Cross-platform (desktop, mobile, console) 3D and 2D game engine supporting many asset formats (X3D, glTF, Spine...) and using modern Object Pascal

Castle Game Engine

"Castle Game Engine" ( https://castle-engine.io/ ) is an open-source 3D and 2D game engine.

We have many graphic features (shadows, mirrors, screen effects...) and support many data formats for game assets (X3D, glTF, VRML, Collada, Spine...). We have many user-interface components, with a powerful viewport to display 3D or 2D content, with many optional features (like instant creatures with simple walking and attacking intelligence). We're cross-platform (desktop, mobile, Nintendo Switch).

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

Compiling

There are a couple of options. See the "Getting Started" page https://castle-engine.io/documentation.php for details. In short:

• Use our Castle Game Engine Editor to design and build your applications. See https://castle-engine.io/manual_editor.php .

• Use our Castle Game Engine command-line build tool to build your applications. See https://github.com/castle-engine/castle-engine/wiki/Build-Tool .

  The build tool and editor use the project settings from the CastleEngineManifest.xml file.

• Use Lazarus ( https://www.lazarus-ide.org/ ).

  Install in Lazarus two packages:

  • packages/castle_base.lpk and
  • packages/castle_components.lpk

  Also, compile (but don't install) this package:

  • packages/castle_window.lpk

• Use FPC fpmake / fppkg. See https://github.com/castle-engine/castle-engine/wiki/FpMake

License

The engine is available on the terms of LGPL >= 2 license with "static linking exception". This is the same license as used by FPC RTL and Lazarus LCL. In short, you can make commercial and closed-source games using the engine, you only have to share your modifications to the engine core. See COPYING.md for details.

Have fun!
