Description
-----------
**PhysicsBody3D** is an abstract base class for 3D game objects affected by physics. All 3D physics bodies inherit from it.
\ **Warning:** With a non-uniform scale, this node will likely not behave as expected. It is advised to keep its scale the same on all axes and adjust its collision shape(s) instead.

.. rst-class:: classref-method
|void| **add_collision_exception_with**\ (\ body\: :ref:`Node<class_Node>`\ ) :ref:`🔗<class_PhysicsBody3D_method_add_collision_exception_with>`

:ref:`bool<class_bool>` **get_axis_lock**\ (\ axis\: :ref:`BodyAxis<enum_PhysicsServer3D_BodyAxis>`\ ) |const| :ref:`🔗<class_PhysicsBody3D_method_get_axis_lock>`
Returns ``true`` if the specified linear or rotational ``axis`` is locked.
.. rst-class:: classref-item-separator
----
.. _class_PhysicsBody3D_method_get_collision_exceptions:
.. rst-class:: classref-method
:ref:`Array<class_Array>`\[:ref:`PhysicsBody3D<class_PhysicsBody3D>`\] **get_collision_exceptions**\ (\ ) :ref:`🔗<class_PhysicsBody3D_method_get_collision_exceptions>`
Returns an array of nodes that were added as collision exceptions for this body.

----
.. _class_PhysicsBody3D_method_get_gravity:
.. rst-class:: classref-method
:ref:`Vector3<class_Vector3>` **get_gravity**\ (\ ) |const| :ref:`🔗<class_PhysicsBody3D_method_get_gravity>`
Returns the gravity vector computed from all sources that can affect the body, including all gravity overrides from :ref:`Area3D<class_Area3D>` nodes and the global world gravity.
.. rst-class:: classref-item-separator
----
.. _class_PhysicsBody3D_method_move_and_collide:
.. rst-class:: classref-method
:ref:`KinematicCollision3D<class_KinematicCollision3D>` **move_and_collide**\ (\ motion\: :ref:`Vector3<class_Vector3>`, test_only\: :ref:`bool<class_bool>` = false, safe_margin\: :ref:`float<class_float>` = 0.001, recovery_as_collision\: :ref:`bool<class_bool>` = false, max_collisions\: :ref:`int<class_int>` = 1\ ) :ref:`🔗<class_PhysicsBody3D_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``.
The body will stop if it collides. Returns a :ref:`KinematicCollision3D<class_KinematicCollision3D>`, 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:`CharacterBody3D.safe_margin<class_CharacterBody3D_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:`CharacterBody3D<class_CharacterBody3D>` for improving floor detection during floor snapping.
\ ``max_collisions`` allows to retrieve more than one collision result.

.. rst-class:: classref-method
|void| **remove_collision_exception_with**\ (\ body\: :ref:`Node<class_Node>`\ ) :ref:`🔗<class_PhysicsBody3D_method_remove_collision_exception_with>`
Removes a body from the list of bodies that this body can't collide with.

|void| **set_axis_lock**\ (\ axis\: :ref:`BodyAxis<enum_PhysicsServer3D_BodyAxis>`, lock\: :ref:`bool<class_bool>`\ ) :ref:`🔗<class_PhysicsBody3D_method_set_axis_lock>`
Locks or unlocks the specified linear or rotational ``axis`` depending on the value of ``lock``.
.. rst-class:: classref-item-separator
----
.. _class_PhysicsBody3D_method_test_move:
.. rst-class:: classref-method

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:`Transform3D<class_Transform3D>`, 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:`KinematicCollision3D<class_KinematicCollision3D>`, 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:`CharacterBody3D.safe_margin<class_CharacterBody3D_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.
\ ``max_collisions`` allows to retrieve more than one collision result.
