## Description: Adds a new `structures` cosmetic effect type: an equippable effect that recolors the owner's structure icons (City, Port, Factory, Defense Post, SAM Launcher, Missile Silo) with gradient or transition color styles. The effect is **shown while the owner's territory is hovered** — structures otherwise keep their normal player colors, so the map stays readable. **Cosmetics / selection** - `StructuresEffectAttributesSchema` (`CosmeticSchemas.ts`): its own discriminated union (`gradient` / `transition`) — structurally identical to the trail attributes today, but structures aren't trails, so it's a separate schema free to diverge. - Slot = the effectType itself: `effectTypeForSlot` is generalized to map any non-nukeExplosion effect type to itself, so server privilege checks (`Privilege.ts`), client selection, and persistence all work with no per-type code. - Effects tab, Default tile, and the store preview (shared color swatch) come from `EFFECT_TYPES`; the only UI addition is the `effects.type.structures` label in `en.json`. **Rendering** - The shared per-player effect palette grows from 2 to 3 blocks (`EFFECT_PALETTE_BLOCKS`; structures = block 2, pinned by a build-breaking guard). `syncPlayerEffects` resolves the `structures` selection through the same `writeEffectEntry` used by trails. - `StructurePass` binds the effect texture plus `uTime` and `uHoverOwner` (fed from the existing `HoverHighlightController` → `setHighlightOwner` path, now forwarded to the pass). - `structure.frag.glsl` recolors the **fill only** — the border keeps the player color for ownership legibility; alt view and construction gray bypass the effect entirely. - Style semantics: - `gradient` — the palette spans each icon's diagonal once (a visible gradient across the shape), sliding one full cycle every `colorSize · 4 · count / movementSpeed` seconds (the trail-equivalent pace; world-space banding like the trail's would put a whole icon inside one band and read as a flat color) - `transition` — the whole icon is one color at a time, cross-fading at `frequency` colors/s - Glyph contrast: the inner icon's black/white decision is now a smooth luminance fade (`smoothstep(0.25, 0.45)`) instead of a hard flip at 0.25, so animated fills cross-fade the glyph instead of snapping it between black and white. ## Please complete the following: - [ ] I have added screenshots for all UI updates - [x] I process any text displayed to the user through translateText() and I've added it to the en.json file - [x] I have added relevant tests to the test directory 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Fable 5 <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
