Concave polygon shape. Concave polygon shape resource, which can be set into a [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 [PhysicsBody] nodes like [StaticBody] and will not work with [KinematicBody] or [RigidBody] with a mode other than Static. Returns the faces (an array of triangles). Sets the faces (an array of triangles).
