Entity Particle System

What method if any to add a Particle System Game Object to an Entity Bullet.
Previously when using Game Objects I would just make the Particle System a child of the moving bullet to add a particle effect.
I have been experimenting but without success.
Thanks

 

Code (CSharp):

1. entityManager.AddComponentObject(entity, particleSystem);
2. entityManager.AddComponentData(entity, new CopyTransformToGameObject { });

 

I am pretty newbie so not sure how to implement this.
I was using IConvertGameObjectToEntity and it wont add the particle system to my prefab bullet entity.
I can add it to a bullet in the scene but I need the particle to be in sync with the entity positions for all instances as they travel.

 

the way i see it:

1) spawning Projectiles Entities with EffectID CD.

2) a LinkPrefabsSystem (ComponentSystem) tracks all entities with EffectID but without EffectIDSystemState and get the required Prefab from pool otherwise instantiate a new one.

the correct way to link a transform to an Entity, (make sure your entity has the LocalToWorld cd)

Code (CSharp):

1.  
2. GameObject BulletPrefab; // a normal gameObject from Pool
3. entityManager.AddComponentObject(ProjectileEntity, BulletPrefab.transform);
4. entityManager.AddComponentData(ProjectileEntity, new CopyTransformToGameObject { });
5.  

3) the ProjectileEntity do it's job and get destroyed.

4) a RecyclePrefabsSystem (ComponentSystem) tracks all entities with EffectIDSystemState but without EffectID,
* recycle the prefab used,
* removes the EffectIDSystemState
* destroyes the ProjectileEntity .
