Server interface for low-level physics access. PhysicsServer3D is the server responsible for all 3D physics. It can create many kinds of physics objects, but does not insert them on the node tree. Adds a shape to the area, along with a transform matrix. Shapes are usually referenced by their index, so you should track which shape has a given index. Assigns the area to a descendant of [Object], so it can exist in the node tree. Removes all shapes from an area. It does not delete the shapes, so they can be reassigned later. Creates an [Area3D].
