This structure is used to report contact points.
Properties
public friction: number
The combined friction coefficient.
The contact id identifies the features in contact.
public normal: b2Vec2
Points from shape1 to shape2.
public position: b2Vec2
Position in world coordinates.
public restitution: number
The combined restitution coefficient.
public separation: number
The separation is negative when shapes are touching.
public shape1: b2Shape
The first shape.
public shape2: b2Shape
The second shape.
public velocity: b2Vec2
Velocity of point on body2 relative to point on body1 (pre-solver).
