Bug CompoundCollider Children Not Working Correctly

Iterating over a compound colliders children gives bad values e.g. saying collider is terrain and showing seemingly "random" values for filter. I've tried with both using foreach and for looping.

Code (CSharp):

1. var physicsColliderPtr = intCollider.ColliderPtr;
2. var newFilter = new CollisionFilter()
3. {
4.     BelongsTo = filterInterior.belongsTo.Value << spaceShipData.crewGameID,
5.     CollidesWith = filterInterior.collidesWith.Value << spaceShipData.crewGameID,
6.     GroupIndex = 0
7. };
8.  
9. if (physicsColliderPtr->Type == ColliderType.Compound)
10. {
11.     var compoundCollider = (CompoundCollider*)physicsColliderPtr;
12.     compoundCollider->Filter = newFilter;
13.     SetChildFilter(ref newFilter, ref compoundCollider);
14. }
15.  
16. ...
17.  
18. unsafe void SetChildFilter(ref CollisionFilter collisionFilter, ref CompoundCollider* collider)
19. {
20.     var numChildren = collider->NumChildren;
21.     for (int i = 0; i < numChildren; i++)
22.     {
23.         ref var child = ref collider->Children[i];
24.        ...
25.  
26.     }
27. }

 

Same problem, please fix asap.

 

I solved my case by creating an GameObjectConversionSystem in GameObjectAfterConversionGroup update group that clones and store the colliders in a IBufferElementData that is later used to set the correct collider when needed. Hope it helps : )

Spoiler: Some code

Code (CSharp):

1.     [UpdateInGroup(typeof(GameObjectAfterConversionGroup ))]
2.     public class MultiLayerPhysicsCollidersConversionSystem : GameObjectConversionSystem
3.     {
4.         protected override void OnUpdate()
5.         {
6.             Entities.ForEach((MultiLayerColliderAuthoring multiLayerColliderAuthoring) =>
7.             {
8.                 var entity = GetPrimaryEntity(multiLayerColliderAuthoring.gameObject);
9.                 if (DstEntityManager.HasComponent<PhysicsCollider>(entity))
10.                 {
11.                     var collider = DstEntityManager.GetComponentData<PhysicsCollider>(entity);
12.                     var multiLayerPhysicsColliderBuffer = DstEntityManager.GetBuffer<MultiLayerColliderElementData>(entity);
13.                  
14.                     // 0 is world default
15.                     multiLayerPhysicsColliderBuffer.Add(new MultiLayerColliderElementData() {Value = collider.Value});
16.                     var colSettings = CollisionSettings.GetOrCreate();
17.                  
18.                     // TODO should probably be checked vs the blobassetstore for similar blobassets
19.                    
20.                     // Create clone for each layer
21.                     for (int i = 0; i < MultiLayerColliderAuthoring.numShips; i++)
22.                     {
23.                         var colliderBlobPtr = collider.Value.Value.Clone();
24.                         multiLayerPhysicsColliderBuffer.Add(new MultiLayerColliderElementData() { Value = colliderBlobPtr});
25.  
26.                         colliderBlobPtr.Value.Filter = new CollisionFilter()
27.                         {
28.                             BelongsTo = colSettings.interiorStartCollisionTag.Value << (i),
29.                             CollidesWith = colSettings.interiorStartCollisionTag.Value << (i),
30.                             GroupIndex = 0,
31.                         };
32.                     }
33.                 }
34.             });
35.         }
36.     }
