Zixer1andGitHub 95840a2074 Doomsday Clock: judge teams against the same bar as solo sides (#4624)
**Add approved & assigned issue number here:**

Resolves #(to be filed — happy to open the matching issue; flagging
directly since this is live in prod team lobbies)

## Description:

**Bug.** In Team mode the Doomsday Clock threshold is scaled by the
team's *alive* headcount (`base × members.length`, capped at the whole
map). In real team lobbies this breaks the mechanic:

- With ~16 players per team, wave 1 already demands `4 % × 16 = 64 %+`
of the map per team while all humans combined hold ~35 % (bots own the
rest). Every non-leading team is skulled ~1 minute into wave 1 and
drained to the 5 % floor ~90 s later — even on **slow**, whose squeeze
is designed to run to 45:00. The game is decided by whoever leads at
grace-end.
- The bar/forecast **drops when a teammate dies** (players see "will
rise to 68 %" → "44 %" mid-game), and disconnected-but-alive teammates
silently inflate it.
- Past the 100 % cap, the per-capita scaling stops meaning anything
anyway.

**Evidence.** Prod game `JEUieLzK` (`Team, playerTeams: 4, 69 players,
doomsdayClock slow, bots: 400, no timer`): ended **16:47** via the 95 %
team-domination check. From the archived record: 25 deaths before 10:00,
only 8 after — the drain cripples rather than kills, so the collapse is
invisible in death stats but decisive in outcome. Reconstruction with
the real schedule + drain constants: every non-leading team skulled
~11:00–11:30 and pinned at the floor by ~12:30; the crown-exempt leader
rolled to 95 % by 16:47.

**Why flat is correct.** The wave levels encode a viable-**side** count
— `floor(100 / wave%)` sides fit above the bar (25 → 11 → 6 → 3 → 2 →
1). Elimination and victory happen at side granularity (a team is out
when the whole team is out; the winner is a team), so the slots must be
counted in sides. A team now faces exactly the bar a solo player faces,
judged on its combined territory — and each speed preset means the same
thing in teams as it does in FFA.

**Changes:**

- `DoomsdayClock.ts`: remove `doomsdayClockSideRequiredTiles`; the sim
and the HUD both use `doomsdayClockRequiredTiles` (hoisted out of the
per-side loop — it no longer varies per side).
- `DoomsdayClockExecution.ts`: flat per-side bar; comments updated.
- `DoomsdayClockPanel.ts`: drop `scalePct`/headcount from the readout —
the zone forecast becomes one universal, monotonic number for every
player (fixes the 68 % → 44 % whipsaw). `sideStats` → `sideTiles`.
- Tests: headcount-scaling expectations replaced with flat-bar +
death-invariance regression tests.

(History note: an earlier commit restricted team lobbies to normal/fast
presets; it was reverted in-branch — with the flat bar the presets carry
the same meaning as in FFA, so the full rotation stays. Squash-merge
leaves the fix only.)

FFA behaviour is unchanged throughout (sides of size 1: flat ≡ current).
Deterministic integer math untouched (strictly fewer ops). `npm test`
fully green.

Rule comparison on `JEUieLzK`'s shape (real death ticks + constants;
modeled share trajectories):

| rule | trailing teams skulled | all non-leaders at 5 % floor |
|---|---|---|
| current (× alive) | 11:01–11:27 | **12:34** ← matches the real 16:47
blowout |
| flat per-side bar | 26:01–30:42 | 31:49 (late-game backstop, as
designed) |

## Please complete the following:

- [ ] I have added screenshots for all UI updates — _no layout/element
changes; the existing readout shows unscaled values (numbers only)_
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file — _no new strings; existing
`doomsday_clock.*` keys reused with the same params_
- [x] I have added relevant tests to the test directory

🌟 Features

  • Real-time Strategy Gameplay: Expand your territory and engage in strategic battles
  • Alliance System: Form alliances with other players for mutual defense
  • Multiple Maps: Play across various geographical regions including Europe, Asia, Africa, and more
  • Resource Management: Balance your expansion with defensive capabilities
  • Cross-platform: Play in any modern web browser

📋 Prerequisites

  • npm (v10.9.2 or higher)
  • A modern web browser (Chrome, Firefox, Edge, etc.)

🚀 Installation

  1. Clone the repository

    git clone https://github.com/openfrontio/OpenFrontIO.git
    cd OpenFrontIO
    
  2. Install dependencies

    npm run inst
    

    Do NOT use npm install nor npm i but instead use our npm run inst. It runs the safer npm ci --ignore-scripts to install dependencies exactly according to the versions in package-lock.json and 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=true in 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 gitCommit value via https://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

🛠️ Development Tools

  • Format code:

    npm run format
    
  • Lint code:

    npm run lint
    
  • Lint and fix code:

    npm run lint:fix
    
  • Testing

    npm test
    

🏗️ Project Structure

  • /src/client - Frontend game client
  • /src/core - Deterministic game simulation
  • /src/server - Backend game server
  • /resources - Static assets (images, maps, etc.)
