Unreal Engine 5 Enemy AI #3 – Chasing the Player & Forgetting System
Want to build a smarter enemy in Unreal Engine 5—one that can chase the player and then realistically forget about you and return to patrol? This video is for you!
In this part of my Enemy AI Blueprint series, we move beyond simple patrols. You’ll learn how to make your AI spot the player, chase them with increased speed, and then forget the chase after a set time, using AI Perception (Sight), the Max Age setting, and some crucial but easy-to-miss project tweaks. I’ll guide you step by step, and share insider troubleshooting tips that’ll save you hours if your Blueprints start acting up or get “stuck.”
What you’ll learn in this episode:
Fine-tuning AI sight, lose-sight radius, and vision angle for real gameplay
Understanding Max Age and Unreal’s “Forget Stale Actors” system
Making the enemy chase the player only when detected, using “AI Move To”
Programming the enemy to slow down and resume patrol when they lose the player
How to debug and fix “sticky” Blueprint or cache problems that can break your AI logic
How to visualize AI vision cones in Unreal Engine 5.6
