Simulation

From the early days, simulated physics has been the foundation of the way users build in Roblox.

The Simulation Core team develops Roblox's proprietary physics engine. Our team shapes the architecture of the simulation engine, handling collision detection, how we step the world, optimizing for low-level performance, and dictating how both the game engine and external developers work with physics.
