Unreleased

Changed

• All TestFnsEntityExt now accept FnsId.

Removed

• FnsInfo, use (ComponentId, FnsId) instead.

0.28.4 - 2024-10-15

Added

• ComponentId to all component-related contexts.

Changed

• All custom functions now accept the newly added DeferredEntity instead of EntityMut. This new entity type provides read-only access to the world.

Fixed

• Synchronize server events with init messages properly when ServerTick is not updated every app tick.

0.28.3 - 2024-09-13

Changed

• Ignore replicated components that don't have type registration or missing #[reflect(Component)] in scene::replicate_into instead of panicking.
• Rename has_authority condition into server_or_singleplayer. Old name still works, but marked as deprecated.

0.28.2 - 2024-09-09

Changed

• Make ReplicatedClients::new public.

0.28.1 - 2024-09-04

Fixed

• Client event buffering.

0.28.0 - 2024-09-03

Added

• ServerEventAppExt::make_independent to let events be triggered without waiting for replication on the same tick.
• ConnectedClients (the same name as the old resource that was renamed into ReplicatedClients) with client IDs for all connected clients (but may not be replicated yet).
• ServerPlugin::replicate_after_connect to enable replication right after connection (enabled by default, same as old behavior).

Changed

• Rename connected_clients into replicated_clients.
• Rename ConnectedClients to ReplicatedClients.
• Rename ConnectedClient to ReplicatedClient.

Fixed

• Emit an error instead of panic on events deserialization on client.
• Buffering for events that have mapped entities.

0.27.0 - 2024-07-04

Changed

• Update to Bevy 0.14.0.
• Move bevy_replicon_renet to a dedicated repository.
• ServerEventsPlugin and ClientEventsPlugin can be disabled on client-only and server-only apps respectively.
• Put ClientDiagnosticsPlugin under client_diagnostics feature (disabled by default) and make it part of the RepliconPlugins group.
• Put scene module under scene feature (enabled by default).
• Put parent_sync module under parent_sync feature (enabled by default).
• Put client module under client feature (enabled by default).
• Put server module under server feature (enabled by default).
• TestFnsEntityExt::serialize now accepts RepliconTick for server tick instead of using ServerTick resource internally.
• Move replicon_client, server_entity_map, replicon_server, connected_clients under core module. These modules are needed for both client and server.
• Move VisibilityPolicy to connected_clients module.
• Move server::events::event_data module to core::event_registry::server_event.
• Move client::events::event_data module to core::event_registry::client_event.
• Move ClientEventAppExt, client::events::SerializeFn, client::events::DeserializeFn, default_serialize, default_serialize_mapped, default_deserialize and FromClient to core::event_registry::client_event.
• Move ServerEventAppExt, server::events::SerializeFn, server::events::DeserializeFn, default_serialize, default_serialize_mapped, default_deserialize, ToClients and SendMode to core::event_registry::server_event.
• Speedup removals caching.

Fixed

• Do not divide values per seconds by the number of messages for ClientDiagnosticsPlugin.

0.26.3 - 2024-06-09

Added

• Logging for sending and receiving messages.

Changed

• Do not send empty ack messages from client.

0.26.2 - 2024-06-05

Added

• Debug/Clone derives to ServerEvent.
• Debug/Copy/Clone derives to TickPolicy.
• ClientSet::SyncHierarchy for ParentSync updates.

0.26.1 - 2024-05-27

Fixed

• Regression in server events reset logic.

0.26.0 - 2024-05-26

Added

• ClientEventsPlugin and ServerEventsPlugin that are required for events (available from the RepliconPlugins group). Can be disabled if you don't use them.

Changed

• Custom events are now registered with serialization and deserialization functions instead of systems. This makes the API more convenient since the purpose of custom systems was to customize serialization.
• All events are processed in one system instead of a separate system for each event. Bevy does a similar optimization for event updates. It won't be that noticeable since users register much fewer replicon events.
• Rename ConnectedClient::change_tick into ConnectedClient::init_tick.
• Rename ConnectedClient::get_change_limit into ConnectedClient::get_change_tick.
• Rename Confirmed into ConfirmHistory.
• Rename replicon_channels module into channels.
• Rename replication_fns and ReplicationFns into replication_registry and ReplicationRegistry.
• Rename "packets" into "messages" in client diagnostics.

Fixed

• bevy_replicon_renet now properly sets RepliconClientStatus::Connecting when RenetClient is connecting.

0.25.3 - 2024-05-24

Fixed

• Fix replication with a removal at the same tick.

0.25.2 - 2024-05-18

Fixed

• Fix replicating previously spawned entities to a newly connected client with visibility policy different from VisibilityPolicy::All.

0.25.1 - 2024-05-16

Fixed

• Fix possible overflow in Confirmed::contains_any.

0.25.0 - 2024-05-11

Added

• AppMarkerExt to customize how components will be written based on markers present without overriding deserialization functions. Now third-party prediction crates could be integrated much easier.
• AppRuleExt::replicate_group and GroupRegistration trait to register and customize component groups. A group will be replicated only if all its components present on an entity.
• ServerSet::StoreHierarchy for systems that store hierarchy changes in ParentSync.
• More tracing.
• Debug impl for RepliconClientStatus.

Changed

• SerializeFn now accepts regular C instead of Ptr.
• DeserializeFn now does only deserialization and returns C. Use the newly added marker-based API if you want to customize how component will be written. See docs for AppMarkerExt for details.
• Rename AppReplicationExt into AppRuleExt.
• AppRuleExt::replicate_with now accepts RuleFns struct with functions. You no longer can customize removals this way, use the mentioned marker-based API instead.
• Writing to entities on client now done via EntityMut and Commands instead of EntityWorldMut. It was needed to support the mentioned in-place deserialization and will possibly allow batching insertions in the future (for details see bevyengine/bevy#10154).
• Return iterator from RepliconClient::receive instead of popping the last message. If you used while loop with it before, replace it with for.
• Use new ServerInitTick resource on client instead of RepliconTick. If you used ServerEventAppExt::add_server_event_with, use ServerInitTick instead of RepliconTick in your receive function.
• Use new ServerTick resource on server instead of RepliconTick.
• Replace ServerEntityTicks with Confirmed component. The component now also stores whether the last 64 ticks were received.
• Now serialization/deserialization, removal, despawn and writing functions accept context to access additional information.
• Move replicon_tick module under server module since now it's used only on server.
• Move Replication to core module.
• Move all functions-related logic from ReplicationRules into a new ReplicationFns and hide ReplicationRules from public API.
• Move despawn_recursive into replication_fns module.
• Rename serialize_component into default_serialize and move into rule_fns module.
• Rename deserialize_component into default_deserialize and move into rule_fns module.
• Rename deserialize_mapped_component into default_deserialize_mapped and move into rule_fns module.
• Rename remove_component into default_remove and move into command_fns module.

Removed

• dont_replicate module. Use the newly added AppRuleExt::replicate_group or newtypes.

Fixed

• Reversed order of the received messages from RepliconClient.

0.24.1 - 2024-03-07

Fixed

• Fix compilation issue when multiple PartialEq impls are present for usize.

0.24.0 - 2024-03-06

Added

• Provide ServerTestAppExt extension trait for exchanging messaging between apps in tests.

Changed

• Rename Replication into Replicated. Old name is still available via deprecated alias.
• Abstract out all I/O and renet dependency. We will continue to provide first-party integration with renet via bevy_replion_renet. But users can write their integration with other messaging libraries. So now users need to additionally add messaging-related plugin. In case of bevy_replion_renet it's RepliconRenetPlugins.
• Replace usage of RenetServer and RenetClient with our RepliconServer and RepliconClient respectively. Use types from renet (or other library) only when you need to connect / disconnect or write some library-specific logic. In other cases prefer using the newly provided types to make your code messaging-library independent. Unlike the old types from renet, these resources are always present in the world. So instead of using resource_(exists/added/removed) for network-related conditions, use special conditions provided in common_conditions module.
• Move has_authority to common_conditions module.
• Replace conditions from renet with ours, see common_conditions module. Available in prelude.
• Replace usage of ClientId from renet with our own with the same name. In user code only the one from bevy_replicon should be used.
• Replace SERVER_ID constant with ClientId::SERVER.
• Replace use of RenetConnectionStatus with our RepliconClientStatus.
• Replace ServerEvent from renet with our own with the same name. In user code only the one from bevy_replicon should be used.
• Rename replicon_core module into core.
• Rename EventType into ChannelKind and move into core module.
• Replace usage of renet's SendType with our RepliconChannel.
• Rename NetworkChannels into RepliconChannels and move into replicon_channels module.
• Rename ReplicationChannel::Reliable and ReplicationChannel::Unreliable into ReplicationChannel::Init and ReplicationChannel::Update respectively.
• Channel creation methods in RepliconChannels now accept RepliconChannel with full channel configuration.
• Make default_max_bytes field in RepliconChannels public.
• Move RepliconChannels::get_server_configs and RepliconChannels::get_client_configs to create channels configs for renet into RenetChannelsExt extension trait provided by bevy_replion_renet. Make sure to import it to use these methods.
• Move ClientEntityMap and ClientMapping to client_entity_map submodule.
• Rename ReplicationPlugins into RepliconPlugins.
• Rename ClientCache into ConnectedClients.
• Rename ClientState into ConnectedClient.
• Replace RepliconChannels::set_client_max_bytes and RepliconChannels::set_server_max_bytes with RepliconChannels::server_channel_mut and RepliconChannels::client_channel_mut respectively with more rich configuration.
• Move ClientEventChannel to client_event module.
• Move ServerEventChannel to server_event module.
• ClientMapper, ServerEntityMap, BufferedUpdates, ReplicationRules, ReplicationChannel, ClientEventChannel, ServerEventChannel, ServerEventQueue and EventMapper are no longer in prelude module. Import them directly.

0.23.0 - 2024-02-22

Changed

• Common conditions now follow the new pattern without returning a closure.

Removed

Fixed

• Make scene::replicate_into update previously added entities.

0.22.0 - 2024-02-17

Changed

• Change ClientEventAppExt::add_mapped_client_event to clone the events instead of draining them. This means that mapped client events must now implement Clone

Fixed

• Misuse of Vec::reserve that would cause excess allocations.

0.21.2 - 2024-01-27

Changes

• Increase publicity of ClientState API.

0.21.1 - 2024-01-22

Added

• dont_replicate::<T> can panic only in debug_assertions is enabled.

0.20.0 - 2024-01-13

Changed

• API for custom server messages now uses server_event::serialize_with and server_event::deserialize_with. For more details see the example in the docs.
• Speedup serialization for multiple clients by reusing already serialized components and entities.
• Hide extra functionality from ServerEventQueue.
• Move server event reset system to new set ClientSet::ResetEvents in PreUpdate.
• Make NetworkChannels channel-creation methods public (create_client_channel() and create_server_channel()).

0.18.2 - 2023-12-27

Fixed

• Fix missing removals and despawns caused by events cleanup.

0.18.1 - 2023-12-21

Changed

• Cache replicated archetypes for faster iteration.

Fixed

• Fix crash caused by registering the same type for client and server events.
• Fix replication for entities when Replication component is added after spawn.

0.18.0 - 2023-12-19

Changed

• Send all component mappings, inserts, removals and despawns over reliable channel in form of deltas and component updates over unreliable channel packed by packet size. This significantly reduces the possibility of packet loss.
• Replace REPLICATION_CHANNEL_ID with ReplicationChannel enum. The previous constant corresponded to the unreliable channel.
• Server events use tick with the last change instead of waiting for replication message without changes.
• Include despawns before removals to optimize space for case where despawns are presents and removals aren't.
• TickPolicy::EveryFrame and TickPolicy::MaxTickRate now increment tick only if RenetServer exists.

• Rename replicate_into_scene into replicate_into and move it to scene module.
• Derive Debug for Replication and Ignored<T>.

Removed

• AckedTicks resource.

• Fix replication of removals that happened after replication on the same frame.

0.17.0 - 2023-11-13

Added

• Tracing for replication messages.
• Debug derive for LastRepliconTick.

Changed

• Update to Bevy 0.12.

0.16.0 - 2023-10-30

Added

• API to configure max channel usage bytes in NetworkChannels.

Changed

• Rename SendPolicy into EventType.
• Rename NetworkChannels::server_channels into NetworkChannels::get_server_configs.
• Rename NetworkChannels::client_channels into NetworkChannels::get_client_configs.

0.15.1 - 2023-10-22

Changed

• Register Replication type and add #[reflect(Component)].

0.15.0 - 2023-10-21

Added

• network_event::server_event::send helper for server events in custom sending functions.
• Optional ClientDiagnosticsPlugin, which writes diagnostics every second.
• Reflect derive for Replication.

Changed

• Optimize despawn tracking.
• Hide id field in EventChannel and add Clone and Copy impls for it.
• Remove special functions for reflect events and advise users to write them manually instead. Reflect events are easier now because sometimes you can directly use reflect serializers from Bevy instead of manually writing serde traits.
• Do no trigger server events before world update arrival.

Removed

• Debug requirement for events.

0.14.0 - 2023-10-05

Added

• The ability to pre-spawn entities on client.

Changed

• Rename NetworkEntityMap to ServerEntityMap.

0.13.0 - 2023-10-04

Added

• The ability to set custom despawn and component removal functions.
• TickPolicy::EveryFrame to update RepliconTick every frame.

Changed

• Use more compact varint encoding for entities.
• Now all replication functions accept RepliconTick.
• Rename NetworkTick into RepliconTick and move it into server module.
• Rename LastTick into LastRepliconTick.

Removed

• derive_more dependency.

Fixed

0.12.0 - 2023-10-01

Added

• High-level API to extract replicated entities into DynamicScene.

Changed

• Hide ReplicationRules from public API.
• Move logic related to replication rules to replicon_core::replication_rules module.

0.11.0 - 2023-09-25

Changed

• Serialize all components and events using varint.
• Serialize entities in optimal way by writing its index and generation as separate varints.
• Hide ReplicationId, ReplicationInfo and related methods from ReplicationRules from public API.
• Rename ReplicationRules::replication_id into ReplicationRules::replication_marker_id.
• Use serialization buffer cache per client for replication.
• Correctly handle old values on packet reordering.
• Bevy's Tick was replaced with dedicated type NetworkTick that increments on server update, so it can be used to provide information about time. AckedTick was replaced with ServerTicks that also contains mappings from NetworkTick to Bevy's Tick and current NetworkTick.
• Functions in AppReplicationExt::replicate_with now accept bytes cursor for memory reuse and return serialization errors.
• Rename ReplicationCore into RepliconCore with its module for clarity.
• MapNetworkEntities now accepts generic Mapper and doesn't have error handling and deserialiation functions now accept NetworkEntityMap. This allowed us to lazily map entities on client without extra allocation.
• Make LastTick public.

0.10.0 - 2023-09-13

Changed

• MapEventEntities was renamed into MapNetworkEntities and now used for both components and events. Built-in MapEntities trait from Bevy is not suited for network case for now.
• AppReplicationExt::not_replicate_with was replaced with component marker Ignored<T>.
• Reflection was replaced with plain serialization. Now components need to implement serde traits and no longer need any reflection. This reduced reduced message sizes a lot. Because of this mapped components now need to be registered with AppReplicationExt::replicate_mapped.
• Derive Clone and Copy for Replication.
• Make ServerPlugin fields private and add ServerPlugin::new.
• Make AckedTicks public.
• Make NetworkEntityMap public.

Changed

• Re-export transport module from bevy_renet.

0.7.0 - 2023-07-20

Changed

• Mappable network events now need to implement MapEventEntities instead of MapEntities.

Removed

• ClientState and ServerState, use conditions from bevy_renet and resource_added() / resource_exists() / resource_removed().
• ServerSet::Authority, use has_authority() instead.

0.6.1 - 2023-07-09

Changed

• Update ParentSync in CoreSet::PostUpdate to avoid one frame delay.

0.6.0 - 2023-07-08

Added

0.5.0 - 2023-06-26

Added

• ServerSet::ReceiveEvent and ServerSet::SendEvent for more fine-grained control of scheduling for event handling.

Changed

• Update server to use TickPolicy instead of requiring a tick rate.

Fixed
