A Dynamic Component Architecture for High Performance Gameplay

Delivered at GDC Canada on May 7, 2010, this presentation details a dynamic component architecture used in the Resistance franchise to represent aspects of entity and systems' behavior. This component system addresses several weaknesses of the traditional game object model for high-performance gameplay, particularly in multi-threaded or multi-processor environments. Dynamic components are allocated and deallocated on-demand from efficient memory pools, and the system provides a convenient framework for running updates in parallel and on different processors such as SPUs. The system can be layered on top of a traditional game object model, so a codebase can gradually migrate to this new architecture. The presentation discusses motivations and goals of the system as well as implementation details.
