CIVIL-AI-SYSTEM is a Unity framework designed to provide advanced AI behavior for NPCs in urban and civilian environments. The system includes pathfinding, navigation, crowd simulation, and decision-making algorithms, allowing characters to move, react, and interact realistically within cities, streets, or indoor environments. It supports dynamic obstacle avoidance, traffic integration, and customizable AI states to suit various gameplay scenarios. CIVIL-AI-SYSTEM enables developers to quickly implement lifelike civilian behaviors, improve immersion, and create responsive, interactive urban simulations across multiple platforms.
