After completing this chapter, you will be able to

• Understand that a vector relates two positions to each other

• Recognize that all points in space are position vectors

• Comprehend that a vector encapsulates both a distance and a direction

• Perform basic vector algebra to scale, normalize, add, and subtract vectors

• Apply vectors to control the motions of game objects

• Implement simple game object behaviors like aiming and following

• Design and simulate simple external ...
