2021-10-04Fix physics glitch with TileMap moving platformsPouleyKetchoupp
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.
2021-10-04Script interface improvements for test body motionPouleyKetchoupp
-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)
2021-09-30Remove shape metadata from 2D physics serverPouleyKetchoupp
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.

2021-09-27Improved logic for CharacterBody collision recovery depthPouleyKetchoupp
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

2021-09-06Proper support for custom mass properties in 2D/3D physics bodiesPouleyKetchoupp
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

Clean physics direct body state usage in 2D and 3D physics
2021-08-25Clean physics direct body state usage in 2D and 3D physicsPouleyKetchoupp
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.
2021-08-24Rename RayShape to SeparationRayShapePouleyKetchoupp
Makes it clearer that it's used for special cases when picking a collision shape.
2021-08-24Rename slips_on_slope to slide_on_slopePouleyKetchoupp
Also added some precision to the documentation.
2021-08-24Fix CharacterBody motion with RayShapePouleyKetchoupp
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).
2021-08-24Fix RayShape collision detectionPouleyKetchoupp
One-way collision is disabled for both rigid bodies and character bodies. Kinematic margin is now applied to ray shapes to help getting consistent results in slopes and flat surfaces. Convex shapes don't return inverted normals when a segment test starts inside (raycasting will be made consistent in a separate patch). Ray shapes also discard contacts when fully contained inside a shape and when the contact direction is inverted, so the behavior is consistent with all shape types. Now they always separate only when intersecting the top of a shape (for downward rays).
2021-08-15API improvement on physics, mainly CharacterBodyfabriceci
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.
2021-08-10Remove infinite inertia and ray shapes from CharacterBodyPouleyKetchoupp
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.
2021-07-19One-directional collision layer check for rigid bodies and soft bodiesPouleyKetchoupp
Check for each body individually if it collides with the other one or ignores it. When a body is being ignored, the other body's mass is considered infinite when applying impulses to avoid extra overlapping.

2021-07-15Fixing 2D moving platform logicfabriceci
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.
2021-07-01Make move_and_slide collision detection more accuratePouleyKetchoupp
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).

Fix and clean disabled shapes handling in godot physics servers
2021-06-28Fix move_and_collide causing sliding on slopesPouleyKetchoupp
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. Co-authored-by: fabriceci <fabricecipolla@gmail.com>
2021-06-22Fix and clean disabled shapes handling in godot physics serversPouleyKetchoupp
In 3D, disabled shapes are now not added to the broadphase anymore. Since they are removed right away when disabled, no need to check for disabled shapes for any query that comes from the broadphase. Also Fixes raycast queries returning disabled shapes. In 2D, disabled shapes where already not added to the broadphase. Remove the same unnecessary checks as in 3D. Overall harmonized API for disabled shapes in the physics servers and removed duplicate method.
2021-06-04More explanatory names for RigidBody modesPouleyKetchoupp
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).

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.
2021-02-09Fix 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.

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 🎆
2020-11-27Fix cast_motion sometimes failingMarcel Admiraal
- 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.

2020-05-14Style: Enforce braces around if blocks and loopsRémi Verschelde

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.

2020-02-25Variant: Added 64-bit packed arrays, renamed Variant::REAL to FLOAT.Juan Linietsky
- 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.
