Resolved How to check if it has a specific component in parallel job & [BurstCompile]

I want to check if the Entity returned by `RayCast()` has `GroundTag` or not.
I know I can check with `HasComponent<GroundTag>()` if it has an EntityManager, but I get an error when I pass state.EntityManager to IjobEntity.
I want to run this job with `ScheduleParallel()` and `[BurstCompile]`.

Unity.Entities : 1.0.10
Any help would be greatly appreciated.

Code (CSharp):

1.  
2. [BurstCompile]
3. [UpdateInGroup(typeof(PhysicsSystemGroup))]
4. [UpdateAfter(typeof(PhysicsSimulationGroup))]
5. public partial struct CheckGroundedSystem : ISystem
6. {
7.  
8.   [BurstCompile]
9.   public void OnUpdate(ref SystemState state)
10.   {
11.  
12.     new CheckGroundedJob
13.     {
14.       DeltaTime = SystemAPI.Time.DeltaTime,
15.       CollisionWorld = SystemAPI.GetSingleton<PhysicsWorldSingleton>().CollisionWorld,
16.     }.ScheduleParallel();
17.   }
18. }
19.  
20.  
21. [BurstCompile]
22. public partial struct CheckGroundedJob : IJobEntity
23. {
24.   public float DeltaTime;
25.   [ReadOnly] public CollisionWorld CollisionWorld;
26.  
27.   [BurstCompile]
28.   private void Execute(RefRO<LocalTransform> localTransform, RefRO<GroundingData> grounding, [EntityIndexInQuery] int sortKey)
29.   {
30.     float3 RayFrom = localTransform.ValueRO.Position - new float3(0, 1.1f, 0);
31.     float3 RayTo = localTransform.ValueRO.Position - new float3(0, 1.5f, 0);
32.     Entity entity = Raycast(RayFrom, RayTo, CollisionWorld);
33.     if (entity != Entity.Null)
34.     {
35.  
36.        //
37.        //  I want to check if the entity returned by
38.        //   `RayCast()` has `GroundTag` or not here!.
39.        //
40.  
41.     }
42.   }
43.  
44.   [BurstCompile]
45.   Entity Raycast(float3 RayFrom, float3 RayTo, CollisionWorld CollisionWorld)
46.   {
47.     RaycastInput input = new RaycastInput()
48.     {
49.       Start = RayFrom,
50.       End = RayTo,
51.       Filter = new CollisionFilter()
52.       {
53.         BelongsTo = ~0u,
54.         CollidesWith = ~0u, // all 1s, so all layers, collide with everything
55.         GroupIndex = 0
56.       }
57.     };
58.  
59.     RaycastHit hit = new RaycastHit();
60.     bool haveHit = CollisionWorld.CastRay(input, out hit);
61.     if (haveHit)
62.     {
63.       return hit.Entity;
64.     }
65.     else
66.     {
67.       return Entity.Null;
68.     }
69.   }
70. }

 

Self resolved.

// in IJobEntity

[ReadOnly] public ComponentLookup<GroundTag> GroundTagLookup;



// in ISyetem

GroundTagLookup = SystemAPI.GetComponentLookup<GroundTag>(true),



// execute() in IJobEntity.

GroundTagLookup.HasComponent(entity)

Thanks

 

Also, this content was ECS, not Physics.
My apologies.
