    Redot Engine

    Redot Engine

    Multi-platform 2D and 3D game engine

    Redot Engine is an open-source game engine that aims to provide a flexible foundation for building games — likely offering a modern, modular structure so developers can compose only the systems they need (rendering, physics, input, scripting, etc.). It is built to give a base framework rather than a full “batteries-included” engine, which makes it suitable for developers who prefer minimalism, want complete control over architecture, or desire to build custom workflows. Because it’s...

    macroquad

    macroquad

    Cross-platform game engine in Rust

    ...A strength of Macroquad is its cross-platform reach: it supports desktop (Windows, Linux, macOS), web (via WebAssembly / HTML5), and mobile (Android, iOS) without requiring platform-specific code. Compilation is relatively fast with minimal dependencies, so small projects or prototypes can spin up quickly. Because it’s “batteries included” for common tasks (rendering, drawing shapes, text, basic UI, game loop), Macroquad works well for rapid prototyping.

    scene-oriented, flexible 3D engine (C++, Python, C#, Java)

    OGRE (Object-Oriented Graphics Rendering Engine) is a scene-oriented, flexible 3D engine written in C++ designed to make it easier and more intuitive for developers to produce games and demos utilizing 3D hardware. The class library abstracts all the details of using the underlying system libraries like Direct3D and OpenGL and provides an interface based on world objects and other intuitive classes. We consider the results of our GL3Plus RenderSystem as the gold standard. The respective...

    Mach Engine

    Mach Engine

    Zig game engine & graphics toolkit

    Mach is a game engine and graphics toolkit written in Zig, built with the goal of enabling high-performance, truly cross-platform 2D, 3D, GUI, and visualization applications. The project aims to deliver a modular, robust foundation where graphics, input, windowing, and rendering are unified under a modern, low-level but ergonomic API. Because Mach is written in Zig (with some shader code / WGSL), it leverages Zig’s performance and modern systems-level features while offering safe-ish abstractions compared to raw graphics APIs. ...

    VatraLib

    VatraLib

    A simple cross-platform game engine for creating old-school 2D games

    VatraLib is a simple and light-weight cross-platform game engine which allows for creating old-school 2D games, such as Jump 'n' Runs, Real-time strategy games, and Shoot 'em ups. The key idea is to provide the developer with low-level functionality - animation control, collision detection and the like - so they can focus on making games instead of re-inventing the wheel. VatraLib has been rewritten from scratch, see current code under "Code".

    Tools and Z80 engine for creating adventure games. (RUST)

    This is an exercise in some advance programming topics using a text adventure as the central result. This originally began as a project to recreate an old BASIC text adventure, on the ZX Spectrum, using Z80. After developing a very simple byte code VM to handle the game interactions, I realised that there was an opportunity to use some more advance techniques, which in turn can lead to some PC based tools.

    LambdaHack

    Haskell game engine library for roguelike dungeon crawlers

    ...You declare what the game world is made of (entities, their relations, physics and lore) and the engine builds the world and runs it. The library lets you compile a ready-to-play game binary, using either the supplied or a custom-made main loop. A couple of frontends are available (SDL2 is the default for desktop and there is a JavaScript browser frontend) and many other generic engine components are easily overridden, but the fundamental source of flexibility lies in the strict and enforced with types separation of engine code from the read-only content and of clients (human and AI-controlled) from the server.

    Ambient

    The multiplayer game engine

    Ambient is an open-source, cross-platform runtime and engine for building and deploying high-performance multiplayer games and 3D applications, using a modern stack built on Rust, WebAssembly (WASM), and WebGPU. It aims to make multiplayer game development accessible and flexible, providing an entity-component-system (ECS) at its core that doubles as a real-time in-game database; everything in the game — from world objects to runtime data — is represented as entities + components, which can be synchronized across clients automatically. Ambient supports a package-based workflow reminiscent of Rust’s crate system, where “packages” bundle code, assets, and schema definitions; this modular design encourages reuse, mixing, and sharing of content. ...

    Modified source engine (2017) developed by valve and leaked in 2020

    The Source Engine repository under that particular GitHub user appears to be a custom (or forked) version of a game engine — likely an engine derived from or inspired by the classic Source engine lineage (or at least the name evokes that lineage). However, publicly-available documentation, community support or clarity about the project’s scope and maturity seems limited: the repo does not clearly advertise a full engine release or wide adoption. As such, it feels more like an experimental or...
