Football penalty game- Move gameobject in direction of swipe with force

Hello !! I want to make a game in which the user swipes the ball (like kicking the football) and the goalkeeper tries to save it. I also want to swipe the ball in the direction of swipe and also force. In my below code it only checks upward swipe. Can anyone help me how to proceed ?

 var gravity : float = 20.0;
 
 var dis:float=20.0;
 
 var uptest:boolean=true;
 
 var downtest:boolean=true;
 
 var StartPos:Vector2;
 
 var finid:int=-1;
 
 private var moveDirection : Vector3 = Vector3.zero;
 
 function Start()
 {
 
   Physics.gravity = Vector3(0,-25,0);
 
 }
 
 function Update () {
 
     for(var touch:Touch in Input.touches)
         {
             var pos = touch.position;
             if (touch.phase == TouchPhase.Began && finid == -1)
             {
                 finid = touch.fingerId;
                 StartPos = pos;
             }
             else if (touch.fingerId == finid)
             {
                 var delta = pos - StartPos;
                 if (touch.phase == TouchPhase.Moved && delta.magnitude > dis)
                 {
                     finid = -1;
                     if (Mathf.Abs(delta.x) > Mathf.Abs(delta.y))
                     {
                     //
                     }
                     else
                     {
                         if (uptest && delta.y > 0)
                         {
                             
                             //upswipe
                         }
                            
                         else if (downtest && delta.y < 0)
                             {
                                     //downswipe
                             }
                     }
                    
                 }
                 else if (touch.phase == TouchPhase.Canceled || touch.phase == TouchPhase.Ended)
                     finid = -1;
             }
         }
         }
