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.
