AI Summit: Living in Procedural Worlds: Creature Movement and Spawning in 'Nightingale'

Arta Seify  (AI Programmer, Inflexion Games Inc.)

Nathan Sturtevant  (Professor, University of Alberta, Inflexion Games Inc)

Pass Type: All Access Pass, Summits Pass

Topic: Programming

Format: Lecture

Vault Recording: TBD

Audience Level: All

This session explores the unique AI challenges faced during the development of Inflexion Studio's debut title, Nightingale, a shared world survival-crafting game set in a rich Gaslamp Victorian fantasy setting. Players venture through portals where adventure and mystery await across a myriad of beautiful and increasingly-dangerous worlds.

Arta Seify and Nathan Sturtevant will describe the range of approaches crafted during development to solve challenges in pathfinding, populating the realms, and combat. Learn about the systems devised to support efficient pathfinding across large realms with a constantly changing path network, creature terrain-type preferences while traversing the realms, and support for creatures of vastly different sizes.


Attendees will learn how abstraction techniques can be combined with navigation meshes to support pathfinding and other gameplay mechanics in larger worlds. They will also see methods for filling a procedural world with creatures. Lastly, they will be introduced to how a utility action system can create collaborative actions.

Intended Audience

This is for AI designers and programmers: This is a technical session with algorithmic/implementation details. Session covers both the technical systems that were built and the design motivations behind them.
