MultiplayerSynchronizer

Inherits: Node < Object

Synchronizes properties from the multiplayer authority to the remote peers.

Description

By default, MultiplayerSynchronizer synchronizes configured properties to all peers.

Visibility can be handled directly with set_visibility_for or as-needed with add_visibility_filter and update_visibility.

MultiplayerSpawners will handle nodes according to visibility of synchronizers as long as the node at root_path was spawned by one.

Internally, MultiplayerSynchronizer uses MultiplayerAPI.object_configuration_add to notify synchronization start passing the Node at root_path as the object and itself as the configuration, and uses MultiplayerAPI.object_configuration_remove to notify synchronization end in a similar way.

Note: Synchronization is not supported for Object type properties, like Resource. Properties that are unique to each peer, like the instance IDs of Objects (see Object.get_instance_id) or RIDs, will also not work in synchronization.

Properties

Methods

Signals

delta_synchronized() 🔗

Emitted when a new delta synchronization state is received by this synchronizer after the properties have been updated.

synchronized() 🔗

Emitted when a new synchronization state is received by this synchronizer after the properties have been updated.

visibility_changed(for_peer: int) 🔗

Emitted when visibility of for_peer is updated. See update_visibility.

Enumerations

enum VisibilityUpdateMode: 🔗

VisibilityUpdateMode VISIBILITY_PROCESS_IDLE = 0

Visibility filters are updated during process frames (see Node.NOTIFICATION_INTERNAL_PROCESS).

VisibilityUpdateMode VISIBILITY_PROCESS_PHYSICS = 1

Visibility filters are updated during physics frames (see Node.NOTIFICATION_INTERNAL_PHYSICS_PROCESS).

VisibilityUpdateMode VISIBILITY_PROCESS_NONE = 2

Visibility filters are not updated automatically, and must be updated manually by calling update_visibility.

Property Descriptions

float delta_interval = 0.0 🔗

• void set_delta_interval(value: float)

• float get_delta_interval()

Time interval between delta synchronizations. When set to 0.0 (the default), delta synchronizations happen every network process frame.

bool public_visibility = true 🔗

• void set_visibility_public(value: bool)

• bool is_visibility_public()

Whether synchronization should be visible to all peers by default. See set_visibility_for and add_visibility_filter for ways of configuring fine-grained visibility options.

SceneReplicationConfig replication_config 🔗

• void set_replication_config(value: SceneReplicationConfig)

• SceneReplicationConfig get_replication_config()

Resource containing which properties to synchronize.

float replication_interval = 0.0 🔗

• void set_replication_interval(value: float)

• float get_replication_interval()

Time interval between synchronizations. When set to 0.0 (the default), synchronizations happen every network process frame.

NodePath root_path = NodePath("..") 🔗

• void set_root_path(value: NodePath)

• NodePath get_root_path()

Node path that replicated properties are relative to.

If root_path was spawned by a MultiplayerSpawner, the node will be also be spawned and despawned based on this synchronizer visibility options.

VisibilityUpdateMode visibility_update_mode = 0 🔗

• void set_visibility_update_mode(value: VisibilityUpdateMode)

• VisibilityUpdateMode get_visibility_update_mode()

Specifies when visibility filters are updated (see VisibilityUpdateMode for options).

Method Descriptions

void add_visibility_filter(filter: Callable) 🔗

Adds a peer visibility filter for this synchronizer.

filter should take a peer ID int and return a bool.

bool get_visibility_for(peer: int) const 🔗

Queries the current visibility for peer peer.

void remove_visibility_filter(filter: Callable) 🔗

Removes a peer visibility filter from this synchronizer.

void set_visibility_for(peer: int, visible: bool) 🔗

Sets the visibility of peer to visible. If peer is 0, the value of public_visibility will be updated instead.

void update_visibility(for_peer: int = 0) 🔗

Updates the visibility of for_peer according to visibility filters. If for_peer is 0 (the default), all peers’ visibilties are updated.
