Resolved Is "PhysicsCollider" of "Null BlobAssetReference" still supported?

In documents, syas it is possible to create a Collider which has a null BlobAssetReference. However in current physics 6.0, there is an error occurred at

if (collider.Value.Value.Type == ColliderType.Compound)

of method

CheckColliderFilterIntegrity(NativeArray<PhysicsCollider> colliders)

in system

ExportPhysicsWorld

.
My Code is

Code (CSharp):

1.  
2.             Entities.WithBurst().WithAll<TopologyComp>().WithNone<PhysicsCollider>().ForEach((Entity topoEntity) => {
3.                 ecb.AddComponent(topoEntity, new PhysicsCollider { Value = BlobAssetReference<Collider>.Null });
4.                 ecb.AddComponent(topoEntity, new PhysicsVelocity { });
5.                 ecb.AddComponent(topoEntity, PhysicsMass.CreateKinematic(MassProperties.UnitSphere));
6.                 ecb.AddComponent(topoEntity, new PhysicsDamping { Angular = .05f, Linear = .01f });
7.             }).Schedule();

So, what's wrong with my code, or the null blobassetreference is no longer supported?

 

Hi @BobFlame , thank you for reporting this! Sorry for the inconvenience, that's a bug and we'll fix it.

In the meantime, you can make UnityPhysics a local package (see the thread about that) and change the condition to be:

if (collider.IsValid && collider.Value.Value.Type == ColliderType.Compound)

 

Thx

 

Thank you for the work around. We still have to do this for new projects, any update for the physics package any time soon?

 

Hi，original post‘s problem is due to making compounding collider with some child collider is null, while it is not stated as valid from unity doc. What is valid is using physicscollider with null value. So what problem have you encountered?

 

Thank you for coming back to the thread, BobFlame.

I make an archetype with an empty physicscollider:

Code (CSharp):

1.         public static EntityArchetype playerArchetype = manager.CreateArchetype(
2.             typeof(RenderMesh), typeof(LocalToWorld), typeof(Translation), typeof(Rotation), typeof(PhysicsCollider),
3.             typeof(PerInstanceCullingTag), typeof(WorldToLocal_Tag), typeof(Player) );
4.  

 

Sorry I don't use archetype much, I don't get which value is null. You are creating an archetype with a group of types, no instance value is involved.
