You love the super-long news titles, right? 🙂 Again I have a backlog of announcements to do, to communicate everything happening around the engine development. There will be more news in 2024 (stay tuned for traditional _“summary of this year, plans for next”_), for today a bag of improvements to announce:
1. We have a new unit `CastleTransformManipulate` with 2 new components: `TCastleTransformHover` (visualize the `TCastleTransform` we hover over) and `TCastleTransformManipulate` (visualize selection and move / rotate / scale `TCastleTransform`).
Together, they allow you to implement selection / manipulation of 3D objects in your own applications just like the [Castle Game Engine editor](https://castle-engine.io/editor) does.
Their usage is rather simple:
- just create `TCastleTransformManipulate`, call `TCastleTransformManipulate.SetSelected`, set `TCastleTransformManipulate.Mode`.
- just create `TCastleTransformHover`, set `TCastleTransformHover.Current`.
Practical examples of using them are in:
- [examples/ifc](https://github.com/castle-engine/castle-engine/tree/master/examples/ifc), example of using [IFC](https://castle-engine.io/ifc) in our engine.
- [example of our engine integration with mORMot](https://github.com/castle-engine/castle-and-mormot-collaborative-editing/)
Note: We still work on 2 examples above (we want to improve some things in IFC support, and we want to make mORMot example really support collaborative editing). But their usage of `CastleTransformManipulate` is now completely stable 🙂
2. We support toggling any `TIndexedFaceSetNode` to display as wireframe.
3. We have fixed [Steam achievements](https://castle-engine.io/steam) usage (getting, setting) with Delphi.
4. I made a presentation about our engine at the beginning of December at [Meetup Delphi in Bielsko-Biała (Poland)](https://evenea.pl/pl/wydarzenie/meetupdelphi). This was a bigger presentation about engine features, physics, Blender, Sketchfab, Steam integration.

A sims type game is coming…
I leave that twisted thought here… 🙃
