Football free kick question?

Is it possible to simulate football free kick? (bend like Beckham). I was able to make straight kicks, no problem by using rigidbody.velocity and rigidbody.addForce.

        if(!target.rigidbody)
           target.AddComponent ("Rigidbody");

           target.rigidbody.velocity.y = kick_velocity;
           target.rigidbody.AddForce (forward * kick_force);

Thanks

You can add a constant force to make the ball curve in the air, you can do this in during FixedUpdate so that it is applied every physics step over several frames.

function FixedUpdate(){
  if(isCurve){
    rigidbody.AddForce(Vector3.right*curveForce);
  }
}
