The Next Vector: Improvements in AI Steering Behaviors (GDC Link)

Format: 60-minute Lecture

Speakers: Andrew Fray, Graham Pentheny

While not receiving as much attention as their pathfinding kin, there is little denying that steering behaviors have their place in modern games. However, as with any technology, traditional steering behaviors have their edge cases and quirks. This lecture will present examples of how steering behaviors have advanced recently and how they can be used to provide more realistic movement in demanding situations. In one example, we will show how steering enabled the rapid coordinated movement of hundreds of agents in the mobile game, Fieldrunners 2. In another, we will present the method used in a AAA racing game which fixed some of the common problem that occur with traditional steering algorithms.

The session shows multiple techniques to apply steering behaviors as standalone solutions or to augment existing pathfinding.
