NavMeshWorld cannot be used in a job

I can't instantiate NavmeshQuery inside a ForEach. Here's the code

Code (CSharp):

1. Entities
2.                .WithName("Calculating_path")
3.                .WithAll<BehaviorProgressComponent>()
4.                .WithReadOnly(translation)
5.                .ForEach((Entity condition, int entityInQueryIndex, ref DynamicBuffer<ValidPathWaypointComponent> waypoints, ref BehaviorResultComponent result, in ValidPathQueryComponent query, in ValidPathPositionComponent position) =>
6.                {
7.                    var pathfinder = new NavMeshQuery(navMeshWorld, Allocator.Temp, NODE_ALLOCATION_AMOUNT);
8.                })
9.                .WithBurst()
10.                .Schedule();

The error messages are

But if I try doing this

Code (CSharp):

1. .WithNativeDisableUnsafePtrRestriction(navMeshWorld)

It doesn't work since NavMeshWorld itself is not a pointer, but the world inside of it is

 

there is a workaround which involves instantiating navMeshQueries in a system NativeArray at creation and access that array using the nativeThreadIndex for parallel safety (credit to reese schultz for finding this). you can check out reese repository for more implementation details : https://github.com/reeseschultz/ReeseUnityDemos/tree/master/Assets/Scripts/Path
