The Brain in the Game
1 like81 views
The document discusses the use of artificial intelligence (AI) in video games, detailing its applications like non-player character (NPC) behavior and procedural content generation. It highlights the pros and cons of game AI, provides historical examples such as Pac-Man's ghosts, and examines different methods of content generation. Additionally, the discussion covers the complexities of AI in creating engaging gameplay while managing unpredictability and level design challenges.
The Brain in the Game
- 1. The Brain in the Game Use cases of AI in video games
- 2. I'm sorry Dave, I'm afraid I can't do that... https://www.youtube.com/watch?v=ARJ8cAGm6JE
- 3. Gil Steiner Full stack engineer Game developer & designer gilsteiner.com gamesgil@github
- 4. Non Agenda Player AIs / Bots Complicated algorithms
- 5. Agenda What is AI in game context? Artificial life Some history Procedural content generation Autonomous Behavior Simulation Action
- 6. What is Game AI? A set of algorithms which rule an NPC behavior A set of algorithms which auto-generates content
- 7. Game AI - Pros Natural feel Cover for the lack of real human opponent Make up for human effort
- 8. Cons Humans are less predictable An NPC can easily become too easy or too hard to beat Lose control over level design
- 9. Artificial Life - Cellular Automata Conway’s Game of Life (demo) http://gilsteiner.com/content/demos/life/
- 10. Artificial Life - Langton’s Ant Complex and unpredictable behavior from a very simple ruleset (demo) http://gilsteiner.com/content/demos/langtonsant/
- 11. Pac Man’s Ghosts - Chase Mode Blinky - follow aggressively Pinky - ambush Inky - unpredictable general patrol Clyde - wander randomly who tends to stay out of the way
- 12. Historical Context - Pac Man’s Ghosts Scatter Mode Blinky - top right corner Pinky - top left Inky - bottom right Clyde - bottom left
- 14. Random vs Procedural Random - the pool remains static and gets redistributed by chance Procedural - the pool is potentially infinite and can also be adaptive
- 15. Roguelikes Originally super rough ASCII art style Randomly generated dungeons, enemies & loot Progressively harder Permadeath
- 16. Minecraft (and others) Procedurally generated environment Randomly located assets, NPCs and events Terrain is based on a random seed connected to the system clock/manual
- 17. No Man’s Sky 2^64 worlds Procedurally generated Common seed allowing players to visit the same planets
- 19. Cons QA hell There is no clear definition of “makes sense” or “nice” Scale sounds nice at first but where is the purpose? Shared experience? Lack of personal touch
- 20. Simulation - The Sims FreeSO, SocioTown, Spore etc.
- 21. Action - Alien: Isolation
- 23. Adaptive Difficulty Level When the player gets going - the game gets tough https://youtu.be/LlmAv48k1pY
- 24. Code Review
