Member Variables
----------------

- :ref:`int<class_int>` **light_mask** - The LightOccluder2D's light mask. The LightOccluder2D will cast shadows only from Light2D(s) that have the same light mask(s).
- :ref:`OccluderPolygon2D<class_occluderpolygon2d>` **occluder** - The [OccluderPolygon2D] used to compute the shadow.

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

Occludes light cast by a Light2D, casting shadows. The LightOccluder2D must be provided with an :ref:`OccluderPolygon2D<class_occluderpolygon2d>` in order for the shadow to be computed.

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

.. _class_LightOccluder2D_get_occluder_light_mask:

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

Return the light mask of the LightOccluder2D.

.. _class_LightOccluder2D_get_occluder_polygon:

- :ref:`OccluderPolygon2D<class_occluderpolygon2d>`  **get_occluder_polygon**  **(** **)** const

Return the OccluderPolygon2D that defines the LightOccluder2D.

.. _class_LightOccluder2D_set_occluder_light_mask:

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

Set the LightOccluder2D light mask. The LightOccluder2D will cast shadows only from Light2Ds that belong to the same light mask(s).

.. _class_LightOccluder2D_set_occluder_polygon:

- void  **set_occluder_polygon**  **(** :ref:`OccluderPolygon2D<class_occluderpolygon2d>` polygon  **)**

Set the OccluderPolygon2D that defines the LightOccluder2D.
