To load addressable scenes, simply use NetworkRunner.SetActiveScene with either a correct SceneRef or the addressable scene path

Improvements

• Improved the performance of 2D and 3D NetworkRigidbody behaviours by preventing multiple calls to SyncTransforms
• Reduced bandwidth consumption of 2D and 3D NetworkRigidbody behaviours

Changes

1.1.5

F

Build 640 (Nov 30, 2022)

What's New

• StartGameResult.ErrorMessage
• NetworkArray<T>.GetRef(int) - an extension method that returns a reference to a selected element.

Build 497 (May 31, 2022)

What's New

• ILWeaver: support for Wrapping/Unwrapping without a NetworkRunner. There are three constructs Fusion supports:

    public struct Wrapper : INetworkStruct {  
       ...  
    }  
    public class WrappedByValue {  
      [NetworkSerializeMethod]   public static Wrapper Wrap(WrappedByValue obj) { ... };  
      [NetworkDeserializeMethod] public static WrappedByValue Unwrap(Wrapper wrapper) { ... }  
    }  
    public class WrappedByRef {  
      [NetworkSerializeMethod]   public static Wrapper Wrap(WrappedByRef obj) { ... }  
      [NetworkDeserializeMethod] public static void Unwrap(Wrapper wrapper, ref WrappedByRef result) { ... }  
    }  
    // both methods return number of bytes read/written  
    public class WrappedRaw {  
      [NetworkSerializeMethod(MaxSize = ...)] public static int Wrap(WrappedRaw obj, byte* data) { ... }  
      [NetworkDeserializeMethod] public static int Unwrap(byte* data, ref WrappedRaw result) { ... }  
    }

Build 423 (Feb 24, 2022)

What's New

• Support DisableSessionCreation in SharedMode

• Reworked transform behaviours: NetworkTransform, NetworkRigidbody and NetworkCharacterController.
  This build brings an important rework to all core transform behaviours. Here is a summary of why we needed those modifications, what to expect and the most important changes.

  Why:

  • The previously available behaviours (NT/NRB/NCC) aimed to solve a very broad range of problems and scenarios, which led to a complex and hard to maintain codebase that sometimes misbehaved on core use-cases.
  • While possible, user extension of these default functionalities and options provided by those behaviours was not easy. This prevented users from customizing them to their needs, often relying on modifications of the core implementation.
  • NCC was unstable even when steering over simple scene colliders. The release of the new advanced KCC package further reduced its value even as a prototyping tool.

  What to expect:

  • New behaviours are easier to configure and are expected to be more stable in most common use-cases.
  • They are also easier to extend and adjust for game specific needs. A new prototype component exemplifies exactly that (more below).

  Important changes:

  • All previously existing core transform behaviours are marked as obsolete and renamed, but were kept in the core libraries. Although their usage is no longer encouraged and provided support for them will be limited, they are still available if you want to upgrade but need more time to switch to the new behaviours.
  • All new behaviours have the same name as the previous ones (e.g. NetworkTransform), except for NetworkCharacterController and NetworkTransformAnchor, which don't have a counterpart on new behaviours. To make this possible, old behaviours were renamed and have Obsolete added at the end of the class name: e.g. old NetworkRigidbody will be available as NetworkRigidbodyObsolete (the class is also marked as obsolete). Keeping the same name on the new behaviours also means that your existing prefabs and scene objects will automatically upgrade to use the new ones.
  • There is no longer a core NCC behaviour (existing one is kept, but marked as obsolete). Instead, a new NetworkCharacterControllerPrototype is provided in source code on the SDK: it uses Unity's Character Controller and exemplifies how the base NetworkTransform behaviour can be extended. With this new prototype behaviour we aim to provide a simple, yet stable prototyping tool, while the KCC package remains the recommended one for production and more complex use-cases.
  • Transform data is now always synchronized in world space. This is important to ensure Area of Interest (AOI) management works as expected. However, a configurable Interpolation Space will be available for all transform behaviours, so that the view (interpolation target) can be interpolated as if the networked data is in local space, allowing nested transforms to visually behave as expected. Interpolated prediction error correction is still always performed in world space and more complex hierarchies might require thoughtful control of the interpolation source, space and targets' hierarchies.
  • There is no synchronization of neither scale nor parenting/hierarchy on the transform behaviours. If you need to synchronize these types of data/relations, the suggested approach is to extend the core behaviours, synchronizing scale in local space and controlling a decoupled hierarchy of the interpolation targets.
  • Performing non-interpolated teleports no longer requires pre-steps. Optional interpolation velocities can be provided in order to smooth the transition. Check the new teleport API documentation for more details

Improvements

• Networked transform behaviours now have prediction error computed based on both From and To states used for rendering, instead of only on the latter

Bug Fixes

• Fixed: Issue with area of interest calculations when no compression was used for position
• Fixed: Detection of rotation prediction error on NetworkTransform and derived behaviours

Build 419 (Feb 22, 2022)

What's New

• NetworkProjectConfig.NullChecksForNetworkedProperties

Changes

Bug Fixes

• Fixed: Issue with unity infinite loop/freeze when adding an simulation behaviour that was already in the update loop
• Fixed: Issue with AOI when Position accuracy compression is set to not compress
• Fixed: Spawned being called before Awake for initially deactivated objects. This only works if NetworkBehaviour subclasses have execution order (0 by default) lower than NetworkObject (500 by default). If this is not the case, a warning will be emit while baking scene/prefab with disabled objects containing such scripts

What's New

• [NetworkPrefab] attribute. When added to a NetworkObject field, the object picker will only show prefabs with FusionPrefab label.
  Remove: NetworkProjectConfig.PrefabSources: prefab source information is now stored in config's hidden nested assets and is generated based on prefabs marked with FusionPrefab label. This means that serialized config is now a lot smaller as it does not contain prefab information directly

Changes

• Prefabs with NetworkObject script are now labeled with FusionPrefab label during import

Build 290 (Sep 13, 2021)

What's New

• [NetworkSerializeMethod] and [NetworkDeserializeMethod] attributes. Together they can make any type Fusion-serializable (usable in [Networked] properties and in Rpcs).
