<description>
Adds a child node. Nodes can have any number of children, but every child must have a unique name. Child nodes are automatically deleted when the parent node is deleted, so an entire scene can be removed by deleting its topmost node.
If [code]legible_unique_name[/code] is [code]true[/code], the child node will have an human-readable name based on the name of the node being instanced instead of its type.
[b]Note:[/b] If the child node already has a parent, the function will fail. Use [method remove_child] first to remove the node from its current parent. For example:
[codeblock]
if child_node.get_parent():
child_node.get_parent().remove_child(child_node)
add_child(child_node)
[/codeblock]
