Video: Deterministic vs. replicated AI: Building For Honor's battlefield

In this 2017 GDC talk For Honor devs Frederic Doll and Xavier Guilbeault explain how Ubisoft created a big, active battlefield on the backbone of a distributed peer-to-peer deterministic simulation.

In this 2017 GDC session, Ubisoft's Frederic Doll and Xavier Guilbeault explain how the team at Ubisoft created a believable large scale battlefield on the backbone of a distributed peer-to-peer deterministic simulation in For Honor.

The pair offered up an in-depth look at how this was achieved, from the importance of metadata built in the world, to levers given to designers to control many actors, including building complex and interesting behaviors by using simple but elegant rules.

They also showed how, with requirements ranging from high-level objectives to reactive decision-making, including environmental awareness, creating deep and challenging AIs required its own pipeline: a replicated decision system, using extracted data from Ubisoft's fight logic, tools to empower the AI designers, and automated testing to validate design intentions.

It was an intriguing talk, especially if you're looking to learn more about how AI can help you build better games, and now you can watch it for free over on the official GDC YouTube channel!
