Laser groups of 1/2/3/4, how does ECS/DOTS handle children?

So in my normal mode of gameobjects, I have 4 different prefabs of lasers. Each prefab holds a group of lasers 1/2/3/4. Each laser has a rigid body to collision detect itself while the other up to 3 lasers have their own individual colliders.

If ECS/DOTS had children,

After conversion to entity of a laser group, I could access children by transform.GetChild(x) to place on physics shape/body. But I am unable to get the child of an ECS entity. How do I do that?

Is it possible I make new prefabs with laser having shape/body on them? Cuz that would solve it too.

Thanks,
Jim

 

There's a buffer called Child with all of an entities children.

 

Ty you very much Mr. Carvey.

 

Lets say I'm in a MonoBehaviour, IConvertGameObjectToEntity

where I have both the gameObject and entity reference at this point.

How do I access said buffer with entity?

Ty, the documentation online is poor. I'm thankful for the community

No Solution found yet.

 

It’s probably easiest to add a new ComponentData or add to an existing ComponentData a field that holds a reference to the entities you are interested. During conversion you can get a reference to the entity linked to a child GameObject and store that. When the entity Prefab is instantiated ECS will remap the prefab entity reference to an instance reference.

 

I suggest you look into DynamicBuffer keywords. Plenty discussions and examples on the forum.
Also, please check dots samples on the git. It is rich source of knowledge.
