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.
Adds the ability to directly add disabled shapes to a collision object. Before this commit a shape has always been assumed to be enabled and had to be disabled in an extra step.
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.
This allows most demos to run without any ubsan or asan errors. There
are still some things in thirdpart/ and some things in AudioServer that
needs a look but this fixes a lot of issues. This should help debug less
obvious issues, hopefully.

Nothing really relevant for us, but it's not a bad consistency
improvement anyway so worth taking.
This commit makes operator[] on Vector const and adds a write proxy to it. From
now on writes to Vectors need to happen through the .write proxy. So for
instance:
Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;
Failing to use the .write proxy will cause a compilation error.
In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.
_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.
Also ensure that get_scale doesn't arbitrarlity change the signs of scales, ensuring that the combination of get_rotation and get_scale gives the correct basis.
Added various missing functions and constructors.
Should close#17968.
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.
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.
