When synchronizing CharacterBody motion with moving the platform using direct body state, only the linear velocity was taken into account. This change exposes velocity at local point in direct body state and uses it in move_and_slide to get the proper velocity that includes rotations.

<description>
|
|
Provides direct access to a physics body in the [PhysicsServer2D], allowing safe changes to physics properties. This object is passed via the direct state callback of dynamic bodies, and is intended for changing the direct state of that body. See [method RigidBody2D._integrate_forces].

<argument index="1" name="position" type="Vector2" default="Vector2(0, 0)" />
|
|
<description>
|
|
Adds a positioned force to the body. Both the force and the offset from the body origin are in global coordinates.

|
|
<argument index="1" name="position" type="Vector2" default="Vector2(0, 0)" />
|
|
<description>
|
|
Applies a positioned impulse to the body. An impulse is time-independent! Applying an impulse every frame would result in a framerate-dependent force. For this reason, it should only be used when simulating one-time impacts (use the "_force" functions otherwise). The offset uses the rotation of the global coordinate system, but is centered at the object's origin.
