Request: Optional Components in IJobProcessComponentData

IJobProcessComponentData should support optional components. In the generic arguments, they would have to be wrapped in a struct of some kind. In the execute method, you could just check if it exists before using it. It could be something like this:

Code (CSharp):

1. struct Job : IJobProcessComponentData<Optional<Position>> {
2.     public void Execute(<Optional<Position>> c0) {
3.         if (c0.exists)
4.             c0.x += 10;
5.     }
6. }

 

Just use ComponentDataFromEntity<Position>

which has an Exists(entity) method

 

That requires more code. Considering how difficult it is to reuse code on jobs due to them being structs, I think we should reduce boilerplate as much as possible.
