PhysicsDirectBodyState2D
Provides direct access to a physics body in the PhysicsServer2D.
class PhysicsDirectBodyState2DProvides 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 RigidBody2D, and is intended for changing the direct state of that body. See _integrateForces(state:).

Conformances
protocol CustomStringConvertibleA type with a customized textual representation.
protocol EquatableA type that can be compared for value equality.
protocol HashableA type that can be hashed into a
Hasherto produce an integer hash value.protocol Identifiable<ID>A class of types whose instances hold the value of an entity with stable identity.
protocol VariantRepresentableTypes that conform to VariantRepresentable can be stored directly in
Variantwith no conversion. These include all of the Variant types from Godot (for exampleGString,Rect,Plane), Godot objects (those that subclass SwiftGodot.Object) as well as the built-in Swift types UInt8, Int64 and Double.protocol VariantStorableTypes that conform to VariantStorable can be stored in a Variant and can be extracted back out of a Variant.

func addConstantCentralForce(Vector2) Adds a constant directional force without affecting rotation that keeps being applied over time until cleared with
constant_force = Vector2(0, 0).func addConstantForce(Vector2, position: Vector2) Adds a constant positioned force to the body that keeps being applied over time until cleared with
constant_force = Vector2(0, 0).func addConstantTorque(Double) Adds a constant rotational force without affecting position that keeps being applied over time until cleared with
constant_torque = 0.func applyCentralForce(Vector2) Applies a directional force without affecting rotation. A force is time dependent and meant to be applied every physics update.
