Two main changes:
- Better handling of concave shapes to make sure the queries don't
return a triangle index instead of shape index.
Note: A concave shape within a compound shape will always return a shape
index of 0 because of Bullet limitations.
- Extra check for compound shapes in some queries to avoid undefined
behavior, because the shape index can have an uninitialized value with
convex shapes in some cases.
Same thing that was already done in 2D, applies moving platform motion
by using a call to move_and_collide that excludes the platform itself,
instead of making it part of the body motion.
Helps with handling walls and slopes correctly when the character walks
on the moving platform.
Also made some minor adjustments to the 2D version and documentation.

Check for each body individually if it collides with the other one or
ignores it.
When a body is being ignored, the other body's mass is considered
infinite when applying impulses to avoid extra overlapping.
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 🎆
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.
- Added code handling non-compound collision to recover_from_penetration_ray()
which is now needed due to the optimization avoiding the use of compound
collisions when only a single collision shape is used.
- Removed arbitrary margin applied in the collision algorithm of RayShapes
which causes jittered movement. For lack of a better replacement and for
lack of any explanation on why it has been introduced, it's now using the
shape's margin property instead which is small enough to not show visible
jitter.
- Tried to get rid of inconsistent uses of the collision margin.
- Removed hack from GodotDeepPenetrationContactResultCallback::addContactPoint
for RayShape collision as it's no longer needed as the collision algorithm
of RayShapes correctly calculates the contact normal for a while now.
Fixes#25227.
Fixes some out-of-bounds problems when there are more collisions than
have been requested for. This extends what has been done in 444b8471a3.
Fixesgodotengine/godot#23990
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.
