Question How to use AddJobHandleForProducer() in burst compiled ISystem

I'm struggling figure out how to use EntityCommandBufferSystem.AddJobHandleForProducer() from within an ISystem that is burst compiled.

I'm creating Entity Command Buffers like so:

var singleton = SystemAPI.GetSingleton<EndSimulationEntityCommandBufferSystem.Singleton>();
var ecb = singleton.CreateCommandBuffer( state.WorldUnmanaged );

... and passing ecb into a job.

But it doesn't seem like there's any way to get a reference to the EntityCommandBufferSystem itself since it's a managed system.

So, how do we register the JobHandle as a dependency of the ECB system?

 

You dont need to, with getting the singleton now.

 

Thanks, great to know—is this documented somewhere officially?

 

It's not documented. In fact, the documentation states the opposite.
