CollisionPolygon3D
==================

**Inherits:** :ref:`Node3D<class_Node3D>` **<** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

A node that provides a thickened polygon shape (a prism) to a :ref:`CollisionObject3D<class_CollisionObject3D>` parent.

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

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

A node that provides a thickened polygon shape (a prism) to a :ref:`CollisionObject3D<class_CollisionObject3D>` parent and allows to edit it. The polygon can be concave or convex. This can give a detection shape to an :ref:`Area3D<class_Area3D>` or turn :ref:`PhysicsBody3D<class_PhysicsBody3D>` into a solid object.

\ **Warning:** A non-uniformly scaled :ref:`CollisionShape3D<class_CollisionShape3D>` will likely not behave as expected. Make sure to keep its scale the same on all axes and adjust its shape resource instead.

.. _class_CollisionPolygon3D_property_polygon:

.. rst-class:: classref-property

:ref:`PackedVector2Array<class_PackedVector2Array>` **polygon** = ``PackedVector2Array()`` :ref:`🔗<class_CollisionPolygon3D_property_polygon>`
