Configuration for properties to synchronize with a [MultiplayerSynchronizer]. Adds the property identified by the given [param path] to the list of the properties being synchronized, optionally passing an [param index]. [b]Note:[/b] For details on restrictions and limitations on property synchronization, see [MultiplayerSynchronizer]. Returns a list of synchronized property [NodePath]s. Returns [code]true[/code] if the given [param path] is configured for synchronization. Finds the index of the given [param path]. Returns the replication mode for the property identified by the given [param path]. See [enum ReplicationMode]. Returns [code]true[/code] if the property identified by the given [param path] is configured to be synchronized on spawn. Returns [code]true[/code] if the property identified by the given [param path] is configured to be synchronized on process. Returns [code]true[/code] if the property identified by the given [param path] is configured to be reliably synchronized when changes are detected on process. Sets the synchronization mode for the property identified by the given [param path]. See [enum ReplicationMode]. Sets whether the property identified by the given [param path] is configured to be synchronized on spawn. Sets whether the property identified by the given [param path] is configured to be synchronized on process. Sets whether the property identified by the given [param path] is configured to be reliably synchronized when changes are detected on process. Removes the property identified by the given [param path] from the configuration. Do not keep the given property synchronized. Replicate the given property on process by constantly sending updates using unreliable transfer mode. Replicate the given property on process by sending updates using reliable transfer mode when its value changes.
