## What Structure **level numbers** now render in the **`round_6x6_modified`** bitmap font by default (matching the old PIXI-based `StructureLayer` / `v31`), with a graphics setting to switch back to the smooth `overpass-bold` MSDF font. Two commits: 1. **Default to the classic bitmap font** — `StructureLevelPass` drew level digits from the `overpass-bold` MSDF atlas (the one `NamePass` uses for player names); switch the default to the `round_6x6_modified` pixel font (white digits with a baked-in dark outline). 2. **Add a runtime toggle** — load both fonts and switch between them live via a new `Classic level numbers` graphics setting. ## How - `StructureLevelPass` loads both atlases up front and selects one per frame from `settings.structureLevel.classicFont`, re-laying-out the digits when the toggle flips (digit advances differ between the fonts). The fragment shader is a single program with a `uClassic` branch: direct bitmap sample (white fill + baked outline) vs. MSDF median + synthesized outline. - New override `structure.classicNumbers` in `GraphicsOverrides` (default `true` = classic), applied onto `settings.structureLevel.classicFont` in `applyGraphicsOverrides` — so it switches live, like the existing colorblind/classic-icons toggles. - `GraphicsSettingsModal` gets a `Classic level numbers` toggle next to `Classic icons` (with `en.json` strings). ## Testing - `tsc --noEmit`, ESLint, Prettier, and `npm run build-prod` all pass. - Ran the game headless, built/upgraded cities to level 2–3, and confirmed: the classic toggle renders the pixel font, flipping it renders the smooth MSDF font, and flipping back restores the pixel font — switching live with no shader errors. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>

🚀 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
