Polygon2D
=========
**繼承：** :ref:`Node2D<class_Node2D>` **<** :ref:`CanvasItem<class_CanvasItem>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`
2D 多邊形。
.. rst-class:: classref-introduction-group
說明
----
Polygon2D 由一組點定義。每個點都連接到下一個點，最後一個點連接到第一個點，從而形成一個封閉的多邊形。Polygon2D 可以填充顏色（純色或漸變），也可以填充給定的紋理。
