Herd | Herd Simulation/ Animal NPC/ Fauna Simulation Framework

The Deer Behavior asset brings lifelike AI to Unity projects, simulating natural deer movements and reactions, perfect for adding immersive wildlife to open-world adventures, nature simulations, or bustling ecosystems. Deer transition seamlessly between grazing, wandering, idling, and fleeing states, creating realistic movement and decision-making. When danger is detected, they dynamically calculate a flee direction and avoid obstacles using raycasting for smooth, believable escapes, then naturally return to idle or wandering states, maintaining a lifelike presence. Integrated obstacle detection ensures navigation around objects while moving. Behaviors are fine-tunable with adjustable settings for movement speed, fleeing distance, grazing time, and detection radius. Easy-to-use inspector fields and gizmos let you define grazing areas, set danger layers, and visualize deer behaviors.
