    This is a simulator of a frigate from about 1800. It has realistic physics, tuned to match historical performance. The UI is based around commands given in period naval language. Rather than use the current weather, it has a full year's weather data (for 1980 - taken from https://psl.noaa.gov/data/gridded/data.ncep.reanalysis2.html). This allows the weather to change realistically under time acceleration. To learn the basics of handling a square-rigged ship, start the "Harbour" scenario, click on the instructions button at the bottom left, and follow the instructions…

    I've seen quite a few simming discussions on HN, so thought some of you might like this - I've created a map-centered, tactical submarine simulator and it's been a blast to make. I grew up playing Silent Service II on Atari ST with my dad, then got into Silent Hunter IV in the 2000s, and most recently have been loving the more recent UBoat. In each case, the part I always enjoy the most is the plotting and charting aspect - essentially beating uncertain estimates with geometry. So I decided to see how far I could get making my own sim that focused nearly entirely on that aspect. You listen…

    I've posted this game here before, hopefully a repost is fine as the game has changed quite a bit (improved AI, improved mapeditor, much quicker gameplay, etc). Game is based on JavaScript/Canvas and WebSockets. On the browser side the map is pre-rendered (as a background image), just the mobile units/buildings and animations are dynamically rendered. The lobby server is made in node.js, but the game server is C++ for performance reasons (mainly the pathfinding). I found the C++ WebSocket libraries out there to be too difficult to use so I made my own based on the rfc. Overall I…

    _Vector Defense_ is a retro vector graphics style tower defense game (demo). This was a holiday "weekend" project. I wanted to recreate some of the fun I had in the past with https://en.wikipedia.org/wiki/GeoDefense and one other (Android?) game that may predate GeoDefense, but which was fixed grid and placement. Creation Details I "wrote" this in English. 99% of my development came from carefully articulated directions and requests from me to Gemini 3 (usually planning mode, in Antigravity IDE). Music is also AI generated via Suno.com, from my prompts. SFX are samples…

    Hi HN, I've been building a browser-based multiplayer strategy game called Borderhold. Matches run on large maps designed for hundreds of players. Players expand territory, attack neighbors, and adapt as borders shift across the map. You can put buildings down, build ships, and launch nukes. The main thing I wanted to explore was scale: most strategy games are small matches, modest maps, or modest player counts, but here maps are large and game works well with hundreds of players. Matches are relatively short so you can jump in and see a full game play out. Curious what people think.…

    This is something that I've been working on on-and-off in my spare time for the last few years. I started in 2020 during Covid trying to do a Mount and Blade style map in UE4, and it grew from there until where it is now - I would just add a feature, then another, until it came together. Since the start of the year I've really been trying to polish it some more. I've got the full thing planned for a Q3 25 release.
