Dynamic OSM World Domination Match

Backend match for a real-time OpenStreetMap world-domination strategy game.

Current Slice

• .NET 10 clean architecture solution
• Pure domain rules for territory stats, movement ETA, combat, map control, and victory
• Deterministic Cardiff match match service
• Minimal API endpoint at /api/matches/cardiff
• Custom lobby flow with server-owned join, start-position selection, start-game state, player display names, and ended games
• API-authoritative snapshot model for map state and leaderboard data
• xUnit coverage for domain, application, and API behavior

Run Tests

dotnet test Game.sln

Run API

dotnet run --project src/Game.Api/Game.Api.csproj --urls http://localhost:5057

Then open:

http://localhost:5057/api/matches/cardiff

Run UI

The API serves the working lobby-first UI from src/Game.Api/wwwroot.

dotnet run --project src/Game.Api/Game.Api.csproj --urls http://localhost:5057

Then open the available games list:

http://localhost:5057/games

Current lobby behavior:

• players choose a display name before joining a custom game
• custom games stay visible in the lobby after they are ended
• the API owns lobby state, faction names, territory ownership, and leaderboard values
• realtime multiplayer synchronization should come from the API layer over SignalR; HTTP snapshot fetches are for initial load and recovery
• territory attacks, reinforcements, and start claims broadcast Tactical Pulse presentation events so connected players see the same takeover animation metadata
• in-game options let players enable/disable Tactical Pulse animations and generated sound cues independently

src/Game.Web contains the planned Vite/React package boundary for the next frontend iteration. This environment currently has node.exe but no npm, so the checked-in working UI is dependency-free static browser code served by ASP.NET Core.
