FAQ

Here are some questions that might be on your mind:

Q) I am struggling with the content presented so far. Am I cut out for programming?

A) Setting up a development environment and getting your head round OOP as a concept is probably the toughest thing you will do in this book. As long as your game is functioning (drawing the background), you are ready to proceed with the next chapter.

Q) All this talk of OOP, classes, and objects is too much and kind of spoiling the whole learning experience.

A) Don't worry. We will keep returning to OOP, classes, and objects constantly. In Chapter 6: Object-Oriented Programming, Classes, and SFML Views, we will really begin to get grip with the whole OOP thing. All you need to understand for now is that SFML has written a whole load of useful classes and we get to use this code by creating usable objects from those classes.

Q) I really don't get this function stuff.

A) It doesn't matter, we will return to it again and will learn about functions more thoroughly. You just need to know that, when a function is called, its code is executed, and when it is done (reaches a return statement), then the program jumps back to the code that called it.
