Interface: RigidBody ​

Defined in: rigidbody.ts:17

Rigid body interface for 2D physics simulation.

Remarks ​

Represents a physical object in the physics world with mass, velocity, rotation, and collision properties. Can be either static (immovable) or dynamic (responds to forces).

Implemented by Circle and Polygon classes.
