Brief Description

An abstraction of a serialized scene.

Properties

Dictionary _bundled {“conn_count”: 0,”conns”: PoolIntArray( ),”editable_instances”: [ ],”names”: PoolStringArray( ),”node_count”: 0,”node_paths”: [ ],”nodes”: PoolIntArray( ),”variants”: [ ],”version”: 2}

Methods

bool can_instance ( ) const
SceneState get_state ( )
Node instance ( GenEditState edit_state=0 ) const
Error pack ( Node path )

Enumerations

enum GenEditState:

  • GEN_EDIT_STATE_DISABLED = 0 — If passed to instance, blocks edits to the scene state.
  • GEN_EDIT_STATE_INSTANCE = 1 — If passed to instance, provides local scene resources to the local scene.

Note: Only available in editor builds.

  • GEN_EDIT_STATE_MAIN = 2 — If passed to instance, provides local scene resources to the local scene. Only the main scene should receive the main edit state.

Note: Only available in editor builds.

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 node it owns get saved (see owner property on Node).

Note: The node doesn’t need to own itself.

Example of saving a node with different owners: The following example creates 3 objects: Node2D (node), RigidBody2D (rigid) and CollisionObject2D (collision). collision is a child of rigid which is a child of node. Only rigid is owned by node and pack will therefore only save those two nodes, but not collision.

# 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:
    ResourceSaver.save("res://path/name.scn", scene) # Or "user://..."

Property Descriptions

Default {“conn_count”: 0,”conns”: PoolIntArray( ),”editable_instances”: [ ],”names”: PoolStringArray( ),”node_count”: 0,”node_paths”: [ ],”nodes”: PoolIntArray( ),”variants”: [ ],”version”: 2}

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.

Method Descriptions

  • bool can_instance ( ) const

Returns true if the scene file has nodes.


Returns the SceneState representing the scene file contents.


Instantiates the scene’s node hierarchy. Triggers child scene instantiation(s). Triggers a Node.NOTIFICATION_INSTANCED notification on the root node.


Pack will ignore any sub-nodes not owned by given node. See Node.owner.
