Accessing all ISharedComponentData in jobified parallel fashion?

Hello,

I've made some forum posts on the post on this topic, but I'm worried things have changed with new APIs. How is this done now? I want to access look at/process ISharedComponentData in a parallel fashion.

Thanks.

This is an older forum post on the same topic. Not sure how this is done now.

 

Answer the same afaik. You can't operate on ISCD directly inside job. Only with ISCD index.

 

The data is not on the chunk header. SCD sharing mechanism is by distributing only an integer index. The integer index together with SCD type index gets the real data. But EntityManager is not here to utilize those in the job, plus job touching managed data would be bad for Burst and bad for safety as SCD can be anything.

I do hope there is a way to explicitly state that SCD is a value type and let those values be copied to each chunk (in some sense "shared" but not really) and use in-job. However all over the API ISharedComponentData isn't with `struct` type constraint.

But then we get close to chunk component in concept with that. Maybe you can try using that instead. (together with blob inside that chunk component, so it get as close to SCD as possible. chunk component = not on each entity, blob = shared + readonly) Though I am not sure how chunk component works when entity move around to an another chunk. It could be more messy than SCD. Never use it before.
