Package Dependencies

✨ Features

  • Script templates have been added to help you create new component types and systems, similar to Unity's built-in template for new MonoBehaviours. Use them via the Assets/Create/ECS menu.
  • ### Upgrade guide
  • Some APIs have been deprecated in this release:
  • API Deprecation FAQ
  • \*\* Removed obsolete ComponentSystem.ForEach \*\* Removed obsolete [Inject] \*\* Removed obsolete ComponentDataArray \*\* Removed obsolete SharedComponentDataArray \*\* Removed obsolete BufferArray \*\* Removed obsolete EntityArray \*\* Removed obsolete ComponentGroupArray
  • \####ScriptBehaviourManager removal
  • The ScriptBehaviourManager class has been removed.
  • ComponentSystem and JobComponentSystem remain as system base classes (with a common ComponentSystemBase class)
  • - ComponentSystems have overridable methods OnCreateManager and OnDestroyManager. These have been renamed to OnCreate and OnDestroy.
  • - This is NOT handled by the obsolete API updater and will need to be done manually.
  • - The old OnCreateManager/OnDestroyManager will continue to work temporarily, but will print a warning if a system contains them.
  • World APIs have been updated as follows:
  • - CreateManager, GetOrCreateManager, GetExistingManager, DestroyManager, BehaviourManagers have been renamed to CreateSystem, GetOrCreateSystem, GetExistingSystem, DestroySystem, Systems.
  • - These should be handled by the obsolete API updater.
  • - EntityManager is no longer accessed via GetExistingManager. There is now a property directly on World: World.EntityManager.
  • - This is NOT handled by the obsolete API updater and will need to be done manually.
  • - Searching and replacing Manager should locate the right spots. For example, world.GetExistingManager() should become just world.EntityManager.
  • #### IJobProcessComponentData renamed to IJobForeach
  • This rename unfortunately cannot be handled by the obsolete API updater. A global search and replace of IJobProcessComponentData to IJobForEach should be sufficient.
  • #### ComponentGroup renamed to EntityQuery
  • ComponentGroup has been renamed to EntityQuery to better represent what it does. All APIs that refer to ComponentGroup have been changed to refer to EntityQuery in their name, e.g. CreateEntityQuery, GetEntityQuery, etc.
  • #### EntityArchetypeQuery renamed to EntityQueryDesc
  • EntityArchetypeQuery has been renamed to EntityQueryDesc

🔄 Changes

  • Minimum required Unity version is now 2019.1.0b9
  • Adding components to entities that already have them is now properly ignored in the cases where no data would be overwritten.
  • UNITY\_CSHARP\_TINY is now NET\_DOTS to match our other NET\_\* defines

🔧 Bug Fixes

  • Fixed exception in inspector when Script is missing
  • The presence of chunk components could lead to corruption of the entity remapping during deserialization of SubScene sections.
  • Fix for an issue causing filtering with IJobForEachWithEntity to try to access entities outside of the range of the group it was scheduled with.
