Automatically replicates spawnable nodes from the authority to other multiplayer peers.

</brief_description>
|

<description>
|

This node 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.
|
||||
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.

Synchronizes properties from the multiplayer authority to the remote peers.
|

</brief_description>
|
||||
<description>
|
||||
The [MultiplayerSynchronizer] uses [method MultiplayerAPI.object_configuration_add] to notify synchronization start passing the [Node] at [member root_path] as the [code]object[/code] and itself as the [code]configuration[/code], and uses [method MultiplayerAPI.object_configuration_remove] to notify synchronization end in a similar way.
|
||||
By default, [MultiplayerSynchronizer] synchronizes configured properties to all peers.
|
||||
Visiblity can be handled directly with [method set_visibility_for] or as-needed with [method add_visibility_filter] and [method update_visibility].
|
||||
|
||||
[MultiplayerSpawner]s will handle nodes according to visibility of synchronizers as long as the node at [member root_path] was spawned by one.

||||
Internally, [MultiplayerSynchronizer] uses [method MultiplayerAPI.object_configuration_add] to notify synchronization start passing the [Node] at [member root_path] as the [code]object[/code] and itself as the [code]configuration[/code], and uses [method MultiplayerAPI.object_configuration_remove] to notify synchronization end in a similar way.
