<description>
Duplicates the node, returning a new node with all of its properties, signals, groups, and children copied from the original. The behavior can be tweaked through the [param flags] (see [enum DuplicateFlags]). Internal nodes are not duplicated.
[b]Note:[/b] For nodes with a [Script] attached, if [method Object._init] has been defined with required parameters, the duplicated node will not have a [Script].
[b]Note:[/b] By default, this method will duplicate only properties marked for serialization (i.e. using [constant @GlobalScope.PROPERTY_USAGE_STORAGE], or in GDScript, [annotation @GDScript.@export]). If you want to duplicate all properties, use [constant DUPLICATE_INTERNAL_STATE].
