Class: VisualPolygonBody
Defined in: rigidbody.ts:546
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.
