RustCraft

Inspiration

Minecraft has inspired countless developers, but most implementations remain tied to Java. We wanted to explore what a modern, high-performance reimplementation could look like using Rust and Vulkan, while staying faithful to the original gameplay and architecture. RustCraft is our attempt to combine memory safety, modern graphics APIs, and clean engine design into a Minecraft-compatible client.

What it does

RustCraft is a Minecraft client reimplemented from scratch in Rust 2021 with a Vulkan rendering backend.

Current features include:

  • Chunk rendering
  • Modern Vulkan renderer
  • Camera and player movement
  • Resource loading compatible with Minecraft assets
  • Cross-platform architecture
  • Modular engine designed for future scripting and modding support

The long-term goal is to become a performant, extensible Minecraft-compatible client rather than simply a graphical demo.

How we built it

RustCraft is built entirely in Rust 2021 Edition.

Key technologies include:

  • Ash for Vulkan bindings
  • winit for window creation and input
  • nalgebra for mathematics
  • image for texture loading
  • Cargo as the build system and package manager

Build:

cargo build --release

The engine is designed around modern rendering principles instead of directly porting Minecraft's original OpenGL pipeline.

Challenges we ran into

Rewriting Minecraft from scratch presented many challenges:

  • Translating Minecraft's OpenGL renderer into Vulkan
  • Designing an efficient chunk renderer
  • Matching Minecraft's rendering behavior and camera system
  • Implementing frustum culling and face culling correctly
  • Managing Vulkan synchronization and GPU resources
  • Balancing performance, safety, and maintainability

Many seemingly simple Minecraft mechanics required extensive reverse engineering to faithfully reproduce.

Accomplishments that we're proud of

  • Successfully rebuilt a Minecraft client in Rust
  • Implemented a Vulkan-based rendering pipeline from scratch
  • Created a modular engine architecture for future expansion
  • Achieved stable rendering with modern graphics APIs
  • Built a strong foundation for scripting, networking, and modding

Most importantly, we demonstrated that Rust is an excellent choice for building large-scale game engines.

What we learned

Throughout this project, we gained valuable experience with:

  • Vulkan graphics programming
  • Modern rendering architecture
  • GPU resource management
  • Rust ownership and lifetime design
  • Game engine architecture
  • Reverse engineering Minecraft's rendering and gameplay systems

This project also deepened our appreciation for the engineering behind the original Minecraft.

What's next for RustCraft

Our roadmap includes:

  • World generation
  • Multiplayer protocol compatibility
  • Optimized chunk meshing
  • Dynamic lighting
  • Resource pack support
  • Lua scripting API
  • Plugin and modding system
  • Better performance optimizations
  • Cross-platform releases

Our long-term vision is to build a fast, modern, open-source Minecraft-compatible client powered entirely by Rust and Vulkan.
