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

.. _class_PhysicsBody2D_method_add_collision_exception_with:

.. rst-class:: classref-method

|void| **add_collision_exception_with**\ (\ body\: :ref:`Node<class_Node>`\ ) :ref:`🔗<class_PhysicsBody2D_method_add_collision_exception_with>`

Adds a body to the list of bodies that this body can't collide with.

.. rst-class:: classref-item-separator

----

.. _class_PhysicsBody2D_method_get_collision_exceptions:

.. rst-class:: classref-method

:ref:`Array<class_Array>`\[:ref:`PhysicsBody2D<class_PhysicsBody2D>`\] **get_collision_exceptions**\ (\ ) :ref:`🔗<class_PhysicsBody2D_method_get_collision_exceptions>`

Returns an array of nodes that were added as collision exceptions for this body.

.. rst-class:: classref-item-separator

----

.. _class_PhysicsBody2D_method_get_gravity:

.. rst-class:: classref-method

:ref:`Vector2<class_Vector2>` **get_gravity**\ (\ ) |const| :ref:`🔗<class_PhysicsBody2D_method_get_gravity>`

Returns the gravity vector computed from all sources that can affect the body, including all gravity overrides from :ref:`Area2D<class_Area2D>` nodes and the global world gravity.

.. rst-class:: classref-item-separator

----

.. _class_PhysicsBody2D_method_move_and_collide:

.. rst-class:: classref-method

:ref:`KinematicCollision2D<class_KinematicCollision2D>` **move_and_collide**\ (\ motion\: :ref:`Vector2<class_Vector2>`, test_only\: :ref:`bool<class_bool>` = false, safe_margin\: :ref:`float<class_float>` = 0.08, recovery_as_collision\: :ref:`bool<class_bool>` = false\ ) :ref:`🔗<class_PhysicsBody2D_method_move_and_collide>`

Moves the body along the vector ``motion``. In order to be frame rate independent in :ref:`Node._physics_process<class_Node_private_method__physics_process>` or :ref:`Node._process<class_Node_private_method__process>`, ``motion`` should be computed using ``delta``.

Returns a :ref:`KinematicCollision2D<class_KinematicCollision2D>`, which contains information about the collision when stopped, or when touching another body along the motion.

If ``test_only`` is ``true``, the body does not move but the would-be collision information is given.

\ ``safe_margin`` is the extra margin used for collision recovery (see :ref:`CharacterBody2D.safe_margin<class_CharacterBody2D_property_safe_margin>` for more details).

If ``recovery_as_collision`` is ``true``, any depenetration from the recovery phase is also reported as a collision; this is used e.g. by :ref:`CharacterBody2D<class_CharacterBody2D>` for improving floor detection during floor snapping.

.. rst-class:: classref-item-separator

----

.. _class_PhysicsBody2D_method_remove_collision_exception_with:

.. rst-class:: classref-method

|void| **remove_collision_exception_with**\ (\ body\: :ref:`Node<class_Node>`\ ) :ref:`🔗<class_PhysicsBody2D_method_remove_collision_exception_with>`

Removes a body from the list of bodies that this body can't collide with.

.. rst-class:: classref-item-separator

----

.. _class_PhysicsBody2D_method_test_move:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **test_move**\ (\ from\: :ref:`Transform2D<class_Transform2D>`, motion\: :ref:`Vector2<class_Vector2>`, collision\: :ref:`KinematicCollision2D<class_KinematicCollision2D>` = null, safe_margin\: :ref:`float<class_float>` = 0.08, recovery_as_collision\: :ref:`bool<class_bool>` = false\ ) :ref:`🔗<class_PhysicsBody2D_method_test_move>`

Checks for collisions without moving the body. In order to be frame rate independent in :ref:`Node._physics_process<class_Node_private_method__physics_process>` or :ref:`Node._process<class_Node_private_method__process>`, ``motion`` should be computed using ``delta``.

Virtually sets the node's position, scale and rotation to that of the given :ref:`Transform2D<class_Transform2D>`, then tries to move the body along the vector ``motion``. Returns ``true`` if a collision would stop the body from moving along the whole path.

\ ``collision`` is an optional object of type :ref:`KinematicCollision2D<class_KinematicCollision2D>`, which contains additional information about the collision when stopped, or when touching another body along the motion.

\ ``safe_margin`` is the extra margin used for collision recovery (see :ref:`CharacterBody2D.safe_margin<class_CharacterBody2D_property_safe_margin>` for more details).

If ``recovery_as_collision`` is ``true``, any depenetration from the recovery phase is also reported as a collision; this is useful for checking whether the body would *touch* any other bodies.
