.. _class_PhysicsTestMotionParameters2D_property_collide_separation_ray:
.. rst-class:: classref-property
:ref:`bool<class_bool>` **collide_separation_ray** = ``false`` :ref:`🔗<class_PhysicsTestMotionParameters2D_property_collide_separation_ray>`
.. rst-class:: classref-property-setget
- |void| **set_collide_separation_ray_enabled**\ (\ value\: :ref:`bool<class_bool>`\ )
- :ref:`bool<class_bool>` **is_collide_separation_ray_enabled**\ (\ )
If set to ``true``, shapes of type :ref:`PhysicsServer2D.SHAPE_SEPARATION_RAY<class_PhysicsServer2D_constant_SHAPE_SEPARATION_RAY>` are used to detect collisions and can stop the motion. Can be useful when snapping to the ground.
If set to ``false``, shapes of type :ref:`PhysicsServer2D.SHAPE_SEPARATION_RAY<class_PhysicsServer2D_constant_SHAPE_SEPARATION_RAY>` are only used for separation when overlapping with other bodies. That's the main use for separation ray shapes.

.. rst-class:: classref-property
:ref:`Array<class_Array>`\[:ref:`RID<class_RID>`\] **exclude_bodies** = ``[]`` :ref:`🔗<class_PhysicsTestMotionParameters2D_property_exclude_bodies>`

- :ref:`Array<class_Array>`\[:ref:`RID<class_RID>`\] **get_exclude_bodies**\ (\ )
Optional array of body :ref:`RID<class_RID>` to exclude from collision. Use :ref:`CollisionObject2D.get_rid<class_CollisionObject2D_method_get_rid>` to get the :ref:`RID<class_RID>` associated with a :ref:`CollisionObject2D<class_CollisionObject2D>`-derived node.

:ref:`Array<class_Array>`\[:ref:`int<class_int>`\] **exclude_objects** = ``[]`` :ref:`🔗<class_PhysicsTestMotionParameters2D_property_exclude_objects>`

- :ref:`Array<class_Array>`\[:ref:`int<class_int>`\] **get_exclude_objects**\ (\ )
Optional array of object unique instance ID to exclude from collision. See :ref:`Object.get_instance_id<class_Object_method_get_instance_id>`.

.. _class_PhysicsTestMotionParameters2D_property_from:
.. rst-class:: classref-property
:ref:`Transform2D<class_Transform2D>` **from** = ``Transform2D(1, 0, 0, 1, 0, 0)`` :ref:`🔗<class_PhysicsTestMotionParameters2D_property_from>`
.. rst-class:: classref-property-setget
- |void| **set_from**\ (\ value\: :ref:`Transform2D<class_Transform2D>`\ )
- :ref:`Transform2D<class_Transform2D>` **get_from**\ (\ )
Transform in global space where the motion should start. Usually set to :ref:`Node2D.global_transform<class_Node2D_property_global_transform>` for the current body's transform.

.. _class_PhysicsTestMotionParameters2D_property_margin:
.. rst-class:: classref-property
:ref:`float<class_float>` **margin** = ``0.08`` :ref:`🔗<class_PhysicsTestMotionParameters2D_property_margin>`
.. rst-class:: classref-property-setget
- |void| **set_margin**\ (\ value\: :ref:`float<class_float>`\ )
- :ref:`float<class_float>` **get_margin**\ (\ )
Increases the size of the shapes involved in the collision detection.

.. _class_PhysicsTestMotionParameters2D_property_motion:
.. rst-class:: classref-property
:ref:`Vector2<class_Vector2>` **motion** = ``Vector2(0, 0)`` :ref:`🔗<class_PhysicsTestMotionParameters2D_property_motion>`
.. rst-class:: classref-property-setget
- |void| **set_motion**\ (\ value\: :ref:`Vector2<class_Vector2>`\ )
- :ref:`Vector2<class_Vector2>` **get_motion**\ (\ )
Motion vector to define the length and direction of the motion to test.

.. _class_PhysicsTestMotionParameters2D_property_recovery_as_collision:
.. rst-class:: classref-property
:ref:`bool<class_bool>` **recovery_as_collision** = ``false`` :ref:`🔗<class_PhysicsTestMotionParameters2D_property_recovery_as_collision>`
.. rst-class:: classref-property-setget
- |void| **set_recovery_as_collision_enabled**\ (\ value\: :ref:`bool<class_bool>`\ )
- :ref:`bool<class_bool>` **is_recovery_as_collision_enabled**\ (\ )
If set to ``true``, any depenetration from the recovery phase is reported as a collision; this is used e.g. by :ref:`CharacterBody2D<class_CharacterBody2D>` for improving floor detection during floor snapping.
If set to ``false``, only collisions resulting from the motion are reported, which is generally the desired behavior.
