NPC Behavior refers to the actions and responses of non-player characters in video games. These characters are programmed to interact with players and the game environment, often following specific scripts or algorithms. Their behavior can range from simple tasks, like walking or talking, to more complex interactions, such as making decisions based on player choices. Developers use various techniques to create realistic NPC Behavior, including artificial intelligence and pathfinding algorithms. This allows NPCs to react dynamically to player actions, enhancing immersion and engagement in the game world. Well-designed NPCs contribute to storytelling and gameplay, making the experience more enjoyable for players.
