Explore an in-depth overview of physics systems and workflows in Unity's Data-Oriented Technology Stack (DOTS) in this 42-minute conference talk from Unite Copenhagen. Gain insights into the design considerations behind Unity Physics and Havok Physics, understanding their distinct use cases and how they relate to classic GameObject-based physics concepts. Discover content authoring workflows for DOTS physics and learn the fundamentals of DOTS physics architecture and game code layer to optimize performance in DOTS-based projects. Delve into topics such as ECS overview, simulation pipelines, speculative contacts, deactivation, visual debugging tools, convex decomposition, and lower-fidelity rigid bodies. Join Havok's Steve Ewart as he guides you through the intricacies of physics implementation in Unity, providing valuable knowledge for game developers seeking to enhance their projects' physics capabilities.
