Description
-----------

A RayCast2D represents a line from its origin to its destination position ``cast_to``, it is used to query the 2D space in order to find the closest object intersecting with the ray.

Member Function Description
---------------------------

.. _class_RayCast2D_set_enabled:

- void  **set_enabled**  **(** :ref:`bool<class_bool>` enabled  **)**

Enables the RayCast2D. Only enabled raycasts will be able to query the space and report collisions.

.. _class_RayCast2D_is_enabled:

- :ref:`bool<class_bool>`  **is_enabled**  **(** **)** const

Returns whether this raycast is enabled or not

.. _class_RayCast2D_set_cast_to:

- void  **set_cast_to**  **(** :ref:`Vector2<class_vector2>` local_point  **)**

Sets the ray destination point, so that the ray will test from the ray's origin to ``local_point``

.. _class_RayCast2D_get_cast_to:

- :ref:`Vector2<class_vector2>`  **get_cast_to**  **(** **)** const

Return the destination point of this ray object

.. _class_RayCast2D_is_colliding:

- :ref:`bool<class_bool>`  **is_colliding**  **(** **)** const

Return whether the closest object the ray is pointing to is colliding with the vector (considering the vector length).

.. _class_RayCast2D_get_collider:

- :ref:`Object<class_object>`  **get_collider**  **(** **)** const

Return the closest object the ray is pointing to. Note that this does not consider the length of the vector, so you must also use :ref:`is_colliding<class_RayCast2D_is_colliding>` to check if the object returned is actually colliding with the ray.

.. _class_RayCast2D_get_collider_shape:

- :ref:`int<class_int>`  **get_collider_shape**  **(** **)** const

Returns the collision shape of the closest object the ray is pointing to.

.. _class_RayCast2D_get_collision_point:

- :ref:`Vector2<class_vector2>`  **get_collision_point**  **(** **)** const

Returns the collision point in which the ray intersects the closest object.

.. _class_RayCast2D_get_collision_normal:

- :ref:`Vector2<class_vector2>`  **get_collision_normal**  **(** **)** const

Returns the normal of the intersecting object shape face containing the collision point.

.. _class_RayCast2D_add_exception_rid:

- void  **add_exception_rid**  **(** :ref:`RID<class_rid>` rid  **)**

.. _class_RayCast2D_add_exception:

- void  **add_exception**  **(** :ref:`Object<class_object>` node  **)**

Adds a collision exception so the ray does not report collisions with the specified ``node``.

.. _class_RayCast2D_remove_exception_rid:

- void  **remove_exception_rid**  **(** :ref:`RID<class_rid>` rid  **)**

.. _class_RayCast2D_remove_exception:

- void  **remove_exception**  **(** :ref:`Object<class_object>` node  **)**

Removes a collision exception so the ray does report collisions with the specified ``node``.

.. _class_RayCast2D_clear_exceptions:

- void  **clear_exceptions**  **(** **)**

Removes all collision exception for this ray.

.. _class_RayCast2D_set_layer_mask:

- void  **set_layer_mask**  **(** :ref:`int<class_int>` mask  **)**

.. _class_RayCast2D_get_layer_mask:

- :ref:`int<class_int>`  **get_layer_mask**  **(** **)** const

Returns the layer mask for this ray.

.. _class_RayCast2D_set_type_mask:

- void  **set_type_mask**  **(** :ref:`int<class_int>` mask  **)**

.. _class_RayCast2D_get_type_mask:

- :ref:`int<class_int>`  **get_type_mask**  **(** **)** const
