Reporting rest collision information is needed for move_and_collide and
move_and_slide so floor detection can be done properly, but in the case
of just testing the motion for collision, it makes sense to return false
if the body is able to move all along the path without being stopped.
Updated the logic in test_move and clarified the documentation for
test_move and move_and_collide.
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.
Same as what is already done for shape queries, applied to point and ray
queries. Easier to document and more flexible to add more parameters.
Also expose intersect_point method to script in 3D.
Remove intersect_point_on_canvas in 2D, replaced with a parameter.
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.
This crash occurred when an audio stream finished playing in NOTIFICATION_INTERNAL_PROCESS,
during which it would iterate through a loop of playbacks,
leading to a "finished" signal, which removed the audio player from the tree
which led to a NOTIFICATION_EXIT_TREE,
which would mutate the array of playbacks while within the above loop.
This moves the signal callback outside of the loop which avoids the crash.
Note: previously, the signal was called multiple times if the same player finishes multiple times in one frame. Now it is at most once per frame.
Affects AudioStreamPlayer, AudioStreamPlayer2D and AudioStreamPlayer3D
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`.
Damping values are now non-negative.
Add new properties linear_damp_mode and angular_damp_mode to set the way
RigidDynamicBody and PhysicalBone (2D & 3D) use damping values.
It can now be Combine (default) to add to the default/areas, or Replace
to override the value completely (current behavior).
Fix NavigationObstacle3D to be attached to navigation map - without it
the NavigationObstacle3D is not working.
Replace radius approximation algorithm with simple "radius" property.

Change the unreacheable return value of shape_find_owner()
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.
Added a parameter in test_body_motion to exclude attached objects from
collision, used to avoid collision with all TileMap tiles with moving
platform motion instead of just the one tile the character touches.
Same changes made in 3D for consistency, and handling potential similar
cases.
-Physics servers test body motion use a class to hold parameters instead
of multiple arguments to make it more readable and flexible since there
are many options
-Improved documentation for test body motion and kinematic collision
-Removed read-only properties for body motion results (not handled in
scripts, so they should be get_ methods only instead)
Shape metadata was only used to get tile information when colliding with
tilemaps. It's not needed anymore since there's an API in tilemap using
body ids instead.
_update_kinematic_motion() shouldn't be called in the constructor
It's too early and causes a first call to set the body position to 0.
Then the second call to set the actual position triggers kinematic
motion, colliding with objects on the path to the initial position.
Side effect of sync to physics now enabled by default.
Allows 2D character controller to work without applying gravity when
touching the ground (also more safely in 3D), and collision detection
is more flexible with different safe margin values.
Character body motion changes in 2D and 3D:
-Recovery only for depth > min contact depth to help with collision
detection consistency (rest info could be lost if recovery was too much)
-Adaptive min contact depth (based on margin) instead of space parameter
Extra CharacterBody changes:
-2D: apply changes made in 3D for stop on slope and floor snap that help
fixing some jittering cases
-3D: fix minor inconsistencies in stop on slope and floor snap logic
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.
RigidDynamicBody modes are replaced with several properties to make their
usage clearer:
-lock_rotation: disable body's rotation (instead of MODE_LOCKED)
-freeze: no gravity or forces (instead of MODE_STATIC and MODE_KINEMATIC)
-freeze_mode: Static (can be only teleported) or Kinematic (can be animated)
Also renamed MODE_DYNAMIC_LOCKED to MODE_DYNAMIC_LINEAR in the physics
servers.
Changes:
-Added support for custom inertia and center of mass in 3D
-Added support for custom center of mass in 2D
-Calculated center of mass from shapes in 2D (same as in 3D)
-Fixed mass properties calculation with disabled shapes in 2D/3D
-Removed first_integration which is not used in 2D and doesn't seem to
make a lot of sense (prevents omit_force_integration to work during the
first frame)
-Support for custom inertia on different axes for RigidBody3D
Instead of having a physics node named Static that can be either Static
or Kinematic, AnimatableBody is added again as a separate node:
-Inherited from StaticBody to make its usage clearer
-Still separated from CharacterBody to make its usage more focused
Properly implemented constant velocity for kinematic bodies in godot
physics servers (induced velocity without actually moving).
Also updated description for the different physics nodes to make their
usage clearer.
Use a C++ callback instead of Callable for synchronizing physics nodes' state with physics servers.
Remove usage of PhysicsDirectBodyState in physics nodes when not
necessary.
Store PhysicsDirectBodyState for bodies individually instead of a
singleton to avoid issues when accessing direct body state for multiple
bodies.
PhysicsDirectBodyState is initialized only when needed, so it doesn't
have to be created when using the physics server directly.
Move PhysicsDirectBodyState2D and PhysicsDirectBodyState3D to separate
cpp files.
Make separation ray shapes work properly in move_and_slide, wihtout the
specific code in CharacterBody like before.
Now most of the logic is handled inside the physics server. The only
thing that's needed is to use ray shapes only for recovery and ignore
them when performing the motion itself (unless we're snapping or slips
on slope is on).
* Allows calling into native extensions directly with a pointer
* Makes it easier to implement some APIs more efficiently
* Appears with a "*" in the documentation for the argument.
* Implementing the pointer handling is entirely up to the implementation, although the extension API provides some hint.
* AudioStream has been implemented as an example, allowing to create NativeExtension based AudioStreams.
* `_gui_input`, `_input`, `_unhandled_input` and `_unhandled_key_input` are now regular C++ virutal functions.
* Everything else converted to GDVIRTUAL
* BIND_VMETHOD is gone, always use the new syntax from now on.
Creating `_gui_input` method and using the binder to register events will no longer work, simply override the virtual function now.
This commit adds quite a chunk of modifications to particles
- particle (value + randomness) now use min and max instead
- passing a curveXYZtexture is now possible and will scale particles per-axis
- CPUParticle3D have an optional parameter to split the scale curve per-axis
* New syntax is type safe.
* New syntax allows for type safe virtuals in native extensions.
* New syntax permits extremely fast calling.
Note: Everything was replaced where possible except for `_gui_input` `_input` and `_unhandled_input`.
These will require API rework on a separate PR as they work different than the rest of the functions.
Added a new method flag METHOD_FLAG_OBJECT_CORE, used internally. Allows to not dump the core virtuals like `_notification` to the json API, since each language will implement those as it is best fits.
Changes:
- Rename few methods/property and group them in the editor when it's possible
- Make MotionResult API consistency with KinematicCollision
- Return a boolean in move_and_slide if there was a collision
- New methods:
- get_floor_angle on CharacterBody 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.
- Back to 1-based layer names to make it clearer in editor UI
- Layer bit accessors are renamed to layer value and 1-based too
- Uniform errors and documentation in render and physics
- Fix a few remaining collision_layer used in place of collision_mask
Infinite inertia:
Not needed anymore, since it's now possible to set one-directional
collision layers in order for characters to ignore rigid bodies, while
rigid bodies still collide with characters.
Ray shapes:
They were introduced as a work around to allow constant speed on slopes,
which is now possible with the new property in CharacterBody instead.
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 CharacterBody 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.
In a given quadrant there can be one or more bodies used, and the
process iterated over cells to add the shapes, so the shape index
doesn't necessarily correspond to the polygon shape index.
Instead body shape indices need to be tracked separately.
* Added a new macro SNAME() that constructs and caches a local stringname.
* Subsequent usages use the cached version.
* Since these use a global static variable, a second refcounter of static usages need to be kept for cleanup time.
* Replaced all theme usages by this new macro.
* Replace all signal emission usages by this new macro.
* Replace all call_deferred usages by this new macro.
This is part of ongoing work to optimize GUI and the editor.
Now static body is used for moving platforms through kinematic motion
property, so sync to physics needs to be in StaticBody2D instead of
CharacterBody2D.
Constant kinematic motion is also supported in combination with sync to
physics for smoother movements.
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.
* there is now a more clear distinction between camera_2d and camera_3d functions in the engine code
* simplified camera2d's exported interface - now everything happens directly with the 'current' variable and make_current and clear_current are no longer exposed- there were some situations where calling one instead of set_current would result in incomplete results
* rebased to current godot master
More accurate unsafe motion calculation
* 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).

New property disable_mode to set different behaviors:
Remove: remove from physics simulation
MakeStatic: change body mode to static (doesn't affect area and soft body)
KeepActive: do nothing
Extra change:
Handle disable/enable node state with specific notifications, in order
to differentiate global pause from disabled nodes.
* Functions to convert to/from degrees are all gone. Conversion is done by the editor.
* Use PROPERTY_HINT_ANGLE instead of PROPERTY_HINT_RANGE to edit radian angles in degrees.
* Added possibility to add suffixes to range properties, use "min,max[,step][,suffix:<something>]" example "0,100,1,suffix:m"
* In general, can add suffixes for EditorSpinSlider
Not covered by this PR, will have to be addressed by future ones:
* Ability to switch radians/degrees in the inspector for angle properties (if actually wanted).
* Animations previously made will most likely break, need to add a way to make old ones compatible.
* Only added a "px" suffix to 2D position and a "m" one to 3D position, someone needs to go through the rest of the engine and add all remaining suffixes.
* Likely also need to track down usage of EditorSpinSlider outside properties to add suffixes to it too.
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.

* Renames for 2D and 3D
* Class name was confusing, given both 2D and 3D have a "visible" property that is unrelated to actual on-screen visibility.
* New name makes it clear that this is about visibility on screen.
* Works from RenderinServer
* Accurately tells when on or off-scren, its no longer approximate.
* VisibilityEnabler also simplified to use the process mode instead.
This PR and commit adds a new IK system for 2D with the Skeleton2D node
that adds several new IK solvers, a way to control bones in a Skeleton2D
node similar to that in Skeleton3D. It also adds additional changes
and functionality.
This work was sponsored by GSoC 2020 and TwistedTwigleg.
Full list of changes:
* Adds a SkeletonModifier2D resource
* This resource is the base where all IK code is written and executed
* Has a function for clamping angles, since it is so commonly used
* Modifiers are unique when duplicated so it works with instancing
* Adds a SkeletonModifierStack2D resource
* This resource manages a series of SkeletonModification2Ds
* This is what the Skeleton2D directly interfaces with to make IK possible
* Adds SkeletonModifier2D resources for LookAt, CCDIK, FABRIK, Jiggle, and TwoBoneIK
* Each modification is in its own file
* There is also a SkeletonModifier2D resource that acts as a stack for using multiple stacks together
* Adds a PhysicalBone2D node
* Works similar to the PhysicalBone3D node, but uses a RigidBody2D node
* Changes to Skeleton2D listed below:
* Skeleton2D now holds a single SkeletonModificationStack2D for IK
* Skeleton2D now has a local_pose_override, which overrides the Bone2D position similar to how the overrides work in Skeleton3D
* Changes to Bone2D listed below:
* The default_length property has been changed to length. Length is the length of the bone to its child bone node
* New bone_angle property, which is the angle the bone has to its first child bone node
* Bone2D caches its transform when not modified by IK for IK interpolation purposes
* Bone2D draws its own editor gizmo, though this is stated to change in the future
* Changes to CanvasItemEditor listed below:
* Bone2D gizmo drawing code removed
* The 2D IK code is removed. Now Bone2D is the only bone system for 2D
* Transform2D now has a looking_at function for rotating to face a position
* Two new node notifications: NOTIFICATION_EDITOR_PRE_SAVE and NOTIFICATION_EDITOR_POST_SAVE
* These notifications only are called in the editor right before and after saving a scene
* Needed for not saving the IK position when executing IK in the editor
* Documentation for all the changes listed above.
YSort now has a compatibility alias to Node2D.
Updated TileMap to use the existing Node2D y_sort_enabled property instead
of its own property.
Updated Node2D doc to include the new y_sort_enabled member.
Updated TileMap doc to remove its mention of cell_y_sort.
Deleted YSort doc.
CharacterBody has a linear_velocity property to replace the argument in
move_and_slide.
StaticBody handles reporting linear/angular velocity correctly when
kinematic motion is used (in 3D, used in vehicle and navigation).
Safe margin property on CharacterBody only, used as argument in
move_and_collide.
Removed kinematic_safe_margin in 3D physics server, not really useful
and now harmonized with 2D.
Does the same thing as simulate motion from RigidBody in Kinematic mode,
and CharacterBody (previously KinematicBody).
Added support for constant linear/angular velocity with kinematic_motion
in StaticBody, which moves the body in physics.
Updated documentation for StaticBody and CharacterBody to describe their
functionalities more accurately.
MODE_DYNAMIC instead of MODE_RIGID
MODE_DYNAMIC_LOCKED instead of MODE_CHARACTER
No more special case for sleeping behavior for MODE_DYNAMIC_LOCKED
(MODE_CHARACTER was forcing the body not to sleep, which is redundant
with can_sleep and wasn't done in Bullet).
- snap property to replace move_and_slide_with_snap()
- floor_max_angle, stop_on_slope, infinite_inertia, max_slides,
up_direction properties to replace arguments from move_and_slide()
- up direction now defaults to Vector3.UP and Vector2.UP
PhysicsBody now has methods move_and_collide/test_move and needed
properties for these methods: safe margin, locked axes (3D only).
Moved collision_exceptions from StaticBody to PhysicsBody for 3D
(same as 2D, and conforms to documentation).
RigidBody doesn't have test_motion method anymore, it's now redundant
with PhysicsBody.test_move.
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.
-Mesh2D now works
-MultiMesh2D now works
-Polygon2D now works
-Added hooks for processing 2D particles
-Skeleton2D now works
2D particles still not working, but stuff needed for it is now implemented.
- Move most properties from TileMap to TileSet,
- Make TileSet more flexible, supporting more feature (several
collision layers, etc...),
- Fusion both the TileMap and TileSet editor,
- Implement TileSetSources, and thus a new way to index tiles in the TileSet,
- Rework the TileSet and TileMap editors completely,
- Implement an editor zoom widget (and use it in several places)
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.
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.
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.
Refactors the _notification method in cpu_particles_2d.cpp to use a switch statement for readability and to bring it inline with other classes like node.cpp and timer.cpp.
Implements https://github.com/godotengine/godot-proposals/issues/1835#issuecomment-727186192
* PauseMode is now ProcessMode, containing the following states:
```
PROCESS_MODE_INHERIT, // same as parent node
PROCESS_MODE_NORMAL, // process only if not paused
PROCESS_MODE_PAUSE_ONLY, // process only if paused
PROCESS_MODE_ALWAYS, // process always
PROCESS_MODE_DISABLED, // never process
```
* NOTIFICATION_PAUSED and NOTIFICATION_UNPAUSED are received effectively when the node is paused and unpaused (not any longer when pause mode is set in SceneTree).
* Renamed some nodes that used ProcessMode/process_mode to specify a callback type to ProcessCallback to avoid clashes.
- 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 bool` by the new `SafeFlag`
- Platform-specific implementations no longer needed
Co-authored-by: Hein-Pieter van Braam-Stewart <hp@tmm.cx>
-For inspector refresh, the inspector now detects if a property change by polling a few times per second and then does update the control if so. This process is very cheap.
-For property list refresh, a new signal (property_list_changed) was added to Object. _change_notify() is replaced by notify_property_list_changed()
-Changed all objects using the old method to the signal, or just deleted the calls to _change_notify(<property>) since they are unnecesary now.
-Rendering server now uses a split RID allocate/initialize internally, this allows generating RIDs immediately but initialization to happen later on the proper thread (as rendering APIs generally requiere to call on the right thread).
-RenderingServerWrapMT is no more, multithreading is done in RenderingServerDefault.
-Some functions like texture or mesh creation, when renderer supports it, can register and return immediately (so no waiting for server API to flush, and saving staging and command buffer memory).
-3D physics server changed to be made multithread friendly.
-Added PhysicsServer3DWrapMT to use 3D physics server from multiple threads.
-Disablet Bullet (too much effort to make multithread friendly, this needs to be fixed eventually).
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 = ...)
Fixes#45090
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 🎆
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.
Body transforms from physics are used to setup the joint and they are
only updated before the physics step by default.
Without forcing the transform update, joints could use a previous
position if the body's position was set after it was added to the scene.
3D physics is not affected by this issue.
Also separated Light2D in PointLight2D and DirectionalLight2D.
Used PointLight2D because its more of a point, and it does not work
the same as OmniLight (as shape depends on texture).
Added a few utility methods to Rect2D I needed.
-Allows merging several 2D objects into a single draw operation
-Use current node to clip children nodes
-Further fixes to Vulkan barriers
-Changed font texture generation to white, fixes dark eges when blurred
-Other small misc fixes to backbuffer code.
-Removed normal/specular properties from nodes
-Create CanvasTexture, which can contain normal/specular channels
-Refactored, optimized and simplified 2D shaders
-Use atlas for light textures.
-Use a shadow atlas for shadow textures.
-Use both items aboves to make light rendering stateless (faster).
-Reorganized uniform sets for more efficiency.
Changed CPU velocity calculation for EMISSION_SHAPE_DIRECTED_POINTS
to follow the same logic as in the GPU version:
mat2 rotm;
rotm[0] = texelFetch(emission_texture_normal, emission_tex_ofs, 0).xy;
rotm[1] = rotm[0].yx * vec2(1.0, -1.0);
VELOCITY.xy = rotm * VELOCITY.xy;
Now both CPUParticles2D & CPUParticles3D (z disabled) show the same results
as their GPU counterparts and take the initial velocity settings into account.
`ConvexPolygonShape2D` and `ConcavePolygonShape2D` are only meant to be
used directly in code and not in the editor for physics-based use cases
specifically.
Developers are advised to use `CollisionPolygon2D` instead, which does
generate those shapes under the hood, handling polygon convexivity,
proper orientation etc.
Fixes#36372 as Path2D/Path3D's `curve` property no longer uses a Curve
instance as default value, but instead it gets a (unique) default Curve
instance when created through the editor (CreateDialog).
ClassDB gets a sanity check to ensure that we don't do the same mistake
for other properties in the future, but instead use the dedicated
property usage hint.
Fixes#36372.
Fixes#36650.
Supersedes #36644 and #36656.

I couldn't find a tool that enforces it, so I went the manual route:
```
find -name "thirdparty" -prune \
-o -name "*.cpp" -o -name "*.h" -o -name "*.m" -o -name "*.mm" \
-o -name "*.glsl" > files
perl -0777 -pi -e 's/\n}\n([^#])/\n}\n\n\1/g' $(cat files)
misc/scripts/fix_style.sh -c
```
This adds a newline after all `}` on the first column, unless they
are followed by `#` (typically `#endif`). This leads to having lots
of places with two lines between function/class definitions, but
clang-format then fixes it as we enforce max one line of separation.
This doesn't fix potential occurrences of function definitions which
are indented (e.g. for a helper class defined in a .cpp), but it's
better than nothing. Also can't be made to run easily on CI/hooks so
we'll have to be careful with new code.
Part of #33027.
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.
Using `clang-tidy`'s `modernize-use-default-member-init` check and
manual review of the changes, and some extra manual changes that
`clang-tidy` failed to do.
Also went manually through all of `core` to find occurrences that
`clang-tidy` couldn't handle, especially all initializations done
in a constructor without using initializer lists.
Part of #33027, also discussed in #29848.
Enforcing the use of brackets even on single line statements would be
preferred, but `clang-format` doesn't have this functionality yet.
Skew is x-axis only, because it must be bidirectionally convertible to a 2x3 matrix, but you can subtract it to the rotation to get the effect on y-axis
It changed name as part of the DisplayServer and input refactoring
in #37317, with the rationale that input no longer goes through the
main loop, so the previous Input singleton now only does filtering.
But the gains in consistency are quite limited in the renaming, and
it breaks compatibility for all scripts and tutorials that access
the Input singleton via the scripting language. A temporary option
was suggested to keep the scripting singleton named `Input` even if
its type is `InputFilter`, but that adds inconsistency and breaks C#.

Note: Only replaced 2 instances to test, Node.get_children and TileMap.get_used_cells
Note: Will do a mass replace on later PRs of whathever I can find, but probably need
a tool to grep through doc.
Warning: Mono will break, needs to be fixed (and so do TypeScript and NativeScript, need to ask respective maintainers)
Configured for a max line length of 120 characters.
psf/black is very opinionated and purposely doesn't leave much room for
configuration. The output is mostly OK so that should be fine for us,
but some things worth noting:
- Manually wrapped strings will be reflowed, so by using a line length
of 120 for the sake of preserving readability for our long command
calls, it also means that some manually wrapped strings are back on
the same line and should be manually merged again.
- Code generators using string concatenation extensively look awful,
since black puts each operand on a single line. We need to refactor
these generators to use more pythonic string formatting, for which
many options are available (`%`, `format` or f-strings).
- CI checks and a pre-commit hook will be added to ensure that future
buildsystem changes are well-formatted.
For us, it practically only changes the fact that `A<A<int>>` is now
used instead of the C++03 compatible `A<A<int> >`.
Note: clang-format 10+ changed the `Standard` arguments to fully
specified `c++11`, `c++14`, etc. versions, but we can't use `c++17`
now if we want to preserve compatibility with clang-format 8 and 9.
`Cpp11` is still supported as deprecated alias for `Latest`.
The code above for horizontal movement uses the right margin (_positive_ x direction) when the offset is negative, but vertical movement uses the top margin (_negative_ y direction) when the offset is negative.
The resulting problem is easily seen in the editor — set the drag margins to be asymmetrical, turn on drawing the drag margins, and slide the offsets from -1 to 1 and back. The horizontal offset moves the camera's center between the left and right margins, but the vertical offset gets them backwards and will move the camera outside the margins entirely.
It's tedious work...
Some can't be ported as they depend on private or protected methods
of different classes, which is not supported by callable_mp (even if
it's a class inherited by the current one).
Remove now unnecessary bindings of signal callbacks in the public API.
There might be some false positives that need rebinding if they were
meant to be public.
No regular expressions were harmed in the making of this commit.
(Nah, just kidding.)
Main:
- It's now implemented thanks to `<mutex>`. No more platform-specific implementations.
- `BinaryMutex` (non-recursive) is added, as an alternative for special cases.
- Doesn't need allocation/deallocation anymore. It can live in the stack and be part of other classes.
- Because of that, it's methods are now `const` and the inner mutex is `mutable` so it can be easily used in `const` contexts.
- A no-op implementation is provided if `NO_THREADS` is defined. No more need to add `#ifdef NO_THREADS` just for this.
- `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`.
- Thread-safe utilities are therefore simpler now.
Misc.:
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.
- Every case of lock, do-something, unlock is replaced by `MutexLock` (complex cases where it's not straightfoward are kept as as explicit lock and unlock).
- `ShaderRD` contained an `std::mutex`, which has been replaced by `Mutex`.
Although destructor call was missing, it still doesn't heal #36537 memory leaks. Further description how that might be overcome - on GitHub
Partialy covers #36537
- Renames PackedIntArray to PackedInt32Array.
- Renames PackedFloatArray to PackedFloat32Array.
- Adds PackedInt64Array and PackedFloat64Array.
- Renames Variant::REAL to Variant::FLOAT for consistency.
Packed arrays are for storing large amount of data and creating stuff like
meshes, buffers. textures, etc. Forcing them to be 64 is a huge waste of
memory. That said, many users requested the ability to have 64 bits packed
arrays for their games, so this is just an optional added type.
For Variant, the float datatype is always 64 bits, and exposed as `float`.
We still have `real_t` which is the datatype that can change from 32 to 64
bits depending on a compile flag (not entirely working right now, but that's
the idea). It affects math related datatypes and code only.
Neither Variant nor PackedArray make use of real_t, which is only intended
for math precision, so the term is removed from there to keep only float.
-Texture renamed to Texture2D
-TextureLayered as base now inherits 2Darray, cubemap and cubemap array
-Removed all references to flags in textures (they will go in the shader)
-Texture3D gone for now (will come back later done properly)
-Create base rasterizer for RenderDevice, RasterizerRD
Self-modulation was forcefully used for the curve drawing which
can interfere with scripted drawing. The curve color is specified by
the `draw_line()` method instead.
- Add some missing descriptions.
- Add links to tutorials for ARVR and AnimationTree.
- Style fixes.
- Engine changes:
* Make `AnimationNodeTransition.input_<number>` properties internal
so that they don't appear in the docs. They still appear in the
inspector based on the actual number of inputs requested.
* Drop unimplemented `CPUParticles.flatness`. It's only used for 3D
particles in `ParticlesMaterial`, and thus only relevant for
`CPUParticles3D`.
When there is no collision with a floor the get_floor_normal() function
should return the zero vector to be consistent with get_floor_velocity().
Renames floor_normal to up_direction in all bindings.
Updates the documentation of get_floor_normal() and get_floor_velocity()
to make it clear when the values are valid. Updates the documentation for
move_and_slide() and move_and_slide_with_snap() to use the new up_direction
parameter name.
Some cases were not handled properly for Polygon2D after making changes in common code to fix Line2D antialiasing. Added an option for drawing polygons to differentiate the two use cases.
Fixes#34568
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.
In the 3D version:
- Partially revert #20908 that was reverted in the 2D version as part
of #21653. This ensures that the Vector returned is always perpendicular
to the surface collided with; and not the floor_normal Vector passed to
the function when on a floor.
- Include an update of the floor velocity before multiplying by the time
delta, which was added to the 2D version as part of commit 13a8014.
In the 2D version:
- Use the Vector2.slide() function instead of Vector2.tangent() to adjust
the amount of motion the stop_on_slope undoes to ensure that it is in the
right direction. This is a implementation of the 3D approach from #30588.
- Combine the !found_collision and motion == Vector2() checks for break.
- Other minor formating changes to make the functions look identical.
Also renamed some variables to align with their use.
Polygon2D:
The property wasn't used anymore after switching from canvas_item_add_polygon() to canvas_item_add_triangle_array() for drawing.
Line2D:
Added the same property as for Polygon2D & fixed smooth line drawing to use indices correctly.
Fixes#26823
Particles were processed only on the next frame after the emission started, causing a one frame delay in rendering. Now the first process cycle is started during the same frame, which makes them consistent with Particles & Particles2D.
Fixes#32890
Now using joint_disable_collisions_between_bodies() to reset the exception, because body_remove_collision_exception() was doing only a part of the work.
Fixes#32733
When playing an animation in reverse, the animation initially starts on frame 0. If it loops, it'll play normally by going to the last frame of the animation, but if it does not... it prematurely stops, since it is already on the last frame (for reversed animation) by starting on frame 0.
OpenGL uses the diamond exit rule to rasterize lines. If we don't shift
the points down and to the right by 0.5, the line can sometimes miss a
pixel when it shouldn't. The final fragment of a line isn't drawn. By
drawing the lines clockwise, we can avoid a missing pixel in the rectangle.
See section 3.4.1 in the OpenGL 1.5 specification.
Fixes#32279
Modified Sprite to use "changed" signal instead of _changed_callback to make it work when tool is disabled (change receptors are editor only).
