The complete engine manual is on https://castle-engine.io/ . If you have any questions, talk with us on Discord or forum.


Visual editor

Design 3D and 2D games and user interfaces (with automatic scaling, anchors). Build and deploy the same project for multiple platforms. Integrate with various IDEs (Lazarus, Delphi, Visual Studio Code...).


A lot of components to design viewport contents (3D and 2D world, using scenes, cameras, navigation, primitives, lights...) and user inteface (buttons, images, labels...).

Lots of ways to define data

Use 3D models, 2D animations, sprite sheets. Great integration with authoring tools like Blender or shops like Sketchfab thanks to using open standards like glTF and X3D.

Graphic effects

Composable shader effects, shadows, mirrors, physically based rendering, bump mapping, gamma correction...


Target any platform (desktop: Windows, Linux, macOS, FreeBSD, Raspberry Pi, mobile: Android, iOS, console: Nintendo Switch). Work on any desktop platform. WebGL and Oculus (VR) are coming as targets soon.

Clean and fast code

Native clean object-oriented programming language with modern Object Pascal. Fast builds, fast execution out-of-the-box.

Open source and friendly to continuous integration

Tooling friendly to continuous integration. Command-line build tool, Jenkins, GitHub actions. Engine is completely open-source and can be used to make any (including proprietary) applications.

haven't used yet, what code does it use

(1 edit)

The engine, and your games, are written using modern Object Pascal. See https://castle-engine.io/features , https://castle-engine.io/modern_pascal .

Note that we plan to release new engine version, 7.0-alpha.2, soon (in a week).

It will be available here (on itch.io) as well as on our webpage https://castle-engine.io/ . For today, if you want to try out the engine, I would recommend checking out our snapshot version, which is the main download on our https://castle-engine.io/ .

I see that there is an Open Collective for Castle Game Engine but I don't see it listed on your home page. Is it still an active and valid way to donate ?



Yes, donating through https://opencollective.com/castle-engine is welcome. We have a few ways to donate, listed on https://castle-engine.io/donate_other.php .  On the main engine WWW page we focus on https://www.patreon.com/castleengine as this is our preferred method for donation, but all alternative ways listed above are good as well :) Thank you!

Is it possible to build games without code?

Not really. You will need to write some code if you want to do anything beyond a demo. Most of the logic is in the code.

That said, you can start with some example that gives you most of what you  need. For example our "fps_game" example (once you download the engine from https://castle-engine.io/ , it is in "examples/fps_game/" subdirectory) can be extended a lot by just editing the data files. You can add creatures, items by just editing  respective XML files (docs on https://castle-engine.io/creating_data_levels.php , https://castle-engine.io/creating_data_resources.php ).

You could extend fps_game into a full FPS game without much additional code. (But you will still need something, e.g. to show "win" screen, or to code what using new items will do etc.)

Note that the engine version on Itch.io is rather old now (I want to update it once we release engine 7.0). So please download engine from https://castle-engine.io/ now. We've made a lot of new features since 6.4 release ( https://github.com/castle-engine/castle-engine/wiki/New-Features-in-Castle-Game-... ) and  we work on official 7.0 release now.

Note to whoever reads this: the above comment is outdated. The current version on itch.io is "7.0-alpha.1", and it is good :) Still you can always get even more recent ("7.0-alpha-snapshot") version from https://castle-engine.io/.

Screenshots of these looks like one PSX game. Can you make a sequel to this Engine?

The next release of this engine is already in-progress, see our news ( https://castle-engine.io/wp/ ) :) You can already try it, using the code from GitHub ( https://github.com/castle-engine/castle-engine/ ).

its not working for me in my files i font even know where to find the application

Instructions how to use the engine are on https://castle-engine.io/ , in particular see the "getting started" page ( https://castle-engine.io/documentation.php ) and the manual ( https://castle-engine.io/manual_intro.php ).

There is no visual application distributed with Castle Game Engine. You usually install Lazarus ( https://www.lazarus-ide.org/ ) to have an environment to edit and compile Castle Game Engine games.

If you expected a visual editor included inside the engine, like Unity3d editor --- I'm sorry, we don't have it yet. But we are working in it, see our plans for 2018 https://castle-engine.io/wp/2017/12/23/plans-6-4-release-asap-visual-editor-soon... :)

Note to whoever reads this: the above comment is outdated. The current engine (from this itch.io page, or from https://castle-engine.io/) features a cool visual editor to design your games visually. See https://castle-engine.io/manual_editor.php .
