Fix physics queries not filtering out disabled collision shapes
2021-02-17Fix test_body_motion recoveryPouleyKetchoupp
This change makes test_body_motion more reliable when the kinematic body recovers from being stuck. - When recovery occurs, the rest information is generated, in order to make sure collision results from test_move, move_and_collide and move_and_slide are consistent and return a collision in case of overlap. - The new calculation for recovery vector makes sure the recovery is never more than the overlap depth between shapes. This can help with cases where the kinematic body overlaps with several shapes. Recovery is made iteratively, without forcing a full overlap at each step. This helps with getting proper rest information when recovery occurs. - One Way Collision: When attempting motion, contact direction is checked against motion before skipping in order to solve cases where kinematic bodies can sink into one-way collision shapes. Rest info now sets max contact depth in order to properly handle one-way collision. - Low speed motion is now handled in the rest info, by never setting min_allowed_depth lower than motion length. Separation is always applied with full margin, otherwise contact is lost when low speed motion occurs right after higher speed motion. - Similar changes are applied to 3D in order to make 2D and 3D consistent.
2021-02-12Revised cylinder contact point generationPouleyKetchoupp
Cylinder contact points generation is adjusted to make it more stable when standing on triangle meshes. Point-Circle: Switched to simpler plane projection as it's done for Point-Face contact points. It solves some cases where discrepancies between the two points caused the cylinder to jump. Edge-Circle: Same as before, the case for edge has just been moved from Face-Circle to a specific method. Face-Circle: The previous method was clipping edges against the circle, and then tried to add contact points when there wasn't enough support and failed in some cases. Now using a different algorithm which adds proper contact points around the circle more consistently. First, by clipping edges against circle segments using Face-Face algorithm. Second, by clipping edges against the circle plane.
2021-02-10Cylinder support in Godot Physics 3DPouleyKetchoupp
Cylinder collision detection uses a mix of SAT and GJKEPA. GJKEPA is used to find the best separation axis in cases where finding it analytically is too complex. Changes in SAT solver: Added support for generating separation axes for cylinder shape. Added support for generating contact points with circle feature. Changes in GJKEPA solver: Updated from latest Bullet version which includes EPA fixes in some scenarios. Setting a lower EPA_ACCURACY to fix accuracy problems with cylinder vs. cylinder in some cases.
2021-02-10Make Servers truly Thread Safereduz
-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).
2021-02-09Fix physics queries not filtering out disabled collision shapesPouleyKetchoupp
This change allows collide_shape, intersect_shape, cast_motion and rest_info in both 2D and 3D to ignore disabled shapes and make them consistent with the physics simulation. In some other cases, _cull_aabb_for_body is used and filters shapes out internally, but whenever a physics query uses the broadphase directly without calling _cull_aabb_for_body, disabled shapes can be returned and need to be filtered out.

2021-01-07Fix multiple issues with one-way collisionsMarcel Admiraal
For RigidBodies, uses the collision normal determined by relative motion to determine whether or not a one-way collision has occurred. For KinematicBodies, performs additional checks to ensure a one-way collision has occurred, and averages the recovery step over all collision shapes.

2021-01-01Update copyright statements to 2021Rémi Verschelde
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 🎆

2020-05-14Style: Enforce separation line between function definitionsRémi Verschelde
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.
2020-05-14Style: clang-format: Disable KeepEmptyLinesAtTheStartOfBlocksRémi Verschelde
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.

This reverts commit ec7b481170dcd6a7b4cf0e6c1221e204ff7945f3. This was wrong, `d` is not a distance but the `d` constant in the parametric equation `ax + by + cz = d` describing the plane.
