## Problem Changing the ocean/water color in **Graphics settings** repaints the terrain — and any water tiles created by water nukes (land → water) snap back to their original land appearance. ## Root cause `TerrainPass` captures the `terrainBytes` buffer at construction and reuses it in two places: - `setOceanColor()` does a **full** terrain texture re-upload from `terrainBytes` when the ocean color changes. - `applyTerrainDelta()` applies live land→water nuke conversions, but only wrote to the **GPU texture** — never back into `terrainBytes`. So the CPU buffer stayed frozen at the map's original terrain. Changing the ocean color rebuilt the whole texture from that stale buffer, reverting every nuke crater to land. ## Fix Write each delta byte back into `terrainBytes` inside `applyTerrainDelta()`, so the buffer stays the live source of truth and full re-uploads reflect conversions. ```ts this.terrainBytes[ref] = bytes[i]; ``` The indexing already lines up — `terrainBytes` is indexed by linear ref (`y * mapW + x`), the same `ref` the delta loop iterates. The buffer is only otherwise read once at construction by `RailroadPass`/`TerrainPass` to seed GPU textures (which copy), so mutating it has no side effects elsewhere. ## Testing The WebGL passes have no unit-test harness (they need a live GL context), so this isn't covered by an automated test. Verified by reasoning through the data flow; can confirm in-game by nuking land into water and then changing the ocean color. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

📋 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
