In this chapter, we're going to peel away the veil of this mysterious realm to examine these smallest but most important components of the video game universe. With the help of a bit of easy math, vectors are the key to decoding the entire geometry of the space of your game environment. Learning how to work with them gives you unlimited control over your games.
How would you feel if you could control gravity, wind, the trajectory of bullets, and the laws of physics and thermodynamics at will? Like a character from the Matrix, you will have that kind power in your own game world.
