Trouble Implementing Custom AI Behavior in Unreal Engine

Greetings Unreal Engine Community,

I’m currently working on a project where I’m trying to implement custom AI behavior for non-player characters (NPCs) in my game. However, I’m encountering some difficulties in achieving the desired behavior, and I’m seeking guidance from fellow developers.

Here’s a brief overview of my project setup:

  • I’m developing a third-person action-adventure game using Unreal Engine.
  • I have created several NPC characters that need to exhibit complex behaviors, such as patrolling, interacting with objects, and engaging in combat.
  • While Unreal Engine provides built-in AI functionalities, I need to implement custom behavior trees and AI logic to achieve the specific behaviors required for my NPCs.

The problem arises when I attempt to implement custom AI behavior for my NPCs. Specifically, I’m facing the following challenges:

  1. Behavior Tree Design: Designing effective behavior trees that accurately represent the desired NPC behaviors without becoming overly complex or difficult to manage. How can I structure my behavior trees to ensure flexibility and scalability as my project evolves?
  2. Navigation and Pathfinding: Ensuring that NPCs navigate the game environment smoothly and efficiently, especially in complex or dynamic environments. How can I optimize pathfinding algorithms and navigation meshes to handle diverse terrain and obstacles?
  3. Interactivity and Perception: Implementing NPC interactions with objects and other characters, as well as establishing perception systems to detect and respond to environmental stimuli and player actions. What techniques or strategies can I use to create responsive and immersive NPC behaviors?
  4. Performance Optimization: Balancing the complexity of AI behaviors with performance considerations to maintain a smooth and responsive gameplay experience. How can I optimize AI processing and resource usage to minimize performance impact, especially in large-scale environments with multiple NPCs?

I’ve explored Unreal Engine’s documentation and tutorials, but I’m still struggling to overcome these challenges in implementing custom AI behavior for my game. Any insights, tips, or examples from developers experienced in AI programming within Unreal Engine would be greatly appreciated.

Thank you for your help and guidance!

Is there anyone who can help me with this? I would love your guidance. :slightly_smiling_face: :upside_down_face: Thanks!
