## Problem
In the structure render pass, when **classic icons** are enabled the
inner icon glyph is tinted with a *darkened version of the player's fill
color* (`uIconDarken = 0.3`). When a player's territory color is already
dark, both the structure shape and its glyph render dark, so the icon
blends into the shape and the dark territory behind it — making it
effectively unreadable.
(With non-classic icons the glyph is already the light `uIconColor`, so
only the classic path was affected.)
## Fix
In `structure.frag.glsl`, when classic icons are active, compute the
fill's perceptual luminance and flip the glyph to the light icon color
(`uIconColor`, white by default) when the fill is too dark:
```glsl
vec3 glyphColor = uIconColor;
if (uIconDarken > 0.0) {
float fillLum = dot(fillColor.rgb, vec3(0.299, 0.587, 0.114));
glyphColor = fillLum < 0.25 ? uIconColor : darken(fillColor.rgb, uIconDarken);
}
```
The non-classic path is unchanged. The change is contained to the shader
— no new uniforms or plumbing.
## Notes
- The `0.25` luminance threshold is hardcoded in the shader to keep the
change surgical. It could be promoted to a `render-settings.json` knob
if preferred.

📋 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
