Baby AI
• What does it look like NOW?
Game Tuning Workshop
Technical Considerations
• Designers can’t do it all by hand!
• Each AI should have a “style” or “personality” Easier to recognize/predict Different targets require different skills
• This means more granularity – more complex representation.
Game Tuning Workshop
Technical Considerations
• Hiding How much cover is the fern...as opposed to
the closet or under the table? Do AIs perceive others and plan around
them? Do they track the babysitter? What if they can turn on and off lights?
Game Tuning Workshop
Technical Considerations
• What about sound? Doors make sound, so do hardwood floors. How sensitive to sound is the babysitter, are
the kids?

Conclusions?
• How would you do it?
• Making tag different?
