Box2D::b2PulleyJoint - Connects two bodies and two ground points.
my $joint = $world->CreateJoint( $joint_def );
my $ratio = $joint->GetRatio();
The pulley joint is connected to two bodies and two fixed ground points. The pulley supports a ratio such that: length1 + ratio * length2 <= constant
Yes, the force transmitted is scaled by the ratio. The pulley also enforces a maximum length limit on both sides. This is useful to prevent one side of the pulley hitting the top.
