   Show HN: Boardzilla, a framework for making web-based board games Tldr: We’ve made a framework for web-based board games. You can try out some games over at https://boardzilla.io, or you can take a look at https://docs.boardzilla.io to learn more about how to develop your own game. Source is available at https://github.com/boardzilla Hey y’all. My brother and I have made a framework for board games. During the pandemic we started to look at BGA but got discouraged by how old-fashioned the tools were and how cumbersome the development process was. We set out…

   SineRider - A game about love, math, and graphing built by teenagers▲220

   Hello everyone! It was so fun working on this project for the past few months with some of my fellow high school students :) I am so excited to share our first prototype and hopefully we'll be done with it all soon! <3 (ofc, it's open source, contribute here: https:&#x2F;&#x2F;github.com&#x2F;hackclub&#x2F;sinerider) The goal of the game is to slowly teach function composition that get progressively more complex while you also help the ghosts ski on the slopes and explore the entire map!

   I made a browser-based RTS game▲212

   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&#x2F;Canvas and WebSockets. On the browser side the map is pre-rendered (as a background image), just the mobile units&#x2F;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…

   Meatshields – An in-browser turn-based strategy game▲113

   A few months ago (82 days to be exact!) I posted a link on HN to my game, Meatshields. A bunch of you commented and played my game and gave me some wonderful feedback. Over the last few months I've been playing with many of you and implementing the best of everybody's suggestions. So, thank you, HN for all your help! I feel this is an extreme overhaul I couldn't have done without your input. Since then, I have: Dramatically improved our hosting platform (So it HOPEFULLY won't go down this time (oops.)), Added two new units, Rebalanced all existing units, Added many more maps, Improved the…

    I'm writing an MMORPG game for learning programming▲229

    Hi, I've been developing an HTML5 MMORPG game where people can submit code to play a game, like collect items, destroy defense towers or kill monsters, etc.. I've been working on this for over 1.5 yrs (all my spare time) and now it's ready for preview, does anyone want to try it out? It's mostly opensource (and the rest will be opensource sooner or later) Please access it with PC, it's an HTML5 game: https:&#x2F;&#x2F;bytelegend.com&#x2F; I really want it to expand to more languages, but right now I've only finished Java part. I wonder if anyone can help me with other languages. Besides, I'm…

    ChatGPT-powered dystopia simulator▲195

    OP here. This comment contains SPOILERS so try the dystopia simulator first before reading further! I built "WeChatGPT+" in December on top of GPT-3. It was pretty surreal when OpenAI released an actual product named "ChatGPT Plus" a few months after that. Then the Microsoft partnership was announced, Bing AI was released, and marketing materials were leaked indicating that Bing AI would start including advertisements within the chat responses. Reality imitates fiction, I guess. Today - literally a few hours ago - OpenAI announced public ChatGPT API with 10% the cost of GPT-3. I immediately…

    I built a MCP server so Claude can play Minesweeper▲123

    Hi! I build an MCP server that allows clients to play Minesweeper. It turns out that Claude is not very good at it (makes obvious mistakes, hasn't won a single game on a 9x9 board after many attempts). I am curious how I can prompt Claude to do better?

    My platforming game written in C 89▲127

    I have been working on this game somewhat sparsely for the past three years or so. However, it is still in a very early stage, and there is a lot of work to do. One of my friends encouraged me to post about it here, since he felt people might find interesting how I don’t use any libraries for it. The game can be played on a browser by virtue of WebAssembly. There are native ports using either MiniFB or SDL2, but you have to build those yourself. I decided to write the game in C because I feel like it is a simple language that a lot of people can understand well enough, and I didn’t think I…

    Dear Hacker News, I'm kindly asking for your participation in the open beta for my AI-managed mini-games website. Thank you in advance! For a limited time window, I'm setting the all-free feature flag to true. I hope you have a lot of fun exploring the AI's sense for games! Here and there, I tweaked it to help with visual consistency. I would be deeply grateful if you opted into analytics. $2,300 in API tokens... Cheers!

    GitGuessr▲98

    I built this game as a playful way to train code reading skills. You're dropped into a random location in a real GitHub repo where some lines code are hidden. The goal is to pick up clues from the surrounding code and fill in the missing lines as quickly as possible. It currently has curated game content for Python, TypeScript, JavaScript (by most metrics the top 3 languages on GitHub). I had the idea when it dawned on me that reviewing and understanding code spat out by an LLM is a key skill for the AI era. (I sincerely hope you're critically reviewing what your favorite LLM is serving…

    I made an in-browser game called Meatshields (https:&#x2F;&#x2F;meatshields.com) which allows players to play a turn-based strategy game against many different players simultaneously. The game is heavily inspired by Advance Wars and I wanted to give people the multiplayer experience I loved from my childhood. I couldn't find an online version of the gameplay that I really loved (Advance Wars By Web (AWBW) is FANTASTIC, but there are actually a few gameplay mechanics in Advance Wars that I take issue with that I wanted to try to balance myself), so I decided to make my own. It's still pretty…

    This is a little puzzle game I made based on Wolfram's rule 30[0]. I was doing some sketches based on old Genuary[1] prompts and for some reason this idea stuck with me, so I polished it up into a hopefully playable state.
