I'm just starting out as a game dev, and I'm finding some difficulties at the time of naming classes. I usually call the one that handles everything World or Map, or Grid. Then there's the stuff inside... For example, I'm doing a frogger clone and I have a class for everything that moves on screen (I try to use MVC and I'm talking about the model here - I have Sprite classes in the view), I named it Object for lack of a better idea. Then there's a subclass from that which I named Frog (though I could name it Player) and another one for the things controlled by the computer... I don't know what to call that, it could be Enemy or Obstacle (appropriate for cars & trucks) but it also includes the turtles which are more like helpful objects yet not powerups? I also just learned what a hitbox is... is there a good resource out there specifically for learning all these things?
If you're having trouble naming things it's probably because your class design itself is messy. Just hearing you talk about your code it seems like you're overusing inheritance.
Also, there are a ton of questions on here about MVC and generally speaking it isn't a good pattern to try to force into things. Gaming is more like Model view viewmodel than mvc anyway.
I don't think there's a specific reference for what you're looking for. Also, in general SE sites are better if you ask specifically what you're looking for instead of a reference for what you're looking for. For example, draw out your specific class hierarchy and ask what might be the best way to name your obstacles-that-also-can-be-useful, or whatever.
