Function B2Vec2CrossVectorScalar

CommonB2Math.go:499–501

Perform the cross product on a vector and a scalar. In 2D this produces a vector.

(a B2Vec2, s float64)

/// Perform the cross product on a vector and a scalar. In 2D this produces
/// a vector.
func B2Vec2CrossVectorScalar(a B2Vec2, s float64) B2Vec2 {
	return MakeB2Vec2(s*a.Y, -s*a.X)
}
