TRANSCRIPT
Adding AI to your game End of development,
time to put in AI! How to connect
everything?
Game Theory A game is a series of
decisions Info goes in: board
state, options Decision comes out:
pick a possible move Make use of statistics
Game of the Goose Throw a dice, move
that many steps. First to the end wins Not a game!
Rock, Paper, Scissors Pick any of 3
gestures Each gesture beats
one other
Turing Test Impossible to
distinguish human from computer
AI can pretend to be a human opponent
AI can replace a lost player
Artificial Intelligence Search Problems BEST: Find the best
solution from a range FAST: Find a good
enough solution fast Making good decision
= finding a good solution
Racing Game Individual opponents Multiplayer / Single Traffic is also AI Rubber Band
Intelligent Agents Autonomous entities Observe through
sensors Acts upon
environment using actuators
Intelligent Agents Autonomous entities Observe through
sensors Acts upon
environment using actuators
Emotions Change parameters
based on events Aggressive,
Defensive, Panic, Revenge...
Class Strategies
Platformer Player vs World Run, jump and shoot
Trial and Error Limited number of
options Calculate best from
many tries Pick best or retry
(TAS) AI can try without
actually acting
Real Time Strategy / Sports
Player (human/AI) controls a team
Each unit is also an agent
Self-Organizing Systems Ants leave
pheromones, path to food
Equivalent to a shortcut
Shooter Individual agents Big difference
monsters and soldiers
Machine Learning Machine Learning to
study patterns Might classify player
strategy
Neural Networks Predict player
behavior Guard favorite spots Ambush player
Fighting Game Player vs Player Remember combo's Timing of buttons
Imperfection and Randomness
AI can input combo's perfectly
AI knows everything about the world
Add mistakes on purpose
Add randomness in any function
Dungeon Master AI controls entire
game world Weather, characters,
animals.. Even flow of the
game
Conclusion No single AI solution Define entities
independent of human/AI
Find the right strategy (or mix) for your game
