Minecrust ⛏️

A Minecraft clone that runs in the browser, written from scratch in Rust.

Works on desktop and mobile.

Why?

This project is primarily for learning and proving to myself that I can write a game engine from scratch. Furthermore, I wanted to learn Rust, make the game easily accessible in the browser, and make it presentable like a real product.

As for my motivation, I've always had a deep respect for game developers. I used to believe that games and graphics were a dark art accessible only to a select few. But then I learned a bit about graphics from my work at Mighty, and I got inspired by jdh on Youtube who wrote his own Minecraft clone. I started to think, "Whoa, this isn't a dark art. I can do this too!"

Cool Features

• Infinite, procedurally generated terrain. Dynamic memory management to achieve infinite world
• Physics simulation and collision detection for the playable character
• Custom shaders for shadows, diffuse reflection, and specular reflection
• It's fast. Profile-guided optimization to achieve >30 FPS on most phones and laptops
• A single Rust codebase that runs on all platforms: Web and Native (MacOS, Windows, Linux). Huge thanks to wgpu and wasm-pack for enabling this
• ~~Beautiful~~ Custom artwork by yours truly
• You can build a house in it 🏠
• "Completed" in ~100 hours, but non-consecutively. 60% Summer 2022, 20% Winter 2022, 20% Winter 2023

How to Run

Native App

cargo run --release

Web App

yarn start

Things to improve that I will realistically never do

• Increase draw distance on mobile
• Probably need to implement view-frustum culling for this to be feasible
• Camera movement with external mouse feels very sensitive, could use smoothing
• Ability to save the world and load it up later
• Better shadows
• Antialiasing
• Draw at a further distance
• More block types
• Better terrain generation
• Ability to choose a different seed so terrain is generated differently
• Better art? lol
