## Description:
Changes URL embeds within other platforms, e.g. Discord, WhatsApp & X.
Updates game URLs to `/game/<code>` instead of `/#join=<code>` (required
for embedded URLs). An added benefit of this is that you would be able
to change a url from `openfront.io/game/RQDUy8nP?replay` to
`api.openfront.io/game/RQDUy8nP?replay` (add api. In front) and be in
the right place for the API data.
Updates URLs when joining/leaving private lobbies
Appends a random string to the end of the URL when inside a private
lobby and options change - this is to force discord to update the
embedded details.
Updates URL in different game states to ?lobby / ?live and ?replay.
These do nothing other than being used as a _cache-busting_ solution.

# Pathfinding pt. 3
## Description:
This PR introduces final change to the pathfinding - path refinement. It
optimizes Line of Sight refinement by searching with for the best tile
with a binary search instead of linearly. And then spends the recovered
budget on better refinement of the first and last 50 tiles of the
journey - the place where user is most likely to look at. Additionally
this PR re-introduces magnitude check and makes the ships prefer sailing
close to the coast, but not too close.

## Performance
There is actually a severe performance impact of these changes. The path
initial path takes almost 2x as long to generate - this is because pre
processing can only do so much if the initial path is ugly. Luckily in
real gameplay we only need to do this calculation once per edge, so the
actual observed performance impact should be much smaller. Cache FTW.
| | No Cache | Cache |
| :--- | :--- | :--- |
| Before | 277.04ms | 208.58ms |
| After | 498.34ms | 264.27ms |
## DebugSpan
Small utility, it allows any code to be easily instrumented for
performance. The idea is the same as with [OTEL
Spans](https://opentelemetry.io/docs/concepts/signals/traces/). Produce
a span, create sub-spans, measure whatever you need. Works only when
`globalThis.__DEBUG_SPAN_ENABLED__ === true`, otherwise no-op.
Cool stuff, try it out:
```ts
// Convenient wrapper, small performance impact
return DebugSpan.wrap('add', () => a + b)
// Synchronous API, basically free
DebugSpan.start('work')
work()
DebugSpan.end()
// Create sub spans
DebugSpan.wrap('complex', () => {
const aPlusB = DebugSpan.wrap('add', () => a + b)
DebugSpan.set('additionResult', () => aPlusB) // Store data
return aPlusB * c
})
// Access spans, data and timing
const span = DebugSpan.getLast()
const compelxSpan = DebugSpan.getLast('complex')
console.log(complexSpan.duration, complexSpan.data['additionResult'])
```
These are virtually free and can be enabled on-demand **in production**
and available in the devtools. Under the hood devtools integration is
just a wrapper around [Performance
API](https://developer.mozilla.org/en-US/docs/Web/API/Performance_API).
For clarity data keys not prefixed by `$` are omitted from the
integration. Every key prefixed with `$` must be fully JSON
serializable.

## Pathfinding Refactor pt. 2
<img width="1536" height="1024" alt="image"

This is a follow-up to a previous PR introducing pathfinding changes.
This time, it introduces a complete refactor of `pathfinding` directory
and breakdown into composable pieces.
### Unified PathFinder interface
`PathFinder<T>` and `SteppingPathFinder<T>` are introduced to unify
**all** pathfinding across the application. First one exposes complete
path, while stepping variant allows the callee to iterate over the path
by calling `.next`. All pathfinders share this one common interface,
which makes them easy to use in any scenario -
`PathFinding.Water(game).search(from, to)`.
`SteppingPathFinder<T>` extends `PathFinder<T>` with an ability to
iterate over the path. It handles caching, storing current index and
invalidation. This allows the units to not care about the inner workings
of the pathfinder and just call `pf.next(current, target)` and receive
instructions on what to do next.
### Common entry point
All pathfinders are now exposed from common `PathFinding` entrypoint:
- `PathFinding.Water`
- `PathFinding.Rail`
- `PathFinding.Stations`
- `PathFinding.Rail`
Additional entry point is introduced for pathfinders which need to work
both in the worker, but also on the frontend, which lacks `Game`
interface. Currently only `UniversalPathFinding.Parabola` is available.
### Spatial Query
New module has been introduced close to `pathfinding` - `SpatialQuery`.
It aims to resolve any questions game may have about finding tiles
meeting criteria. Currently `SpatialQuery.closestShore(player, target)`
and `SpatialQuery.closestShoreByWater(player, target)` are available -
they help answering questions about naval invasion: "What is the best
landing location from user's click?" and "Which our tile should be used
to launch the transport ship?". Under the hood they use very similar
mechanics to pathfinding, so it felt right to put them close by.
### Modular architecture
Pathfinders now support transformers: `MiniMapTransformer`,
`ShoreCoercingTransformer`, `ComponentCheckTransformer`,
`SmoothingTransformer`. Transformers functions like a middleware in the
pathfinding chain. They wrap around the pathfinder and provide
additional functionality. This allows the pathfinder to focus on
actually finding the path instead of doing unrelated things.
Example chain for simple (A*) water pathfinding:
```ts
static WaterSimple(game: Game): SteppingPathFinder<TileRef> {
const miniMap = game.miniMap();
const pf = new AStarWater(miniMap);
return PathFinderBuilder.create(pf)
.wrap((pf) => new ShoreCoercingTransformer(pf, miniMap))
.wrap((pf) => new MiniMapTransformer(pf, game.map(), miniMap))
.buildWithStepper(tileStepperConfig(game));
}
```
The Pathfinder - here `AStarWater` - does not care about the conversion
between minimap and main map tiles. It also does not care if the source
or destination is a land tile. The transformers take care of that. The
pathfinder gets a set of valid coordinates and produces the path -
that's it.
Modular approach makes working on a particular set of utilities much
easier - for example map upscaling is handled consistently across all
pathfinders. Additionally, the pathfinders are not tied to the
particular map resolution used. Pass them a different map and they will
work the same.
### Algorithms
Algorithms used are neatly organized inside
`src/core/pathfinding/algorithms`. They are prefixed with the algorithm
name and suffixed with the use case. File without suffix exposes generic
version ready to traverse any graph with adapters. Specialized versions
either use an adapter or inline logic when performance is critical -
using adapters leads to 20-30% performance loss.
The directory includes `A*` and `BFS` but also other useful utils, such
as `AbstractGraph` used to generate... an abstract graph on top of the
tile map and `ConnectedComponents` helping to identify whether two tiles
are connected by a path without actually computing the path.
### Playground
The playground have been updated with new algorithms, including tweaked
very greedy `A*`.

src="https://github.com/user-attachments/assets/1f833651-0024-4299-bf86-882f5368358c"
/>
### Tests
Yeah, there are some, a little too many if I say so myself. But there
are no useless tests. I had to ensure refactored code works somehow
reliably. This PR comes with trust me bro guarantee, but I would
appreciate someone confirming **naval invasions, nukes (esp. MIRV) and
warships**.

### `NationAllianceBehavior`
- `isAlliancePartnerSimilarlyStrong()` now also checks for
`numTilesOwned`, should make it a bit easier to get alliances. The troop
calculation now also uses the players `outgoingAttacks` to make it feel
less random. OF-Discord-Humans complained.
- Rebalanced `checkAlreadyEnoughAlliances()` a bit
### `NationNukeBehavior`
- Don't save up for MIRV if they are disabled
- Don't try to throw atom bombs / hydros if they are disabled
- Hydro-Nations are allowed to throw atom bombs if they are under heavy
attack
- Rebalance `isUnderHeavyAttack()` a bit
- Increased perceived cost
### `NationEmojiBehavior`
- Fix multiple nations congratulated the winner instead of one
- Don't brag with our crown if the game is already over
### `DonateGoldExecution` & `DonateTroopExecution`

My first PR about the nation build order.
This one is a bit important for HumansVsNations.
- Nations build more SAMs in team games
- Nations build less factories if they have access to the ocean (instead
of focusing ports and factories with the same priority)

they share a border with someone they haven't allied
I'm planning to make the build order a bit different based on
difficulty.

### Refactor
- Moved `maybeSpawnWarship()` from `NationExecution` to
`NationWarshipBehavior`
- Moved `maybeAttack()` (and sub-methods) from `NationExecution` to

### Betrayal
- Added nice betrayal logic in `maybeBetray()`. Previously that method
was basically just a placeholder for a future implementation.
### Attacking
- Added `veryWeak()` attack strategy for hard and impossible difficulty
nations attack orders to target MIRVed players with higher priority
- Optimized the `weakest()` attack strategy so that nations don't attack
stronger players. This should make nation-attacks feel less random
(humans complained in discord)
- `findNearestIslandEnemy()` and `randomBoatTarget()` also no longer
returns stronger players
- `afk()` and `hated()` attack strategies no longer return MUCH stronger
players
- Several tiny refactorings, fixes and balance optimizations in
`AiAttackBehavior`

## Description:
Some FX animations were previously used as UI elements (e.g. nuke area,
naval invasion target, gold text).
This PR moves those animations to a dedicated UI layer.
Those UI elements handle correctly the current zoom level and remain
sharply rendered at all zoom levels.
The new UI layer can be disabled using the same setting that disables
the FX layer.
Performance-wise, this layer is equivalent to the FX layer, as it reuses
the same animations.
### Naval target
Don't scale with the zoom level, but has a minimum zoom level so the
targeted tile can still be easily highlighted by zooming
### Nukes
Has to scale because the size is set, but the border radius is not so
the area is more visible from afar.
### Popup text
Scale with zoom level, and stop showing when zoomed-out:

Resolves#2823
## Description:
When playing in single-player mode, if an NPC reaches 80% land control
before the player, the game enters a broken state where:
- The game clock stops
- Win checking stops permanently
- Even if the player later conquers 100% of land, victory is never
awarded
- The game becomes "stuck" in a zombie state.
This PR addresses this allowing Nations to be set as winners in single
mode, and in this case showing a "Nation {nation} has won" modal to the
user. This WinModal is the same as the "{player} has won", with the only
change being the title.
Nation wins in FFA, from the human player perspective:

## Pathfinding with HPA*
Hi! The primary objective of this PR is to replace per-tile A* with
hierarchical pathfinding - HPA*. In practice, this means we create an
abstract graph on top of the actual map with far fewer points and use it
to decide on general path structure. Only then we go back to tile-level
and build path between selected waypoints. This speeds up long distance
pathfinding by over 1000x in some cases. To make the review easier, it
comes with a benchmark and visual playground.

H part of HPA* means "hierarchical" and requires preprocessing.
This PR includes pre-processing as part inside `new Game()` constructor.
It takes about 135ms for `giantworldmap` on my machine, which increases
the effective initialization from ~95ms to ~230ms. This time could be
reduced in different ways, which are **out of scope** for this PR.
After confirming the initialization time is bearable on low-end devices,
I argue merging this PR as-is is acceptable tradeoff. It creates small
lag at the beginning of a round but pays for itself in the first minute
of the match.
## Nerdy details
**Architecture**
- HPA*-style hierarchical pathfinding
- 32×32 sectors on minimap with gateway nodes on borders
- Gateway graph built via BFS during preprocessing
- Water component optimization skips unreachable gateway pairs
- A* on gateway graph → local A* within sectors → Bresenham path
smoothing
- Minimap upscaling identical to currently used in MiniAStar
**Key Optimizations**
- Typed arrays instead of high-level primitives
- Stamp-based visited tracking (no need to recreate buffers, O(1)
clearing)
- Optional - enabled by default - caching of tile paths between gateways
- Line of sight smoothing for the final path
## Review Focus
Play with included tools, benchmark and visualization. Pathfinding
should be safe to merge as a black box - you do not need to understand
the details. Outcomes can be tested empirically in-game. Visualize (and
share!) edge cases with included playground. Confirm the 100x speedup is
real with benchmark.
If you plan to dive into the code, I suggest the following order:
- Pathfinding abstraction in `src/core/pathfinding/`
- Pathfinding tests in `tests/core/pathfinding/`
- NavMesh in `src/core/pathfinding/navmesh/` + integration with
`Game.ts`
- Benchmark in `tests/pathfinding/benchmark/`
Do not look at playground's code, it has been created with a clanker.
The design is 100% mine and I spent way too long polishing it, but I
haven't even once edited the code manually. There is probably no
abstraction whatsoever, just do not look at the code, let it play.
## Core Changes
#### Pathfinding (`src/core/pathfinding/navmesh/`)
- HPA* + refinement -> three phased pathfinding: A* over the graph ->
naive path -> refinement
- comes with A* and BFS optimized for for specific needs
#### Pre-Processing (`src/core/pathfinding/navmesh/`)
- identify water bodies to avoid pathfinding between disconnected nodes
- create high-level graph of gateways on top of tile map
#### Abstraction (`src/core/pathfinding/`)
- common `PathFinder` interface that can return full path and also act
as state machine (`.next()`)
- adapters for both new and legacy algorithm with fallback to legacy if
navigation mesh not available
#### Benchmark (`tests/pathfinding/benchmark/`)
- `npx tsx tests/pathfinding/benchmark/run.ts` - no guesswork, numbers
- `npx tsx tests/pathfinding/benchmark/run.ts --synthetic` - 1000s of
synthetic paths
- `npx tsc tests/pathfinding/benchmark/generate.ts` - generate more as
needed, test new maps
- includes ONE synthetic scenario to avoid PR bloat, generate more
locally / later
#### Playground (`tests/pathfinding/playground/`)
- `npx tsx tests/pathfinding/playground/server.ts` - visualize paths
with both new and legacy algorithm
## Benchmarks

## Description:
The new (awesome) nation emoji updates had a small bug in them when I
was playtesting with a friend where donating troops to them (a human
player) would result in the player automatically sending an emoji reply.
Sometimes these replies were negative-connotations like ❓ and 🥱, which
could impact how other players perceive their donation attempt. This PR
fixes that issue.

## Description:
Previously, the zod schemas for troop and gold donation allowed for
negative values which could open the game up to vulnerabilities through
undefined behavior in the future. We mitigate these vulnerabilities but
adding `.nonnegative` to the `DonateGoldIntentSchema` and
`DonateTroopIntentShcema` respectively. Today, code exists to prevent
this deeper in the codebase, but we should also prevent this earlier if
possible during intent validation.

## Description:
Added a public game modifier system. It causes that
5% of public games are played on the compact version of the map
10% of public games have "Random Spawn" activated
Percentages can easily get changed via `DefaultConfig`.
We can also easily add more modifiers.
Modifiers can stack, so in rare cases you will play on a compact map
with random spawn 😄
More variety!
### "Compact Map" modifier implementation
- With the "Compact Map" modifier the lobby max player count gets
reduced to 25% and only 25% of the regular bots and only 25% of the
regular nations will spawn (because the map has only 25% of its regular
size)
- In private lobbies and singleplayer the nation reduction happens too
(When "Compact Map" is enabled).
### Restrictions
- Duos/Trios/Quads team modes do not get Random Spawn (defeats the
purpose)
- Maps with smallest player count < 50 do not get Compact Map in team
games (not enough players after the reduction to 25%). I have calculated
all the possible max player counts.
### How it looks like
Random Spawn modifier:
<img width="528" height="183" alt="Screenshot 2026-01-06 194959"
src="https://github.com/user-attachments/assets/2f729da9-80c3-4548-8205-71129da2a76a"
/>
Very rare case: Two modifiers at the same time and only 10 max players
have been chosen from `[GameMapType.FaroeIslands]: [20, 15, 10]`.
Because of the 75% reduction in player count only 3 players are allowed
(3 is the minimum). I think its funny that you can play a 1v1v1 in rare
occasions 😄

src="https://github.com/user-attachments/assets/834326eb-df03-41b7-b1db-1efa3f1013b5"
/>
### Funny side-effect
Team games with random spawn. That will be interesting. No more "Who is
better in donating troops to the frontline". Instead you have to heavily
coordinate with your teammates.

## Description:
We didn't have a river map and we didn't have a map with a crazy size.
So I made a "Amazon River" map with a crazy size.
280 x 5536!
21 nations based on real locations.
Should be interesting gameplay because you don't have many attack
options, your only escape is the river.
The land tiles size is similar to the achiran and iceland map.

/>
Because the map is so wide, it looked really ugly stretched in the
thumbnails. So I added some CSS which removes the thumbnail stretching
of the Amazon River map. We can also use this logic for other thumbnails
which shouldn't get stretched.
In `Maps.ts`, `PublicLobby.ts` and `GameInfoModal.ts`.

Contributes towards the ongoing task of adding achievements: #2706
## Description:
Introduces a concept design and API implementation for singleplayer win
achievements. New row of ~5~ 4 medals is added to the map select screen
in the Singleplayer modal, one for each difficulty:
<img width="3132" height="779" alt="image"
src="https://github.com/user-attachments/assets/da8f0314-ccad-4f45-a03f-1beb46981301"
/>
In order to achieve a medal in a particular map, you must win the
singleplayer game (multiplayer and private match games don't count) in
the selected difficulty **without tampering with the options or
settings**. If any setting is changed from the default, regardless of
the difficulty, you will ~receive a fifth "Custom" medal~ not receive
the medal for that difficulty. Team games **do not** count towards the
medal achievement.
Completion of a medal will fill in the full correct color, as defined in
our `variables.css`:

Completion medals can be toggled on or off (hidden by default) with the
toggle button at the top of the section:

Didier map for the big french youtuber Fuze which already published
several OpenFront videos.
I took the real france, cut away the bordering countries and made it
look like Didier 😄
Gave it eyes, hands and feet.
Made sure we have some rivers, also put Corsica in the right bottom
corner!
It's quite large. Similar to the europe map. Has 42 nations (38 french
cities and 4 funny custom nations for the youtuber).
Made with [TsProphets map
generator](https://github.com/TsProphet94/OpenFrontMapGenerator), QGIS
and GIMP.
For public games I put a rare map frequenzy of 2 because most people
probably don't know Fuze.
@ibnhalwa from discord gave some insider knowledge about Fuze (He's
french, I'm not).

## Description:
### Refactor
- Moved `findBestNukeTarget()` (and child methods) from
`AiAttackBehavior` to `NationNukeBehavior` because it makes more sense.
- `NationNukeBehavior`: Renamed `mg` to `game` (So its similar to the
other nation .ts files)
- Moved the `removeOldNukeEvents()` method a bit
### New features
- Impossible difficulty nations are now optimized for SAM outranging!
- 1 of 3 nations is now a hydro-nation. They cannot send atom bombs.
They save up for hydros. This is to reduce atom-bomb-spam on the map.
- On impossible difficulty, the crown nukes the second place now (in
FFAs)
- On hard and impossible difficulty, nations now ignore the perceived
cost for nukes if they get heavily attacked. Reasoning: They should stop
saving for MIRV, they should defend with all their gold!
- On medium, hard and impossible difficulty, nations no longer throw
nukes at places where another team member already has a nuke "in the
flying process"
- Optimized `lastNukeSent` a bit (to respect nuke radius)
- Adjusted `maybeSendNuke()` to use 30 instead of 10 randomTiles on
impossible difficulty to improve chances of finding a perfect SAM
outranging spot
- On impossible difficulty, nations now ignore their "most hated enemy"
if the crown has 50%+ of the map (Very big danger). Instead they are
nuking the crown.
- Added `isFriendly` check to `findStrongestTeamTarget()`

Changes:
- Added a `Player::canAttackPlayer(other)` function to determine whether
a player can be attacked.
- This function is now used in most places where a fight can occur:
- AttackExecution (land attacks)
- Naval invasion
- Warship fight
- Nukes can't be thrown during the truce
- Immunity only affect human players. Nations and bot will fight as
usual, and can be fought against.
- The immunity timer uses minutes in the modal window.
UI:
- The immunity phase is displayed with a timer bar at the top. This is
from the original PR, to be discussed if it's not deemed visible enough:

## Description:
Trains are made of a primary unit (`TrainExecution.train`) followed by 6
cars (`TrainExecution.cars`). Currently when any of the units is
destroyed, a message "Your Train was destroyed" is shown. In worst case
scenario, when all cars are blasted by a nuke, 7 messages are displayed
to the user, but the train continues.
Since the actual logic is unaffected as long as the primary unit stays
alive, displaying messages is confusing. This PR fixes it. The message
is only displayed when the primary unit is destroyed. The following cars
are only there for fancy visuals.
## Screencast
##### Current - multiple messages for single train
https://github.com/user-attachments/assets/3df04c71-d899-4f68-af83-36c9d0ffa730
First nuke was a test.
Second nuke destroyed the entire train, prompting 7 messages.
Third nuke destroyed one full train and then some. Prompting many too
many messages.
##### Fixed - one message, only if train was fully destroyed
https://github.com/user-attachments/assets/1f3840a7-6c62-487d-af3a-82de39dad9e8
First train was only partially destroyed, no message was shown, delivery
mission completed A+.
Following 2 trains had the front engine destroyed and therefore were
promptly decommissioned.

A new map where you basically have to hop from island to island :)
We don't have such a map at the moment.
There is a special center island which isn't necessary to get 80% of the
map.
This map could be very interesting in team games. One hydro will destroy
an entire island.

## Description:
`MIRVExecution.separate` is consuming more resources than it needs to.
This PR introduces a series of minor performance changes which do not
alter the behavior of the selection algorithm. Assessing the code
initially, I was convinced there are multiple easy wins - starting with
the proximity check. However, after many hours of mostly math, no
alternative solution came close to the speed of current implementation.
Therefore this PR consists of only a few minor tweaks:
#### Removed `console.log`
This is by far the worst offender, in my test removing the three lines
of console log improved execution time from ~30ms down to ~10ms. The
logs are not very useful. I do not see a clear pattern in the logs
produced by the application therefore they were completely removed for
now. If there is a need for the log in production build, I suggest
adding single line with the number of destinations selected.
```diff
- console.log(`dsts: ${dsts.length}`);
- console.log(`got ${dsts.length} dsts!!`);
- console.log("couldn't find place, giving up");
```
#### Replaced multiple calls to `random.nextInt` with single call to
`random.next`
The flamechart shows calling pseudo random number generator is
expensive. Therefore instead of calling it twice, the code now generates
a single random number and derives further calculations from it. It
remains 100% deterministic and there should not be any noticeable change
to the enthrophy. This saves about ~1.5ms in my tests.
```diff
- const x = this.random.nextInt(
- this.mg.x(ref) - this.mirvRange,
- this.mg.x(ref) + this.mirvRange,
- );
- const y = this.random.nextInt(
- this.mg.y(ref) - this.mirvRange,
- this.mg.y(ref) + this.mirvRange,
- );
+ const r1 = this.random.next();
+ const r2 = (r1 * 15485863) % 1;
+ const x = Math.round(r1 * this.range * 2 - this.range + this.baseX);
+ const y = Math.round(r2 * this.range * 2 - this.range + this.baseY);
```
#### Caching of destination coordinates
Since the target tile coordinates are used a lot, instead of retrieving
them every time with `this.mg.x` and `this.mg.y`, they get cached as
`baseX` and `baseY`. To reduce usage further, I also exposed `x` and `y`
to `isOverlapping` / `proximityCheck` directly instead of passing the
tile. Since available methods operate on `TileRef`, this change requires
the calculations - manhattan and euclidean distance - to be inlined. I
do not think this is a big issue, considering this code is responsible
for very specific task. This saves another ~1.5ms in my tests.
```diff
- if (this.mg.euclideanDistSquared(tile, ref) > mirvRange2) {
+ if ((x - this.baseX) ** 2 + (y - this.baseY) ** 2 > this.rangeSquared) {
```

Fixes#2758
## Description:
This PR migrates lobby configuration updates from the HTTP PUT
`/game/:id` endpoint to a WebSocket-based intent flow.
The lobby creator is already authenticated via the game WebSocket, so
updating configuration through intents removes redundant authentication
and aligns with existing real-time lobby actions such as `kick_player`
and `toggle_pause`.
## Changes Made
- Added `update_game_config` WebSocket intent schema
- Wired client → transport → server intent handling
- Refactored `putGameConfig()` to emit WebSocket intent instead of HTTP
fetch
- Preserved all existing validation, partial-update semantics, and
client-side debouncing
- Left the REST endpoint untouched for backward compatibility
## Testing
- All existing automated tests pass
- Manual verification completed:
- Lobby creator can update all lobby settings
- Non-creators are rejected
- Updates are rejected after game start
- Bots slider debounce (300ms) remains intact
- No `PUT /api/game/:id` requests are made from the lobby UI
## Checklist:
- [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

## Description:
On the world map, if two teams of nations are fighting each other (left
side vs. right side), there is a possibility that an extreme warship
battle involving nearly 200 warships could occur. This PR helps resolve
that edge-case issue a bit.

## Description:
WIth my other new PR "Nations send much better nukes now (Part 1)"
nations got smarter.
Because of that, and based on player feedback, my own tests and youtube
videos (pros like enzo can't beat impossible difficulty nations without
warship infestations) we need to turn down the cheating.
With this PR, I reduced the cheating by 50% (again).

This is a very important PR for HumansVsNations (But also for
singleplayer).
Humans will throw lots of nukes onto nations, but nations didn't do
that. Until now :)
## Refactor
- Moved all the nuking logic to the new file `NationNukeBehavior.ts`
- Moved `randTerritoryTileArray()` and `randTerritoryTile()` to the new
file `NationUtils.ts` because we need that method in multiple places now
- Because we already have an `NationUtils.ts` (It contains the method
`createNationsForGame` for HumansVsNations) I renamed the old one to
`NationCreation.ts` to avoid confusion
## Bug fixed
- `allRelationsSorted()` in `PlayerImpl` returned dead players all the
time... Which caused nations to not attack / send nukes in some cases...
## Nuke-sending features / improvements
- On hard and impossible difficulty, nations no longer make sure that
nukes will only hit inside of their targets border. This logic very
often stopped nations from throwing nukes. Now their nukes are allowed
to hit TerraNullius (=> ocean!). And in team games, it's even allowed
that their nukes hit other non-friendly players as well! This is very
important for HumansVsNations.
- The basic check for SAMs now gets skipped if we are on easy difficulty
(easy nations are not smart enough to do that)
- I improved the basic check for SAMs (medium difficulty) a bit (nations
send less nukes into SAMs)
- On hard and impossible difficulty, we now use the new method
`isTrajectoryInterceptableBySam()` to avoid SAMs completely. It's
mirroring `NukeTrajectoryPreviewLayer.ts` logic a bit.
- I added "perceived cost" to simulate nations saving up for a MIRV
(Otherwise most hard/impossible nations will spend all their gold on
nukes). But if we are in a team game (MIRVs are not relevant) or if we
already saved up for a MIRV, the "perceived cost" gets ignored.
- Updated the "most hated player" selection in `findBestNukeTarget()` to
ignore very weak players. We don't need to throw nukes at players which
we can easily steamroll by land.
- Added `findFFACrownTarget()` to nuke the crown (based on difficulty).
- Added `findStrongestTeamTarget()` to nuke the strongest team.
- Updated `randTerritoryTile()` so that it has a higher chance of
returning the tiles of a
"leftover-nuked-to-death-player-with-some-tiles-left": `if
(p.numTilesOwned() <= 100) {return
random.randElement(Array.from(p.tiles()));}`.
- Changed `const range = nukeType === UnitType.HydrogenBomb ? 60 : 15`
to `config().nukeMagnitudes(nukeType).inner`. Should make more sense.
- Adjusted `nukeTileScore()` to search for units in
`this.mg.config().nukeMagnitudes(nukeType).inner` instead of fixed 25
- Adjusted `nukeTileScore()` to account for unit levels (levels got
ignored previously). Also increased score for ports from 10_000 to
15_000.
- I made sure that nations can nuke EVERY SINGLE TILE from an enemy,
even if the enemy has no structures ("Prefer tiles that are closer to a
silo" can no longer make the `nukeTileScore()` drop too much,
`bestValue` in `maybeSendNuke()` starts at -1 now)
- In the entire nuking logic, factories were missing. Now they are
added.
## Media
Nation team vs. nation team: They are nuking the very last pixels of
red, just like humans would do it 😀

## Description:
Introduces the Strait of Hormuz section in the Persian Gulf as a map!
This map is actually crazy fun to play on because of how the water
narrows to a small strait where control is necessary otherwise enemies
can transport boat to you easily. I figured a strategic map based on
modern-ish day conflicts would fit the theme, but man it's a great map
to play on.
