Automatically replicates spawnable nodes from the authority to other multiplayer peers. 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 [member spawn_function] 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. 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]. Clears all spawnable scenes. Does not despawn existing instances on remote peers. Returns the spawnable scene path by index. Returns the count of spawnable scene paths. Requests a custom spawn, with [param data] passed to [member spawn_function] 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. Method called on all peers when a custom [method spawn] is requested by the authority. Will receive the [code]data[/code] parameter, and should return a [Node] that is not in the scene tree. [b]Note:[/b] The returned node should [b]not[/b] be added to the scene with [method Node.add_child]. This is done automatically. Maximum number of nodes allowed to be spawned by this spawner. Includes both spawnable scenes and custom spawns. When set to [code]0[/code] (the default), there is no limit. Path to the spawn root. Spawnable scenes that are added as direct children are replicated to other peers. Emitted when a spawnable scene or custom spawn was despawned by the multiplayer authority. Only called on remote peers. Emitted when a spawnable scene or custom spawn was spawned by the multiplayer authority. Only called on remote peers.
