WasmBots – A WebAssembly-powered programming game

I've been working on a browser-based programming game where you write bots to explore procedurally generated dungeons in any WebAssembly-compatible language. It's like a minimalist roguelike where your character's brain is a program you write. There are pre-made libraries for C, Rust, Zig, Go, and AssemblyScript. The game mechanics are intentionally simple for now, but the challenge comes from building up your bot's understanding of the world from limited local information. Your code needs to handle mapping, pathfinding, and strategy while dealing with monsters and potentially hostile other…

    I made a web game called Almost Pong2022 · lessmilk.com · ▲1,135

    Hi HN! I made many small web games in the past with Unity or Phaser. But this time I wanted to make something completely on my own. So I coded a basic game framework in plain JavaScript, and used it to make Almost Pong. This was a really fun project that taught me a lot about JavaScript, and I plan to make more minimalist games with this framework. Interesting fact: Almost Pong doesn't load any assets, all sprites and sounds are generated with code. Happy to answer questions, and please let me know if you have any feedback on the game. Thanks!

    I'm writing an MMORPG game for learning programming2022 · bytelegend.com · ▲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://bytelegend.com/ 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…

  • Maginet, a cross-platform strategy game with Rust/WebAssembly2023 · evrim.zone · ▲8

    I hereby present my little tiny pet project that entertained me for the past six months. In this post, I briefly present Maginet and its technical components. It is a turn-based strategy game that is built using Rust and compiles to WebAssembly with HTML5 bindings, which works on mobile and desktop alike! It comes with many game mechanics and components, including an AI opponent and online cross-platform multiplayer. There is so much to discuss even for a project of a smaller scale, but I am nevertheless excited to share a little bit about how you can actually build a game in Rust,…

    About a month ago, I shared the Day 1 prototype of this project (https://news.ycombinator.com/item?id=46448670). It has since evolved into a somewhat more polished "Slot-Machine Deckbuilder." I also recently moved the project from qq-pwn.com to alt-qq.com. I did this mid-development specifically to see if I could migrate a live player base and session states without losing people. The Design Challenge: The core of the game is a "One-Armed Bandit" dungeon crawler. The challenge is balancing the "house always wins" nature of slots with the player agency required for a good…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    I realized that the PDF engines of modern desktop browsers (PDFium and PDF.js) support JavaScript with enough I/O primitives to make a basic game like Tetris. It was a bit tricky to find a union of features that work in both engines, but in the end it turns out that showing/hiding annotation "fields" works well to make monochrome pixels, and keyboard input can be achieved by typing in a text input box. All in all it's quite janky but a nice reminder of how general purpose PDF scripting can be. The linked PDF is all ASCII so you can just open it in a text editor, or have a look at…

    I originally built this app to organize and reuse interesting React + Tailwind components I came across on Twitter, inspired by the shadcn/ui approach. Later, a friend started contributing their own components, and it got me thinking—this could grow into something bigger, like an NPM for design engineers to share and use components. Would love to hear your thoughts!
