Resolves #4401 NOTE: While this PR is an improvment, the Indian subcontinent crash IS NOT caused by >253 water components, as the map only has ~15 water components. ## Description: Fixes a critical browser tab crash ("Aw, Snap! Something went wrong") when loading the game on the new Indian Subcontinent map (or any map with >= 253 water components) in Solo Mode. ### Technical Cause: 1. When a map contains >= 253 disconnected water components, the array mapping tiles to component IDs is dynamically promoted from a Uint8Array to a Uint16Array. 2. This promotion upgrades the land sentinel LAND_MARKER from 0xff (255) to LAND_MARKER_WIDE (0xffff / 65535). 3. The BFS local search filter in AStarWaterHierarchical had a hardcoded sentinel check: (t: TileRef) => this.graph.getComponentId(t) !== LAND_MARKER (evaluating against 255). 4. On promoted maps, land tiles (65535) matched this check as water. The local BFS then traversed the entire landmass of the map, resulting in CPU exhaustion and memory/stack overflows that crashed the rendering process. ### Solution: Changed the hardcoded sentinel check to query the map's terrain directly via this.map.isWater(t). This makes the check immune to any component ID promotions or sentinel representation upgrades. Verified that the existing water pathfinding test suite passes successfully. ## Please complete the following: - [ ] I have added screenshots for all UI updates (N/A) - [ ] I process any text displayed to the user through translateText() and I've added it to the en.json file (N/A) - [x] I have added relevant tests to the test directory (Existing tests in tests/core/pathfinding/PathFinding.Water.test.ts cover water pathfinding behavior and run successfully) ## Please put your Discord username so you can be contacted if a bug or regression is found: blontd6

🚀 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
