Oxide

The Oxide Minecraft Server aims to implement a fully functional Minecraft Server, compatible with the latest version, from scratch entirely in Rust.

You can try it right now by joining play.oxide.thetxt.io

This repository contains the Oxide Minecraft Server, as well as all auxillary parts described below. Each of these parts live in their own subdirectory.

The main purpose of this repository is for me to learn and share my gained knowledge through a series of YouTube videos.

Please don't run it with any worlds you aren't prepared to lose.

Features

Currently implemented

This list is non-exhaustive, but covers the most important parts.

• Multiple players with basic interactions (see item in hand or armor and their position)
• Chat (without encryption) and some basic commands
• Placing and breaking blocks (very few block state rules implemented)
• Loading and saving vanilla worlds
• Creative mode
• Basic survival features (WIP)
• Block entities (chests, furnaces (only smelting raw iron with coal) and signs for now)
• Entities with basic AI
• Crafting & Smelting
• Nether and End dimensions

Missing

These will be implemented in the nearish future

• More commands
• Protocol encryption / online mode
• Packet compression
• More block state rules
• Rules on which blocks can be placed on which other blocks

Running

For testing

You can run the server by just executing cargo run in the server subdirectory.

For "production"

Remember, this is very alpha software that will at some point delete your worlds or damage them otherwise!

I recommend running through docker using the provided docker-compose.yml file. There is also a docker-compose.build.yaml file that builds a fresh image locally, instead of using the pre-built image from the gibthub container registry.

Configuration

Configuration is handled through environment variables.

Key	Default value	Format	Notes
OXIDE_LISTEN_ON	0.0.0.0:25565	[ip]:[port]
OXIDE_WORLD_PATH	./world	any path	./ must be explicitly stated
OXIDE_SAVE_SECONDS	60	Whole seconds
OXIDE_MOTD	Hello oxide!	String	Quick and dirty hack, Freaks out on windows if string is contained in quotes or includes spaces and i don't know why...
OXIDE_DEFAULT_GAMEMODE	survival	survival OR creative OR adventure OR spectator	The gamemode players that connect for the first time get assigned

Repository contents

server

This is the actual Minecraft server.

proxy

This is a very basic proxy to intercept communication between the minecraft client and server. It listens on localhost port 35565 and connects to a server running on localhost port 25565, without a way to configure these at the moment. It has access to all the packet deserialization/serialization code which makes this proxy useful for testing their implementations against the official minecraft server.

lib

A library containing common functionality that is shared between the server and proxy. This mostly includes the logic to deserialize and serialize packets and some common types.

basic_types

As the name suggests, this library crate contains some basic types that are used by all other crates.

data_generator_tools

Extremely rough program to generate the data library crate from the official servers generated json files. It expects a directory official_server in the root of the project. The jar of the desired official server then needs to be downloaded into this directory. Executing java -DbundlerMainClass="net.minecraft.data.Main" -jar official_server.jar -all then generates the required json files. Afterwards you can run cargo run -p data_generator_tools to generate/update the data crate.

data

Another library that contains data on biomes, blocks, items, block entities, inventories, loot tables, recipes and tags. It is mostly generated using the data_generator_tools crate.

Dependencies

This project aims to minimally rely on third party dependecies. Everything related to Minecraft is fully custom. There are still some third party dependencies:

• flate2 for compression and decompression
• dashmap for parallel hashmaps
• rand for random number generation

The jzon crate is also used in the data_gnerator_tools utility for working with the generated json files from the official Minecraft server.

This project wouldn't be possible without the contributors of the Minecraft wiki.
