Polygon2D
=========

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

A 2D polygon.

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:

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

+-----------+------------------------+
| *Default* | ``false``              |
+-----------+------------------------+
| *Setter*  | set_antialiased(value) |
+-----------+------------------------+
| *Getter*  | 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.

| *Setter*  | set_texture_offset(value) |
+-----------+---------------------------+
| *Getter*  | get_texture_offset()      |

+-----------+--------------------------+

Amount to multiply the ``uv`` coordinates when using a ``texture``. Larger values make the texture smaller, and vice versa.

----

.. _class_Polygon2D_property_uv:

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

+-----------+--------------------------+
| *Default* | ``PoolVector2Array(  )`` |
