Creating 3D games and applications using Castle Game Engine
- 1. Creating 3D games and applications using Castle Game Engine Michalis Kamburelis
- 3. Me me me ● Castle Game Engine - https://castle-engine.io/ ● PasDoc - https://pasdoc.github.io/ ● Modern Object Pascal Introduction - https://castle-engine.io/modern_pascal ● Web3d member, Khronos<->Web3d liaison (3D standards - glTF , X3D) ● Co-owner of Cat-astrophe Games - https://cat-astrophe-games.com/
- 4. Castle Game Engine Editor + Pascal = game
- 5. Castle Game Engine ● 3D and 2D ● Editor ● Pascal API (all that you can do in editor + much more) ○ For your games and for engine ● Open-source ○ Want to fork to add a project-specific feature? OK. ● Multi-platform ○ Windows, Linux (Raspberry Pi too), FreeBSD, macOS ○ Android, iOS ○ Nintendo Switch ○ Note: Delphi only for Windows now (but see the end!)
- 6. 2023 Editor
- 7. 3D FPS game template ● Views ● Play view ○ Viewport, navigate in 3D ○ Left side: hierarchy with components ■ UI ■ viewport is also UI ■ 3D: transform scenes, cameras, lights ■ drag-and-drop 3D models, images ■ transform, delete, duplicate ■ behaviors attach to transforms, like billboard ○ Right side: properties ○ Bottom: files ■ preview ■ special data directory ■ double click to run view3dscene on scenes
- 8. Video demo (use if live demo fails)
- 9. Run ● From editor ○ Runs configured compiler, like Delphi ● From Delphi ○ DPROJ is generated for you ○ (Note: Delphi Community Edition supports only this way) ● From other editors, like VS Code ○ https://castle-engine.io/vscode ● Just hit F9 from wherever!
- 10. Physics ● Detect collisions using colliders ● React to them ○ things bounce from each other ○ custom actions possible, like on trigger ● Live demo! ● https://castle-engine.io/physics
- 13. Platformer
- 14. FPS game
- 15. 2023 Coding
- 16. Live demo through this ● Empty project ● Use animated glTF from https://quaternius.com/ ● Make basic scene ● Add shadows
- 17. React to key press
- 18. Load models (just change properties you know from editor)
- 20. Play sound ( First setup TCastleSound component at design-time or run-time. )
- 21. Push by physics model under mouse
- 22. Instantiate design (Create first a design my_box.castle-transform)
- 23. 2023 Fresh out of the oven
- 24. Bad chess game https://github.com/castle-engine/bad-chess https://castle-engine.itch.io/bad-chess
- 25. Delphi Linux P.S. WSL rocks for Delphi+Linux (lightweight, comfortable Linux inside Windows), thanks Jim McKeeth
- 26. 2023 Conclusion
- 27. How to make this sustainable? ● We're a community of Pascal developers who are enthusiastic about open-source, games, and Pascal. https://castle-engine.io/talk.php ● Engine is all free and open-source. But we can sponsor open-source work (Andrzej Kilijański, Eugene Loza). We also did commercial games (CAG, https://unholy-society.com/ ). ● Support us: https://www.patreon.com/castleengine ● Want to work together, b2b contract? michalis@castle-engine.io
- 28. Plans ● Material components (shaders, mirrors, easier) ● Steam (for your games, but also for editor!) ● Web platform (target, but also source!) ● Vulkan ● https://castle-engine.io/roadmap
