In the open world of Watch Dogs: Legion, a key component of world tone is having believable AI performing realistic behaviours. While much can be accomplished using individuals, having multi-character interactions provides a richer experience. This talk will present in detail the aLiVE Group Behaviour System, a highly modular AI architecture developed at Ubisoft Toronto. This system allows for the creation of highly reactive group behaviours, used in Watch Dogs: Legion to author ID checks, extortions, crime events, hostage scenarios, protest groups, and police interactions. When the player interacts with these scenes, the group behaviour system can properly consider the group context and roles of participants to react in realistic and interesting ways.
This talk describes in detail the AI group behaviour system used in Watch Dogs: Legion. Attendees will learn how to create a highly modular scripted AI system that manages group interactions and reactions, along with how to integrate such a system into a complex open world sandbox.
This talk is broadly aimed at AI programmers, designers, and technical animators. It will be especially relevant to individuals that work in the AAA space, and are interested in modular AI, scripted behaviours, open world AI design, or group AI interactions in particular.
