	<brief_description>
		Automatically replicates spawnable nodes from the authority to other multiplayer peers.
	</brief_description>
	<description>
		Spawnable scenes can be configured in the editor or through code (see [method add_spawnable_scene]).
		Also supports custom node spawns through [method spawn], calling [method _spawn_custom] on all peers.
		Internally, [MultiplayerSpawner] uses [method MultiplayerAPI.object_configuration_add] to notify spawns passing the spawned node as the [code]object[/code] and itself as the [code]configuration[/code], and [method MultiplayerAPI.object_configuration_remove] to notify despawns in a similar way.

	<methods>
		<method name="_spawn_custom" qualifiers="virtual">
			<return type="Node" />
			<param index="0" name="data" type="Variant" />
			<description>
				Method called on all peers when a custom spawn was requested by the authority using [method spawn]. Should return a [Node] that is not in the scene tree.
				[b]Note:[/b] Spawned nodes should [b]not[/b] be added to the scene with [method Node.add_child]. This is done automatically.
			</description>
		</method>
		<method name="add_spawnable_scene">
			<return type="void" />
			<param index="0" name="path" type="String" />
			<description>
				Adds a scene path to spawnable scenes, making it automatically replicated from the multiplayer authority to other peers when added as children of the node pointed by [member spawn_path].
			</description>
		</method>
		<method name="clear_spawnable_scenes">
			<return type="void" />
			<description>
				Clears all spawnable scenes. Does not despawn existing instances on remote peers.
			</description>
		</method>
		<method name="get_spawnable_scene" qualifiers="const">
			<return type="String" />
			<param index="0" name="index" type="int" />
			<description>
				Returns the spawnable scene path by index.
			</description>
		</method>
		<method name="get_spawnable_scene_count" qualifiers="const">
			<return type="int" />
			<description>
				Returns the count of spawnable scene paths.
			</description>
		</method>
		<method name="spawn">
			<return type="Node" />
			<param index="0" name="data" type="Variant" default="null" />
			<description>
				Requests a custom spawn, with [code]data[/code] passed to [method _spawn_custom] on all peers. Returns the locally spawned node instance already inside the scene tree, and added as a child of the node pointed by [member spawn_path].
				[b]Note:[/b] Spawnable scenes are spawned automatically. [method spawn] is only needed for custom spawns.
