    I am currently passing an int counter into a job inside of a NativeArray so that the value can be set in the job then read back after the job is completed.

    Is there a cleaner way to do this?

    I ran into a similar issues but never thought of using a native array as a work around.

    I'm not sure how that helps me - I am completing the job already.

    I can pass it in by value like 'int counter' and it will write to a copied value in the job or I can do the hack I'm currently doing and pass it in by 'NativeArray<int> counter' which is set to just size of 1 and contains the counter value so I can set by reference and then read the value back outside the job.

    I am sorry, I misread the question... NativeArray is one way. int* is another. NativeArray is more robust / safety system.

    int* is more efficient but easy to make mistake and cause crashes with, when you don't have a full understanding of how GC & stack works.

    We should probably introduce NativeValue for this purpose...

    That sounds good.

    It's encouraging to see the CTO being so hands-on with the tech.
