Chapter 09 AI techniques in different game genres (Puzzle/Card/Shooting)

What is intelligence? Intelligence is part of human mental capability than involve the ability to reason, plan, solve problems, think abstractly, comprehend ideas and language, and learn. The only intelligence that human knows most is human intelligence.

What is Artificial Intelligence The science and engineering of making intelligent machines, especially intelligent computer programs The goal of artificial intelligence is a study of making machine, or program behaves like having human intelligence.

Types of Artificial Intelligence System Expert systems: A computerized system that can provide solution or reach a conclusion on subject- specific problem based on large amount of known information. Usually the system consists of an engine that can analyze information and a very large database that store huge subject-specific information for analyzing use.

Types of Artificial Intelligence System Behavior based AI The behavior modules were finite state machines and thus contained no conventional memory or learning. The behavior modules were finite state machines and thus contained no conventional memory or learning. Behavior based AI Behavior based AI The behavior modules were finite state machines and thus contained no conventional memory or learning. The behavior modules were finite state machines and thus contained no conventional memory or learning. Artificial neural networks An artificial neural network is computing solution that consists of interconnected processing units to simulate operation of the brain. It is now applied in recognition of handwritten text, stock market prediction. Fuzzy systems Fuzzy systems

Artificial Intelligence for Shooting game Typically AI is used to simulate the behavior of humans or animals. In shooting game, enemy moving is controlled by AI as well as the behavior when contact with player. These are the basics of AI in computer games.

Tracing P AI P Current position of AI controlled character Past position of AI controlled character Current position of player controlled character Path of player Path of AI Current position of player controlled character AI controlled character reach player controlled character Player controlled character was moving AI controlled character keeps checking players coordinate AI

Evading P AI P Current position of AI controlled character Past position of AI controlled character Current position of player controlled character Path of player Path of AI Player controlled character move towards AI controlled character AI controlled character avert player controlled character Current position of player controlled character AI
