    Redot Engine

    Redot Engine

    Multi-platform 2D and 3D game engine

    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. We...
