Polygon2D
=========
**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.
