In this presentation, Epic's Paulo Souza uses Unreal Engine's built-in AI features to build smart enemy behaviors for a game with stealth-like mechanics.

By relying on the Gameplay Framework in Unreal, we're able to quickly create convincing AI using Behavior Trees. Behavior Trees are great for creating complex AI that can be presented in a way that is easy to understand and to debug. We also make our AI react to sight and hearing senses using the AI Perception System, but also adapt our Behavior Tree decision tree as well.

In the end, we use the Environment Query System to allow our AI to be aware of the world geometry before deciding the next move, making it look way smarter than it actually is.

Body > Soul > Brain > Memory for Pawn > Controller > Behavior Tree > Blackboard.Why not use "Head" instead of "Soul" for the Controller? It'd make sense to have the combo Body + Head, and have the Head contains a brain.. But for a Soul to have a brain? Weird... :p - Unreal Engine AI with Behavior Trees | Unreal Engine

Thank you for including our work at the  minute. I'm very happy to be part but I have to mention my collaborator https://www.youtube.com/@Haylox (Hayley Rumbold) because without her the cinematic would not exist. She was the Cinematic Artist in the project. I'm flattered the work is in, truly, thank you again, but I feel bad for her name being ommited. I had mentioned her as an integral part of the project, in your call for submissions page. Instead of my name being listed twice, with a repetition of it with a tiny Artstation logo next to it, I think a much more proper format would have been to have Hayleys name in as well. - Unreal Creators Showcase | GDC 2024
