Understanding NPC Behavior in Unreal Editor

Non-player character (NPC) behaviors play a critical role in many games. From companions to bosses, merchants to guards, how NPCs interact with the world around them drives engaging, immersive gameplay. At first glance, these behaviors may seem intimidating, but in reality, most NPCs follow a strict set of logical rules. Understanding these rules is key when creating NPCs, and on this page, you’ll learn about how NPCs interact with the world, and how you can visualize and manipulate their behaviors to create your own unique experiences.

The NPC Spawner Device facilitates a lot of NPC and AI interactions. To learn more about the device see, NPC Spawner Device, NPC Character Definition, Create Custom NPC Behavior page, and Using the NPC Spawner with Animations.
