Valence
A Rust framework for building Minecraft servers
...You can think of Valence as a game engine for Minecraft servers. 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.
