In all physics servers, body_get_direct_state() now silently returns
nullptr when the body has been already freed or is removed from space,
so the client code can detect this state and invalidate the body rid.
In 2D, there is no change in behavior (just no more errors).
In 3D, the Bullet server returned a valid direct body state when the
body was removed from the physics space, but in this case it didn't
make sense to use the information from the body state.
NodePath properties are designed to be relative to the given node, so
validity checks are failing in the editor for Polygon2D nodes, which are
relative to the Skeleton2D node rather than the Polygon2D node.
Fixed by saving bone paths as String properties instead of NodePath.
Shouldn't cause a difference for performance since NodePath properties
are technically saved as String anyway.
(cherry picked from commit 8d9619ad46)
Changes the Path2D drawing to use POLYLINE instead of thick lines.
Add a path to translate thick lines (that are not using anti-aliasing) to draw as polygons instead. This should be faster because polygons can be batched.
Sets `AlignOperands` to `DontAlign`.
`clang-format` developers seem to mostly care about space-based indentation and
every other version of clang-format breaks the bad mismatch of tabs and spaces
that it seems to use for operand alignment. So it's better without, so that it
respects our two-tabs `ContinuationIndentWidth`.
Fix some typoed names from the doc
Add _index to "index" parameters of *_shape_* signals, this is both in doc and in the template. This makes the code, signature and doc easier to understand
Add method to get Node from the _index params of those signals. This was not as easy to find as one would expect. Putting this information where it is needed will help.
In case the reference is stored in script, create a new instance to
avoid overriding the previous values.
Otherwise, re-use the reference as before to avoid extra allocations.
Fixes#43733: "creating SpatialMaterial in a separate thread creates invalid
shaders (temporarily)."
The bug occurred because various setters called in materials' constructors add
materials to queues that are processed on the main thread. This means that
when the materials are created in another thread, they can be processed on the
main thread before the constructor has finished.
The fix adds a flag to affected materials that prevents them from being added
to the queue until their constructors have finished initialising all the
members.
For both 2D and 3D, three methods are added:
- `get_floor_angle` on `KinematicBody` to get the floor angle.
- `get_angle` on `KinematicCollision` to get the collision angle.
- `get_last_slide_collision` to quickly get the latest collision of `move_and_slide`.
Applying the platform velocity when leaving the platform floor should be
done after snapping to keep things consistent.
Now it's done in both 2D and 3D, as it's already done in 2D on master.
This comment is useful to determine the origin of ShaderMaterials
converted from built-in material types (such as CanvasItemMaterial
or SpatialMaterial).
The Godot version is also included in case the shader needs to be
regenerated with a newer engine version.
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.

When synchronizing KinematicBody motion with moving the platform using
direct body state, only the linear velocity was taken into account.
This change exposes velocity at local point in direct body state and
uses it in move_and_slide to get the proper velocity that includes
rotations.
* Safe and unsafe motion are calculated by dichotomy with a limited
number of steps. It's good for performance, but on long motions that
either collide near the beginning or near the end, the result can be
very imprecise.
* Now a factor 0.25 or 0.75 is used to converge faster when this case
happens, which allows longer motions to get more accurate collision
detection.
* Makes snap collision more precise, and helps with cases where diagonal collision on the border of a platform can lead to the character being stuck.
Additional improvements to move_and_slide:
* Handle slide canceling in move_and_collide with 0 velocity instead of
not applying it.
* Better handling of snap with custom logic to cancel sliding.
* Remove small jittering when using stop on slope, by canceling the
motion completely when the resulting motion is less than margin instead
of always projecting to the up direction (in both body motion and snap).

Make sure the direction of the motion is preserved, unless the depth is
higher than the margin, which means the body needs depenetration in any
direction.
Also changed move_and_slide to avoid sliding on the first motion, in
order to avoid issues with unstable position on ground when jumping.

Fixing by applying the movement in two steps, first the platform
movement, and then the body movement. Plus, add the platform movement
when we are on_wall.
The situation when multiple current Camera2Ds were in the scene was not dealt with. This could leave several cameras with their current bool set, and each competing to update the viewport scroll, in a random / accidental fashion.
This PR standardises the rule that the most recent current Camera2D added to the scene tree takes over the current status, and sets all other current cameras in the scene tree to non-current. This makes the bools correct, and also prevents the competition over viewport scroll.
The new color for screen drawing was chosen to be easier to distinguish
from the 2D viewport limits.
This also makes lines less opaque when the Camera2D has the Current
property enabled. The increased line width is enough to spot the
camera easily, and the increased opacity on top of that felt obnoxious.

We've been using standard C library functions `memcpy`/`memset` for these since
2016 with 67f65f6639.
There was still the possibility for third-party platform ports to override the
definitions with a custom header, but this doesn't seem useful anymore.
Backport of #48239.
When AnimatedSprite2D::play() was called before SpriteFrames has been initialized, a crach occurred (issue #46013).
Modification : An error message on null check test has been added to prevent crash.
Fix#46013.

The logic for internal process and internal physics process in Camera2D was very buggy and convoluted for historical reasons.
This is a cleanup to make the logic simpler and easier to follow.
More work is needed to make sure that those options actually solve users' issues, so we prefer to remove the options for 3.2.4 and revisit for a future release.
If true, collision shapes are shown in the editor and at run-time.
Requires Visible Collision Shapes to be enabled in the Debug menu,
for collision shapes to be visible at run-time.
When one of the bodies exited the tree, the corresponding node path was
reset instead of just resetting the joint from the physics server. That
was causing the node path to be reset on scene switch when one of the
bodies is under the joint in the scene tree.
The rendering/quality/2d section of project settings is becoming considerably expanded in 3.2.4, and arguably was not the correct place for settings that were not really to do with quality.
3.2.4 is the last sensible opportunity we will have to move these settings, as the only existing one likely to break compatibility in a small way is `pixel_snap`, and given that the whole snapping area is being overhauled we can draw attention to the fact it has changed in the release notes.
Class reference is also updated and slightly improved.
`pixel_snap` is renamed to `gpu_pixel_snap` in the project settings and code to help differentiate from CPU side transform snapping.
Two common problems have emerged as a result of transform snapping:
1) Camera jitter with a camera following a snapped object
2) Pixel gaps between e.g. a platform and a player, where a platform rounds down and a player rounds up
Using round seems to greatly reduce problems due to camera jitter. It also may prove better for pixel gaps because pixel art is often designed on a grid, so whole numbers are too expected, which are unstable with floor().
Having white or strongly desaturated debug collision shape color
setting would make it harder to visualize enabled / disabled state.
This change makes it easier to visualize enabled / disabled state
by reducing the alpha color by half when disabled.

- Based on C++11's `atomic`
- Reworked `SafeRefCount` (based on the rewrite by @hpvb)
- Replaced free atomic functions by the new `SafeNumeric<T>`
- Replaced wrong cases of `volatile` by the new `SafeFlag`
- Platform-specific implementations no longer needed

- Based on C++11's `mutex`
- No more need to allocate-deallocate or check for null
- No pointer anymore, just a member variable
- Platform-specific implementations no longer needed
- Simpler for `NO_THREADS`
- `BinaryMutex` added for special cases as the non-recursive version
- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.
This change does two things:
1. Properly update the internal shape data using _update_in_shape_owner
when updating a shape (in 2D it was resetting one way collision)
2. Avoid unnecessary updates when calling set_shape with the same shape,
which happens each time a shape property is modified
(e.g shape.extents.x = ...)
