Audience Level: Intermediate

Learn how Just Cause 4' copes with a wide range of vehicles and player styles though thoughtful design of its tire dynamics and how these relate to the overall vehicle gameplay experience. This talk is intended to take physics programmers and technical vehicle designers through the decision making and thought process so that they have a deeper understanding of the trade-offs they can make in their own games to achieve a balance of believability and fun. The talk will take attendees through the magic formula tire model, why it may not be optimal for arcade and 'simcade' handling, and proposes a more designer friendly approach which is not semi-empirical, has considerably fewer parameters and produces more player friendly results.


Attendees will gain insight into making the right technical decisions on shaping their vehicle dynamics and in particular on their tire models when building a vehicle physics model. The focus will be on "arcade" to "simcade" handling models, where the interplay of believability and fun is crucial.

Intended Audience

This talk is for technical designers and physics programmers looking to improve the driving experiences in their games. Understanding of game math and physics is recommended.
