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)

Location: Room 2002, West Hall

Date: Tuesday, March 21

Time: 2:10 pm - 2:40 pm

Pass Type: All Access Pass, Summits Pass

Topic: Programming

Format: Lecture

Vault Recording: Video

Audience Level: All

This session explores the unique AI challenges faced during the development of Inflexion Studio's debut title, Nightingale, a co-op survival-crafting experience in which players venture through portals where adventure and mystery await across a myriad of beautiful and increasingly-dangerous procedurally generated realms.

Arta Seify and Nathan Sturtevant will describe the range of approaches crafted during development to solve challenges in pathfinding and populating the realms with creatures. Learn about the systems devised to support efficient pathfinding across large realms with a changing path network, creature terrain-type preferences, pathfinding for creatures of vastly different sizes, and procedurally filling the realms with wildlife such that they “feel alive”.


Attendees will learn how abstraction techniques can be combined with navigation meshes to support pathfinding and gameplay opportunities in larger worlds. They will also see methods for filling procedural worlds with creatures.

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.
