Three structure types

It looks like the way I'm programming is reaching some kind of goal with how I'm now using three types of "structures" to manage a large scale project. First is type-style class, a small class with often only one variable, or something like Point or Rectangle classes. Creating your own types should be a priority in object-oriented programming anyway so I'm creating them when it makes sense. Which is almost always over using regular types. A great example is Point class, it's way better to create a class that holds x and y variables rather than use them as integers.

Second type is a regular class, not a type class but larger with more data and components. These are things like monster, item and level classes.

Third type is a procedure, which in C++ is just a function outside any class. Somehow I find these really useful in parts where you need some kind of action with object instances.

With these it feels like nothing is missing and I'm able to manage the source code better than ever before. Also, I've largely began to disconnect classes from "modular" files. I find that modules are useful, but only when you have a small class hierarchy (inheritance) or similar types of classes. For example I have Point, Coords, Rectangle and some other similar classes in one file, because they inherit from each other. You need to include the base classes anyway if you want to use any of them.
