A Rust framework for building Minecraft: Java Edition servers.
Goals
Valence aims to be the following:
- Complete. Abstractions for the full breadth of the Minecraft protocol.
- Flexible. Your use case should be achievable without manually sending and receiving packets or other hacks.
- Minimal. The API surface is small with only the necessities exposed. Opinionated features such as a standalone executable, plugin system, and reimplementation of vanilla mechanics should be built in a separate crate on top of the foundation that Valence provides.
- Intuitive. An API that is easy to use and difficult to misuse. Extensive documentation is important.
- Efficient. Optimal use of system resources with multiple CPU cores in mind.
- Up to date. Targets the most recent stable version of Minecraft. Support for multiple versions at once is not planned (although you can use a proxy).
Current Status
Valence is still early in development with many features unimplemented or incomplete. However, the foundations are in place. Here are some noteworthy achievements:
- A new serde library for Minecraft's Named Binary Tag (NBT) format
- Authentication, encryption, and compression
- Block states
- Chunks
- Entities and tracked data
- Bounding volume hierarchy for fast spatial entity queries
- Player list and player skins
- Dimensions, biomes, and worlds
- JSON Text API
- A Fabric mod for extracting data from the game into JSON files. These files are processed by a build script to generate Rust code for the project. The JSON files can be used in other projects as well.
- Block entities
- Inventory and items
- Proxy support
- Sounds, particles, etc.
- Utilities for continuous collision detection
Here is a short video showing the examples and some of its current capabilities.
Getting Started
Running the Examples
You may want to try running one of the examples. After cloning the repository, run
cargo r -r --example conway
Next, open your Minecraft client and connect to the address localhost
.
If all goes well you should be playing on the server.
Adding Valence as a Dependency
Valence is published to crates.io. Run cargo add valence
to add it to your
project.
Documentation is available here.
