ConcavePolygonShape
===================

**Inherits:** :ref:`Shape<class_Shape>` **<** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

Concave polygon shape.

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

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

Concave polygon shape resource, which can be set into a :ref:`PhysicsBody<class_PhysicsBody>` or area. This shape is created by feeding a list of triangles.

\ **Note:** When used for collision, **ConcavePolygonShape** is intended to work with static :ref:`PhysicsBody<class_PhysicsBody>` nodes like :ref:`StaticBody<class_StaticBody>` and will not work with :ref:`KinematicBody<class_KinematicBody>` or :ref:`RigidBody<class_RigidBody>` with a mode other than Static.

\ **Warning:** Using this shape for an :ref:`Area<class_Area>` (via a :ref:`CollisionShape<class_CollisionShape>` node, created e.g. by using the *Create Trimesh Collision Sibling* option in the *Mesh* menu that appears when selecting a :ref:`MeshInstance<class_MeshInstance>` node) may give unexpected results: when using Godot Physics, the area will only detect collisions with the triangle faces in the **ConcavePolygonShape** (and not with any "inside" of the shape, for example), and when using Bullet Physics the area will not detect any collisions with the concave shape at all (this is a known bug).
