A simplified interface to a scene file. Provides access to operations and checks that can be performed on the scene resource itself.
2019-06-22 01:04:47 +02:00
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]).
[b]Note:[/b] The node doesn't need to own itself.
2020-07-09 20:05:33 +02:00
[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]
2019-06-22 01:04:47 +02:00
[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].

var node = Node2D.new()

var collision = CollisionShape2D.new()

# Change owner of `rigid`, but not of `collision`.
