So hey i have the following depreciated dots code and im not certain how do i convert it to the new dots system.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Unity.Entities;
using static Terrain;
using System.Diagnostics;

public class OnEntityAssign : MonoBehaviour ,IConvertGameObjectToEntity
{
    private Entity entity;
    private EntityManager entityManager;
   
    public PathIndex pathIndex;

    public void Convert(Entity entity, EntityManager dstManager, GameObjectConversionSystem conversionSystem)
    {
        this.entity = entity;
        this.entityManager = dstManager;
        dstManager.AddBuffer<PathBuffer>(entity);
    }

    public Entity GetEntity()
    {
        return entity;
    }

    public EntityManager GetEntityManager()
    {
        return entityManager;
    }

    public PathIndex GetPathIndex()
    {
        return entityManager.GetComponentData<PathIndex>(entity);
    }

    public DynamicBuffer<PathBuffer> GetPathBuffer()
    {
        return entityManager.GetBuffer<PathBuffer>(entity);

    }

    public void SetComponentData(PathIndex pathIndex)
    {
        entityManager.SetComponentData(entity, pathIndex);
    }

    public void EnityConvert()
    {
        //this.gameObject.AddComponent<ConvertToEntity>();
    }
}

First things first, everything that is public needs to be made nonpublic (except for Convert). Bakers don’t really have a way to communicate with each other. And MonoBehaviours need to be treated as readonly data.

(Oh boy am I glad they changed to the Baker workflow, this looks awful)

So if anybody is curious here is how i rewrote and it works now so neat :slight_smile:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Unity.Entities;
using static Terrain;
using System.Diagnostics;

public struct OnEntityAssign : IComponentData
{
    public Entity entity;

    public Entity GetEntity()
    {
        return entity;
    }

    public EntityManager GetEntityManager()
    {
        return World.DefaultGameObjectInjectionWorld.EntityManager;
    }

    public PathIndex GetPathIndex()
    {
        return GetEntityManager().GetComponentData<PathIndex>(GetEntity());
    }

    public void InitBuffer()
    {
        GetEntityManager().AddBuffer<PathBuffer>(GetEntity());
    }

    public DynamicBuffer<PathBuffer> GetPathBuffer()
    {
        return GetEntityManager().GetBuffer<PathBuffer>(GetEntity());
    }

    public void SetComponentData(PathIndex pathIndex)
    {
        GetEntityManager().SetComponentData(GetEntity(), pathIndex);
    }
}

and the baker:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Unity.Entities;

public class OnEntityAuthoring : MonoBehaviour
{
    public int id;
}

public class OnEntityAssignBaker : Baker<OnEntityAuthoring>
{
    public override void Bake(OnEntityAuthoring authoring)
    {
        var entityy = GetEntity(TransformUsageFlags.Dynamic);
        AddComponent(entityy, new OnEntityAssign
        {
            entity = entityy,
        });
    }
}
