Frent v0.5.7-beta

Sparse Components!

• Just implement ISparseComponent on a component, and Frent will store it in sparse sets rather than archetypes.
• Entity.ArchetypicalComponentTypes api returns an array of all ComponentIDs on an entity that are not sparse.
• Entity.ComponentTypes will return an array of all ComponentIDs on an entity, and may allocate if a sparse component is present.
• Entity can be used in a foreach loop to get all ComponentIDs without allocating.
• WorldMarshal.GetSparseSet<T> to get raw sparse set data.

Frent v0.5.6-beta

Changes

• #8 Added Entity.AddFromHandles(params ReadOnlySpan<ComponentHandle>) api.
• #8 Added World.CreateFromHandles(ReadOnlySpan<ComponentHandle> componentHandles, ReadOnlySpan<TagID> tags = default); api.
• #17 New MultithreadUpdateTypeAttribute class. Filter attributes that inherit this class will be multithreaded when called in a World.Update method.
• #15 Multiple component update interfaces!
  • A component can now implement multiple component update interfaces.
  • Update methods can have more than one filter attribute as well.
  • The interface types must be different; the same interface cannot be implemented twice.

Breaking Changes

• New builder style query syntax.

Bug Fixes

• #13: World.Dispose now calls the destroyer on components.
• #12: Entity.AddAs now properly invokes component events.
• Fix issue with source generation on unity.

Frent v0.5.5.1-beta

Changes

• Complete internal refactoring of the source generator
  • Source generator now supports inner types, private inner types, and unbound generic interface components.
  • New diagnostics for some non-partial components and components that implement multiple component interfaces.
• World.UpdateComponent(ComponentID) for updating all entities with a specific component type.
• Entity creation during world updates fully supported.
  • You can create entities during world updates and call entity methods like Get<T> immediately.
  • Minimal performance penalty for creating components during world updates - usually not even a component copy.

Breaking Changes

• DeferredCreate is no longer present on entities created during a world update, as it is no longer needed.

Bug Fixes

• Fixed optimization with archetype traversal when using non-generic entity methods.
• Fix IndexOfOutRangeException in query enumerator
• Fix bug with premature ID recycling with component handles.
• Fix issue with component flags and versioning with traversing archetypes.
• Fix issue with the last component not being copies in World.CreateFromObjects().
