[GenerateAuthoringComponent] on IBufferElementData with non-serializable field

Code (CSharp):

1. using Unity.Entities;
2. using Unity.Mathematics;
3. using System;
4.  
5. [GenerateAuthoringComponent]
6. [Serializable]
7. public struct MyElement : IBufferElementData
8. {
9.     public half value;
10. }

When the authoring component is attached to GameObject, List<MyElement> doesn't show up in the inspector (which is the correct behaviour I guess, maybe not for math types though).
Converting the object results in the following:

NullReferenceException: Object reference not set to an instance of an object

Unity.Entities.Hybrid.BufferElementAuthoring`2[TBufferElementData,TWrappedValue].Convert (Unity.Entities.Entity entity, Unity.Entities.EntityManager destinationManager, GameObjectConversionSystem _) (at Library/PackageCache/com.unity.entities@0.8.0-preview.8/Unity.Entities.Hybrid/BufferElementDataAuthoringComponent.cs:20)

Which is happening due to the List<MyElement> being null because it was not set in the inspector as far as I can tell.

 

Hi, have you solved the problem, I'm having the same one and I do not know how to solve it.

 

Nope, in my case I switched to float instead of half for now.

 

Why not create your own authoring component instead of using a generated component with the attribute? For the authoring component, use a float with a range attribute to clamp its value within the range you need for runtime then in the conversion just cast the float into a half.
