Castle Game Engine

"Castle Game Engine" is an open-source cross-platform 3D and 2D game engine.

We have many graphic features (physically-based rendering, shadows, mirrors, screen effects, gamma correction...) and support many data formats for game assets (glTF, X3D, Spine JSON, Collada, ...). We have many user-interface components, with a powerful viewport to display 3D or 2D content. We're cross-platform (desktop, mobile, Nintendo Switch).

See https://castle-engine.io/features.php for the complete list of engine features.

Documentation:

  • Manual is the most recommended way to learn the engine.

  • API reference.

    It is also available offline in the engine archive (if you downloaded the binary engine release), just open the file doc/reference/index.html in your WWW browser.

  • Numerous examples are provided in the examples/ subdirectory.

  • Guide to creating game data.
