Unity ECS Lights

Hello Guys,

i want to use lights in ecs, but if i add the conversion script Convert to entity, there is no light.
Can anyone explain me how i get light in a pure ecs way or is now no way to implement lights in pure ecs?

 

I was asking this some time ago, the ECS team is aware of it and it's coming but right now, you'd have to spawn them yourself as gameobject which follows an entity. Pretty easy as it's just a matter of getting the followed entity translation and add some offset in a MonoBehaviour Update.

 

So the best way now is to add them as gameobjects and translate the transfrom in a system with the entity transform to the right position? I thought maybe i didnt notice something here for pure ecs way, thx for the reply.

 

Some hybrid solution can be good for now, to manipulate light GameObject. With mind for later change into pure, when option get available.

 

Omg so pumped for lights! My world is so dim without sweet sweet lights (pun intended). Really looking forward to seeing how many lights I can have flying around in lwrp!

 

I tested the new Package but get the following error if i add Convert To Entity: Convert and Destroy

NullReferenceException: Object reference not set to an instance of an object
Unity.Rendering.LightConversion.<OnUpdate>b__0_0 (UnityEngine.Light unityLight) (at Library/PackageCache/com.unity.rendering.hybrid@0.1.0-preview/Unity.Rendering.Hybrid/LightConversion.cs:46)


ok got it work, i'm dump and installed the High Definiton RP, so i removed it and it worked

 

Im try this code but with Lights dosnt work ;( This works only with objects with renderers

Code (CSharp):

1. private void Start()
2.     {
3.         List<Light> LTS = new List<Light>();
4.         var lights = FindObjectsOfType(typeof(Light));
5.         foreach(Object o in lights)
6.         {
7.             LTS.Add((Light)o);
8.         }
9.  
10.          EntityManager entityManager = World.Active.EntityManager;
11.         EntityArchetype entityArchetype = entityManager.CreateArchetype
12.                 (
13.                 typeof(Translation),
14.                 typeof(Rotation),
15.                 typeof(NonUniformScale),
16.                 typeof(LightComponent),
17.                 typeof(Light)
18.                 );
19.  
20.         entities = new NativeArray<Entity>(LTS.Count, Allocator.Temp);
21.         entityManager.CreateEntity(entityArchetype, entities);
22.  
23.  
24.  
25.         for (int i = 0; i < entities.Length; i++)
26.         {
27.             Entity entity = entities[i];
28.             entityManager.SetComponentData(entity, new Translation { Value = new float3(LTS[i].gameObject.transform.position.x, LTS[i].gameObject.transform.position.y, LTS[i].gameObject.transform.position.z) });
29.             entityManager.SetComponentData(entity, new Rotation { Value = new Quaternion(LTS[i].gameObject.transform.rotation.x, LTS[i].gameObject.transform.rotation.y, LTS[i].gameObject.transform.rotation.z, LTS[i].gameObject.transform.rotation.w) });
30.             entityManager.SetComponentData(entity, new NonUniformScale { Value = new float3(LTS[i].gameObject.transform.localScale.x, LTS[i].gameObject.transform.localScale.y, LTS[i].gameObject.transform.localScale.z) });
31.  
32.             entityManager.SetComponentData(entity, new LightComponent
33.             {
34.                 type = LTS[i].type,
35.                 range = LTS[i].range,
36.                 spotAngle = LTS[i].spotAngle,
37.                 color = LTS[i].color,
38.                 intensity = LTS[i].intensity,
39.                 renderingLayerMask = LTS[i].renderingLayerMask,
40.                 cullingMask = LTS[i].cullingMask,
41.             });
42.         };
43.  
44.         entities.Dispose();
45.  
46.         foreach (Light o in LTS)
47.         {
48.             o.enabled = false;
49.         }
50.     }
