Lesson 06.1 – Creating the remaining classes

Lesson Objectives

At the end of this lesson, you will know…

• Nothing new. However, you do need to create the rest of the classes, so you can eventually play the game.

Time to add more classes

Now we can create the rest of the classes you’ll use in the game.

By the way, some programmers would call these classes the “business classes”, or “business objects”. Even though this is a game, and not a business application, that’s a term you might hear.

Step 1: Start Visual Studio Express 2013 for Desktop, and open the solution.

Step 2: Right-click on the “Engine” project, in Solution Explorer, then select “Add”, and then “Class”.

Enter the name of the new class to create, and add the properties in the class – just like you did with the Player class.

Copy the code below, to ensure the spelling and casing if the classes and properties is correct. That will be important when we start using the classes – because C# is case-sensitive.

It may not be obvious what all the properties will be used for, but I’ll discuss them when we use them in the future lessons.

Summary

There wasn’t really anything new in this lesson. We just need to add these classes to make the game actually do something.
