RE2 Mr. X - Behaviour Tree

A technical exploration and recreation of the 'Mr. X' AI system from Resident Evil 2 Remake (2019) using my own implementation of a Behaviour Tree (BT) system. This project serves as my first dive into video game AI by creating a BT from the ground up.

Mr. X is a video game AI that hunts the player through the level, stalking the halls and searching rooms. I've attempted to reproduce that behaviour to learn how to create a basic BT system.

Check out the devlog!

Features

  • Custom Behaviour Tree built from the ground up with behaviour mimicking RE2’s Mr. X within Unity.
  • Various Node types such as CompositeActionDecorator and more to create patrol, search, chase and attack behaviours.
  • Room System with AI Door handling for Room-to-Room navigation.
  • Door Handling solution enabling the AI to interact with and navigate through Doors effectively.
  • Object-Oriented architecture using inheritance to define type-based and abstract logic.
  • Room real-time lighting optimisation techniques.
  • Fully playable vertical slice with traditional gameplay systems to test AI implementation in an in-game setting.

Assets

Note: Capcom reserves all rights to the 'Mr. X' character. I do not claim to own this character, only use his likeness in an AI development study out of my love for the franchise.
