This function returns the root node of the element tree, called root. This node contains every other element: all resource root elements, players and remote clients. It is never destroyed and cannot be destroyed using destroyElement.

Note

All resources have a predefined global variable called root that has the root element as value. The variable exists server side as well as client side.
