The AI in Killzone 2’s Bots: Architecture and HTN Planning

Recording / The AI in Killzone 2’s Bots: Architecture and HTN Planning

Description

KILLZONE 2 was one of the most anticipated titles of early 2009. While the quality of the graphics is immediately obvious, the game also received acclaim for its dynamic and adaptive AI. This is most obvious in multiplayer mode, featuring both online and offline bots that battle in a mission-based game environment.

In this presentation from the Paris Game AI Conference 2009, you'll learn about the architecture behind the AI for the Killzone series that has evolved over the years. You'll also discover exclusive details about the hierarchical task network (HTN) planner that was entirely written for the next-gen experience in KILLZONE 2.
