Castle Game Engine

Castle Game Engine is a cross-platform 3D and 2D game engine.

• You can use any 3D or 2D software to create models in various formats: glTF, X3D, VRML, Spine JSON, Collada.... In particular creating game models in Blender is fully supported, through the glTF format.
• The engine can be used to compile desktop (Linux, Windows, macOS), mobile (Android, iOS) and consoles (Nintendo Switch) games.
• You can design and build applications in a visual editor. The editor utilizes a command-line build tool under the hood. The build tool calls FPC and some other tools to compile and run the project.
• Many graphic effects are available: physically-based rendering, shadows, mirrors, bump mapping, shader effects, gamma correction. Rendering is done through OpenGL or OpenGLES.
• Numerous services, like in-app purchases and game services, are available on mobile devices. See Android servcies, iOS services.
• The user interface is cross-platform and supports anchors and automatic scaling.

The engine is open-source. The engine may be used under GNU LGPL with "static linking exception", just like FPC RTL and Lazarus LCL. So you can make both open- and closed-source games.
