How to use RigidBodyIndex in a job?

When I use the PhysicsWorld.GetRigidBodyIndex in job.There are a
ArgumentException: Slice may not be used on a restricted range array Parameter name: array
Unity.Collections.NativeSlice`1[T]..ctor (Unity.Collections.NativeArray`1[T] array, System.Int32 start, System.Int32 length) (at C:/buildslave/unity/build/Runtime/Export/NativeArray/NativeSlice.cs:105)
Unity.Physics.CollisionWorld.get_Bodies () (at Library/PackageCache/com.unity.physics@0.2.2-preview/Unity.Physics/Collision/World/CollisionWorld.cs:19)
Unity.Physics.PhysicsWorld.get_Bodies () (at Library/PackageCache/com.unity.physics@0.2.2-preview/Unity.Physics/Dynamics/World/PhysicsWorld.cs:18)
Unity.Physics.Extensions.PhysicsWorldExtensions.GetRigidBodyIndex (Unity.Physics.PhysicsWorld& world, Unity.Entities.Entity entity) (at Library/PackageCache/com.unity.physics@0.2.2-preview/Unity.Physics/Extensions/World/PhysicsWorldExtensions.cs:13)
EngineSystem+EngineJob.Execute (EngineData& engineData) (at Assets/_Scripts/EngineSystem.cs:37)

the EngineSystem.cs:37 is"int rigidBodyIndex = physicsWorld.GetRigidBodyIndex(engineData.Entity);"

Any and all help will be appreciated.

Code (CSharp):

1. public class EngineSystem : JobComponentSystem
2. {
3.     IGetInput input;
4.  
5.     BuildPhysicsWorld m_BuildPhysicsWorldSystem;
6.  
7.     protected override void OnStartRunning()
8.     {
9.         input = Manager_Input.instance.input;
10.     }
11.  
12.     protected override void OnCreate()
13.     {
14.         m_BuildPhysicsWorldSystem = World.Active.GetOrCreateSystem<BuildPhysicsWorld>();
15.     }
16.  
17.     [BurstCompile]
18.     struct EngineJob : IJobForEach<EngineData>
19.     {
20.         public PhysicsWorld physicsWorld;
21.  
22.         public void Execute([ReadOnly]ref EngineData engineData)
23.         {
24.             int rigidBodyIndex = physicsWorld.GetRigidBodyIndex(engineData.Entity);
25.             physicsWorld.ApplyImpulse(rigidBodyIndex, engineData.Impule, engineData.Point);
26.         }
27.     }
28.  
29.     protected override JobHandle OnUpdate(JobHandle inputDeps)
30.     {
31.         if (!input.DoingTest) return inputDeps;
32.         inputDeps = JobHandle.CombineDependencies(inputDeps, m_BuildPhysicsWorldSystem.FinalJobHandle);
33.         var physicsWorld = m_BuildPhysicsWorldSystem.PhysicsWorld;
34.         var handle = new EngineJob
35.         {
36.             physicsWorld = physicsWorld
37.         }.Schedule(this, inputDeps);
38.         handle.Complete();
39.         return handle;
40.     }
41. }
42.  
43. public struct EngineData : IComponentData
44. {
45.     public Entity Entity;
46.     public float3 Impule;
47.     public float3 Point;
48. }

 

Did you ever find out the syntax to use RigidBodyIndex properly? I am getting a slightly different error but believe it is from not passing in an array of hits using the RigidBodyIndex. This syntax is tricky and the docs are remit in giving even the basics of what something does. The CollisonEvent Execute works differently. No other refs or inoputs allowed except Execute(CollisionEvent collisionEvent) {//code}
