iw4L，除非檔案另有聲明：tools/mec/antanim.py 與 tools/mec/antbank.py 為 GPL-3.0-only（tools/mec/LICENSE-GPL-3.0），因為動畫解碼器移植自 AssetBankPlugin，而 tools/mec/fbebx.py 為 MIT，衍生自 Frostbite-Scripts。這些是獨立的 Python 工具；遊戲本身不包含它們。重新散布時請保留必要的姓名標示與隨附字型授權文本；請見 NOTICE。

      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You

          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its

          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

   END OF TERMS AND CONDITIONS
