Question How to add an Aspect to an Entity

Hey, im looking into Aspects for the first time, but i can not get any of my Aspects to show up in the Inspector.
(Unity 2022.2.7f1, Entities 1.0.0-pre.44)

e.g. if i create a simple example-aspect

Code (CSharp):

1. using Unity.Entities;
2. using Unity.Transforms;
3.  
4. public readonly partial struct TestAspect : IAspect
5. {
6.     readonly RefRO<LocalTransform> tr;
7. }

i woul expect basically every Entitie (all my Entities have Local Transforms) to have this Aspect. But only the TransformAspect (and for Entities with Colliders the ColliderAspect) show up in the Inspector.
Do i have to do something special, to add an Aspect? What am i missing?

Thanks for help in advance!

 

I don't know if this is a bug. Had the same issue, and every time I tried to check out if my aspect was showing in the Aspects list my unity editor ended up crashing a little while later. I think it's probably something that will be fixed in the near future (I hope).

 

Thanks for your answer. I also thought it might be a Bug. Maybe someone had the same issue and can share a workaround or a unity and ecs Version combination that should work?

 

I found a solution / the missing part in my code:

The Aspect must be in a namespace like this:

Code (CSharp):

1. using Unity.Entities;
2. using Unity.Transforms;
3.  
4. namespace MP.normal
5. {
6.     public readonly partial struct TestAspect : IAspect
7.     {
8.         readonly RefRO<LocalTransform> tr;
9.     }
10.  
11. }

I put all my Scripts in a namespace, and now the Aspects apear.

 

Thanks for the info. Im also gonna try that, since I am not using namespaces just like you.

 

That's a bug surely. Depends if Unity fix it though.

 

this fixes my error.
