Class JobDependencyTracker Extends IAstarPooledObject

Public

Automatic dependency tracking for the Unity Job System.

Uses reflection to find the [ReadOnly] and [WriteOnly] attributes on job data struct fields. These are used to automatically figure out dependencies between jobs.

A job that reads from an array depends on the last job that wrote to that array. A job that writes to an array depends on the last job that wrote to the array as well as all jobs that read from the array.

struct ExampleJob : IJob {
public NativeArray<int> someData;

public void Execute () {
// Do something
}
}

void Start () {
var tracker = new JobDependencyTracker();
var data = new NativeArray<int>(100, Allocator.TempJob);
var job1 = new ExampleJob {
someData = data
}.Schedule(tracker);

var job2 = new ExampleJob {
someData = data
}.Schedule(tracker);

// job2 automatically depends on job1 because they both require read/write access to the data array
}
