Do you guys remember that magical map from that Harry Potter movie? That thingy a couple of guys at Dropbox made during their hackathon? We took it to the next level...

This is a little toy project of mine that lets you simulate digital logic graphs. It was inspired by Minecraft's Redstone and the Piet esolang. It's got some serious drawbacks-- you write circuits as PNGs and simulate them with a Python interface. It's slow to run and slow to experiment with. And it is certainly difficult to use for people with any kind of color blindness. But despite that, I hope this can still be a fun toy!

Hey everyone! Long time lurker, first time poster. I've just reached beta in my game BoxByte Lyte. -What is it- It's a free 3d arcade game for hardcore players that uses color matching in interesting ways. Also it's a one button game, well movement and one button. Cool huh? The final release will be free too. -What I need- This is a very challenging game, so I really need to balance the difficulty so that it's still hard but not impossible. It would be great just to hear your experiences of the game and how far in it you got. -Where can I report bugs?-…

This was more of a sandbox to play with Raphael and Flot than anything else but I think there are some interesting statistics in there. It'd be awesome to do this over time but I really don't have the spare time required.

Hello HN. This is a project me and some friends built at university in 2017. It was originally built in a rush, but we've added a few improvements over the years. It's a fun game to host at a demoparty and project on a big screen - We did that at Instanssi many times. The implementation is still rough, and suffers from the fast pace of the modern web - The frontend is likely very outdated, and the backend is built with Vapor 2 and Swift 3.1, both no longer supported. You can host this yourself, but it might be a bit of a pain to set up. The WebSocket protocol is fairly trivial to work out…

This weekend I participated in my first hackathon at TechCrunch Disrupt, and built an HTML5 game with a few people that I met at the event. We got honorable mention, putting us in the top 6 teams of 104 competing. I'm looking for some feedback on the game, so here it is: http://venturecrapital.us Source: https://github.com/wylieconlon/Venture-Crapital https://github.com/dmitric/venturecrapital-server

Happy Halloween! Instead of going to a Halloween party this year, my wife and I decided to run a tiny Hackathon and built this little retro choose-your-own-adventure to pay tribute to a popular series of yesteryear. Try and escape! Also pumpkin mode!! We made liberal use of ChatGPT for code, DALLE3/Midjourney for images, but did most of the storyboarding/writing ourselves because we couldn't stand the style of GPT4/Claude.

Site: http://localhackathons.com/ (currently bay area only) Done very raw, super basic MVP. Would love your feedback whether this is useful or not to some and if you'd find a further developed version would be of good use. Thanks

Hi Hacker News! My friend and I [1] would like to share with you something we did this week-end. We really like the idea of game jams like the Ludum Dare, and we’d like to participate, but it’s often complicated for us, as we are often limited by the rules inherent to this kind of competition: we have to be available at specific dates, and the rules doesn’t always work for us. For example: if you want to participate as a team in a Ludum Dare compo, you have 72h instead of 48h, and you are not required to publish your code. We realized that what we really like is: - To work together. - The…

I went to the ADVANCE Hackathon in Cologne, Germany last weekend and this is a project I created together with @snnd and @newmetl. We used node.js and socket.io in the backend and HTML5 + JS in the frontend. The rules are simple: Make your and your teammates' gaming pieces fit into the highlighted area without talking to your mates. The levels are generated randomly, so they might be too easy or too hard from time to time. I'd like to emphasize that this game has been created within less than 24 hours! http://fititgame.com/ http://hackathon.advance-conference.com/ Feedback and criticism are…

Im working on a mind mapping app that would allow for integration of gamification features and be nicer and easier to remember. I was missing more advanced graphics from apps and being able to treat it as my note taking and learning tool. i.e. how (and why?) should I remember a mind map if it looks the same like all other maps and all i can do is pick couple of shapes and dashed/dotted lines? this simply doesnt work with my brain so i decided to create something better :) map on page is a preview of this, but im curious about the quiz, typing games and cheatsheet, would love some…

A minimal "@ moving around a hardcoded map" implemented in a bunch of languages, some by me and some contributed by others. A slightly more interesting riff on the Hello World or 99 Bottles of Beer theme. More languages or improvements on existing ones would be nice :) There's a github repo at: https://github.com/nrkn/SimpleRL

Hello everyone! I've finally finished my latest side project - a RPG game made in Blazor. It started as a small project to learn some Blazor (I'm .NET dev but kept mainly to backend and ASP.NET). I had such a good time coding it that at some point I decided to make a full featured game out of it. I might've have bitten off more that I could chew as RPGs have so many systems and elements but overall I think it worked out well, especially for a single person project. I want to hop on the next project soon so any comments/questions/tips than can make me better really appreciated!

Hey gang, My names Ryan. I Develop Desktop applications, usually for Windows. I made this little Trainer application , if anyone wants to try it out. It lets you manipulate values in memory, in-order to hack stats, crafting materials, etc. If you like it, have any suggestions, or angrily yell about the console release, feel free to hmu. https://github.com/howzitkiffen/Cyber-Punk-Trainer (PS: Looking for work!)

I made this as a pair programming exercise with o1-preview. o1 did most of the heavy lifting, through high level prompts, but eventually I needed to diverge from it to get to completion. My initial prompt was: --- I'm making a web app: It's like 4chan, but each thread starts with a gps coordinate. People can only post text and images. I want to build it with flask and sqlalchemy. I want just the backend and data model that supports these threads, anonymous users, and users that can register a permanent username. Write as much of it as you can for me. --- This produced a fully scaffolded…

I'm working on the Survival Crafting RPG that you would have played on your Apple II back in the '80s. You can think of it as Valheim's gameplay crammed into the tile-based UI of the old Ultima games. It has a procedurally-generated open world with towns and NPCs to talk to, all the resource gathering, mining, crafting stuff you'd expect in a modern survival game, and some good old fashioned dungeon crawling to boot. I've been working on it off and on for the last several months. It's complete up through the Bronze Age (in Valheim terms). Let me know what you think!…

Ryd.io As a capstone project for Galvanize's data science immersive I took another look at the NYC Taxi data set. A ton of analysis has been done on individual rides/cars and I was curious about what story would be told by looking at this data through the aggregate. Through the clustered map you can identify different 'personalities' of the city with a birds eye view. Check it out here http://ryd.io/cluster_map I've just spent past couple weeks working hard on this project and would love to talk to anyone about it if they are interested. After the conclusion of the…

Hey everyone, I'm Fabio, a very long time lurker here. Today I want to celebrate and share with you, again, a game that I conceived more than 8 years ago. I shared it last week with all its history (if you're curious) [1], but it just stayed in the "shownew" and never reached the main "show" page, hopefully this time it'll do better (:crossed_fingers:)! What changed since last week? Today I've also published the mobile apps for both iOS and Android (last week it was just web), which are also my first mobile apps ever. So I believe it's still a worthwhile post and something to show :) I'd…

Hi HN, I want to share this short documentary on a 183 person hackathon that I (age 17) ran with my friends this summer. Coding changed my life. However, I've always struggled to find a space with folks my age who also find joy in coding, especially since the pandemic begun. My friends & I wanted to run an amazing in-person hackathon as soon as it was safe to do so, and Assemble was that event. To try and help other teenagers organise their own hackathons, we’ve open sourced all of our planning documents - including finances, marketing emails, website code, run-of-show, etc - at…

Hey yall, I built this for my makerspace. We wanted to let each other borrow things, but also didn't want to put up a big shiny sign saying "hey everyone, my garage has a super fancy oscilloscope just sitting there" and also didn't want to necessarily always need to say yes to everything. However, when I show it to people, they've been suggesting using it for other things like board games, or wedding equipment, etc. I'm still trying to find PMF, so please let me know what you think! For the stack, it's all Elixir + LiveView which is really nice, and then Fly.io, Fly's MPG, Tigris Data,…

Hey, I've shared this game while it was still a work in progress in one of the Tell HN threads. I was pleasantly surprised that a lot of people tried it, and I got some positive feedback and constructive criticism. Anyway, I found a gamedev library I really like - Kaplay [1]. What I like about it is that easy things are easy. Meaning I could have fun building the game without learning (or fighting) a new tool. I always wanted to make games, but this is the first one I actually did. And I have to tell you - game development sparks joy! It combines so many things (game design, programming,…
