全局唯一组件，修改数值后不会产生新的组件，而是全部实体的块组件内容都同步变化。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Unity.Entities;
public struct MyChunkComponentData : IComponentData
{
    public int num;
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Unity.Entities;
public class ChunkTest : MonoBehaviour
{
    private void Start()
    {
        EntityManager entityManager = World.DefaultGameObjectInjectionWorld.EntityManager;
        //创建Chunk类型
        EntityArchetype type = entityManager.CreateArchetype(ComponentType.ChunkComponent(typeof(MyChunkComponentData)));
        //创建Chunk实体1
        Entity chunkEntity = entityManager.CreateEntity(type);
        //创建Chunk实体2
        Entity chunkEntity2 = entityManager.CreateEntity(type);
        //获取实体1的Chunk类对象
        ArchetypeChunk chunk = entityManager.GetChunk(chunkEntity);
        //修改Chunk值
        entityManager.SetChunkComponentData(chunk, new MyChunkComponentData() { num = 10 });
    }
}
