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

.. _class_PhysicsBody2D_method_add_collision_exception_with:

.. rst-class:: classref-method

void **add_collision_exception_with** **(** :ref:`Node<class_Node>` body **)**

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:`PhysicsBody2D[]<class_PhysicsBody2D>` **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_move_and_collide:

.. rst-class:: classref-method

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

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** **(** :ref:`Node<class_Node>` body **)**

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

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.
