Beginning C++ Game Programming

Chapter 2. Variables, Operators, and Decisions – Animating Sprites

In this chapter we will do quite a bit more drawing on the screen and to achieve this we will need to learn some of the basics of C++.

Here is what is in store:

• Learning all about C++ variables
• Seeing how to manipulate the values stored in variables
• Adding a static tree, ready for the player to chop
• Drawing and animating a bee and three clouds

C++ variables

Variables are the way that our C++ games store and manipulate values. If we want to know how much health the player has then we need a variable.
