Constructor detail
RigidBodySpring()constructor
public function RigidBodySpring(body1:IBody, point1:Vector, body2:IBody, point2:Vector, k:Number = 0.01, damp:Number = 0.01)

Creates a new RigidBodySpring

Parameters
body1:IBody — first body involved in spring
 
point1:Vector — point on body1 given in relative coordinates
 
body2:IBody — second body attached to spring
 
point2:Vector — point on body2 given in relative coordinates
 
k:Number (default = 0.01) — spring constant
 
damp:Number (default = 0.01) — damping coefficient
