  • veloren

    An open world, open source voxel RPG inspired by Dwarf Fortress and Cube World. This repository is a mirror. Please submit all PRs and issues on our GitLab page.

    • Project mention: MagicaVoxel – A free voxel art editor and interactive path tracing renderer | news.ycombinator.com | 2023-10-28

    I've never used it, but (from what I've seen) is a great tool for modeling Voxels.

    Shameless plug: The format (and the tool) had been used with great success in Veloren, an Open Source Voxel MMORPG written in rust (https://www.veloren.net/). The artist team has made great assets for the game and landscapes for the release parties.

    Your should check out the project, it is really cool.

    • Project mention: Show HN: CloudTabs Web Browser – a web browser on every website | news.ycombinator.com | 2024-04-04

    Is that right? Could be a recent acquire if it's DOM mirroring.

    I heard CF acquired S2 a few years ago, and what S2 did is they created a WebAssembly binary that composited the browser SKIA draw instructions on the client, and streamed the SKIA draw instructions from the server. Not without its issues, but certainly useful.

    What we do is just stream pixels to the client. Yes it's expensive in terms of bandwidth, relatively. But the advantage is simplicity. And with a close server and bandwidth trending faster and cheaper, with the increasing drive to video consumption across media, I don't see bandwidth as an issue.

    If you're interested, our code is on GitHub: https://github.com/BrowserBox/BrowserBox

  • open-match

    Flexible, extensible, and scalable video game matchmaking.

    • Project mention: Edit This Blog Post | news.ycombinator.com | 2024-02-06

    Absolutely! The real complexity comes from conflict resolution. If someone edits the top, and someone else edits the bottom, which version do you go with? What if they're editing the same area? Entire companies exist to provide elegant solutions to this[0], so it's no simple task.

    • Project mention: Is there any game where you can design your own weapons/vehicles? | /r/computerwargames | 2023-12-10

    It is more an RTS than a 'classical' wargame, but you could do it in Warzone 2100. It is old for now (but it was very fun in 2000s). It could be fun for you today. There is a free and open source version : https://wz2100.net/ .

    • Project mention: Shiftnanigans - 2D Platformer Randomizer | /r/rust | 2023-06-24

    I made a 2D platformer randomization crate called Shiftnanigans (https://github.com/AustinHellerRepo/Shiftnanigans) as part of my work on the open source game Jumpy (https://github.com/fishfolk/jumpy). Within the map editor of Jumpy, the Randomize button will randomize the placement of tiles and elements, maintaining the general structures of the map. I've described the two abstract concepts and sets of structs used to accomplish this functionality below. This is just a general overview, but I am happy to elaborate further if anyone has questions about the algorithms and data structures used.
