Enumerations
------------

.. _enum_CollisionPolygon2D_BuildMode:

.. _class_CollisionPolygon2D_constant_BUILD_SOLIDS:

.. _class_CollisionPolygon2D_constant_BUILD_SEGMENTS:

enum **BuildMode**:

- **BUILD_SOLIDS** = **0** --- Collisions will include the polygon and its contained area.

- **BUILD_SEGMENTS** = **1** --- Collisions will only include the polygon edges.

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

Provides a 2D collision polygon to a :ref:`CollisionObject2D<class_CollisionObject2D>` parent. Polygon can be drawn in the editor or specified by a list of vertices.

Property Descriptions
---------------------

.. _class_CollisionPolygon2D_property_build_mode:

- :ref:`BuildMode<enum_CollisionPolygon2D_BuildMode>` **build_mode**

+----------+-----------------------+
| *Setter* | set_build_mode(value) |
+----------+-----------------------+
| *Getter* | get_build_mode()      |
+----------+-----------------------+

Collision build mode. Use one of the ``BUILD_*`` constants. Default value: :ref:`BUILD_SOLIDS<class_CollisionPolygon2D_constant_BUILD_SOLIDS>`.

----

.. _class_CollisionPolygon2D_property_disabled:

- :ref:`bool<class_bool>` **disabled**

+----------+---------------------+
| *Setter* | set_disabled(value) |
+----------+---------------------+
| *Getter* | is_disabled()       |
+----------+---------------------+

If ``true``, no collisions will be detected.

----

.. _class_CollisionPolygon2D_property_one_way_collision:

- :ref:`bool<class_bool>` **one_way_collision**

+----------+--------------------------------+
| *Setter* | set_one_way_collision(value)   |
+----------+--------------------------------+
| *Getter* | is_one_way_collision_enabled() |
+----------+--------------------------------+

If ``true``, only edges that face up, relative to CollisionPolygon2D's rotation, will collide with other objects.

----

.. _class_CollisionPolygon2D_property_one_way_collision_margin:

- :ref:`float<class_float>` **one_way_collision_margin**

+----------+-------------------------------------+
| *Setter* | set_one_way_collision_margin(value) |
+----------+-------------------------------------+
| *Getter* | get_one_way_collision_margin()      |
+----------+-------------------------------------+

----

.. _class_CollisionPolygon2D_property_polygon:

- :ref:`PoolVector2Array<class_PoolVector2Array>` **polygon**

+----------+--------------------+
| *Setter* | set_polygon(value) |
+----------+--------------------+
| *Getter* | get_polygon()      |
+----------+--------------------+

The polygon's list of vertices. The final point will be connected to the first. The returned value is a clone of the PoolVector2Array, not a reference.
