About this gig

Need a smart, working NPC guard AI for your Unity stealth or horror game?


I will build a custom Guard AI system tailored for your project. This system features: 


  • Dynamic Patrol System Guard moves seamlessly between custom-defined waypoints
  • Field-of-View Vision Cone realistic raycasting-based detection (not just simple distance checks)
  • Obstacle-Aware Line of Sight guards can't see through walls or props
  • Dynamic Rotation guard faces its movement direction, vision cone updates in real time
  • Alert State System clean state transitions when the player is spotted
  • Visual Debug Gizmos see exactly how detection works during development


This is built using Unity's native Physics.Raycast system for accurate, performant detection not a shortcut asset-store plugin.


What you will receive:

  • Clean, well-commented C# scripts
  • Easy-to-configure Inspector fields (view distance, view angle, and obstacle layers)
  • Integration support for your existing project 


Perfect for: Stealth games, horror games, prison-break prototypes, or any project needing smart NPC awareness. 


Let's discuss your specific game mechanics message me before ordering if you have custom requirements.

I'm a self-taught Unity developer building AI systems and game mechanics from the ground up. Currently focused on NPC behavior, detection systems, and stealth AI — I enjoy solving the logic behind how game characters "think" and react. Always happy to discuss your project's specific needs before you order.
