Simple NPC Follow AI (Unity)

A simple and easy-to-use NPC Follow AI system for Unity.

This package lets you drop an NPC into your scene and have them automatically follow the player using Unity’s built-in NavMesh system. NPCs can walk around obstacles, move down ramps, climb up platforms, and stop at a customizable distance when they reach the player.

Perfect for companions, pets, friendly NPCs, and prototypes.

Everything is organized and ready to go — just import the package, open the demo scene, and hit Play.
