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

.. _class_PhysicsDirectBodyState_method_add_central_force:

- void **add_central_force** **(** :ref:`Vector3<class_Vector3>` force **)**

Adds a constant directional force without affecting rotation.

This is equivalent to ``add_force(force, Vector3(0,0,0))``.

.. _class_PhysicsDirectBodyState_method_add_force:

- void **add_force** **(** :ref:`Vector3<class_Vector3>` force, :ref:`Vector3<class_Vector3>` position **)**

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

.. _class_PhysicsDirectBodyState_method_add_torque:

- void **add_torque** **(** :ref:`Vector3<class_Vector3>` torque **)**

Adds a constant rotational force without affecting position.

.. _class_PhysicsDirectBodyState_method_apply_central_impulse:

- void **apply_central_impulse** **(** :ref:`Vector3<class_Vector3>` j **)**

Applies a single directional impulse without affecting rotation.

This is equivalent to ``apply_impulse(Vector3(0, 0, 0), impulse)``.

.. _class_PhysicsDirectBodyState_method_apply_impulse:

- void **apply_impulse** **(** :ref:`Vector3<class_Vector3>` position, :ref:`Vector3<class_Vector3>` j **)**

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. The position uses the rotation of the global coordinate system, but is centered at the object's origin.

.. _class_PhysicsDirectBodyState_method_apply_torque_impulse:

- void **apply_torque_impulse** **(** :ref:`Vector3<class_Vector3>` j **)**

Apply a torque impulse (which will be affected by the body mass and shape). This will rotate the body around the vector ``j`` passed as parameter.

.. _class_PhysicsDirectBodyState_method_get_contact_collider:

- :ref:`RID<class_RID>` **get_contact_collider** **(** :ref:`int<class_int>` contact_idx **)** const

Returns the collider's :ref:`RID<class_RID>`.

.. _class_PhysicsDirectBodyState_method_get_contact_collider_id:

- :ref:`int<class_int>` **get_contact_collider_id** **(** :ref:`int<class_int>` contact_idx **)** const

Returns the collider's object id.

.. _class_PhysicsDirectBodyState_method_get_contact_collider_object:

- :ref:`Object<class_Object>` **get_contact_collider_object** **(** :ref:`int<class_int>` contact_idx **)** const

Returns the collider object.

.. _class_PhysicsDirectBodyState_method_get_contact_collider_position:

- :ref:`Vector3<class_Vector3>` **get_contact_collider_position** **(** :ref:`int<class_int>` contact_idx **)** const

Returns the contact position in the collider.

.. _class_PhysicsDirectBodyState_method_get_contact_collider_shape:

- :ref:`int<class_int>` **get_contact_collider_shape** **(** :ref:`int<class_int>` contact_idx **)** const

Returns the collider's shape index.

.. _class_PhysicsDirectBodyState_method_get_contact_collider_velocity_at_position:

- :ref:`Vector3<class_Vector3>` **get_contact_collider_velocity_at_position** **(** :ref:`int<class_int>` contact_idx **)** const

Returns the linear velocity vector at the collider's contact point.

.. _class_PhysicsDirectBodyState_method_get_contact_count:

- :ref:`int<class_int>` **get_contact_count** **(** **)** const

Returns the number of contacts this body has with other bodies.

**Note:** By default, this returns 0 unless bodies are configured to monitor contacts. See :ref:`RigidBody.contact_monitor<class_RigidBody_property_contact_monitor>`.

.. _class_PhysicsDirectBodyState_method_get_contact_impulse:

- :ref:`float<class_float>` **get_contact_impulse** **(** :ref:`int<class_int>` contact_idx **)** const

Impulse created by the contact. Only implemented for Bullet physics.

.. _class_PhysicsDirectBodyState_method_get_contact_local_normal:

- :ref:`Vector3<class_Vector3>` **get_contact_local_normal** **(** :ref:`int<class_int>` contact_idx **)** const

Returns the local normal at the contact point.

.. _class_PhysicsDirectBodyState_method_get_contact_local_position:

- :ref:`Vector3<class_Vector3>` **get_contact_local_position** **(** :ref:`int<class_int>` contact_idx **)** const

Returns the local position of the contact point.

.. _class_PhysicsDirectBodyState_method_get_contact_local_shape:

- :ref:`int<class_int>` **get_contact_local_shape** **(** :ref:`int<class_int>` contact_idx **)** const

Returns the local shape index of the collision.

.. _class_PhysicsDirectBodyState_method_get_space_state:

- :ref:`PhysicsDirectSpaceState<class_PhysicsDirectSpaceState>` **get_space_state** **(** **)**

Returns the current state of the space, useful for queries.

.. _class_PhysicsDirectBodyState_method_integrate_forces:

- void **integrate_forces** **(** **)**

Calls the built-in force integration code.
