Beginning C++ Game Programming

Summary

In this chapter, we learned some new C++ concepts. First, Inheritance allows us to extend a class and gain all of its functionality. We also learned that we can declare variables as protected, and that will give the child class access to them, but they will still be encapsulated (hidden) from all other code.

We were also introduced to the concept of polymorphism, but will need to wait until the following chapter to use it in our game.

Next up, we will add some major functionality to the game. By the end of the following chapter, Thomas and Bob will be walking, jumping, and falling. ...
