A node that provides a thickened polygon shape (a prism) to a [CollisionObject3D] parent. A node that provides a thickened polygon shape (a prism) to a [CollisionObject3D] parent and allows to edit it. The polygon can be concave or convex. This can give a detection shape to an [Area3D] or turn [PhysicsBody3D] into a solid object. [b]Warning:[/b] A non-uniformly scaled [CollisionShape3D] will likely not behave as expected. Make sure to keep its scale the same on all axes and adjust its shape resource instead. Length that the resulting collision extends in either direction perpendicular to its 2D polygon. If [code]true[/code], no collision will be produced. The collision margin for the generated [Shape3D]. See [member Shape3D.margin] for more details. Array of vertices which define the 2D polygon in the local XY plane.
