You're working on a game that involves enemy wizards dueling each other. Each wizard has at least a dozen different spells at his disposal -- some of them simply inflict damage, while others will temporarily stun or immobilize an enemy, slow him, prevent him from casting spells for a brief duration, teleport the caster a short distance, or give the caster a temporary shield. A wizard can only cast one spell at a time, but each spell has a fixed cooldown (time before it can be cast again) and an associated mana cost (assume no mana regeneration). Describe some ways you might implement a competent AI system for a wizard.

Using the example of the Thief-like AI system in the previous section, how do you implement the 'search for player' behavior for the guards, and get them to search an area in a believable fashion? How do you make sure this searching behavior isn't too challenging for players, and ensure that it's usually possible for the player to escape the search if he plays the game well?

In one room in your game, there's an elevator that AIs will need to use to escape from the player. In order to use the elevator, they have to walk over to a special button on the wall, press it to summon the elevator, then walk into the elevator and press another button to tell it to ascend. How would you design a system to make sure AIs can do all of these things in the proper order? If you have 3 AIs in the room, how would you design the system to make sure they can all escape in the elevator at the same time? What happens if one of them dies while they're trying to do this, and how do you make sure the other AIs don't get stuck waiting for that dead AI?

You're developing a boss encounter in a 3D platformer game, and the boss has 15 different attacks. The game designers have asked you to make sure that the player sees as many of those 15 attacks as possible during the encounter, and that he seldom or never sees the same attack twice in a row. What are some ways you can do this? What does the attack selection algorithm look like in this case? Keep in mind that not all attacks are possible all the time -- for example, the boss has a melee attack that he can only do when the player is very close, and a bombardment attack he can only do when the player is far away.

You're tasked with implementing a computer player for a real-time strategy (RTS) game. Assuming that there is no fog-of-war, how do you implement a system to allow the computer player to determine what parts of the map are controlled by enemy players, and which parts are open to easy exploitation? How do you identify the choke points on the map? How do you find the boundary between the parts of the map under your control and the parts of the map controlled by enemy players? How do you detect an impending enemy attack or a change in an enemy's offensive posture?
