## What Notify a player when one of their trade ships is captured. The alert appears in the **less-important (top) events tier** and is gated behind a new in-game setting (on by default). ## Why Previously there was no notification to the player who *lost* a trade ship — only the capturer got a transient +gold pip on the ship's arrival. This surfaces the loss to the victim, while letting players opt out if they find it noisy. ## Changes - **`src/core/execution/TradeShipExecution.ts`** — On capture detection, emit a display message (`events_display.trade_ship_captured`, type `UNIT_DESTROYED`) to the original owner. Fires once, guarded by the existing `wasCaptured` flag. `UNIT_DESTROYED` is not a Tier-1 type, so it lands in the top/less-important tier. - **`src/client/hud/layers/EventsDisplay.ts`** — Suppress the message when the setting is off, following the existing key-based filter pattern. - **`src/core/game/UserSettings.ts`** — New `tradeShipCapturedEvents()` getter (default `true`) + `toggleTradeShipCapturedEvents()`. - **`src/client/hud/layers/SettingsModal.ts`** — New toggle in the in-game settings modal. - **`resources/lang/en.json`** — New `events_display.trade_ship_captured` and `user_setting.trade_ship_captured_label`/`_desc` keys. - **`tests/core/executions/TradeShipExecution.test.ts`** — Tests that the notification is sent to the original owner with the right args and only once across ticks. ## Notes - The setting is gated client-side (in `EventsDisplay`), keeping `src/core` free of client-local localStorage settings — consistent with how display events are already filtered there. - Reused `MessageType.UNIT_DESTROYED` (red/"loss" styling) rather than adding a new message type, to keep the change minimal. Happy to add a dedicated type/color if preferred. ## Testing - `npx vitest tests/core/executions/TradeShipExecution.test.ts --run` — 7 passed - lint clean, no type errors 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>

Install dependencies
npm run instDo NOT use
npm installnornpm ibut instead use ournpm run inst. It runs the safernpm ci --ignore-scriptsto install dependencies exactly according to the versions inpackage-lock.jsonand doesn't run scripts. This can prevent being hit by a supply chain attack.
🎮 Running the Game
Development Mode
Run both the client and server in development mode with live reloading:
npm run dev
This will:
- Start the webpack dev server for the client
- Launch the game server with development settings
- Open the game in your default browser (to disable this behavior, set
SKIP_BROWSER_OPEN=truein your environment)
Client Only
To run just the client with hot reloading:
npm run start:client
Server Only
To run just the server with development settings:
npm run start:server-dev
Connecting to staging or production backends
Sometimes it's useful to connect to production servers when replaying a game, testing user profiles, purchases, or login flow.
To replay a production game, make sure you're on the same commit that the game you want to replay was executed on, you can find the
gitCommitvalue viahttps://api.openfront.io/game/[gameId]. Unfinished games cannot be replayed on localhost.
To connect to staging api servers:
npm run dev:staging
To connect to production api servers:
npm run dev:prod
