Unreal Engine Enemy AI With Behavior Trees and Combat
In this tutorial, you will build a distance aware enemy AI in Unreal Engine that follows the player, pauses intelligently, and attacks only when close enough to hit. The system is built using Behavior Trees, Blackboards, and clean Blueprint logic that stays readable and easy to expand.
You’ll learn:
How to set up an enemy AI using Behavior Trees and Blackboards
How to detect the player using distance based collision logic
How to trigger attacks with custom Behavior Tree tasks
How to apply damage and connect AI combat to a player health system
By the end, you will have a fully working enemy AI that follows the player, waits at range, attacks with animations, deals damage, and integrates cleanly into a complete gameplay loop.
