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

.. _class_PhysicsDirectSpaceState3D_method_cast_motion:

.. rst-class:: classref-method

:ref:`PackedFloat32Array<class_PackedFloat32Array>` **cast_motion**\ (\ parameters\: :ref:`PhysicsShapeQueryParameters3D<class_PhysicsShapeQueryParameters3D>`\ ) :ref:`🔗<class_PhysicsDirectSpaceState3D_method_cast_motion>`

Checks how far a :ref:`Shape3D<class_Shape3D>` can move without colliding. All the parameters for the query, including the shape, are supplied through a :ref:`PhysicsShapeQueryParameters3D<class_PhysicsShapeQueryParameters3D>` object.

Returns an array with the safe and unsafe proportions (between 0 and 1) of the motion. The safe proportion is the maximum fraction of the motion that can be made without a collision. The unsafe proportion is the minimum fraction of the distance that must be moved for a collision. If no collision is detected a result of ``[1.0, 1.0]`` will be returned.

\ **Note:** Any :ref:`Shape3D<class_Shape3D>`\ s that the shape is already colliding with e.g. inside of, will be ignored. Use :ref:`collide_shape<class_PhysicsDirectSpaceState3D_method_collide_shape>` to determine the :ref:`Shape3D<class_Shape3D>`\ s that the shape is already colliding with.

.. _class_PhysicsDirectSpaceState3D_method_collide_shape:

.. rst-class:: classref-method

:ref:`Array<class_Array>`\[:ref:`Vector3<class_Vector3>`\] **collide_shape**\ (\ parameters\: :ref:`PhysicsShapeQueryParameters3D<class_PhysicsShapeQueryParameters3D>`, max_results\: :ref:`int<class_int>` = 32\ ) :ref:`🔗<class_PhysicsDirectSpaceState3D_method_collide_shape>`

Checks the intersections of a shape, given through a :ref:`PhysicsShapeQueryParameters3D<class_PhysicsShapeQueryParameters3D>` object, against the space. The resulting array contains a list of points where the shape intersects another. Like with :ref:`intersect_shape<class_PhysicsDirectSpaceState3D_method_intersect_shape>`, the number of returned results can be limited to save processing time.

Returned points are a list of pairs of contact points. For each pair the first one is in the shape passed in :ref:`PhysicsShapeQueryParameters3D<class_PhysicsShapeQueryParameters3D>` object, second one is in the collided shape from the physics space.

\ **Note:** This method does not take into account the ``motion`` property of the object.

.. _class_PhysicsDirectSpaceState3D_method_get_rest_info:

.. rst-class:: classref-method

:ref:`Dictionary<class_Dictionary>` **get_rest_info**\ (\ parameters\: :ref:`PhysicsShapeQueryParameters3D<class_PhysicsShapeQueryParameters3D>`\ ) :ref:`🔗<class_PhysicsDirectSpaceState3D_method_get_rest_info>`

Checks the intersections of a shape, given through a :ref:`PhysicsShapeQueryParameters3D<class_PhysicsShapeQueryParameters3D>` object, against the space. If it collides with more than one shape, the nearest one is selected. The returned object is a dictionary containing the following fields:

\ ``collider_id``: The colliding object's ID.

\ ``linear_velocity``: The colliding object's velocity :ref:`Vector3<class_Vector3>`. If the object is an :ref:`Area3D<class_Area3D>`, the result is ``(0, 0, 0)``.

\ ``normal``: The object's surface normal at the intersection point.

\ ``point``: The intersection point.

\ ``rid``: The intersecting object's :ref:`RID<class_RID>`.

\ ``shape``: The shape index of the colliding shape.

If the shape did not intersect anything, then an empty dictionary is returned instead.

\ **Note:** This method does not take into account the ``motion`` property of the object.

.. _class_PhysicsDirectSpaceState3D_method_intersect_point:

.. rst-class:: classref-method

:ref:`Array<class_Array>`\[:ref:`Dictionary<class_Dictionary>`\] **intersect_point**\ (\ parameters\: :ref:`PhysicsPointQueryParameters3D<class_PhysicsPointQueryParameters3D>`, max_results\: :ref:`int<class_int>` = 32\ ) :ref:`🔗<class_PhysicsDirectSpaceState3D_method_intersect_point>`

Checks whether a point is inside any solid shape. Position and other parameters are defined through :ref:`PhysicsPointQueryParameters3D<class_PhysicsPointQueryParameters3D>`. The shapes the point is inside of are returned in an array containing dictionaries with the following fields:

\ ``collider``: The colliding object.

\ ``collider_id``: The colliding object's ID.

\ ``rid``: The intersecting object's :ref:`RID<class_RID>`.

\ ``shape``: The shape index of the colliding shape.

The number of intersections can be limited with the ``max_results`` parameter, to reduce the processing time.

.. _class_PhysicsDirectSpaceState3D_method_intersect_ray:

.. rst-class:: classref-method

:ref:`Dictionary<class_Dictionary>` **intersect_ray**\ (\ parameters\: :ref:`PhysicsRayQueryParameters3D<class_PhysicsRayQueryParameters3D>`\ ) :ref:`🔗<class_PhysicsDirectSpaceState3D_method_intersect_ray>`

Intersects a ray in a given space. Ray position and other parameters are defined through :ref:`PhysicsRayQueryParameters3D<class_PhysicsRayQueryParameters3D>`. The returned object is a dictionary with the following fields:

\ ``collider``: The colliding object.

\ ``collider_id``: The colliding object's ID.

\ ``normal``: The object's surface normal at the intersection point, or ``Vector3(0, 0, 0)`` if the ray starts inside the shape and :ref:`PhysicsRayQueryParameters3D.hit_from_inside<class_PhysicsRayQueryParameters3D_property_hit_from_inside>` is ``true``.

\ ``position``: The intersection point.

\ ``face_index``: The face index at the intersection point.

\ **Note:** Returns a valid number only if the intersected shape is a :ref:`ConcavePolygonShape3D<class_ConcavePolygonShape3D>`. Otherwise, ``-1`` is returned.

\ ``rid``: The intersecting object's :ref:`RID<class_RID>`.

\ ``shape``: The shape index of the colliding shape.

If the ray did not intersect anything, then an empty dictionary is returned instead.

Checks the intersections of a shape, given through a :ref:`PhysicsShapeQueryParameters3D<class_PhysicsShapeQueryParameters3D>` object, against the space. The intersected shapes are returned in an array containing dictionaries with the following fields:

\ ``collider``: The colliding object.

\ ``collider_id``: The colliding object's ID.

\ ``rid``: The intersecting object's :ref:`RID<class_RID>`.

\ ``shape``: The shape index of the colliding shape.

The number of intersections can be limited with the ``max_results`` parameter, to reduce the processing time.
