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. The collision shape color that is displayed in the editor, or in the running project if [b]Debug > Visible Collision Shapes[/b] is checked at the top of the editor. [b]Note:[/b] The default value is [member ProjectSettings.debug/shapes/collision/shape_color]. The [code]Color(0, 0, 0, 0)[/code] value documented here is a placeholder, and not the actual default debug color. If [code]true[/code], when the shape is displayed, it will show a solid fill color in addition to its wireframe. 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.
