Overlapp AABB , error (Solved)

Im getting the following error while trying to execute overlapAABB :
ArgumentException : SliceStart + Length (7) range must be <= array.Length (5)

The full OnUpdate method (https://pastebin.com/DdwpnwZC)

Code (CSharp):

1.        
2.             NativeList<int> hitsIndices = new NativeList<int>(Allocator.Temp);
3.  
4.             CollisionFilter filter = new CollisionFilter
5.             {
6.                 BelongsTo = 3,
7.                 CollidesWith = 3,
8.                 GroupIndex = 0
9.             };
10.             //Check for nearby unitsgroup already existing
11.             Aabb aabb = new Aabb
12.             {
13.                 Min = translation.Value + new float3(-castRadius, 0, -castRadius),
14.                 Max = translation.Value + new float3(castRadius, 1, castRadius)
15.             };
16.             OverlapAabbInput overlapAabbInput = new OverlapAabbInput
17.             {
18.                 Aabb = aabb,
19.                 Filter = filter,
20.             };
21.  
22.             bool haveHits = collisionWorld.OverlapAabb(overlapAabbInput, ref hitsIndices);
23.  

 

Is it possible that some other system that was run after the physics step removed some of the bodies and that your collision world is not up to date with it? Collision world internally holds a hierarchy of bodies, so if the original body buffer changes, collision world needs to be rebuilt in order to "see" those changes...

 

Well i do instantiate new UnitsGroup(s) containing a collider but this occur after this system.

 

Yeah I'm mostly referring to stuff done during the physics step or before this system... Which physics version are you using?

 

Im using Unity physic 0.3.1.

 

Could it be that your system isn't scheduled properly, so it runs in parallel with the next physics step? All physics related systems should happen before EndFramePhysicsSystem, and you can ensure that by using UpdateBefore and also adding this system's handle to the EndFramePhysicsSystem.HandlesToWaitFor... Let me know if this changes anything.

 

Ok so i added the following decorators
"[UpdateBefore(typeof(EndFramePhysicsSystem)), UpdateAfter(typeof(StepPhysicsWorld))]" and added to the dependency the finalHandler of the BuildPhysicWorldSystem.

Code (CSharp):

1.         Dependency = JobHandle.CombineDependencies(Dependency, buildPhysicsWorld.FinalJobHandle);
2.         Dependency = JobHandle.CombineDependencies(Dependency, FindUnitsGroupInProximiyJobHandle);
3.         endSimulationEcbSystem.AddJobHandleForProducer(this.Dependency);

Everything seem to be working correctly thanks for the help!
