I read on this thread that ECB is now supported by Burst. I can't get that to work. I'm currently working on 2019.3.0f1. For instance, Code (CSharp): CommandBuffer.SetComponent(index, Entities[index], new Translation { Value = new float3(worldPosition.x, worldPosition.y, RootPosition.z) }); Generates the following errors : I'm trying to set a few components, along with a DynamicBuffer. Everything produces errors when [Burst] is enabled. Any idea what's wrong?
