Okay, the issue with doing it by families is that if I put those 3 objects into a family, the distance of each corresponds to moving 3 different objects. The game uses a 2D map to create fake 3D ala Doom, so what it has to do is order Planet1, Planet2, and Planet3, then move Planet1vis, Planet2vis, and Planet3vis to the correct layers.
Sorry if that doesn't make much sense, if I had known what I do now now I'd do it differently but it's not having performance issues, and I don't have to expand on it later so I'd rather not go through 80+ events to make everything choose and use the right instances of different things.
Here's a test build of the game as-is

So the game has to put the closest planets on top so they overlap the others.
