Box2D::b2DistanceJoint - Constrains two bodies at a fixed distance.
my $joint = $world->CreateJoint( $joint_def ); my $anchor_a = $joint->GetAnchorA(); my $anchor_b = $joint->GetAnchorB();
A distance joint constrains two points on two bodies to remain at a fixed distance from each other. You can view this as a massless, rigid rod.
Get the anchor point on bodyA in world coordinates. Implements Box2D::b2Joint.
