<p>Next-Gen Content Creation for Next-Gen AI Damin Isla, Naimad Games Slide 2 AI Content Creation Whats the best way to author AI content for games? (And who does the authoring?) (And what is AI Content in the first place?) Slide 3 Photoshop of AI Panel, GDC 09 Slide 4 Slide 5 Slide 6 Slide 7 The Starting Point The central competency of Game AI is expressive power for the behavior author, not intelligence Intelligence is only useful insofar as It enables gameplay It supports the fiction It makes the game more fun Slide 8 The Problem AI is HARD Technically complex Highly interconnected Impossible to test Culturally awkward Slide 9 The Problem Designer Engineer Fundamentally not in a position to fully specify all fun- relevant behavior Fundamentally not responsible for fun Slide 10 2 Solutions 1. Need a new breed of engineering-competent designers or design-sensitive engineers (Michael Mateas) 2. Need better authoring paradigms, a Photoshop of AI (Chris Hecker) Slide 11 The Photoshop of AI Why has game AI not settled on Common control structures Common authoring paradigms Common metrics Common APIs Why are we so very, very far from WYSIWIG?

Slide 13 AI Content Creation How do we currently author AI content for games? Slide 14 AI Content Creation AI is HARD Technically complex Highly interconnected Impossible to test Culturally awkward The path of least resistance: do it in code The path of least resistance: do it in code Slide 15 AI Content Creation EngineerDesigner Everything in code- All procedure in codeExposed parameters Framework in code Visual construction / managed coding HarnessEverything in script Slide 16 Slide 17 Disclaimer(s) This is my own highly-biased point of view.

Questions: Iteration time Tweakability Transparency Are we learning the right things? Are we learning the deep structure? Slide 42 N-Grams They say all lovers swear more performance than they are wont to keep obliged faith unforfeited. - Shakespearean Quadrigram Troilus and Cressida Merchant of Venice Deep Structure Fail Slide 43 The State of the Art The Periphery Slide 44 Kynapse UnrealEd Plugin, Autodesk Slide 45 Havok Behavior Slide 46 Endorphin, NaturalMotion Slide 47 Slide 48 The Future Middleware continues to eat away at the periphery of the intelligence problem Intelligent animation Pathfinding Gesture recognition Vision Natural language Behavior Capture But what about the Photoshop of AI? Slide 49 The Photoshop of AI Warning: Craziness ahead Slide 50 Slide 51 ??
