Game AI refers to the artificial intelligence systems used in video games to create responsive, adaptive, and intelligent behaviors in non-player characters (NPCs). This technology helps make games more engaging by allowing NPCs to react to player actions, navigate environments, and make decisions that enhance gameplay. Developers use various techniques to implement Game AI, including pathfinding algorithms, decision trees, and machine learning. These methods enable NPCs to simulate realistic behaviors, such as seeking cover in a shooter game or collaborating with other characters in a strategy game, ultimately enriching the player's experience.
