2022-07-29Remove Signal connect bindsJuan Linietsky
Remove the optional argument p_binds from `Object::connect` since it was deprecated by Callable.bind(). Changed all uses of it to Callable.bind()
2022-07-25Remove ThreadWorkPool, replace by WorkerThreadPoolJuan Linietsky
The former needs to be allocated once per usage. The later is shared for all threads, which is more efficient. It can also be better debugged.
2022-06-20Clean up Hash Functionsreduz
Clean up and do fixes to hash functions and newly introduced murmur3 hashes in #61934 * Clean up usage of murmur3 * Fixed usages of binary murmur3 on floats (this is invalid) * Changed DJB2 to use xor (which seems to be better)
2022-05-20Add a new HashSet templatereduz
* Intended to replace RBSet in most cases. * Optimized for iteration speed

2022-05-18Add motion parameter to toggle whether recovery is reported as a collisionRicardo Buring
This makes the intent explicit in each use case.
2022-05-16Replace most uses of Map by HashMapreduz
* Map is unnecessary and inefficient in almost every case. * Replaced by the new HashMap. * Renamed Map to RBMap and Set to RBSet for cases that still make sense (order matters) but use is discouraged. There were very few cases where replacing by HashMap was undesired because keeping the key order was intended. I tried to keep those (as RBMap) as much as possible, but might have missed some. Review appreciated!

2022-05-02Style: Partially apply clang-tidy's `cppcoreguidelines-pro-type-member-init`Rémi Verschelde
Didn't commit all the changes where it wants to initialize a struct with `{}`. Should be reviewed in a separate PR. Option `IgnoreArrays` enabled for now to be conservative, can be disabled to see if it proposes more useful changes. Also fixed manually a handful of other missing initializations / moved some from constructors.

2022-03-23Add protective checks for invalid handle use in BVHlawnjelly
Adds DEV_ASSERTS that will halt at runtime if the BVH is misused with invalid IDs, and adds ERR_FAIL macros to prevent calling with invalid IDs. Any such misuse is a bug in the physics, but this should flag any errors quickly.

Fix rigid body ray cast CCD in 2D and 3D Godot Physics
2021-12-10Fix rigid body ray cast CCD in 2D and 3D Godot PhysicsPouleyKetchoupp
For 2D: Raycast CCD now works the same as in 3D, it changes the body's velocity to place it at the impact position instead of generating a contact point that causes a wrong push back. For both 2D and 3D: The raycast CCD process reads and modifies body velocities, so it needs to be moved to pre_solve() instead of setup() to be processed linearly on the main thread, otherwise multithreading can cause some CCD results to be randomly lost when multiple collisions occur.
2021-12-10Improve RigidDynamicBody force and torque APIPouleyKetchoupp
Makes the API for forces and impulses more flexible, easier to understand and harmonized between 2D and 3D. Rigid bodies now have 3 sets of methods for forces and impulses: -apply_impulse() for impulses (one-shot and time independent) -apply_force() for forces (time dependent) applied for the current step -add_constant_force() for forces that keeps being applied each step Also updated the documentation to clarify the different methods and parameters in rigid body nodes, body direct state and physics servers.

2021-12-09Handle test body motion with 0 marginPouleyKetchoupp
Margin needs to have a high enough value for test body motion to work properly (separate using the margin, move without then gather rest info with the margin again). Fixes issues with test motion returning no collision in some cases with margin equal to 0.
2021-12-07Add physics solver settings to project settingsPouleyKetchoupp
Helps with discovery and setup of physics solver settings, in a specific project settings section for both 2D and 3D. Other changes for cleanup: -Removed unused space parameters in 3D SPACE_PARAM_BODY_ANGULAR_VELOCITY_DAMP_RATIO SPACE_PARAM_CONSTRAINT_DEFAULT_BIAS -Added custom solver bias for Shape3D (same as Shape2D) -Improved documentation for solver settings
2021-12-03Update space parameters in 2D and 3DPouleyKetchoupp
Clarified space parameters for contacts and added missing ones. List of changes: -Add contact bias to space parameters -Add solver iterations to space parameters, instead of a specific physics server function -Renamed BODY_MAX_ALLOWED_PENETRATION to CONTACT_MAX_ALLOWED_PENETRATION to make it consistent with other contact parameters
2021-12-03Improve RigidDynamicBody contacts in 2D and 3DPouleyKetchoupp
Changed the algorithm for solving contacts to keep previous contacts as long as they are under the max separation threshold to keep contact impulses more consistent and contacts more stable. Also made 2D consistent with 3D and changed some default parameters: -Contact bias is now 0.8 instead of 0.3 to avoid springy contacts -Solver iterations are 16 instead of 8 by default for better stability Performance considerations: Tested with stress tests that include lots of contacts from overlapping bodies. 3D: There's no measurable difference in performance. 2D: Performance is a bit lower (close to 10% slower in extreme cases) The benefit for 2D physics to be much more stable outweighs the slight decrease in performance, and this could be alleviated by changing the algorithm to use jacobians for contact solving to help with cache efficiency and memory allocations.
2021-11-25Fix RigidDynamicBody gaining momentum with bouncePouleyKetchoupp
Bounce calculation now uses the previous frame's velocity, so it's consistent with the actual motion of the bodies involved and not the yet-to-be-applied forces. When bounce is 1, using the current velocity was causing the new forces (including gravity) to be taken into account, which lead to the bounce velocity to be higher than the falling velocity at the moment of impact, adding more and more energy over time.

2021-11-17Fix rest_info returning no result with high margin and low motionPouleyKetchoupp
Apply the same logic as in test_body_motion to make sure the minimum allowed depth doesn't filter out all contacts in this case.
2021-11-16Fix physics BVH pairing for teleported or fast moving objectsPouleyKetchoupp
Updating the broadphase to find new collision pairs was done after checking for collision islands, so it was working in most cases due to the pairing margin used in the BVH, but in case of teleported objects the narrowphase collision could be skipped. Now it's done before checking for collision islands, so we can ensure that broadphase pairing has been done at the same time as objects are marked as moved so their collision can be checked properly. This issue didn't happen in the Octree/HashGrid because they do nothing on update and trigger pairs directly when objects move instead.
