CollisionPolygon2D
==================

**Inherits:** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

Defines a 2D collision polygon.

.. rst-class:: classref-introduction-group

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

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

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

.. _enum_CollisionPolygon2D_BuildMode:

.. rst-class:: classref-enumeration

enum **BuildMode**:

.. _class_CollisionPolygon2D_constant_BUILD_SOLIDS:

.. rst-class:: classref-enumeration-constant

:ref:`BuildMode<enum_CollisionPolygon2D_BuildMode>` **BUILD_SOLIDS** = ``0``

Collisions will include the polygon and its contained area.

.. _class_CollisionPolygon2D_constant_BUILD_SEGMENTS:

.. rst-class:: classref-enumeration-constant

:ref:`BuildMode<enum_CollisionPolygon2D_BuildMode>` **BUILD_SEGMENTS** = ``1``

Collisions will only include the polygon edges.

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

.. _class_CollisionPolygon2D_property_build_mode:

.. rst-class:: classref-property

:ref:`BuildMode<enum_CollisionPolygon2D_BuildMode>` **build_mode** = ``0``

.. rst-class:: classref-property-setget

- void **set_build_mode** **(** :ref:`BuildMode<enum_CollisionPolygon2D_BuildMode>` value **)**
- :ref:`BuildMode<enum_CollisionPolygon2D_BuildMode>` **get_build_mode** **(** **)**

Collision build mode. Use one of the :ref:`BuildMode<enum_CollisionPolygon2D_BuildMode>` constants.

.. rst-class:: classref-item-separator

----

.. _class_CollisionPolygon2D_property_disabled:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **disabled** = ``false``

.. rst-class:: classref-property-setget

- void **set_disabled** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_disabled** **(** **)**

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

.. rst-class:: classref-item-separator

----

.. _class_CollisionPolygon2D_property_one_way_collision:

.. rst-class:: classref-property

:ref:`bool<class_bool>` **one_way_collision** = ``false``

.. rst-class:: classref-property-setget

- void **set_one_way_collision** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_one_way_collision_enabled** **(** **)**

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

\ **Note:** This property has no effect if this **CollisionPolygon2D** is a child of an :ref:`Area2D<class_Area2D>` node.

.. rst-class:: classref-item-separator

----

.. _class_CollisionPolygon2D_property_one_way_collision_margin:

.. rst-class:: classref-property

:ref:`float<class_float>` **one_way_collision_margin** = ``1.0``

.. rst-class:: classref-property-setget

- void **set_one_way_collision_margin** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_one_way_collision_margin** **(** **)**

The margin used for one-way collision (in pixels). Higher values will make the shape thicker, and work better for colliders that enter the polygon at a high velocity.

.. rst-class:: classref-item-separator

----

.. _class_CollisionPolygon2D_property_polygon:

.. rst-class:: classref-property

:ref:`PoolVector2Array<class_PoolVector2Array>` **polygon** = ``PoolVector2Array(  )``

.. rst-class:: classref-property-setget

- void **set_polygon** **(** :ref:`PoolVector2Array<class_PoolVector2Array>` value **)**
- :ref:`PoolVector2Array<class_PoolVector2Array>` **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 :ref:`PoolVector2Array<class_PoolVector2Array>`, not a reference.
