## Description: I hope we can get this into v30? The nation count is configurable now, just like the bot count. Replaced the "Disable Nations" toggle with a nations slider (0–400) in SinglePlayer and Host Lobby modals. <img width="710" height="121" alt="Screenshot 2026-03-03 021952" src="https://github.com/user-attachments/assets/c8d0f0c3-db51-4303-95fa-dbc770460ec2" /> Public games are staying exactly the same, this is just for singleplayer and private lobby fun. Youtubers could play HvN against 400 nations, for example. Singleplayer enjoyers no longer have to play against 1 nation in HvN, they can freely choose. `GameConfig.disableNations: boolean` got replaced by `nations: number (0-400, optional)` `undefined` = map default, `0` = disabled, number = custom count Nations slider defaults to the map's nation count, shows "(MAP DEFAULT)" label when unchanged Compact map toggle reduces nations to 25% when at default, restores when toggled off (just like we already do with bots) The nation count for HvN no longer automatically matches the human count in singleplayer and private games, only in public games. **What if there aren't enough nations configured for the map?** We just use the HvN logic (Generate random nations) ### Warning **This infra PR also needs to get merged: https://github.com/openfrontio/infra/pull/263 Otherwise players can set 0 nations and get achievements.** ## 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 - [X] I confirm I have thoroughly tested these changes and take full responsibility for any bugs introduced ## Please put your Discord username so you can be contacted if a bug or regression is found: FloPinguin
Pathfinding Tests

Benchmarking
Running a Single Scenario
# Run default scenario with default adapter (NavSat)
npx tsx tests/pathfinding/benchmark/run.ts
# Run specific scenario
npx tsx tests/pathfinding/benchmark/run.ts default
# Run with specific adapter
npx tsx tests/pathfinding/benchmark/run.ts default legacy
Running Synthetic Scenarios
Synthetic scenarios are auto-generated from maps with random port selections and routes.
# Run single synthetic scenario
npx tsx tests/pathfinding/benchmark/run.ts --synthetic iceland
# Run single synthetic scenario with specific adapter
npx tsx tests/pathfinding/benchmark/run.ts --synthetic iceland legacy
# Run ALL synthetic scenarios (comprehensive benchmark)
npx tsx tests/pathfinding/benchmark/run.ts --synthetic --all
# Run all with specific adapter
npx tsx tests/pathfinding/benchmark/run.ts --synthetic --all legacy
Benchmark Metrics
The benchmark measures three key metrics:
- Initialization Time - How long it takes to preprocess the map
- Path Distance - Total distance across all routes (quality metric)
- Pathfinding Time - How long it takes to compute paths (performance metric)

Generating Scenarios
Generate Synthetic Scenarios
Synthetic scenarios are generated by:
- Finding all water shoreline tiles on a map
- Randomly selecting 200 ports
- Creating 1000 routes connecting nearby ports
# Generate scenario for a single map
npx tsx tests/pathfinding/benchmark/generate.ts iceland
# Generate scenarios for all maps
npx tsx tests/pathfinding/benchmark/generate.ts --all
# Force overwrite existing scenarios
npx tsx tests/pathfinding/benchmark/generate.ts iceland --force
npx tsx tests/pathfinding/benchmark/generate.ts --all --force
Interactive Playground
The playground provides a web-based UI for visualizing pathfinding results, comparing algorithms, and debugging.
Starting the Playground
# Start with path caching enabled (default)
npx tsx tests/pathfinding/playground/server.ts
# Start without path caching (to measure uncached performance)
npx tsx tests/pathfinding/playground/server.ts --no-cache
Then open http://localhost:5555 in your browser.
