An abstraction of a serialized scene. A simplified interface to a scene file. Provides access to operations and checks that can be performed on the scene resource itself. Can be used to save a node to a file. When saving, the node as well as all the node it owns get saved (see [code]owner[/code] property on [Node]). Note that the node doesn't need to own itself. Example of saving a node: [codeblock] var scene = PackedScene.new() var result = scene.pack(child) if result == OK: ResourceSaver.save("res://path/name.scn", scene) # or user://... [/codeblock] Returns [code]true[/code] if the scene file has nodes. Returns the [code]SceneState[/code] representing the scene file contents. Instantiates the scene's node hierarchy. Triggers child scene instantiation(s). Triggers the [enum Node.NOTIFICATION_INSTANCED] notification on the root node. Pack will ignore any sub-nodes not owned by given node. See [method Node.set_owner]. A dictionary representation of the scene contents. Available keys include "rnames" and "variants" for resources, "node_count", "nodes", "node_paths" for nodes, "editable_instances" for base scene children overrides, "conn_count" and "conns" for signal connections, and "version" for the format style of the PackedScene. If passed to [method instance], blocks edits to the scene state. If passed to [method instance], provides local scene resources to the local scene. Requires tools compiled. If passed to [method instance], provides local scene resources to the local scene. Only the main scene should receive the main edit state. Requires tools compiled.
