I will build unity npc ai with stealth detection system


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.

FAQ
What Unity version does this work with?
Built and tested on Unity 6 LTS (6000.3.17f1). Compatible with recent Unity versions using the standard Physics/ Rigid body system.
Do I need to provide my own game assets (player, guard models, level)?
Yes, this gig delivers the AI logic/scripts. You'll need your own character models and scene — I'll help you wire the scripts into your existing setup.
Can the guard patrol more than 2 points?
The Basic patrol system uses 2 waypoints. Multi-point patrol paths can be added as a custom request — message me before ordering.
What's included in "source code"?
Clean, commented C# scripts (GuardVision.cs, GuardMovement.cs) with clearly labeled Inspector fields for easy configuration.
Do you offer revisions if something doesn't work in my project?
Yes — revisions are included per package (see package details). I'll debug integration issues within the revision scope to get it working in your project.
How long does Chase/Search behavior take to implement (Standard/Premium)?
Delivery times account for full implementation and testing — I'll send progress updates if your order includes these features, so you're never left wondering about status.
