## What Adds a second transport-ship trail style, **transition**, alongside the existing **gradient** (#4454). Where `gradient` paints a spatial band of colors along the trail, `transition` makes the whole trail one color at a time, cross-fading through the color list over time. ```json "attributes": { "type": "transition", "colors": ["#002aff", "#4805ff"], "frequency": 1 } ``` ## How - **Schema** ([CosmeticSchemas.ts](src/core/CosmeticSchemas.ts)) — `TransportShipTrailAttributesSchema` is now a discriminated union on `type`: - `gradient`: `{ colors, colorSize, movementSpeed }` - `transition`: `{ colors, frequency }` — `frequency` = color changes per second. - **Renderer** — the effect texture gained a `styleId` discriminator (row 1's alpha; 0 = gradient, 1 = transition), with the gradient scalars shifted down a row. - [WebGLFrameBuilder.ts](src/client/WebGLFrameBuilder.ts) encodes `styleId` + the style's scalars. - [trail.frag.glsl](src/client/render/gl/shaders/map-overlay/trail.frag.glsl): for `transition`, the trail color is `mix(colors[i], colors[i+1], fract(t))` with `i = floor(uTime · frequency) mod count` — one color step every `1/frequency` seconds. - **Store/picker swatch** ([EffectPreview.ts](src/client/components/EffectPreview.ts)) — the swatch is now a `<trail-swatch>` Lit element. For `transition` it cross-fades through the colors via the Web Animations API, timed to match the shader (each step `1/frequency` s); gradient/solid stay static. The animation is canceled on disconnect. ## Notes - Animation is render-only (local time) — no simulation/determinism impact. - `gradient` swatches remain static (they don't scroll like the in-game trail) — easy to add later if wanted. ## Testing - `tsc --noEmit`, ESLint, Prettier, `build-prod` all clean. - Schema tests cover the transition member (parse + required `frequency`); 95 tests pass. - The animated swatch is visual-only (no automated coverage) and not yet verified in a running store. 🤖 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
