c# - desible GetTouch after 1st touch -

i have object want throw @ distance gettouch.my code working problem when touch screen multiple time,the object move multiple time dont want,i want object move 1 time no matter how many time touch or swipe screen.here's tried.

public class realballmove : monobehaviour {  public float speed; public rigidbody rb;   void start()  {     rb = getcomponent<rigidbody>(); }  void update()  {     if (input.touchcount >0 &&         input.gettouch(0).phase == touchphase.ended || (input.getmousebuttondown(0)))     {         //rb.addforce(vector3.forward * speed);         //rb.addforce(vector3.up * speed);         getcomponent<rigidbody> ().iskinematic = false;          getcomponent<rigidbody> ().addforce (new vector3(0.0f, 20.0f, 12.0f));         //destroy (getcomponent<rigidbody>());     } 

} }

simply add boolean indicating whether have thrown ball ;)

public class realballmove : monobehaviour {      public float speed;     public rigidbody rb;     private bool thrown ;       void start()      {         rb = getcomponent<rigidbody>();     }      void update()      {         if (             !thrown && (             (input.touchcount > 0 && input.gettouch(0).phase == touchphase.ended ) ||             input.getmousebuttondown(0) )         )         {             rb.iskinematic = false;             rb.addforce (new vector3(0.0f, 20.0f, 12.0f));             thrown = true ;         }     } } 

an other option disable script when touch detected, if script lines above , nothing else.
