## Description:
Five performance improvements to the map generator, measured on three
maps of increasing size. End-to-end time on `world` improved ~15×, heap
allocations ~19×.
| Map | Before | After | Speedup |
|-----|--------|-------|---------|
| bosphorusstraits (~612K tiles) | 578ms / 594MB | 45ms / 134MB | 13× /
4.4× |
| world (~2M tiles) | 2333ms / 2128MB | 150ms / 553MB | 15× / 3.8× |
| giantworldmap (~8M tiles) | 10701ms / 9300MB | 635ms / 2509MB | 17× /
3.7× |
Changes (one commit each):
- **`--workers` flag**: bounds concurrent map processing to limit peak
memory
- **Flat `[]bool` visited sets**: replaced `map[string]bool` keyed by
`fmt.Sprintf` with flat `[]bool` indexed `x*height+y` — the dominant
cost
- **`neighborCoords` with stack buffer**: eliminates per-call slice
allocation for neighbour lookups
- **`Terrain` struct 24→16 bytes**: field reorder + `uint8` type for
`TerrainType`
- **Nil buffers early**: releases image/terrain arrays as soon as
they're no longer needed
- **BFS mark-visited on push**: each tile enters the queue once instead
of up to 4×, halving queue memory
also fixes a bug (according to Claude):
Here's the bug: createMiniMap downscales by averaging/sampling 2x2
blocks, copying field values across — including Ocean=true from the
parent scale. When a single connected ocean at 1x splits into multiple
disconnected bodies at 4x (because narrow water channels disappear when
you halve resolution), those smaller fragments still carry Ocean=true
from the carryover. The 4x processWater call picks the new largest
fragment and sets it to Ocean=true, but never clears the others — so
multiple disconnected bodies end up flagged as Ocean.
This PR's fix: before the new BFS pass, zero out every Ocean flag, so
only the truly-largest body at the current scale ends up marked.
It's incidental to the perf work but it's a real semantic change — the
on-disk .bin files will differ from main on any map where ocean splits
across downscaling. The PR doesn't mention it, which is why I flagged
it.

Change inspired by Territorial.io . Renames the Mediterranean sea map to
Mare Nostrum, the ancient name of the sea given by the Romans. The NPCs
of the map are already roman provinces, so this change is more thematic
and also adds a creative name like "Gateway to the Atlantic" and
"Between Two Seas"

This is probably the most heavy naval map we are gonna get. Given this

has a rotation of 3 , low but still should pop in for people who prefer

Re-adds and reworks the previously April Fools "Reglaciated Antarctica"
as a new map, this time with proper elevation data: Map of Antarctica

The "appeal" of this a map is that it has no green terrain. (As such it
has a really low rotation number (of 1). )
This also completes the Continental map category (antarctica was the
only continent out of the traditional 7 missing).

/>
Because of mixed opinions about replacing the maps, i propose at least
this temporary compromise: Bering Sea gets added as a new map and Bering
Strait gets its rotation lowered to a small number. Since the classic
maps are probably being taken off rotation, we should have some small
breathing space for the 2 maps.
In the near future we should discuss between mapmakers in the dev server
whether we keep, replace or completely take Bering Strait off rotation,
and/or a community poll.

This has been a heavily requested map in the community, having
suggestions in the Discord, Subreddit and even in some videos (for
example i saw Ultimus Rex suggest an aegean map when asked what maps he
would like in his last stream)
The map is designed so that the greek and turkish main landmasses are
around 400,000 pixels in area, which combined account for around less or
equal to 80% of the map. This means players will have to cross the sea
to win, and to do so they will have to hop across the islands, which
means there will be heavy warship action, instead of having stalemates
like in most island maps where the gap between islands is too large and
players would rather bomb each other.

So I thought why not make another one, this time a bit focused on
traders (tiny islands to trademaxx)
And two big islands (about 50% of the map land tiles). So its big
islands vs small islands.

This PR readds the Yenisei map, with it being about 3 times smaller than
before. I haven't updated the en.json file, as it still has the string
for the map, which was probably forgotten when the map got removed from
the repo.

- DEBUG - New output
- ALL - New output (includes the logs from when removal/performance is
enabled)
In addition
- Add `-verbose` (`-v`), `-log-level`, `-log-removal`, and
`-log-performance` flags to map generator
- No changes to default behavior of `go run .` without the new flags
- excludes test maps from performance warnings (test maps already skip
the removal steps)
- updates readme with the different flags and how they impact the logger
Default run (matches existing)
`go run . >> output.txt 2>&1`

## 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
## Benchmarks
### Compared with legacy in default - hand picked - scenario:
```
Initialization: 95.95ms -> 227.29ms
Pathfinding: 3038.43ms -> 6.45ms
Distance: 26972 -> 26810 tiles

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`.

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:
tldr: `npm run docs:map-generator`
Adds documentation to the `map-generator` go code.
This has no functional changes, other than the renaming of the package.
I used the github url, though this can be set to anything as long as it
contains a `.` so that the docs parse it correctly. Go doc best
practices seem a little verbose and terse, but attempted to comply
Future Facing (to get these docs viewable without running locally):
- Wait until the -http issue is sorted, then these are easy to
statically host alongside builds
- Could use the legacy `godoc`
- Could do formatting after outputting the `txt` output
## Change List:
- Add documentation to all types/fns in map-generator go code
- Ensure this outputs correctly with `go doc`
- Add `docs:map-generator` command to package.json. This runs `go doc`
in `map-generator` w/ appropriate flags to generate full documentation.
(see notes in readme)
- rename `map-generator` module to work around pkgsite assuming all
packages without a . are stdlib (this makes `-http` work at all)
- Add new sections to README and update existing sections
- Add additional references to locations in the primary code base where
things can be found
- Update documentation in the ts theme files to add output color
mappings - this ensures that everything needed to trace the input file
-> in game rendered asset is fully documented.

Resolves#2594
## Description:
- Added an optional `--maps` flag to the map-generator that allows
passing a subset of maps to process.
- Updated `README.md` w/ documentation for using the new flag
Used the [go/flag](https://pkg.go.dev/flag) package.
Running without the flag, or with no arguments matches existing behavior
of processing all the maps defined in `main.go`
`go run .`
`go run . --maps=`
New behavior is triggered to process a subset of maps by passing the
`--maps` flag. Multiple maps are defined in a comma-separated list
`go run . --maps=world,africa`
Or a single map (useful for map development)
`go run . --maps=fourislands`
If an invalid map is passed, the process aborts and renders the error
```bash
go run . --maps=invalidmapname
Error generating terrain maps: map "invalidmapname" is not defined
exit status 1
```
By using the default flag package, we get `--help` for free:
```bash
go run . --help
Usage of <path-to-exe>/exe/map-generator:
-maps string
optional comma-separated list of maps to process. ex: --maps=world,eastasia,big_plains
```
I do not write GO often. Gemini contributed to this syntax.

I'd like to submit some PRs in the future to add additional options for
logging and debugging to the map-generator, however I don't want to
introduce any code style changes in feature requests.
## Description:
I noticed there was not any style guide or formatting being done for the
go files, and went with the simplest built-in approach w/ [go
fmt](https://go.dev/blog/gofmt)
- Adds a `format:map-generator` npm command that will run the default
`go fmt` in the `map-generator` directory to format the go code.
- Runs the formatter and commits the changes to `main.go` and
`map_generator.go`
- Updates the `map-generator` README:
- Updated location for generated files
- Updated Links to use markdown links
- Add `info.json` example
- Add in-game enabling instructions with list of files to modify
- Add development tools section with format command
