Castle Game Engine is a cross-platform game engine designed for creating interactive 3D and 2D applications. It supports multiple platforms, including Windows, Linux, macOS, and BSD. The engine uses Pascal as its main language and offers integrated tools for scene design, rendering, and physics.
- Advanced 3D rendering. The engine supports 3D graphics with dynamic lighting, shadows, particle effects, and custom shaders. It includes compatibility with formats such as glTF, X3D, and Collada for importing models.
- 2D graphics support. Allows the development of 2D games with sprites, scrolling layers, and animations. Includes tools for texture manipulation and collisions.
- Visual scene editor. Provides a graphical interface for designing levels and arranging objects in 3D space. Users can adjust properties, lights, and cameras without writing code.
- Integrated physics system. Uses the Kraft physics engine to simulate collisions, gravity, and object movement. Supports rigid bodies, triggers, and joints.
- Cross-platform. Projects can be exported to Windows, Linux, macOS, and BSD. No code changes are required for different platforms.
- Pascal language. Code is written in Object Pascal, with a well-documented API and examples to make development easier.
- Asset import. Supports a variety of formats, including OBJ, PNG, JPEG, WAV, and OGG. Resources can be bundled into compressed archives for distribution.
- Spatial audio. Includes a 3D sound system with attenuation and Doppler effects. Compatible with OpenAL for accurate playback.
- Lua scripting. Lets you add game logic through Lua scripts without recompiling the main project.
- Networking and multiplayer. Offers functions for TCP/IP and UDP connections, enabling the creation of online games with data synchronization.
- User interface. Provides predefined components for menus, buttons, and HUDs. Elements can be customized using CSS styles.
- Virtual reality. Compatible with VR devices such as Oculus Rift and OpenVR, with specific settings for stereoscopic rendering.
Castle Game Engine was created by Michalis Kamburelis in 2005 as an open-source project. The engine is written in Object Pascal and uses the Free Pascal Compiler to generate binaries. Over the years, it has added support for new technologies such as Vulkan, WebGL, and virtual reality. The community contributes plugins, tutorials, and improvements to the official repository.
