C++ Fast-track for Games Programming Part 17: AI

Like physics, AI (Artificial Intelligence) is an incredibly complex field, and it’s always changing. Some companies allocate entire teams to the subject to make their game provide challenging game play. So we will only cover a few very basic concepts in this tutorial.

C++ Fast-track for Games Programming Part 15: File I/O

Before we continue with typical game related topics, you need to know a few more general techniques that will help you when you write your games. One of these techniques is file I/O. File I/O stands for Input/Output. You are of course already performing file I/O operations, for example when you load an image. However, this is handled by some image library (FreeImage). Sometimes, you simply want to store your own data.

In part Part 9 you worked with colours and were introduced to the noble art of bitmagic. Here’s a quick refresher: multiplying an integer value by a power of 2 can be done by shifting its (binary) bits to the left.
Division is similar, except this time you shift to the right. So for example, $$6a$$ is equivalent to $$2^2a+2a$$ which is equivalent to (a<<2)+(a<<1) using bit-shifting operations. Being aware of the number of bits in a variable is especially important if more than one number is stored in the bits of a 32-bit integer. This is is the case for 32-bit colours: Each of the red, green, and blue components each use 8-bits with the alpha component completing the 32-bits to represent a single pixel.

C++ Fast Track for Games Programming Part 13: Data Structures

You are quite far into the C++ Fast Track preparation for Games Programming tutorial series. If you got here in good shape, you learned a lot: you went though the basics of C++ programming, and got a taste of object oriented programming as well. In the meantime, you experimented with quite a few game related concepts. In the upcoming parts, you’ll further expand your knowledge, with more info on bit magic, file I/O, graphics programming and game development in general. But first: let’s get acquainted with the wonderful world of data structures.

C++ Fast-track for Games Programming Part 9: Colours

In this article we will return to the numbers that represent colours, as demonstrated in the second instalment of this series. This can only be done through the wonderful world of bit magic, which is by the way a very nice place to be, so we will explore it thoroughly.

# C++ Fast Track for Games Programming Part 8: Memory Addresses

C++ Fast-track for Games Programming Part 8: Addresses

One of the harder concepts in C++ is the concept of pointers. Pointers have everything to do with the very nature of the language: C++ gets you pretty close to the hardware you are working with, and one of the most important parts of that hardware is memory. In this tutorial, you will learn to use pointers to refer to memory addresses.
