SoftBody support in GodotPhysics 3D
|
|
Helps a lot with soft bodies and generally useful to avoid shapes to go
through the ground in certain cases.
Added an option in ConcavePolygonShape to re-enable backface collision
on specific bodies if needed.
|
|
- Fixed SoftBody surface update with new rendering system
- Added GodotPhysics implementation for SoftBody
- Added support to get SoftBody rid to interact with the physics server
- Added support to get SoftBody bounds from the physics server
- Removed support for unused get_vertex_position and get_point_offset
from the physics server
- Removed SoftBody properties that are unused in both Bullet and
GodotPhysics (angular and volume stiffness, pose matching)
- Added RenderingServerHandler interface to PhysicsServer3D so the physics servers don't need to reference the class from SoftBody node directly
|
|
|
|
Previously godot would try to access
`CollisionObjectBullet::bt_collision_object` even if it was null.
Fixes #46651

-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).

Fix cast_motion sometimes failing

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 🎆

Set Bullet collision shape index to zero when using a single shape or ConcavePolygonShape
|
|
|
|
Remove any constraints connected to a Bullet body when removing it
|
|
Since we clone the environments to build thirdparty code, we don't get an
explicit dependency on the build objects produced by that environment.
So when we update thirdparty code, Godot code using it is not necessarily
rebuilt (I think it is for changed headers, but not for changed .c/.cpp files),
which can lead to an invalid compilation output (linking old Godot .o files
with a newer, potentially ABI breaking version of thirdparty code).
This was only seen as really problematic with bullet updates (leading to
crashes when rebuilding Godot after a bullet update without cleaning .o files),
but it's safer to fix it everywhere, even if it's a LOT of hacky boilerplate.

- Fixes Godot physics failing when the cast Shape is inside of, or
already colliding with another Shape.
- Fixes Bullet physics failing when there is no motion.
- Ensures Godot and Bullet physics behave the same.
- Updates the documentation to exclude the caveats for the failures and
differences.

It was due to main_shape_changed being called two times for each
added body. The first time it disables ccd, which sets the internal ccd
threshold to be 10000. The second time, it enables ccd again because
the internal threshold is > 0.
Bodies are now consistently set with a ccd threshold of 0 when ccd is
disabled.
This was causing crashing asserts in Bullet when adding bodies in some
scenarios, in btVector3::normalize():
btAssert(!fuzzyZero());
These crashes will still happen with ccd enabled.

Remove the unnecessary sync() and the restrictions it imposes on 3D Physics.
|
|
-Removed FuncRef, since Callable makes it obsolete
-Removed int_types.h as its obsolete in c++11+
-Changed color names code

|
or ConcavePolygonShape3D.
|
|
Removed make_binders and the old style generated binders.
