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 whether 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 whether the property identified by the given [param path] is configured to be synchronized on spawn. Returns whether the property identified by the given [param path] is configured to be synchronized on process. [i]Deprecated.[/i] Use [method property_get_replication_mode] instead. Returns whether the property identified by the given [param path] is configured to be reliably synchronized when changes are detected on process. [i]Deprecated.[/i] Use [method property_get_replication_mode] instead. 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. [i]Deprecated.[/i] Use [method property_set_replication_mode] with [constant REPLICATION_MODE_ALWAYS] instead. Sets whether the property identified by the given [param path] is configured to be reliably synchronized when changes are detected on process. [i]Deprecated.[/i] Use [method property_set_replication_mode] with [constant REPLICATION_MODE_ON_CHANGE] instead. 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.
