Add `Game.markUnitPlanDriven()` so executions can suppress per-step Unit updates
before the first motion plan is recorded.
Use it in TradeShipExecution to drop the spawn-time placeholder motion plan, and
align TransportShipExecution re-plan `startTick` with `ticksPerMove`.

## Description:
New version of the #2789 PR that is cleaner after changes made to old
pathfinding logic.
Adds logic to troop transport retreat behaviour which retreats a
transport to the closest owned tile instead of the source. Now if no
shores are detected (you lost all your shoreline while the transport was
out) we handle the return case same as if the original source was no
longer your territory.

## Description:
### Short path for multi-source HPA*
Math was not mathing, increased the bounds to 260x260, it is a bit
slower but should work better. The short path was breaking when player
owned a lot of shores. This is because the bounding box of tiles with
less than 120 distance + 10 padding could be as big as 260x260 and the
optimized array was set to 140x140. I made mistake of calculating it as
`2 * (60 + 10)` instead of `2 * (120 + 10)`.
### LoS path refinement
Previously, we ran 2 passes of LoS smoothing on the path. However, since
we are effectively tracing the same path, the line of sight is
essentially the same. This PR makes second line of sight stop on water
tiles with magnitude `n + 1` compared to first path. Practically, this
means it'll attempt LoS exactly 1 tile after previous corner. See
screenshot.

### SendBoatAttackIntentEvent
The flow of sending transport ships is currently strange. This PR makes
the flow more sane.
**Old flow**
```
- Player clicks TARGET tile, it can be deep inland
- Client asks Worker for the best START tile to TARGET tile
- Worker answers `false`, since the tile is inland
- Client sends BoatAttackIntent with START=false and TARGET tiles set
- Worker accepts BoatAttackIntent, computes DESTINATION as closest shore to TARGET
- Worker re-computes best START to DESTINATION
- Worker sends boat from START to DESTINATION
```
**New flow**
```
- Player clicks TARGET tile, it can be deep inland
- Client sends BoatAttackIntent with TARGET
- Worker accepts BoatAttackIntent, computes DESTINATION as closest shore to TARGET
- Worker computes START as the best tile to DESTINATION
- Worker sends boat from START to DESTINATION
```

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**.

## Description:
Issue discovered by @DevelopingTom, posted on Discord. After merging
pathfinding PR, transport ships lost the ability to navigate between
land tiles. For now, the quick fix is to select adjacent water tile and
select it for pathing. Conquer logic still applies to original
destination on the shore.

## 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:

## 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.
## PREPROCESSING
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

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

Description:
There is a boating exploit where players could repeatedly send and
retreat boats to effectively increase troop regeneration and maintain
almost double the max troop cap. This PR fixes#2388.
Summary
This pr adds a troop penalty to the boat retreats in
src/core/execution/TransportShipExecution.ts of 25 percent (currently
the same as land attacks, but may require fine tuning). this prevents,
to some degree, the ability to stockpile large amounts of troops above
your max cap.
Testing
I tested the change locally and confirmed that the troop penalty is
applied at the correct times and under the correct conditions, i.e. it
is only applied on successful retreat (applying on reteat initiation may
be confusing if you are told you have lost troops if the transport ship
never arrives anyway). The boating exploit is far less effective with
this fix in place.
Notes
- This is a exploit and does not introduce any new features.
- Existing game behavior outside the retreat penalty remains unchanged.
- The attack message is the same as the land attack, so the translation
should already be present.

not getting returned to owner. And small comment updates. And a const
for boatOwner to re-use.
The added bugfix is check for this.sourceTile === null in the retreat()
function in AttackExecution. A boat attack always sets removeTroops to
false because the troops were already removed from owner troops when the
boat departed. They don't have to be removed again in AttackExecution
init, when the boat lands and the attack starts. But at the end of the
attack, in retreat() in AttackExecution, the starting/boat troops still
need to be returned to the owner. That's why even if removeTroops is
false, when sourceTile is not null (only when it's a boat attack) we add
back the troops to the owner.

## Description:
Have AFK player's Warships not attack team members ships, like Transport
Ships boating in. If team mate conquers the AFK player, transfer over
Warships and Transport Ships to conqueror. The transfered Transport
ships attack in the name of the new owner when landing, and when they
are retreated they move back to a new owner shore tile if they have any.
Added tests. Expectation is this PR will be merged in v26 as the real
solution for the temporary workaround of deleting warships.
**Currently:**
- An AFK player can be attacked without troop loss by their team
members. For this purpose, isFriendly now returns false if the other
player isDisconnected
- But that meant Warships would get False from isFriendly too, and
attack the ships and boats of their team members.
- [Temporary workaround was to delete
warships](https://github.com/openfrontio/OpenFrontIO/commit/eea8db7a06aed50c005db35ad55ece026f7a3643)
as soon as the player was deemed AFK. But this is a disadvantage to the
team. For example the AFK player could have 6 warships in the waters,
either defending team land or helping the team cross over to the enemy
team.
- Transport Ships that were on the way to attack, were still deleted
after the AFK player was conquered. But this is also a disadvantage, if
say a transport ship has just managed to breach through to the enemy
lands despite warships all around. That could have made the win for the
team.
(Left to think about: do we want to transfer part of the defender troops
to the isOnSameTeam attacker? Defender looses less troops in the attack
from their team mate. You'd expect troops to lay down their arms mostly,
if the attacker is on the same team and doesn't loose troops themselves.
Those troops that they loose less than normal, are then added to the
attacker once they've been deemed conqueror. The enemy team can still
attack and do normal damage, and can still also be the conqueror so the
team members have to be fast.)
**Changes in this PR:**
- GameImpl > conquerPlayer: Transfer ownership of the warships to the
conquerer of their lands. If the conqueror is not a team member (other
team can still attack, in their case with troop loss), they won't get
the warships and the ships will be deleted like normal. If the conqueror
is a team member, have them capture the warships.
(Captures need to happen in conquerPlayer since this is right before the
last tiles are conquered and PlayerExecution finds out the player is
dead and deletes its units. Captures will be recorded in the stats just
like normal. Things like this add an extra incentive to be the fastest
to conquer the AFK player, next to getting their gold which is also
recorded in stats. The normal Event Box messages are also displayed.)
- GameImpl > conquerPlayer: Also transfer Transport Ships. As a note:
the limit of 3 transport ships concurrently out on water for one player,
can be exceeded in this specific case (the boatMaxNumber is only checked
for canBuild via TransportShipUtils, and in the init of a
TransportShipExecution, not for an existing TransportShipExecution with
a changing owner). This keeps the situation even for the team in terms
of ships that are already out to attack, which is fair.
captureUnit/setOwner won't do the full job here though, so changes in
TransportShipExecution are needed.
- TransportShipExecution: Added originalOwner. So we can check within
the execution itself if the Original owner disconnected, and if so if
the new owner is on the same team. Only in that case change private
this.attacker. This.attacker can still not be changed from the outside
in this way. Find new src of new owner to retreat boat to if needed, and
if new owner has no shore set it to null so the boat will be deleted
upon retreat. To find new src tile of new owner, use
bestTransportShipSpawn instead of canBuild because canBuild checks for
max boats = 3 etcera but the boat is already on its way so those checks
don't apply (we could get false back from canBuild because there's 3
ships out, while we only need to find the source tile so use
bestTransportShipSpawn).
- TransportShipUtils: to use bestTransportShipSpawn to find new owner
source tile to retreat to, we need to make sure it can handle a new
owner without shore tiles. When the new owner has no shore tiles
(candidates.length === 0), return false. This way it won't go on to call
MiniAStar which would have SerialAStar error on an empty this.sources
array.
- WarshipExecution: Changed isFriendly. This makes sure we have the
wanted behavior: allied/team ships should not attack each other once one
of their owners goes AFK.
- AttackExecution: added one more test specifically to check if attack
on AFK teammate is still witthout troop loss "Player can attack
disconnected team mate without troop loss". Also a bugfix that I left in
after removing a related change from this PR: Add a check for
removeTroops === false in the retreat() function, so at the end of the
attack we don't add troops back to owner troops if they were never
removed in the init. This check in retreat() is actually a bug fix
because removeTroops is in the constructor and can be set to True, but
in retreat() troops would then have been given back after not being
removed at init.
- DefaultConfig: small addition to comment.
- Disconnected.test.ts: added tests. Added useRealAttackLogic because at
least "Player can attack disconnected team mate without troop loss"
needs to use the real attackLogic.
- TestConfig: new class useRealAttackLogic extends TestConfig class, so
a test setup can use the real attackLogic from DefaultConfig instead of
the mock function in TestConfig.
- Setup.ts: for the test setup, add parameter to accept
useRealAttackLogic extension class. Defaults to TestConfig.

## Description:
Add a rail network to handle train stations/railroad between structures.
Changes:
- `RailNetwork` is responsible for the train station graph. Use it to
connect new `TrainStations`
- A `RailRoad` connects two `TrainStation`
- No loop possible in the rail network
- Train stations handles its railroads
- Added a layer to draw the railroads under the structures
#### Clusters
- To speed up computations, each `TrainStation` references its own
cluster
- A cluster is a list of `TrainStation` connected with each other,
created by the `RailNetwork` when connecting the station
- Train stations spawn trains randomly depending on its current cluster
size
- A `TrainStation` decides randomly of the train destination by picking
one from the cluster
#### Production building:
- Added a factory which has no gameplay impact currently. _To be
discussed._
#### Train stops:
- When a train reaches a factory, it's filled with a "cargo". The loaded
trains has no impact currently. _To be discussed._
- When a train reaches a city, the player earn 10k gold
- When a train reaches a port, it sends a new tradeship if possible
- If a destination/source is destroyed, the train & railroad are deleted
too

## Description:
Improve type safety and runtime correctness by:
1. Enabling TypeScript's
[strictNullChecks](https://www.typescriptlang.org/tsconfig/#strictNullChecks)
compiler option.
2. Replacing all loose equality operators (`==` and `!=`) with strict
equality operators (`===` and `!==`).
3. Cleaning up of type declarations, null handling logic, and equality
expressions throughout the project.
Currently, the code allows implicit assumptions that `null` and
`undefined` are interchangeable, and relies on type-coercing equality
checks that can introduce subtle bugs. These practices make it difficult
to reason about when values may be absent and hinder the effectiveness
of static analysis.
Migrating to strict null checks and enforcing strict equality
comparisons will clarify intent, reduce bugs, and make the codebase
safer and easier to maintain.
