[1.9.1] - 2024-04-18

Added

  • Added AnticipatedNetworkVariable, which adds support for client anticipation of NetworkVariable values, allowing for more responsive gameplay (#2820)
  • Added AnticipatedNetworkTransform, which adds support for client anticipation of NetworkTransforms (#2820)
  • Added NetworkVariableBase.ExceedsDirtinessThreshold to allow network variables to throttle updates by only sending updates when the difference between the current and previous values exceeds a threshold. (This is exposed in NetworkVariable with the callback NetworkVariable.CheckExceedsDirtinessThreshold) (#2820)
  • Added NetworkVariableUpdateTraits, which add additional throttling support: MinSecondsBetweenUpdates will prevent the NetworkVariable from sending updates more often than the specified time period (even if it exceeds the dirtiness threshold), while MaxSecondsBetweenUpdates will force a dirty NetworkVariable to send an update after the specified time period even if it has not yet exceeded the dirtiness threshold. (#2820)
  • Added virtual method NetworkVariableBase.OnInitialize() which can be used by NetworkVariable subclasses to add initialization code (#2820)
  • Added virtual method NetworkVariableBase.Update(), which is called once per frame to support behaviors such as interpolation between an anticipated value and an authoritative one. (#2820)
  • Added NetworkTime.TickWithPartial, which represents the current tick as a double that includes the fractional/partial tick value. (#2820)
  • NetworkVariable now includes built-in support for NativeHashSet, NativeHashMap, List, HashSet, and Dictionary (#2813)
  • NetworkVariable now includes delta compression for collection values (NativeList, NativeArray, NativeHashSet, NativeHashMap, List, HashSet, Dictionary, and FixedString types) to save bandwidth by only sending the values that changed. (Note: For NativeList, NativeArray, and List, this algorithm works differently than that used in NetworkList. This algorithm will use less bandwidth for "set" and "add" operations, but NetworkList is more bandwidth-efficient if you are performing frequent "insert" operations.) (#2813)
  • UserNetworkVariableSerialization now has optional callbacks for WriteDelta and ReadDelta. If both are provided, they will be used for all serialization operations on NetworkVariables of that type except for the first one for each client. If either is missing, the existing Write and Read will always be used. (#2813)
  • Network variables wrapping INetworkSerializable types can perform delta serialization by setting UserNetworkVariableSerialization<T>.WriteDelta and UserNetworkVariableSerialization<T>.ReadDelta for those types. The built-in INetworkSerializable serializer will continue to be used for all other serialization operations, but if those callbacks are set, it will call into them on all but the initial serialization to perform delta serialization. (This could be useful if you have a large struct where most values do not change regularly and you want to send only the fields that did change.) (#2813)

Fixed

  • Fixed issue where NetworkTransformEditor would throw and exception if you excluded the physics package. (#2871)
  • Fixed issue where NetworkTransform could not properly synchronize its base position when using half float precision. (#2845)
  • Fixed issue where the host was not invoking OnClientDisconnectCallback for its own local client when internally shutting down. (#2822)
  • Fixed issue where NetworkTransform could potentially attempt to "unregister" a named message prior to it being registered. (#2807)
  • Fixed issue where in-scene placed NetworkObjects with complex nested children NetworkObjects (more than one child in depth) would not synchronize properly if WorldPositionStays was set to true. (#2796)

Changed

  • Changed NetworkObjectReference and NetworkBehaviourReference to allow null references when constructing and serializing. (#2874)
  • Changed NetworkAnimator no longer requires the Animator component to exist on the same GameObject. (#2872)
  • Changed NetworkTransform to now use NetworkTransformMessage as opposed to named messages for NetworkTransformState updates. (#2810)
  • Changed CustomMessageManager so it no longer attempts to register or "unregister" a null or empty string and will log an error if this condition occurs. (#2807)
