<class name="PackedScene" inherits="Resource" version="4.0">
<brief_description>
An abstraction of a serialized scene.
</brief_description>
<description>
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 nodes it owns get saved (see [code]owner[/code] property on [Node]).
[b]Note:[/b] The node doesn't need to own itself.
[b]Example of loading a saved scene:[/b]
[codeblocks]
[gdscript]
# Use load() instead of preload() if the path isn't known at compile-time.
var scene = preload("res://scene.tscn").instance()
# Add the node as a child of the node the script is attached to.
add_child(scene)
[/gdscript]
[csharp]
// C# has no preload, so you have to always use ResourceLoader.Load<PackedScene>().
var scene = ResourceLoader.Load<PackedScene>("res://scene.tscn").Instance();
// Add the node as a child of the node the script is attached to.
AddChild(scene);
[/csharp]
[/codeblocks]
[b]Example of saving a node with different owners:[/b] The following example creates 3 objects: [code]Node2D[/code] ([code]node[/code]), [code]RigidBody2D[/code] ([code]rigid[/code]) and [code]CollisionObject2D[/code] ([code]collision[/code]). [code]collision[/code] is a child of [code]rigid[/code] which is a child of [code]node[/code]. Only [code]rigid[/code] is owned by [code]node[/code] and [code]pack[/code] will therefore only save those two nodes, but not [code]collision[/code].
[codeblocks]
[gdscript]
# Create the objects.
var node = Node2D.new()
var rigid = RigidBody2D.new()
var collision = CollisionShape2D.new()
# Create the object hierarchy.
rigid.add_child(collision)
node.add_child(rigid)
# Change owner of `rigid`, but not of `collision`.
rigid.owner = node
var scene = PackedScene.new()
# Only `node` and `rigid` are now packed.
var result = scene.pack(node)
if result == OK:
var error = ResourceSaver.save("res://path/name.tscn", scene) # Or "user://..."
if error != OK:
push_error("An error occurred while saving the scene to disk.")
[/gdscript]
[csharp]
// Create the objects.
var node = new Node2D();
var rigid = new RigidBody2D();
var collision = new CollisionShape2D();
// Create the object hierarchy.
rigid.AddChild(collision);
node.AddChild(rigid);
// Change owner of `rigid`, but not of `collision`.
rigid.Owner = node;
var scene = new PackedScene();
// Only `node` and `rigid` are now packed.
Error result = scene.Pack(node);
if (result == Error.Ok)
{
Error error = ResourceSaver.Save("res://path/name.tscn", scene); // Or "user://..."
if (error != Error.Ok)
{
GD.PushError("An error occurred while saving the scene to disk.");
}
}

<method name="get_state">
<return type="SceneState">
</return>
<description>
Returns the [code]SceneState[/code] representing the scene file contents.

<return type="Node">
</return>
<argument index="0" name="edit_state" type="int" enum="PackedScene.GenEditState" default="0">
</argument>
<description>
Instantiates the scene's node hierarchy. Triggers child scene instantiation(s). Triggers a [constant Node.NOTIFICATION_INSTANCED] notification on the root node.

<method name="pack">
<return type="int" enum="Error">

<description>
Pack will ignore any sub-nodes not owned by given node. See [member Node.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.
