COD Pattern

• *Release Status: Beta. Validate in a staging environment before production deployment, and back up world data/configuration first.

Overview

COD Pattern is built around TaCZ + an embedded FPSM-compatible core, providing a COD-like workflow for:

• Loadout presets and respawn equipment distribution
• In-match weapon refit with attachment presets
• Frontline / TeamDeathMatch rooms, maps, and match flow
• Localized UI and system messages (zh_cn / zh_tw / en_us / ja_jp)

The project follows a server-authoritative design with client synchronization to keep multiplayer state consistent.

Main Features

1) Loadout Management and Equipment Distribution

• Supports create/clone/rename/delete/select operations for loadouts, up to 10 per player.
• Each loadout contains four slots: primary / secondary / tactical / lethal.
• Loadout-related UIs use a fixed text-scaling baseline across different GUI Scale settings to keep readability more consistent.
• Default loadout names, clone suffixes, and equipped notifications are now localized by client language.
• On respawn, the selected loadout is distributed automatically (normal flow applies to joined room/match players).
• Player loadout/filter data is persisted on server side and synced on login.
• Admin commands can force immediate distribution for all online players or selected targets.

2) In-Match Weapon Refit and Attachment Presets

• Supports slot-level editing for primary, secondary, and throwable slots from the loadout UI.
• Uses TaCZ weapon capabilities, with server-side validation and persistence.
• Attachment presets are now stored directly inside the loadout config by loadout id and slot.
• Supports result feedback and rollback handling to reduce client/server state drift.

3) Rooms, Maps, and Match Flow (Embedded FPSM Compatibility Layer)

• Adds a unified room entry in pause menu for room list, join/leave, and team selection.
• Supports both frontline and teamdeathmatch under the same room system, map data model, and persistence flow.
• Maps now support area creation, spawn-point setup, match-end teleport setup, and persistence.
• TDM room screens use the same fixed text-scaling baseline across different GUI Scale settings for more consistent list/panel/button readability.
• Supports auto team assignment with balance constraints (maxTeamDiff).
• Supports ready state, start vote, and end vote with threshold and timeout logic.
• Full phase pipeline: WAITING -> COUNTDOWN -> WARMUP -> PLAYING -> ENDED.
• teamdeathmatch includes dynamic respawn candidates and spawn safety validation.
• Includes kill feed, score tracking, respawn delay, invincibility frames, combat regen, death cam, HUD phase feedback, ally/enemy highlights, and enemy health bars.
• Exports JSON match records automatically when a match ends.

4) Filtering, Compatibility, and Localization

• Primary/secondary category filtering via primaryWeaponTabs and secondaryWeaponTabs.
• Gunpack namespace blocking and exact weapon blacklist support via blockedItemNamespaces / blockedWeaponIds.
• Attachment namespace blocking and exact attachment blacklist support via blockedAttachmentNamespaces / blockedAttachmentIds.
• Throwable and ammo multiplier controls via throwablesEnabled and ammunitionPerMagazineMultiple.
• Optional integrations for LR Tactical and Physics Mod with graceful fallback when absent.
• Includes compatibility handling for tacz-addon 1.1.6 in backpack refit flow to prevent unload-button lockups.
• TaCZ native refit UI is globally disabled and redirected to the COD Pattern backpack refit flow.
• Bundles zh_cn / zh_tw / en_us / ja_jp language resources for core UI, notices, and error messages.

• /cdp update
  • Syncs weapon filter and loadout config to all online players (OP required).
• /cdp distribute [target]
  • Forces equipment distribution for all online players or selected players (OP required).

/cdp map Command Chain

• /cdp map list [type]
  • Lists registered game types or maps under a given type.
• /cdp map create <frontline|teamdeathmatch> <name> <from> <to>
  • Creates a map area and persists it immediately.
• /cdp map delete <type> <name>
  • Removes a map and its persisted data.

Configuration

Server configuration is stored under world save path: serverconfig/codpattern/

• backpack_rules/backpack_config.json
  • Player loadout data (JSON).
  • Attachment presets are now embedded on each loadout slot via the attachmentPreset field.
• backpack_rules/weapon_filter.json
  • Weapon filter config (JSON).
  • Key fields:
    • primaryWeaponTabs / secondaryWeaponTabs
    • blockedItemNamespaces
    • blockedWeaponIds (format: namespace:gunid)
    • blockedAttachmentNamespaces
    • blockedAttachmentIds (format: namespace:attachmentid)
    • throwablesEnabled
    • ammunitionPerMagazineMultiple
• tdm_rules/config.json
  • TDM runtime parameters (time, score, respawn, voting, join policy, balance policy).
  • In-match enemy/ally display is now fixed to highlights plus enemy health bars; the old marker-dot style toggle has been removed.
• tdm_match_records/
  • Exported match records (.json) after each match.
• Legacy paths backpackconfig / filterconfig / attachment_preset/ / tdmconfig/
  • Deprecated and no longer read by this version; existing worlds require manual migration.

Compatibility and Dependencies

• Minecraft: 1.20.1
• Forge: 47.4.0+
• Java: 17
• Required Dependencies:
  • TaCZ 1.1.6+
• Embedded Component:
  • FPSM-compatible core (no external fpsmatch.jar required)
• Optional Integrations:
  • LR Tactical (throwable/melee content path)
  • Physics Mod (ragdoll/retained death entity presentation)
  • tacz-addon 1.1.6 (backpack refit unload flow compatibility included)

Deployment Notes

• Non-forced distribution applies only to players joined in room/match flow.
• If no match-end teleport point is configured, end phase warns but does not auto-teleport back.
• If tacz-addon is enabled and attachment unload behaves abnormally in refit UI, ensure /gamerule liberateAttachment false.
• Before production rollout, verify:
  • tdm_rules/config.json values match your server pacing
  • backpack_rules/weapon_filter.json matches your gunpack filtering policy
  • maps include team spawn points and a match-end teleport point
