Physics FPS above 1000 cause the whole project to slow down
and are not very practical in the first place (since no CPU currently
available can keep up).
Updated the `SceneTree.quit()` method to include a note that on iOS this method won't work as apps are expected to be closed via the Home button, not programmatically.
Update Popup.xml
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.
* GIProbe is now VoxelGI
* BakedLightmap is now LightmapGI
As godot adds more ways to provide GI (as an example, SDFGI in 4.0), the different techniques (which have different pros/cons) need to be properly named to avoid confusion.
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.
In this PR:
- Removed rset
- rpc_config can now optionally configure transfer mode
(reliable/unreliable/ordered) and channel (channels are not actually
implemented yet.)
- Refactor how the RPC id is computed to minimize the logic in Node and
scripts that now only needs a single `get_rpc_methods` function.
