This is a Reddit post about simulating two gears in a game. It's for game developers working on physics or mechanical systems. The post was shared on July 15, 2023, and discusses the technical implementation of gear… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Simulating two gears in my game launched in 2023; newer entries below may have overtaken it.

    I've seen some interests in (simulation) video games here on HN so I thought I'd share a short version of our story. More than 6 years ago, me and my friend from university were playing around with an idea of making a game we always wanted to play. We worked on it on weekends but the progress was quite slow, especially due to so many dead ends and wasted effort. Eventually however, we solidified our direction and decided to take the risk to resign from our well paid SWE jobs and work on it full time. It took more than a year but yesterday we have finally released it on Steam:…

    Modd.io is a collaborative game editor that runs in browser. It's kind of like Figma for game dev. We made this engine low-code and multiplayer-first, so developeres can quickly prototype casual multiplayer games. I hope some of you guys will find this useful. Would love to hear feedback also. Thank you. Engine Demo: https://www.modd.io

    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.

    Long time reader, first time self-promoter. I'm a bicycle mechanic that figured I could make the process of bicycle wheelbuilding faster, more accurate and more satisfying. I do it by sampling digital indicators, rendering the data in useful ways, and injecting domain-specific insights. The UI interaction happens by foot pedal so my paradigm retains the traditional way of working with your hands.

    Hey, maker here. After launching a daily word search game, I randomly thought of this math game while driving. Finally got around to making it and I think it turned out pretty cool. It’s a math search game that’s meant to help you practice your quick addition, subtraction, multiplication, and division skills. I’m hoping it’ll help people (even those like me who aren’t big on math) learn and increase their speeds. (There are also some settings you can enable to make the game harder) If you try it out, please let me know if you found it fun, if you have anything you’d like me to add, or if you…
