Question by Tomas_Otto · Aug 21, 2020 at 12:17 PM · componentsdots

Class as a member of IComponentData struct?

Hello, I want to put a simple class into IComponentData struct but unity tells me it is not either primitive or blittable - can I do something about this?

An IComponentData implementation must be a struct and can only contain unmanaged, blittable types, including:

  • C#-defined blittable types

  • bool

  • char

  • (a fixed-sized character buffer)

  • BlobAssetReference (a reference to a Blob data structure)

  • fixed arrays (in an unsafe context)

  • structs containing these unmanaged, blittable fields

You may want to define simple class and provide some reasoning behind it.
