<description>
Base class of [SkeletonModifier3D]s that has some joint lists and applies inverse kinematics. This class has some structs, enums, and helper methods which are useful to solve inverse kinematics.
[b]Note:[/b] The IK classes that extend this handle rotation only, with bone lengths cached. It means that a position movement between processed chains can cause unintended movement.

The constant force that always affected bones. It is equal to the result when the parent [Skeleton3D] moves at this speed in the opposite direction.
This is useful for effects such as wind and anti-gravity.
