Presentation Transcript

  1. ‘Look at Those Two AIs Over There’ Dr Dave Ellison Division of Complex Systems School of Computing and Creative Technologies University of Abertay Dundee

  2. Outline • The Goodies • The AI for Games Module • A look at the module, its content, delivery and problems • Covers many areas, many of which could be a module in themselves – think GAs or ANNs 'Look at those two AIs over there'

  3. The Goodies Part 1 • Action oriented AI – Chasing, Pattern Movement • Finite State Machines, Rule-Based Systems, Scripting • Pathfinding • Genetic Algorithms • ANN Chasing and Evading with Brains • Learning to walkFully TrainedExplode 'Look at those two AIs over there'

  4. The Goodies Part 2 • Emergent Behaviour (Flocking, Schooling etc) • Decision Making (fuzzy logic, probability theory etc) • Agent-Oriented Programming/ALife (Seeing, hearing, planning agents)Goldfish 'Look at those two AIs over there'

  5. The AI for Games Module • New Course – 2nd time presentation • Covers many areas, many of which could be a module in themselves – think GAs or ANNs • 12 Lectures, 2 Lecturers • Assessment: • Essay • 3000 line AI Project • WebSite 'Look at those two AIs over there'

  6. ‘Look at Those Two AIs Over There’ • An “AI” Caution: • Game programmers use “AI” very differently from the way used by academic researchers in AI • AI designates a noun rather than an acronym. • An AI is any entity in a game which exhibits intelligent behaviour. For example, “look at those two AIs over there.” • Academics find this bizarre. • AI always an acronym denoting a large subfield of Computer Science • AI is never used in the plural • AI never denotes entities which exhibit intelligence. • Becoming feasible to include “harder” physics • Overlaps with other disciplines, such as graphics, maths, numerical methods etc • Physics engines handle rigid bodies, differential equation solvers, in real time 'Look at those two AIs over there'

  7. Problems • Books: • No one book covering the area: • Bourg, David M. & Glenn Seemann. AI for Game Developers, O’Reilly, 2004 • Byl, Pennie Baillie-De. Programming Believable Characters for Computer Games, CharlesRiver Media, 2004 • Sánchez-Crespo Dalmau, Daniel. Core Techniques and Algorithms in Game Programming, New Riders, 2004 • Some available as e-books through the University Library as Safari Texts • Quality of Material: • Exercise your critical faculties as you read. You will find that game AI literature ranges from the sublime to the ridiculous. 'Look at those two AIs over there'

  8. Problems (2) • Presentations: • Difficulties in running demos and programs 'Look at those two AIs over there'

  9. Conclusions • Over view of module • Many topics could constitute a module • Presentation of programs – difficult to see effect of AI • No ideal book • Material available varies in quality 'Look at those two AIs over there'
