## Summary The game simulation runs **client-side**, so the server can't directly see what's happening in a running game. This adds a way for the admin bot to observe a live game: clients report a live stats snapshot every ~10s, the server reaches consensus on it (reusing the winner's vote mechanism), and a new admin-bot endpoint serves it. ## How it works 1. **`LiveStatsController`** (client) emits a snapshot every **100 turns** (~10s at 100ms/turn) — only deterministic sim values, with players sorted by clientID, so in-sync clients produce an identical payload. 2. The snapshot is sent as a new **`live_stats`** wire message wrapping a `LiveStats` object (`turn` + per-human-player `tilesOwned`/`troops`/`gold`/`isAlive`/`team`). 3. **`GameServer.handleLiveStats`** tallies a per-turn **IP-weighted majority vote** — the same consensus the winner uses — and keeps the latest agreed snapshot. 4. **`GET /api/adminbot/game/:id/stats`** returns it, enriched with usernames the server already holds. `liveStats` is `null` until the first consensus. The winner's vote tally was extracted into a small reusable **`VoteRound`** (`src/server/VoteTally.ts`) and is now used for both winner and live-stats consensus. Names are deliberately **excluded** from the voted payload (they vary per client under name anonymization, which would break exact-match consensus); the server joins `clientID → username` instead. ## Changes - `src/server/VoteTally.ts` *(new)* — reusable IP-weighted `VoteRound` - `src/core/Schemas.ts` — `PlayerLiveStatsSchema`, `LiveStatsSchema`, `ClientSendLiveStatsSchema` + unions - `src/client/controllers/LiveStatsController.ts` *(new)* — per-100-turn snapshot reporter - `src/client/Transport.ts` — `SendLiveStatsEvent` + sender - `src/client/hud/GameRenderer.ts` — register the controller - `src/server/GameServer.ts` — refactor winner onto `VoteRound`; add live-stats consensus + `liveStats()` accessor - `src/server/AdminBotRoutes.ts` — `GET …/stats` endpoint ## Testing - **Unit:** `tests/server/VoteTally.test.ts` (majority/dedup/ties), `tests/server/LiveStats.test.ts` (consensus, disagreement, per-client dedup, stale-turn rejection, turn advance, out-of-sync exclusion, + endpoint 200/404/400). Full suite green (`npm test`), typecheck + lint clean. - **Manual e2e** against the dev server: created an admin-bot game, joined it in a browser, force-started via `toggle_game_start_timer`, and confirmed `GET …/stats` returned the consensus snapshot with username enrichment and an advancing `turn`. Also verified wrong-worker → 400 and missing-key → 401. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
OpenFront.io is an online real-time strategy game focused on territorial control and alliance building. Players compete to expand their territory, build structures, and form strategic alliances in various maps based on real-world geography.

📋 Prerequisites
- npm (v10.9.2 or higher)
- A modern web browser (Chrome, Firefox, Edge, etc.)
🚀 Installation
-
Clone the repository
git clone https://github.com/openfrontio/OpenFrontIO.git cd OpenFrontIO -
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
