COD Pattern

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.

Commands and Entrypoints

`/cdp` Commands

* `/cdp screen` * Opens the backpack/loadout UI (debug entrypoint). * `/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. * `/cdp map spawn <list|add|remove|clear> ...` * Manages team spawn points and dynamic respawn candidates. * `/cdp map endtp <show|set|clear> <map> [pos]` * Manages match-end teleport points.

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.

Default Parameters in `tdm_rules/config.json`

| Field | Default | Description | |---|---:|---| | `timeLimitSeconds` | `420` | Match duration in seconds | | `scoreLimit` | `75` | Kill score to win | | `invincibilityTicks` | `30` | Post-respawn invincibility ticks | | `respawnDelayTicks` | `40` | Respawn delay ticks | | `warmupTimeTicks` | `400` | Warmup duration ticks | | `preGameCountdownTicks` | `200` | Pre-game countdown ticks | | `blackoutStartTicks` | `60` | Countdown blackout ticks | | `deathCamTicks` | `30` | Death cam duration ticks | | `minPlayersToStart` | `1` | Minimum players required to start | | `votePercentageToStart` | `60` | Start vote pass threshold (%) | | `votePercentageToEnd` | `75` | End vote pass threshold (%) | | `combatRegenDelayTicks` | `120` | Delay before regen starts after taking damage (ticks) | | `combatRegenHalfHeartsPerSecond` | `5.0` | Half-hearts restored per second while regenerating | | `allowJoinDuringPlaying` | `true` | Allow joining during active match | | `joinAsSpectatorWhenPlaying` | `true` | Join as spectator during active match | | `maxTeamDiff` | `1` | Max allowed team size difference | | `markerFocusHalfAngleDegrees` | `30.0` | Enemy health-bar focus cone half-angle (degrees) | | `markerFocusRequiredTicks` | `20` | Ticks required in the focus cone before the enemy health bar appears | | `markerBarMaxDistance` | `96.0` | Max distance for enemy health-bar detection (blocks) | | `markerVisibleGraceTicks` | `3` | Anti-flicker grace ticks while the enemy health bar remains visible |

Compatibility and Dependencies

* Optional Integrations: `1.20.1` * Optional Integrations: `47.4.0+` * Optional Integrations: `17` * Optional Integrations: * TaCZ `1.1.6+` * Optional Integrations: * 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
