Play Minecraft in Rust - Open Source Engine > TL;DR: Horizon implements Minecraft Java Edition from scratch in Rust, sitting on top of modern graphics APIs like Vulkan and Wgpu while relying on a custom launcher to prepare game assets from an existing user installation. > Best for: Rust developers and Minecraft enthusiasts wanting native performance and programmatic agent control. > Repository snapshot: ⭐ 6 226 stars · 🍴 854 forks · Rust · MIT > Daily picks: Follow GitHub Open Source on Telegram --- What it is Horizon is an independent implementation of Minecraft Java Edition written from scratch in Rust. It bypasses the Java virtual machine to deliver native performance, advanced rendering features, and a programmatic control interface. How it works The engine relies on modern graphics stacks like Vulkan and Wgpu for rendering. It uses a custom launcher to prepare game assets from an existing user installation and employs 281 differential harnesses to check parity against the vanilla game. Key features - Run vanilla world generation, mobs, redstone, and commands without Java - Render distant terrain up to 1024 chunks using modern graphics APIs - Control the game programmatically or over control interfaces using horizon-ctl - Import CurseForge and Modrinth modpacks containing content and data packs - Manage and host servers locally or on a VPS without Java dependencies Getting started Clone the repository from GitHub, ensure you have a Rust toolchain installed, and use the Horizon launcher to prepare your game assets from an existing legitimate installation. When not to use it Do not use this if you expect complete zero-bug compatibility today, as the project is still tracking hundreds of open parity gaps with the original Java release. --- Discuss Which modpack would you test first on a non-JVM engine? - Discuss this pick on Telegram - GitHub repository - Full breakdown Curated from the repository README and metadata. No hands-on test is claimed; evaluate it in a sandbox before production use.

Minecraft in Rust - Open Source Horizon Engine > TL;DR: Horizon replaces the traditional Java runtime environment with a clean-room Rust implementation designed to interface directly with existing vanilla assets, saves, and resource packs. > Best for: Rust developers and Minecraft enthusiasts wanting native performance and programmatic game control. > Repository snapshot: ⭐ 6 107 stars · 🍴 822 forks · Rust · MIT > Daily picks: Follow GitHub Open Source on Telegram --- What it is Horizon is a clean-room reimplementation of Minecraft Java Edition written entirely in Rust. It replaces the traditional Java runtime environment with a high-performance native binary designed to interface directly with existing vanilla assets, saves, and resource packs. How it works By leveraging low-level graphics APIs and rigorous differential testing against vanilla mechanics across 281 harnesses, Horizon achieves full game loop compatibility while bypassing JVM overhead entirely. It reads existing save files and assets natively without requiring translation layers. Key features - Run vanilla worlds, mobs, redstone, and commands natively through a high-performance Rust binary - Automate gameplay or integrate automation via horizon-ctl and Model Context Protocol endpoints - Render distant terrain up to 1024 chunks with custom graphics presets and controller support - Host dedicated servers easily without requiring a Java runtime environment - Import compatible CurseForge and Modrinth modpacks built around data and asset overrides Getting started Clone the repository from GitHub and ensure you have a modern Rust toolchain installed. Build the project using Cargo to launch the binary or configure your server instances. When not to use it While an engineering masterpiece for systems programmers and bot builders, casual players will still encounter missing feature gaps compared to the official client. --- Discuss Would you use Horizon for raw performance or for the native MCP agent control? - More open-source finds on Telegram - GitHub repository - Full breakdown Curated from the repository README and metadata.

Incari Client Now Running On Browser Rust Rewrite Howdy folks, A few days ago, I announced that I had developed a very experimental port of Horizon (horizon-rust/horizon, rewrite of MC in rust) to the browser, showcasing its incredible performance. You can find it here: nobuildersnotools/horizon-web Today, I am announcing that Incari Client now uses this experimental port for an even more experimental Rust option. This brings all of the features from Incari Client to horizon-web, giving you incredible performance while not compromising on the Incari experience. Incari main modules menu, in Rust Demonstrating Incari Cosmetics working in Rust I must emphasize, once again, that this is **EXTREMELY** experimental, and is probably loaded with bugs. Nonetheless, I think it is a great area to invest time and effort in for the payoff in performance and ease of development that it provides. Source code: incari-client/incari-client Play: incariclient.org Note that there is not a single HTML file option for Rust at this time due to some technical constraints, but it is at the top of my list of TODOs.

用 Rust 重写《我的世界》，mod 该怎么接入 原始链接：horizon-rust/horizon Ludovic Marie 在 GitHub 上开源了 Horizon，一个用 Rust 从零重写的《我的世界》Java 版 26.3。它读取同样的存档，遵守同样的规则，生成同样的地形，游戏素材要从你自己购买的正版里提取。仓库 10 月初建立，到现在有五千多颗星。 重写一个游戏不算稀奇，难的是证明你写得和原版一样。Horizon 的办法是差分测试：同一组输入分别喂给 Rust 版和原版的 Java 字节码，逐个子系统比较输出，不一致就算失败。项目有 281 个这样的测试脚本，覆盖地形生成、红石、生物 AI、渲染、指令等，作者说全部通过。其中有一个细节值得一提，Rust 一侧在每个平台上都要模仿 Java 的浮点运算方式。浮点数在不同语言、不同 CPU 上的舍入细节会有出入，差一点，同一个种子生成的地形就不同了。 不过测试通过不等于没有差异。README 写得清楚，100% 指的是测试覆盖到的部分全部一致，另一个工具逐个方法对照原版代码，还找出 833 处玩家能察觉的缺失，比如界面、动物和实体渲染。 这个项目在 X 上被讨论，焦点是 mod。Java 版的 mod 不是调用接口，是改代码：加载器在游戏启动时改写字节码，mixin 技术把代码注入到原本没打算开放的方法里。字节码是 Java 编译后交给虚拟机执行的中间指令。这样做什么都能改，代价是两个 mod 改同一个方法会冲突，游戏一更新，大批 mod 一起失效。Horizon 里没有 Java 类，Fabric、NeoForge 的 jar 包都跑不起来，只有里面的数据和素材能搬过来。 一条帖子说，Horizon 的出路是 WebAssembly 沙箱。WebAssembly 是一种可移植的二进制格式，沙箱可以想成一个隔离的房间，mod 只能用清单里声明过的能力。这个方案存在过，但就在帖子发出后十几个小时，项目在 10 月 29 日从文档里删掉了 WebAssembly 代码 mod。 现在的方案分成两类。内容 mod 只含方块、物品、配方之类的数据，不带代码。需要逻辑的叫原生 mod，用 horizon-mixins 在编译前修改游戏自己的 Rust 源码，挂到具名函数的开头、返回处等位置。它不在沙箱里，启用前启动器会弹出警告，而且每个 mod 要绑定某个具体的提交版本。为了减轻这个负担，项目又提供了一组固定的钩子函数，只增不删，只用钩子的 mod 可以跨版本构建。 我觉得这个转向说明了一个老问题。帖子作者在回复里也承认，正式接口的代价是只能做接口允许的事，mixin 什么都能碰。mod 作者要的是后者，Horizon 最后也回到了注入这条路，只是注入对象从字节码换成了源码。它能不能比 Java 生态更稳定，取决于那组钩子能覆盖多少需求。

Rust Minecraft (Horizon) Ported To Browser Howdy folks, I'm sure some of you have heard about the recent rewrite of all of Minecraft in Rust, through the Horizon project (horizon-rust/horizon). Someone actually made a post on here a few days ago talking about how this would be a great target to run in the browser, so I went out and did just that. Horizon running in the browser To be clear, this is a bit of a burner project for me, and is just a proof of concept at this time. It does not aim to be quality, or provide any kind of special experience. It is just an experiment. Now that being said, I do think there is a lot of potential here, especially on the performance side of things. Some of you probably recognize me as the guy that created Incari Client, so here's an interesting metric: Incari Client world creation time: 7s Horizon Web world creation time: 1s These will obviously change depending on your hardware, and will especially increase on school chromebooks. On this same machine though, the game boots in a fraction of a second. You can try this out for yourself at the links below: incariclient.org web.carrot-craft.org Source code: nobuildersnotools/horizon-web Note that upstream is doing like a hundred commits every four hours, so gameplay fixes should go upstream and not to my repo. Web stuff can be PRed to that repo. I am open to suggestions, but please remember this is not intended to be a polished product...

Quem tiver uma cópia do Minecraft pode agora usar esta versão feita em Rust capaz de correr no PC mais velhote que tenham. Projeto de código aberto que corre em win/mac/linux 👌 horizon-rust/horizon

@quentinoeoeoe @Lucenyanya C’est une version 1:1 et les mods java sont même compatibles. C’est vraiment bien plus performant horizon-rust/horizon
