Audience Level: I acknowledge GDC 2021 is an all-digital event and commit to participating virtually.

In this rapid-fire post-mortem of the AI for "Wolcen: Lords of Mayhem" and its most recent chronicle "Bloodtrail" we discuss what went right, what went wrong, and what lessons were learned. We discuss Bloodtrail generation, a novel approach to pathfinding that selects a route based on aesthetics and player experience, rather than length. We present Contextual Steering, a new approach to collision and obstacle avoidance without the pitfalls of ORCA or more traditional, boids-style steering forces. Finally, we describe the trials and tribulations we went through as we implemented the flexible formation system that supports the Roman-style rank and file of the Republic formations.

Takeaway

Attendees will walk away with new techniques in navigation and steering that can be applied not just to action-RPGs, but more broadly to AI for games in many genres, as well as lessons learned while implementing formations.

Intended Audience

This presentation is primarily intended for intermediate to advanced AI developers.
