Open Source Linux Frameworks

EnTT is a header-only, tiny and easy to use library for game programming and much more written in modern C++. Among others, it's used in Minecraft by Mojang, the ArcGIS Runtime SDKs by Esri and the amazing Ragdoll. The entity-component-system (also known as ECS) is an architectural pattern used mostly in game development. This project started off as a pure entity-component system. Over time the codebase has grown as more and more classes and functionalities were added. Statically generated integer identifiers for types (assigned either at compile-time or at runtime). A constexpr utility for human readable resource names. An incredibly fast entity-component system based on sparse sets, with its own pay for what you use policy to adjust performance and memory usage according to the users' requirements. Offers a minimal configuration system built using the monostate pattern.

An open source starter package for creating Minecraft type games, using Unity 3 by Unity Technologies.

Rust framework for building Minecraft: Java Edition servers. Built on top of Bevy ECS, Valence is an effort to create a Minecraft-compatible server completely from scratch in Rust. 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.
