Hide & Seek AI in Unreal Engine 5 – Part 3 | AI Perception System Upgrade

Welcome to *Part 3* of the Hide & Seek AI series in Unreal Engine 5! In Episode 2, we built a system where the NPC searches for the player by checking different hiding locations using a basic line trace setup. Now in this episode, we take things further by upgrading the AI to use **Unreal’s AI Perception system**. This allows the NPC to **properly see and detect the player**, making the behaviour far more realistic, scalable, and production-ready. 🧠 *What We Cover:* ✅ Replacing line trace detection with AI Perception ✅ Setting up sight senses in Unreal Engine ✅ Detecting the player using perception events ✅ Improving AI awareness and responsiveness ✅ Integrating perception into the existing search system ✅ Making the AI behaviour more believable This upgrade is a big step towards creating *smart, reactive AI systems* that can be used in: • Stealth games • Horror games • Guard AI systems • Investigation mechanics • Dynamic NPC behaviours If you're building AI in Unreal Engine, this is a key system you’ll want to understand. 🤗 Connect With Me: 👉 https://www.d3kryptionstudios.com/ 🔷 Join the Community: 👉 Discord:   / discord   👉 Twitter: https://x.com/D3kryption 👉 Instagram:   / d3kryption   👉 Patreon:   / d3kryption   🙌 Enjoyed the episode? 👍 Like the video 💬 Comment what AI feature we should add next 🔔 Subscribe for more UE5 AI tutorials & systems #UnrealEngine5 #UE5Tutorial #UnrealAI #AIPerception #GameDev #StealthAI #IndieDev #UnrealEngineTutorial #D3kryption
