AI Player System

Smart automation and human-like behavior for events, farming and PvP.

AI Player System

Overview

A complete AI player system for a High Five server that needed its world to feel populated around the clock without inflating real online numbers dishonestly.

The challenge

New servers feel empty at off-peak hours, which hurts retention. Off-the-shelf bots move in straight lines, stack on one spot and are trivially obvious - they make a server look worse, not better.

Our solution

We built AI players driven by behavior trees and per-profile configuration: class-appropriate skill use, party formation, geodata-aware pathfinding, believable farming routes and event participation. Population scales by zone and time of day, and thins out automatically as real players arrive.

Key features

  • Human-like behavior and rotation
  • Auto farming and resource management
  • Smart target selection and pathfinding
  • Event participation and PvP support
  • Customizable AI profiles
  • Safe, rule-respecting design
