Putting linked archetypes closer together

Hey, I'm using two Components that work in tandem with each other (ShieldTile and Shieldable) but sit on different Entities.

Most of the Time, I'm just trying to fetch the Shieldable Data via GetComponent while being in a ShieldTile.ForEach. So my question is, is that alright? is there a better way to do it, or would it, indeed, be nice if we could position those Entities (or their Chunks) in an A-B-A-B order, because fetching that Data would be faster?

 

I don't know enough about your problem to make a suggestion for optimal data layout. But what exactly would you expect the A-B-A-B data structure to look like?

 

I wouldn't know^^ But I thought since data layout might at least be placed 2 dimensional a column is populated with Entities A and its linked Entities are placed at the next column

 

Memory is one-dimensional.
A chunk is composed of an array of entities, and an array of each component in the archetype, plus metadata, shared component indices, and chunk components.
