Unity Compatibility

Minimum Unity: 2020.3 (0f1)

Package Dependencies

✨ Features

  • `Native/UnsafeList*.RemoveRange*` with index/count arguments.
  • Upgraded to burst 1.5.2
  • `UnsafeText` added.

📈 Improvements

  • Burst compatibility tests now treat any explicit uses of `[BurstCompatible]` on private methods as an error (as opposed to silently ignoring) to avoid giving the impression that private methods are being tested.
  • `NativeList` generic constraint `T` is changed from `struct` to `unmanaged` to match `UnsafeList`. User code can be simply fixed by changing `struct` to `unmanaged` when using `NativeList` inside generic container.
  • `NativeHashMap.GetBucketData` renamed to `NativeHashMap.GetUnsafeBucketData`
  • Update the package to 1.0.0
  • `HeapString` renamed to `NativeText`. `NativeText` is based on `UnsafeText`.
  • ### Deprecated
  • Generated `FixedList[Byte/Int/Float][32/64/128/256/512]` are deprecated, and replaced with generics `FixedList[32/64/128/256/512]`.
  • `UnsafeMultiHashMap.GetUniqueKeyArray` replaced with extension method `UnsafeMultiHashMap.GetUniqueKeyValueNBC` from `Unity.Collections.NotBurstCompatible` namespace.
  • `NativeMultiHashMap.GetUniqueKeyArray` replaced with extension method `NativeMultiHashMap.GetUniqueKeyValueNBC` from `Unity.Collections.NotBurstCompatible` namespace.
  • `NativeList.ToArray` replaced with extension method `NativeList.ToArrayNBC` from `Unity.Collections.NotBurstCompatible`
  • `NativeList.CopyFrom` replaced with extension method `NativeList.CopyFromNBC` from `Unity.Collections.NotBurstCompatible` namespace.
  • `UnsafeAppendBuffer.Add` replaced with extension method`UnsafeAppendBuffer.AddNBC` from `Unity.Collections.LowLevel.Unsafe.NotBurstCompatible` namespace.
  • `UnsafeAppendBuffer.ToBytes` replaced with extension method `UnsafeAppendBuffer.ToBytesNBC` from `Unity.Collections.LowLevel.Unsafe.NotBurstCompatible` namespace.
  • `UnsafeAppendBuffer.Reader.ReadNext` replaced with extension method `UnsafeAppendBuffer.Reader.ReadNextNBC` from `Unity.Collections.LowLevel.Unsafe.NotBurstCompatible` namespace.
  • `Native/UnsafeList*.RemoveRange*WithBeginEnd` methods with begin/end arguments in favor of `Native/UnsafeList*.RemoveRange*` with index/count arguments.
  • `UnsafeList` and replaced it with `UnsafeList`.
  • VirtualMemoryUtility.

⚡ API Changes

  • `NativeQueue.PersistentMemoryBlockCount` and `NativeQueue.MemoryBlockSize` are now internal APIs.

🔧 Bug Fixes

  • Burst compatibility tests will now ignore any method containing a '$' in the name, which can be generated by the Burst direct call IL post processor.
  • xxHash3 is initialized after assembly load to avoid an exception that could be thrown if xxHash3 is accessed for the first time on a thread other than the main thread.
