PackedScene

Inherits: Resource < Reference < Object Inherited By: PackedSceneGLTF An abstraction of a serialized scene.

Description

A simplified interface to a scene file. Provides access to operations and checks that can be performed on the scene resource itself. owner property on Node). Note: The node doesn’t need to own itself. Example of loading a saved scene:

  1. # 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)

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.

  1. # 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 = nodevar 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.scn", scene)  # Or "user://..."    if error != OK:        push_error("An error occurred while saving the scene to disk.")

    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.
  • GEN_EDIT_STATE_MAIN_INHERITED = 3 —- It’s similar to GEN_EDIT_STATE_MAIN, but for the case where the scene is being instantiated to be the base of another one. Note: Only available in editor builds.

    Property Descriptions

  • Dictionary _bundled 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 true if the scene file has nodes.
  • SceneState get_state ( ) SceneState representing the scene file contents.
  • Node instance ( GenEditState edit_state=0 ) const Node.NOTIFICATION_INSTANCED notification on the root node.
  • Error pack ( Node path ) Node.owner.
