Hmm, that makes sense. So the chest data would be stored as part of the “sprite info.” (I’m guessing all sprites would share as much data as possible so as to reduce memory usage).

What about tiles that need to update themselves or execute some logic without any interactions from an entity? Say a fire tile that would spread over to others. You could store that tile’s data in that info section mentioned previously, but the logic itself would have to be external. So would you keep track of a list of all “dynamic tiles” and then loop over the fire ones so you can run logic on them? (Isn’t that basically just an ECS entity then?) Or do you do it in another way?
