#Rigid Body Dynamics

Rigid body dynamics are provided by Jolt Physics through the Rigidbody component.

#What's Implemented

• Motion types — Static (immovable), Kinematic (scripted), Dynamic (physics-driven)
• Gravity — Configurable per-body gravity factor (default world gravity: 0, -9.81, 0)
• Friction — Surface friction coefficient per body
• Restitution — Bounciness per body (0 = no bounce, 1 = perfectly elastic)
• Linear damping — Velocity decay over time
• Angular damping — Angular velocity decay over time
• Fixed timestep — 1/60s accumulator pattern for stable simulation
• Auto body creation — PhysicsSystem automatically creates Jolt bodies for entities with Rigidbody + Collider + Transform
• Transform sync — Position and rotation are read back from Jolt each frame for dynamic bodies

See the Physics feature page for usage examples.
