At the beginning of December we [merged a big work on physics (and many related features)](https://castle-engine.io/wp/2022/12/08/physics-merge-pull-request-with-552-commits-see-you-this-saturday-on-our-open-meeting/) and later we merged another big work on physics _joints_ (another big merge, 363 commits). It’s time to provide to you some readable summary of all the improvements 🙂

I also wrote a nice [documentation about physics](https://castle-engine.io/physics). And remember [that we feature a lot of physics examples](https://github.com/castle-engine/castle-engine/tree/master/examples/physics).

New physics (and related) features:

1. New components, available in both editor and code, to control the physics.

2. New components have also additional features, like:

3. Colliders are also visualized. Juse use _“Physics-\>Show Colliders”_ menu item.

4. There’s a new _“Physics Simulation”_ mode available in the editor. Start it to make physics work. You _can_ click around and modify the design even while the physics is running — this is a feature, albeit a bit dangerous one: the design is restored to the original state when physics stops.

5. There is a new API to apply forces from code. This can be used to simulate forces other than gravity. For example wind or explosion.

6. Third person navigation:

7. Changing the transformation (like `TCastleTransform.Translation`) of an object affected by physics is now more reliable. You can do it even if `TCastleRigidBody.Dynamic`=true (although you should refrain from doing it every frame — the entire point of `TCastleRigidBody.Dynamic`=true is that you allow physics to affect it).

8. We have new and powerful methods `TCastleAbstractRootTransform.PhysicsRayCast` and `TCastleRigidBody.PhysicsRayCast`. They return `TPhysicsRayCastResult` packed with information.

9. The editor has now big buttons to

10. Utility [FindAllBehaviors](https://castle-engine.io/apidoc/html/CastleTransform.TCastleTransform.html#FindAllBehaviors-TCastleBehaviorClass-) (see [physics\_explosion](https://github.com/castle-engine/castle-engine/tree/master/examples/physics/physics_explosion) for demo)

11. Editor adjusts to dark theme (if you request it from your OS) better.

12. We define new useful methods to override on behaviors, making behaviors more useful:

13. Finally, physics objects also support [joints](https://castle-engine.io/physics#_joints) to connect and constrain rigid bodies.

14. Deprecation notice:
