    Defold

    Defold

    Free game engine for development of desktop, mobile, and web games

    Game logic is written in Lua (with optional native extensions in C/C++ when needed), and the engine uses a component-based system and a message-passing paradigm to manage object interactions — a design that promotes loosely-coupled, reactive game code rather than traditional heavy OOP. Defold is optimized for efficiency: exported games tend to have small binary size and low memory use, making it appealing for mobile, HTML5/web, and lightweight games.

    Iris

    Iris

    A modern shaders mod for Minecraft compatible with existing OptiFine

    Iris was created to fill a void that I saw in the Minecraft customization and graphical enhancement community: the lack of an open-source shaders mod that would let me load my favorite shader packs on modern versions of the game, while retaining performance and compatibility with modpacks. OptiFine, the current dominant mod for loading shader packs, has restrictive licensing that firmly stands in the way of any sort of tinkering, and is fairly notorious for having compatibility issues with...

    osu!framework

    osu!framework

    A game framework written with osu! in mind.

    ...This framework is intended to take steps beyond what you would normally expect from a game framework.

Any of the osu! code that is deemed useful to other game projects will live in this framework project. Anywhere we implement graphical components, they will be displayed with a generic design and will be derivable for further customization.

    Oak

    Oak

    A pure Go game engine

    Oak has recently brought in dependencies that include C code, but we still describe the engine as a Pure Go engine, which at face value seems contradictory. Oak's goal is that, by default, a user can pull down the engine and create a fully functional game or GUI application on a machine with no C compiler installed, so when we say Pure Go we mean that, by default, the library is configured so no C compilation is required, and that no major features are locked behind C compilation. ...
