Is this... refactoring?

I think it is, but in a nice way. At least it doesn't feel that bad, and it's more like re-arranging the source code. The first step was actions as procedures, but it's also possible to create classes with an outlook at the basic data. For example today I programmed a look command to an external class Look. It takes in Level and Avatar (aka player) data and then determines different ways to look at things. The source code was largely previously both in Level and Avatar classes which increased their size and distributed functionality in lots of small member functions.

In comparison the Look class is focused and has only one public "entry point" function. This prevents confusion when you pass the data into class almost as if it was a procedure. From maintain perspective it's also easier, because when you need to fix something in looking you know where to find everything. Only low level routines are in Level and Player classes to return some atomic piece of data.

I don't know, maybe it took a good while to realize that actions should be detached from classes like Level to keep them simple, in cases where actions need two or more (large) classes in them. And also, that procedural style can be better in some situations which, undoubtebly, has been a troublesome concept for me to accept, since I have been such a fan and connoisseur of object-oriented programming.
