Question by twDuke · Aug 08, 2019 at 06:36 PM · renderingdots

How do I create entities from an archtype that are renderable

Hello,

Im playing around with the new DOTS packages.

One thing i have not managed to do is use an archtype to create an entity that is visible in the scene. This is what I have so far, I can see the entities being created in the entity debugger, but they are not rendered. Any help is appreciated. I guess i'm missing some component on the archtype.

 using Unity.Entities;
 using Unity.Mathematics;
 using Unity.Transforms;
 using UnityEngine;
 
 public class CreateStuff : MonoBehaviour
 {
     public int CountX = 100;
     public int CountY = 100;
 
     void Start()
     {
         var entityManager = World.Active.EntityManager;
         var archetype = entityManager.CreateArchetype(typeof(Translation), typeof(Scale), typeof(Rotation), typeof(MeshRenderer), typeof(MeshFilter));
         for (int x = 0; x < CountX; x++)
         {
             for (int y = 0; y < CountY; y++)
             {
                 var instance = entityManager.CreateEntity(archetype);
                 var position = transform.TransformPoint(new float3(x - CountX / 2, noise.cnoise(new float2(x, y) * 0.21F) * 10, y - CountY / 2));
                 entityManager.SetComponentData(instance, new Translation() { Value = position });
                 entityManager.SetComponentData(instance, new Scale() { Value = 1 });
             }
         }
     }
 }
