A simple Minecraft engine in Rust

About The Project

Welcome to RUSTCRAFT! Rustcraft is a simple Minecraft engine written in rust using wgpu.

But Why?

I wanted to work on a project to learn more about wgpu as well as practice my Rust skills. I then randomly saw this youtube video and got inspired to try to make a simple Minecraft engine in Rust!

Inspiration

As I explained I was inspired by this video and the corresponding codebase. This is why you will probably see a lot of design similarities between my project and this one. Jdah, your video was awesome. (I also copied his blocks atlas because I liked it a lot).

Current State

I am pretty happy with the current state of the engine. There are a few problems with it but they are outside of my MVP scope. I am aware that the game is not as efficient and smooth as it should be. I initially set as a goal to not use any threading or unsafe rust. Turns out it is hard to generate the world efficiently without any of that so I did end up eventually using rayon (but I should really be using Tokio). This would require some not trivial redesign and maybe I will update this in the future 🤷.

The noise library I am using is also a bit slow. There are some issues with integrating it nicely into a bigger project but I don't really want to write my own noise library right now so this works.

Potential Updates

• Transparent water
• Lighting (real sun or "hacked" lighting)
• Block memory map (saves location of broken/placed blocks)
• Game physics
• additional sprites: (tree, flowers)
• Block selection during placement
• Biomes
• "Real" concurency for chunk generation (Tokio).

• rust
