Hello fantastic people!

In this video I show how to create a simple but effective enemy AI for a 3D game in Unity.
Even though this tutorial is horror-themed, the same techniques work perfectly for many other types of games.

We build an enemy that:
- patrols between points
- detects and follows the player
- attacks when in range
- returns to patrolling when the player is lost

The tutorial uses:
- NavMesh & NavMeshAgent
- Animator with simple state transitions
- Raycasts for line of sight
- A lightweight state-based approach

This is not an overengineered solution. It’s meant to be clear, practical, and easy to expand.
