Upgrading the AI Enemies

In this chapter, we will add more functionality to our AI enemies in order to introduce the potential for the player to fail, and to create greater gameplay diversity. At this point, we are going to begin settling on the kind of challenge we want to offer the player. We are going to create zombie-like enemies that will relentlessly pursue the player, creating an action-focused experience, where the player must try to survive against hordes of enemies. We will start by giving more capability to the AI, including the ability to deal damage and use wandering patterns, in order to increase the difficulty of player survival. We will then turn our attention to the player, giving them the ability to fight back against these dangerous enemies. Finally, we will complete the balancing of our increased difficulty by creating a system to spawn new enemies in the game...
