Kart Physics & Multiplayer Replication
Problem: A kart racer needed responsive, fair-feeling physics across up to 8 networked players without desync or rubber-banding, while giving designers a fast iteration loop.
Approach: Built a specialised physics module and API on top of the engine, implemented client-side prediction with server reconciliation and interpolation for replication, and shipped internal debugging/trace tools so designers could inspect real gameplay data directly.
Result: 20% reduction in kart-physics development time, 40% reduction in level-design iteration time, and stable 8-player replication shipped in DreamWorks All-Star Kart Racing.
