Changelog

Unreleased

1.5.3

Changed

  • Profile Markers are now disabled by default. Use the UPDATE_MANAGER_ENABLE_PROFILER_MARKERS scripting symbol to enable them.

Fixed

  • Support for projects with domain reload disabled.

1.5.2

Changed

  • UpdateManager now disables itself while no updatable objects are registered.
  • UpdateManager is now supported in edit mode. The singleton update manager created in edit mode will be destroyed when entering play mode.
  • Enabled AManagedBehaviour objects with [ExecuteInEditMode] or [ExecuteAlways] attributes have their ManagedUpdate and ManagedLateUpdate methods run in edit mode.

1.5.1

Added

  • Support for editing multiple objects in AJobBehaviourEditor

1.5.0

Added

  • IBurstUpdateJob<> and IBurstUpdateTransformJob<> interfaces to be used in place of IUpdateJob and IUpdateTransformJob when Burst compilation is desired. Pass BurstUpdateJob<...> and BurstUpdateTransformJob<...> to their type parameters, so that Burst can compile the concrete job types.

Deprecated

  • AJobBehaviour<,>, IJobUpdatable<,> and ITransformJobUpdatable<,>. Use the versions with a single type parameter instead. Now that Burst support was moved to IBurstUpdateJob<> and IBurstUpdateTransformJob<>, specified at job struct definition, there is no need to specify the second parameter in job updatable types.

1.4.1

Fixed

  • Removed usage of ConditionalWeakTable from ProfilerMarkerMap implementation, which broke iOS + IL2CPP builds for some reason.

1.4.0

Added

  • BurstUpdateJob<>/BurstUpdateTransformJob<>: Burst-compiled versions of UpdateJob<>/UpdateTransformJob<>
  • Update job managers now support job data synchronization. Implement IJobDataSynchronizer<> in job providers to synchronize data from registered jobs. Data synchronization occurs right after completing jobs, but before scheduling the new batch, so it is safe to modify their data. One must explicitly register objects for data synchronization by calling SynchronizeJobDataOnce for a one-time data synchronization next frame, or by passing true to RegisterInManager to sync data every frame.

Changed

  • UpdateJob<>/UpdateTransformJob<> are not marked for compilation with Burst anymore. This avoids warnings about the job being marked for compilation, but no concrete version of the type being defined. Use BurstUpdateJob<>/BurstUpdateTransformJob<> instead if you want Burst-compiled update jobs.
  • AUpdateJobManager.IsRegistered now checks for pending additions/removals. It now returns true if provider is already pending addition and returns false if provider is present in map, but also pending removal.

1.3.0

Added

  • Follow Target sample.
  • AUpdateJobManager.IsRegistered method to check if an object is registered for updates. Extension methods IJobUpdatable.IsRegisteredInManager and ITransformJobUpdatable.IsRegisteredInManager were also added.
  • Profiler markers for methods managed by UpdateManager.

Changed

  • Only reallocate job data arrays when growing their capacity. This avoids CPU spikes when rapidly removing/adding objects in update job managers.
  • Hold Burst shared static in a variable instead of calling GetOrCreate everytime UpdateJobTime is accessed.
  • Use a custom SortedList implementation instead of SortedSet. This avoids heap allocations while iterating over the values.

Fixed

  • Dispose of dependency job handles array before reallocating it.
  • Reset job data when removing and re-adding an object in the same frame. This avoids maintaining the wrong state between registrations.

1.2.0

Added

  • Support for managed LateUpdate and FixedUpdate methods in UpdateManager. Similar to managed Update methods, all you need to do is inherit the ILateUpdatable or IFixedUpdatable interface and register the object in the manager using the RegisterInManager() extension method.

Deprecated

  • AUpdateManagerBehaviour: Prefer inheriting AManagedBehaviour and implementing the IUpdatable/ILateUpdatable/IFixedUpdatable interfaces directly.

Fixed

  • UpdateJobTime.frameCount type to be int instead of float. This makes it compatible with UnityEngine.Time.frameCount.

1.1.2

Changed

  • UpdateManager now uses try/catch blocks for each ManagedUpdate call. This way, if any managed update call fails, the other ones are not affected.

1.1.1

Changed

  • UpdateJob<> and UpdateTransformJob<> are now marked for Burst compilation. Simply use concrete types and Burst will compile the jobs.
  • AJobBehaviour<,> now inherits AJobBehaviour<> and not the other way around. The same is true for IJobUpdatable<,> and ITransformJobUpdatable<,>.

Removed

  • BurstUpdateJob<> and BurstUpdateTransformJob<> types. Simply use UpdateJob<> and UpdateTransformJob<> instead.
  • UpdateJobManager<,> and UpdateTransformJobManager<,>, which are not necessary anymore.

Fixed

  • Managed jobs with dependencies now work for Burst-compiled jobs.

1.1.0

Added

  • AJobBehaviour custom editor that shows current job data in a JSON format while inspecting the object.
  • Added support for Burst-compiled jobs by specifying BurstUpdateJob<> or BurstUpdateTransformJob<> as the second type parameter to the generic interfaces IJobUpdatable<,> and ITransformJobUpdatable<,> as well as AJobBehaviour<,>.
  • Added support for dependencies between managed jobs by using the [DependsOn(...)] attribute. For now, no dependency cycle detection is performed, so job runners may get deadlocked if you misuse it.
  • Added support for native collections as fields in managed jobs. For now, the thread safety system provided by Unity is not applied to managed jobs native containers, so use them with care!
  • [JobBatchSize(...)] attribute for specifying the parallel job batch sizes for each job type.
  • [ReadOnlyTransformAccess] attribute for marking IUpdateTransformJobs with read-only transform access.
  • UpdateJobTime now has static properties with names equal to the ones in UnityEngine.Time, no need to access using UpdateJobTime.Instance anymore.

Deprecated

  • Deprecated the [UpdateJobOptions(...)] attribute, use [JobBatchSize(...)] and [ReadOnlyTransformAccess] instead. They are clearer to read in code.

Changed

  • Deduplicated code in UpdateJobManager and UpdateTransformJobManager by using the common base class AUpdateJobManager.
  • UpdateManager.Unregister complexity is now O(1) instead of O(N). This is due to using an internal Dictionary for caching objects' indices and always removing objects with swap back, the same technique used by AUpdateJobManager.
  • UpdateJobTime is now a struct instead of class and its usage is now supported in Burst-compiled jobs.

Fixed

  • Calling UpdateManager.Register with an already registered object is now a no-op instead of registering duplicated entries.

1.0.0

Added

  • UpdateManager singleton class that runs managed update methods in registered objects. Supports any C# object that implements IUpdatable, including MonoBehaviours, pure C# classes and structs.
  • AUpdateManagerBehaviour, a MonoBehaviour abstract subclass that automatically registers/unregisters itself in UpdateManager.
  • UpdateJobManager<> singleton class that schedules jobs with data provided by registered objects. Supports any C# object that implements IJobUpdatable<>.
  • UpdateTransformJobManager<> singleton class that schedules TransformAccess-enabled jobs with data provided by registered objects. Supports any C# object that implements ITransformJobUpdatable<>.
  • UpdateJobTime singleton class for accessing UnityEngine.Time properties from jobs.
  • AJobBehaviour<>, a MonoBehaviour abstract subclass that automatically registers/unregisters itself in UpdateTransformJobManager<>.
  • [UpdateJobOptions(...)] attribute that specifies parallel job batch sizes and whether transforms are read-only.
