=========
**Inherits:** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
A 2D polygon.
.. rst-class:: classref-introduction-group
Description
-----------
A Polygon2D is defined by a set of points. Each point is connected to the next, with the final point being connected to the first, resulting in a closed polygon. Polygon2Ds can be filled with color (solid or gradient) or filled with a given texture.
\ **Note:** By default, Godot can only draw up to 4,096 polygon points at a time. To increase this limit, open the Project Settings and increase :ref:`ProjectSettings.rendering/limits/buffers/canvas_polygon_buffer_size_kb<class_ProjectSettings_property_rendering/limits/buffers/canvas_polygon_buffer_size_kb>` and :ref:`ProjectSettings.rendering/limits/buffers/canvas_polygon_index_buffer_size_kb<class_ProjectSettings_property_rendering/limits/buffers/canvas_polygon_index_buffer_size_kb>`.

Property Descriptions
---------------------
.. _class_Polygon2D_property_antialiased:
.. rst-class:: classref-property
:ref:`bool<class_bool>` **antialiased** = ``false``
.. rst-class:: classref-property-setget
- void **set_antialiased** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **get_antialiased** **(** **)**
If ``true``, attempts to perform antialiasing for polygon edges by drawing a thin OpenGL smooth line on the edges.
\ **Note:** Due to how it works, built-in antialiasing will not look correct for translucent polygons and may not work on certain platforms. As a workaround, install the `Antialiased Line2D <https://github.com/godot-extended-libraries/godot-antialiased-line2d>`__ add-on then create an AntialiasedPolygon2D node. That node relies on a texture with custom mipmaps to perform antialiasing.

The list of polygons, in case more than one is being represented. Every individual polygon is stored as a :ref:`PoolIntArray<class_PoolIntArray>` where each :ref:`int<class_int>` is an index to a point in :ref:`polygon<class_Polygon2D_property_polygon>`. If empty, this property will be ignored, and the resulting single polygon will be composed of all points in :ref:`polygon<class_Polygon2D_property_polygon>`, using the order they are stored in.
