After running,I can see a entity in Entities Hierarchy which have Local Transform,Local To World and Render Mesh.The Scale of Local Transform is 3 and The Mesh and Material is not Null. I also create a GameObject with same Material and Mesh then I can see the model correctly.
Codes show below:
using UnityEngine;
using Unity.Entities;
using Unity.Transforms;
using Unity.Collections;
using Unity.Rendering;
public class NewBehaviourScript : MonoBehaviour
{
// Start is called before the first frame update
[SerializeField] private Mesh mesh;
[SerializeField] private Material material;
void Start()
{
EntityManager entityManager = World.DefaultGameObjectInjectionWorld.EntityManager;
EntityArchetype entityArchetype = entityManager.CreateArchetype( typeof(LocalTransform),typeof(RenderMesh),typeof(LocalToWorld));
//Entity entity= entityManager.CreateEntity(entityArchetype);
NativeArray<Entity> entityArray = new NativeArray<Entity>(1, Allocator.Temp);
entityManager.CreateEntity(entityArchetype, entityArray);
//entityManager.SetComponentData(entity,new levelComponent{level =114514});
for (int i = 0; i < entityArray.Length; i++)
{
Entity entity = entityArray[i];
entityManager.SetComponentData(entity,new LocalTransform(){Scale = 3});
entityManager.SetSharedComponentManaged(entity,new RenderMesh() {mesh = mesh,material = material});
}
entityArray.Dispose();
}
}
