  1. AI/Scripting Jon “uber” Lao Jason “PWN0R” Wong Nathan Britton

  2. AI • Balance Difficulties • Game AI creates the illusion of intelligent behavior • Anything intelligent is motivated by their environment • Assumptions about Environment • ->Game design ideas

  3. The World • Why robots killing stuffs • Buried Ancient Civilization • Metal remnants scattered throughout the land • Humans are the pot holes on the road.

  4. AI • Scutz • Scrappers • Raiders • Open Steer

  5. Scutz • Basic Enemy – size of VW Bug • Behavior: Scavengers/Workers • Goal: Clearing forests for excavating ruins

  6. Scrappers • HUGE, slow, heavily armored. • Single-track mind: destroy buildings • Gathering resources from debris • Weak point and risk

  7. Raiders • Combat oriented • Intelligent, aggressive(pursues player) • Lead and defend other robots (Scutz)

  8. Scrapper Algorithm • Serial Seeking

  9. Scutz Algorithm • Wander

  10. Scot Algorithm • Flee

  11. Raider Algorithm • Pursuit

  12. . Raider Algorithm • Lead Swarm

  13. Open Steer • Open source C++ steering library • Toolkit of steering behaviors • Sample Codes • OpenSteerDemo Framework • Windows, Linux, OSX support • Demo

  14. Scripting • Interpreted (not-compiled) for fast prototyping • Python vs Lua

  15. Python • Pros: • Open Source • Powerful • Bound w/Ogre SDK • Cons: • Very Large • Python-Ogre binding requires more software

  16. Lua • Pros: • Open Source • Small, lightweight • Cons: • Out of date documentation • Start w/nothing

  17. Python • We take care of the complexity for you! • Python up and running in 10 minutes • Ability to pull directly from Ogre
