Artificial Intelligence (AI) in games refers to the use of algorithms and computer programs to create responsive, adaptive, and intelligent behaviors in non-player characters (NPCs). This technology enhances gameplay by making NPCs act in ways that mimic human decision-making, providing players with a more immersive experience. AI can also be used to generate dynamic game environments and challenges, adjusting difficulty levels based on player performance. Techniques such as pathfinding, decision trees, and machine learning are commonly employed to improve the realism and engagement of games, making them more enjoyable for players.
