Netcode for GameObjects is a high-level netcode SDK that provides networking capabilities to GameObject/MonoBehaviour workflows within Unity and sits on top of underlying transport layer.
NetworkBehaviour.OnSynchronize which is invoked during the initial NetworkObject synchronization process. This provides users the ability to include custom serialization information that will be applied to the NetworkBehaviour prior to the NetworkObject being spawned. (#2298)NetworkObject auto-add helper and Multiplayer Tools install reminder settings to Project Settings. (#2285)public string DisconnectReason getter to NetworkManager and string Reason to ConnectionApprovalResponse. Allows connection approval to communicate back a reason. Also added public void DisconnectClient(ulong clientId, string reason) allowing setting a disconnection reason, when explicitly disconnecting a client. (#2280)XXHash (32 & 64) implementation with an in-house reimplementation (#2310)NetworkConfig.EnsureNetworkVariableLengthSafety is disabled NetworkVariable fields do not write the additional ushort size value (which helps to reduce the total synchronization message size), but when enabled it still writes the additional ushort value. (#2298)NetworkTransform components nested under a parent with a NetworkObject component (i.e. network prefab) would not have their associated GameObject's transform synchronized. (#2298)NetworkObjects that failed to instantiate could cause the entire synchronization pipeline to be disrupted/halted for a connecting client. (#2298)NetworkObjects nested under a GameObject would be added to the orphaned children list causing continual console warning log messages. (#2298)UnityTransport where an error would be logged if the 'Use Encryption' flag was enabled with a Relay configuration that used a secure protocol. (#2289)NetworkObjects were not honoring the AutoObjectParentSync property. (#2281)NetworkManager.OnClientConnectedCallback was being invoked before in-scene placed NetworkObjects had been spawned when starting NetworkManager as a host. (#2277)FastBufferReader with Allocator.None will not result in extra memory being allocated for the buffer (since it's owned externally in that scenario). (#2265)NetworkObject auto-add and Multiplayer Tools install reminder settings from the Menu interface. (#2285)NetworkManager.IsApproved flag that is set to true a client has been approved.(#2261)UnityTransport now provides a way to set the Relay server data directly from the RelayServerData structure (provided by the Unity Transport package) throuh its SetRelayServerData method. This allows making use of the new APIs in UTP 1.3 that simplify integration of the Relay SDK. (#2235)UnityTransport. (#2232)UseWebSockets property in the UnityTransport component of the NetworkManager allowing to pick WebSockets for communication. When building for WebGL, this selection happens automatically. (#2201)ParentSyncMessage which provides users the ability to specify the final values on the server-side when OnNetworkObjectParentChanged is invoked just before the message is created (when the Transform values are applied to the message). (#2146)NetworkObject.TryRemoveParent method for convenience purposes opposed to having to cast null to either GameObject or NetworkObject. (#2146)UnityTransport dependency on com.unity.transport to 1.3.0. (#2231)UnityTransport are now dynamically-sized. This means that there shouldn't be any need anymore to tweak the 'Max Send Queue Size' value. In fact, this field is now removed from the inspector and will not be serialized anymore. It is still possible to set it manually using the MaxSendQueueSize property, but it is not recommended to do so aside from some specific needs (e.g. limiting the amount of memory used by the send queues in very constrained environments). (#2212)UnityTransport.InitialMaxSendQueueSize field is now deprecated. There is no default value anymore since send queues are dynamically-sized. (#2212)UnityTransport is now non-deterministic. Its random number generator used to be seeded with a constant value, leading to the same pattern of packet drops, delays, and jitter in every run. (#2196)NetworkVariable<> now supports managed INetworkSerializable types, as well as other managed types with serialization/deserialization delegates registered to UserNetworkVariableSerialization<T>.WriteValue and UserNetworkVariableSerialization<T>.ReadValue (#2219)NetworkVariable<> and BufferSerializer<BufferSerializerReader> now deserialize INetworkSerializable types in-place, rather than constructing new ones. (#2219)NetworkManager.ApprovalTimeout will not timeout due to slower client synchronization times as it now uses the added NetworkManager.IsApproved flag to determined if the client has been approved or not.(#2261)NetworkConfig hash value for each unique connection request. (#2226)DontDestroyWithOwner property into consideration when a client disconnected. (#2225)SceneEventProgress would not complete if a client late joins while it is still in progress. (#2222)SceneEventProgress would not complete if a client disconnects. (#2222)SceneEventProgress has timed out. (#2222)UnityTransport would fail to restart after a first failure (even if what caused the initial failure was addressed). (#2220)NetworkTransform.SetStateServerRpc and NetworkTransform.SetStateClientRpc were not honoring local vs world space settings when applying the position and rotation. (#2203)TypeLoadException on WebGL on MacOS Editor and potentially other platforms. (#2199)WorldPositionStays parenting parameter was not being synchronized with clients. (#2146)NetworkObjects would fail for late joining clients. (#2146)WorldPositionStays was true. (#2146)NetworkTransform.ApplyTransformToNetworkStateWithInfo where it was not honoring axis sync settings when NetworkTransformState.IsTeleportingNextFrame was true. (#2146)NetworkTransform.TryCommitTransformToServer where it was not honoring the InLocalSpace setting. (#2146)ClientRpcParams. (#2144)FastBufferReader and FastBufferWriter when the parameters were a generic type (i.e., ListOnNetworkUpdate causing other OnNetworkUpdate calls to not be executed. (#1739)NetworkTransform was not honoring the InLocalSpace property on the authority side during OnNetworkSpawn. (#2170)NetworkTransform was not ending extrapolation for the previous state causing non-authoritative instances to become out of synch. (#2170)NetworkTransform was not continuing to interpolate for the remainder of the associated tick period. (#2170)NetworkTransform.OnNetworkSpawn for non-authoritative instances where it was initializing interpolators with the replicated network state which now only contains the transform deltas that occurred during a network tick and not the entire transform state. (#2170)com.unity.transport to 1.2.0. (#2129)UnityTransport, reliable payloads are now allowed to exceed the configured 'Max Payload Size'. Unreliable payloads remain bounded by this setting. (#2081)NetworkTransformState.m_Bitset flag not getting cleared upon the next tick advancement. (#2110)NetworkTransform.Teleport. (#2110)NetworkVariable with both owner read and write permissions would not update the server side when changed. (#2097)GameObject, with NetworkObject component attached, that has one or more child GameObjects, that are inactive in the hierarchy, with NetworkBehaviour components it will no longer attempt to spawn the associated NetworkBehaviour(s) or invoke ownership changed notifications but will log a warning message. (#2096)NetworkObject.NetworkHide was despawning and destroying, as opposed to only despawning, in-scene placed NetworkObjects. (#2086)NetworkAnimator synchronizing transitions twice due to it detecting the change in animation state once a transition is started by a trigger. (#2084)NetworkAnimator would not synchronize a looping animation for late joining clients if it was at the very end of its loop. (#2076)NetworkAnimator was not removing its subscription from OnClientConnectedCallback when despawned during the shutdown sequence. (#2074)com.unity.transport to 1.2.0. (#2129)UnityTransport, reliable payloads are now allowed to exceed the configured 'Max Payload Size'. Unreliable payloads remain bounded by this setting. (#2081)NetworkTransformState.m_Bitset flag not getting cleared upon the next tick advancement. (#2110)NetworkTransform.Teleport. (#2110)NetworkVariable with both owner read and write permissions would not update the server side when changed. (#2097)GameObject, with NetworkObject component attached, that has one or more child GameObjects, that are inactive in the hierarchy, with NetworkBehaviour components it will no longer attempt to spawn the associated NetworkBehaviour(s) or invoke ownership changed notifications but will log a warning message. (#2096)NetworkObject.NetworkHide was despawning and destroying, as opposed to only despawning, in-scene placed NetworkObjects. (#2086)NetworkAnimator synchronizing transitions twice due to it detecting the change in animation state once a transition is started by a trigger. (#2084)NetworkAnimator would not synchronize a looping animation for late joining clients if it was at the very end of its loop. (#2076)NetworkAnimator was not removing its subscription from OnClientConnectedCallback when despawned during the shutdown sequence. (#2074)OnTransportFailure callback to NetworkManager. This callback is invoked when the manager's NetworkTransport encounters an unrecoverable error. Transport failures also cause the NetworkManager to shut down. Currently, this is only used by UnityTransport to signal a timeout of its connection to the Unity Relay servers. (#1994)NetworkEvent.TransportFailure, which can be used by implementations of NetworkTransport to signal to NetworkManager that an unrecoverable error was encountered. (#1994)NetworkManager.RemoveNetworkPrefab(...) to remove a prefab from the prefabs list (#1950)UnityTransport dependency on com.unity.transport to 1.1.0. (#2025)ConnectionApprovalCallback is no longer an event and will not allow more than 1 handler registered at a time. Also, ConnectionApprovalCallback is now an Action<> taking a ConnectionApprovalRequest and a ConnectionApprovalResponse that the client code must fill (#1972) (#2002)NetworkObjects could throw an exception if the scene of origin handle was zero (0) and the NetworkObject was already spawned. (#2017)NetworkObject.Observers was not being cleared when despawned. (#2009)NetworkAnimator could not run in the server authoritative mode. (#2003)NetworkObject. (#1985)NetworkBehaviourReference would throw a type cast exception if using NetworkBehaviourReference.TryGet and the component type was not found. (#1984)NetworkSceneManager was not sending scene event notifications for the currently active scene and any additively loaded scenes when loading a new scene in LoadSceneMode.Single mode. (#1975)LoadEventCompleted or UnloadEventCompleted to wait until the NetworkConfig.LoadSceneTimeOut period before being triggered. (#1973)ConnectionApprovalCallbacks were registered (#1972)FixedString, Vector2Int, and Vector3Int types can now be used in NetworkVariables and RPCs again without requiring a ForceNetworkSerializeByMemcpy<> wrapper. (#1961)NetworkBehaviour to a NetworkManager or vice-versa. (#1947)NetworkAnimator issue where it was only synchronizing parameters if the layer or state changed or was transitioning between states. (#1946)NetworkAnimator issue where when it did detect a parameter had changed it would send all parameters as opposed to only the parameters that changed. (#1946)NetworkAnimator issue where it was not always disposing the NativeArray that is allocated when spawned. (#1946)NetworkAnimator issue where it was not taking the animation speed or state speed multiplier into consideration. (#1946)NetworkAnimator issue where it was not properly synchronizing late joining clients if they joined while Animator was transitioning between states. (#1946)NetworkAnimator issue where the server was not relaying changes to non-owner clients when a client was the owner. (#1946)PacketLoss metric for tools would return the packet loss over a connection lifetime instead of a single frame. (#2004)unmanaged structs are no longer universally accepted as RPC parameters because some structs (i.e., structs with pointers in them, such as NativeList<T>) can't be supported by the default memcpy struct serializer. Structs that are intended to be serialized across the network must add INetworkSerializeByMemcpy to the interface list (i.e., struct Foo : INetworkSerializeByMemcpy). This interface is empty and just serves to mark the struct as compatible with memcpy serialization. For external structs you can't edit, you can pass them to RPCs by wrapping them in ForceNetworkSerializeByMemcpy<T>. (#1901)Removed SIPTransport (#1870)
Removed ClientNetworkTransform from the package samples and moved to Boss Room's Utilities package which can be found here.
NetworkTransform generating false positive rotation delta checks when rolling over between 0 and 360 degrees. (#1890)NetworkEvent.Disconnect event and is using UTP. (#1884)Shutdown on a NetworkManager that was already shut down would cause an immediate shutdown the next time it was started (basically the fix makes Shutdown idempotent). (#1877)UnityTransport implementation and com.unity.transport package dependency (#1823)NetworkVariableWritePermission to NetworkVariableBase and implemented Owner client writable netvars. (#1762)UnityTransport settings can now be set programmatically. (#1845)FastBufferWriter and Reader IsInitialized property. (#1859)UnityTransport dependency on com.unity.transport to 1.0.0 (#1849)SnapshotSystem (#1852)com.unity.modules.animation, com.unity.modules.physics and com.unity.modules.physics2d dependencies from the package (#1812)com.unity.collections dependency from the package (#1849)UnityTransport send queues were not flushed when calling DisconnectLocalClient or DisconnectRemoteClient. (#1847)
