This makes it easier to spot syntax errors when editing the class reference. The schema is referenced locally so validation can still work offline. Each class XML's schema conformance is also checked on GitHub Actions.

<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]
|
|
[codeblock]
|
|
# 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)
|
|
[/codeblock]
|
|
[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].
|
|
[codeblock]
|
|
# 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.scn", scene) # Or "user://..."
|
|
if error != OK:
|
|
push_error("An error occurred while saving the scene to disk.")
|
|

Instantiates the scene's node hierarchy. Triggers child scene instantiation(s). Triggers a [constant Node.NOTIFICATION_INSTANCED] notification on the root node.

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.

<constants>

<constant name="GEN_EDIT_STATE_DISABLED" value="0" enum="GenEditState">

If passed to [method instance], blocks edits to the scene state.

</constant>
|

<constant name="GEN_EDIT_STATE_INSTANCE" value="1" enum="GenEditState">
|
|
If passed to [method instance], provides local scene resources to the local scene.

</constant>
|
|
<constant name="GEN_EDIT_STATE_MAIN" value="2" enum="GenEditState">
|
|
If passed to [method instance], provides local scene resources to the local scene. Only the main scene should receive the main edit state.

</constant>
|

<constant name="GEN_EDIT_STATE_MAIN_INHERITED" value="3" enum="GenEditState">
|

It's similar to [constant GEN_EDIT_STATE_MAIN], but for the case where the scene is being instantiated to be the base of another one.
