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

.. _class_Physics2DDirectSpaceState_method_cast_motion:

- :ref:`Array<class_Array>` **cast_motion** **(** :ref:`Physics2DShapeQueryParameters<class_Physics2DShapeQueryParameters>` shape **)**

Checks how far the shape can travel toward a point. If the shape can not move, the array will be empty.

**Note:** Both the shape and the motion are supplied through a :ref:`Physics2DShapeQueryParameters<class_Physics2DShapeQueryParameters>` object. The method will return an array with two floats between 0 and 1, both representing a fraction of ``motion``. The first is how far the shape can move without triggering a collision, and the second is the point at which a collision will occur. If no collision is detected, the returned array will be ``[1, 1]``.

----

.. _class_Physics2DDirectSpaceState_method_collide_shape:

- :ref:`Array<class_Array>` **collide_shape** **(** :ref:`Physics2DShapeQueryParameters<class_Physics2DShapeQueryParameters>` shape, :ref:`int<class_int>` max_results=32 **)**

Checks the intersections of a shape, given through a :ref:`Physics2DShapeQueryParameters<class_Physics2DShapeQueryParameters>` object, against the space. The resulting array contains a list of points where the shape intersects another. Like with :ref:`intersect_shape<class_Physics2DDirectSpaceState_method_intersect_shape>`, the number of returned results can be limited to save processing time.

----

.. _class_Physics2DDirectSpaceState_method_get_rest_info:

- :ref:`Dictionary<class_Dictionary>` **get_rest_info** **(** :ref:`Physics2DShapeQueryParameters<class_Physics2DShapeQueryParameters>` shape **)**

Checks the intersections of a shape, given through a :ref:`Physics2DShapeQueryParameters<class_Physics2DShapeQueryParameters>` object, against the space. If it collides with more than one shape, the nearest one is selected. 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. 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:`Vector2<class_Vector2>`. If the object is an :ref:`Area2D<class_Area2D>`, the result is ``(0, 0)``.

``metadata``: The intersecting shape's metadata. This metadata is different from :ref:`Object.get_meta<class_Object_method_get_meta>`, and is set with :ref:`Physics2DServer.shape_set_data<class_Physics2DServer_method_shape_set_data>`.

``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.

----

.. _class_Physics2DDirectSpaceState_method_intersect_point:

- :ref:`Array<class_Array>` **intersect_point** **(** :ref:`Vector2<class_Vector2>` point, :ref:`int<class_int>` max_results=32, :ref:`Array<class_Array>` exclude=[  ], :ref:`int<class_int>` collision_layer=2147483647, :ref:`bool<class_bool>` collide_with_bodies=true, :ref:`bool<class_bool>` collide_with_areas=false **)**

Checks whether a point is inside any shape. 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.

``metadata``: The intersecting shape's metadata. This metadata is different from :ref:`Object.get_meta<class_Object_method_get_meta>`, and is set with :ref:`Physics2DServer.shape_set_data<class_Physics2DServer_method_shape_set_data>`.

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

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

Additionally, the method can take an ``exclude`` array of objects or :ref:`RID<class_RID>`\ s that are to be excluded from collisions, a ``collision_mask`` bitmask representing the physics layers to check in, or booleans to determine if the ray should collide with :ref:`PhysicsBody<class_PhysicsBody>`\ s or :ref:`Area<class_Area>`\ s, respectively.

----

.. _class_Physics2DDirectSpaceState_method_intersect_point_on_canvas:

- :ref:`Array<class_Array>` **intersect_point_on_canvas** **(** :ref:`Vector2<class_Vector2>` point, :ref:`int<class_int>` canvas_instance_id, :ref:`int<class_int>` max_results=32, :ref:`Array<class_Array>` exclude=[  ], :ref:`int<class_int>` collision_layer=2147483647, :ref:`bool<class_bool>` collide_with_bodies=true, :ref:`bool<class_bool>` collide_with_areas=false **)**

----

.. _class_Physics2DDirectSpaceState_method_intersect_ray:

- :ref:`Dictionary<class_Dictionary>` **intersect_ray** **(** :ref:`Vector2<class_Vector2>` from, :ref:`Vector2<class_Vector2>` to, :ref:`Array<class_Array>` exclude=[  ], :ref:`int<class_int>` collision_layer=2147483647, :ref:`bool<class_bool>` collide_with_bodies=true, :ref:`bool<class_bool>` collide_with_areas=false **)**

Intersects a ray in a given space. The returned object is a dictionary with the following fields:

``collider``: The colliding object.

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

``metadata``: The intersecting shape's metadata. This metadata is different from :ref:`Object.get_meta<class_Object_method_get_meta>`, and is set with :ref:`Physics2DServer.shape_set_data<class_Physics2DServer_method_shape_set_data>`.

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

``position``: The intersection point.

``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.

Additionally, the method can take an ``exclude`` array of objects or :ref:`RID<class_RID>`\ s that are to be excluded from collisions, a ``collision_mask`` bitmask representing the physics layers to check in, or booleans to determine if the ray should collide with :ref:`PhysicsBody<class_PhysicsBody>`\ s or :ref:`Area<class_Area>`\ s, respectively.

----

.. _class_Physics2DDirectSpaceState_method_intersect_shape:

- :ref:`Array<class_Array>` **intersect_shape** **(** :ref:`Physics2DShapeQueryParameters<class_Physics2DShapeQueryParameters>` shape, :ref:`int<class_int>` max_results=32 **)**

Checks the intersections of a shape, given through a :ref:`Physics2DShapeQueryParameters<class_Physics2DShapeQueryParameters>` object, against the space.

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

``metadata``: The intersecting shape's metadata. This metadata is different from :ref:`Object.get_meta<class_Object_method_get_meta>`, and is set with :ref:`Physics2DServer.shape_set_data<class_Physics2DServer_method_shape_set_data>`.

``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.
