Physics2DDirectBodyState
========================

**Inherits:** :ref:`Object<class_Object>`

Direct access object to a physics body in the :ref:`Physics2DServer<class_Physics2DServer>`.

Description
-----------

Provides direct access to a physics body in the :ref:`Physics2DServer<class_Physics2DServer>`, allowing safe changes to physics properties. This object is passed via the direct state callback of rigid/character bodies, and is intended for changing the direct state of that body. See :ref:`RigidBody2D._integrate_forces<class_RigidBody2D_method__integrate_forces>`.

Method Descriptions
-------------------

.. _class_Physics2DDirectBodyState_method_add_central_force:

- void **add_central_force** **(** :ref:`Vector2<class_Vector2>` force **)**

Adds a constant directional force without affecting rotation.

----

.. _class_Physics2DDirectBodyState_method_add_force:

- void **add_force** **(** :ref:`Vector2<class_Vector2>` offset, :ref:`Vector2<class_Vector2>` force **)**

Adds a positioned force to the body. Both the force and the offset from the body origin are in global coordinates.

----

.. _class_Physics2DDirectBodyState_method_add_torque:

- void **add_torque** **(** :ref:`float<class_float>` torque **)**

Adds a constant rotational force.

----

.. _class_Physics2DDirectBodyState_method_apply_central_impulse:

- void **apply_central_impulse** **(** :ref:`Vector2<class_Vector2>` impulse **)**

- void **apply_impulse** **(** :ref:`Vector2<class_Vector2>` offset, :ref:`Vector2<class_Vector2>` impulse **)**

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.

Applies a rotational impulse to the body.

Returns the collided shape's metadata. This metadata is different from :ref:`Object.get_meta<class_Object_method_get_meta>`, and is set with :ref:`Physics2DServer.shape_set_data<class_Physics2DServer_method_shape_set_data>`.

----
