ChunkEdge

A Rust framework for building Minecraft: Java Edition servers.

Built on top of Bevy ECS, ChunkEdge is an effort to create a Minecraft-compatible server completely from scratch in Rust. You can think of ChunkEdge as a game engine for Minecraft servers similar to the Minestom project. It doesn’t do much by default, but by writing game logic yourself and leveraging Bevy’s powerful plugin system, you can make almost anything.

Opinionated features like dynamic scripting, dedicated executables, and vanilla game mechanics are all expected to be built as optional plugins. This level of modularity is desirable for those looking to build highly custom experiences in Minecraft such as minigame servers.

[!WARNING]
ChunkEdge is still early in development with many features unimplemented or incomplete. Expect to encounter bugs, limitations, and breaking changes. At the moment, ChunkEdge is only compatible with Minecraft 1.21.5. The aim is to support the latest stable version of Minecraft. For now, you can use a proxy (for example ViaProxy combined with Velocity) to allow players on both older and newer clients to connect to your server.

Goals

ChunkEdge aims to be the following:

• Complete. Abstractions for the full breadth of the Minecraft protocol.
• Flexible. ChunkEdge can be easily extended from within user code. Direct access to the Minecraft protocol is provided.
• Modular. Pick and choose the components you need. Some crates can also be reused in projects that don’t use the full ChunkEdge framework.
• Intuitive. An API that is easy to use and difficult to misuse. Extensive documentation and examples are important.
• Efficient. Optimal use of system resources with multiple CPU cores in mind.
• Up-to-date. Tries to be up-to-date with the most recent stable version of Minecraft. Currently Minecraft 1.21.5 is supported. Support for multiple versions at once is not planned. However, you can use a proxy (for example ViaProxy combined with Velocity) to allow players on both older and newer clients to connect to your server.

Current Status

Here are some noteworthy achievements:

• chunkedge_nbt: A speedy new library for Minecraft’s Named Binary Tag (NBT) format.
• Authentication, encryption, and compression
• Block states
• Chunks
• Entities and metadata
• 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.
• Inventories
• Items
• Particles
• Anvil file format (read-only)
• Proxy support (Velocity)

Getting Started

Running the Examples

After cloning the repository, run this command to try an example.

cargo r -r --example parkour

List all available examples with:

cargo run --example

Recommended examples to try are parkour, game_of_life, terrain, and cow_sphere.

Open your Minecraft client and connect to the address localhost. If all goes well, you should be able to play the example.

Adding ChunkEdge as a Dependency

Since ChunkEdge is still unstable and in early development, we don’t yet publish crate versions.

To use the most recent development version, add ChunkEdge as a git dependency.

[dependencies]
chunkedge = { git = "https://github.com/ChunkEdge/ChunkEdge", rev = "<COMMIT_HASH>" }

Documentation from the main branch is available here.
