## Description: Nations always rushed nuked (fallout) TerraNullius instead of retaliating or attacking enemies. The bug needed two commits to compose: **#3786** introduced `PlayerImpl.nearby()` (renamed from `neighbors()`) and wired it into the early expansion gate in `AiAttackBehavior.maybeAttack()` via a second disjunct: ```ts const hasNonNukedTerraNullius = border.some((t) => !hasOwner(t) && !hasFallout(t)) || // already filtered playerNeighbors.some((n) => !n.isPlayer()); // via nearby() ``` The first disjunct correctly excludes fallout, but the second one went through `nearby()`, whose direct-neighbor loop never filtered fallout (unlike the `shoreReachableNeighbors()` sibling introduced in the same commit). So a nation bordering directly-adjacent nuked TN reported it as plain TerraNullius and set the gate true. The bug stayed **dormant** because #3786 also introduced `hasLandBorderWithTerraNullius()` *with* a fallout filter, so `sendAttack(terraNullius())` still rejected nuked TN and the early `return` never fired. **#3814** removed the fallout filter from `hasLandBorderWithTerraNullius()` so the `nuked` strategy could capture fallout tiles. That unblocked the land path of `sendAttack`: now the early gate fired on nuked-only borders *and* `sendAttack` succeeded, pre-empting every attack strategy (retaliate, bots, assist, ...) on every difficulty. Fix: filter nuked (fallout) unowned tiles in `nearby()`'s direct-neighbor loop, making it consistent with `shoreReachableNeighbors()`. The early gate now only fires for non-nuked TerraNullius, and the `nuked` strategy still fires (and captures territory) when the nation has nothing better to do, preserving the behaviour #3814 intended. Added `tests/AiAttackBehaviorNukedTerritory.test.ts` covering: - `nearby()` excludes directly-adjacent nuked TerraNullius - `maybeAttack` retaliates against an incoming attacker instead of nuked TN - the early gate is bypassed when only nuked TN borders the nation - the `nuked` strategy still captures tiles when the nation is idle (Impossible and Easy difficulties) - `isUnitDisabled(MissileSilo)` short-circuits the `nuked` strategy ## Please complete the following: - [X] 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 ## Please put your Discord username so you can be contacted if a bug or regression is found: FloPinguin

🚀 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
