2022-01-04Style: Remove inconsistently used `@author` docstringsRémi Verschelde
Each file in Godot has had multiple contributors who co-authored it over the years, and the information of who was the original person to create that file is not very relevant, especially when used so inconsistently. `git blame` is a much better way to know who initially authored or later modified a given chunk of code, and most IDEs now have good integration to show this information.

Happy new year to the wonderful Godot community! 2020 has been a tough year for most of us personally, but a good year for Godot development nonetheless with a huge amount of work done towards Godot 4.0 and great improvements backported to the long-lived 3.2 branch. We've had close to 400 contributors to engine code this year, authoring near 7,000 commit! (And that's only for the `master` branch and for the engine code, there's a lot more when counting docs, demos and other first-party repos.) Here's to a great year 2021 for all Godot users 🎆
2020-05-14Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocksRémi Verschelde
Which means that reduz' beloved style which we all became used to will now be changed automatically to remove the first empty line. This makes us lean closer to 1TBS (the one true brace style) instead of hybridating it with some Allman-inspired spacing. There's still the case of braces around single-statement blocks that needs to be addressed (but clang-format can't help with that, but clang-tidy may if we agree about it). Part of #33027.

Happy new year to the wonderful Godot community! We're starting a new decade with a well-established, non-profit, free and open source game engine, and tons of further improvements in the pipeline from hundreds of contributors. Godot will keep getting better, and we're looking forward to all the games that the community will keep developing and releasing with it.

2019-03-27KinematicBody performance and quality improvementsDaniel Rakos
With this change finally one can use compound collisions (like those created by Gridmaps) without serious performance issues. The previous KinematicBody code for Bullet was practically doing a whole bunch of unnecessary calculations. Gridmaps with fairly large octant sizes (in my case 32) can get up to 10000x speedup with this change (literally!). I expect the FPS demo to get a fair speedup as well. List of fixes and improvements: - Fixed a general bug in move_and_slide that affects both GodotPhysics and Bullet, where ray shapes would be ignored unless the stop_on_slope parameter is disabled. Not sure where that came from, but looking at the 2D physics code it was obvious there's a difference. - Enabled the dynamic AABB tree that Bullet uses to allow broadphase collision tests against individual shapes of compound shapes. This is crucial to get good performance with Gridmaps and in general improves the performance whenever a KinematicBody collides with compound collision shapes. - Added code to the broadphase collision detection code used by the Bullet module for KinematicBodies to also do broadphase on the sub-shapes of compound collision shapes. This is possible thanks to the dynamic AABB tree that was previously disabled and it's the change that provides the biggest performance boost. - Now broadphase test is only done once per KinematicBody in Bullet instead of once per each of its shapes which was completely unnecessary. - Fixed the way how the ray separation results are populated in Bullet which was completely broken previously, overwriting previous results and similar non-sense. - Fixed ray shapes for good now. Previously the margin set in the editor was not respected at all, and the KinematicBody code for ray separation was complete bogus, thus all previous attempts to fix it were mislead. - Fixed an obvious bug also in GodotPhysics where an out-of-bounds index was used in the ray result array. There are a whole set of other problems with the KinematicBody code of Bullet which cost performance and may cause unexpected behavior, but those are not addressed in this change (need to keep it "simple"). Not sure whether this fixes any outstanding Github issues but I wouldn't be surprised.

Using `misc/scripts/fix_headers.py` on all Godot files. Some missing header guards were added, and the header inclusion order was fixed in the Bullet module.

2017-11-04Bullet physics engine implementationAndreaCatania
This is a bullet wrapper that allows Godot to use Bullet physics and benefit about all features. Also it support all specific Godot physics functionality like multi shape body, areas, RayShape, etc.. It improve the Joints, Trimesh shape, and add support to soft body even if Godot is not yet ready to it.
