I want to do some stuff with game object when I click and drag my mouse horizontally(left and right) or vertically(up and down).I have written some code and it doesnt work fine.could any one please suggest some code for me.thanks in advance..!

this is my java script code..

pragma strict

ar deltaposition:Vector2; var afterdeltaposition:Vector2; var rightSwipe:boolean=false; var upSwipe:boolean=false;

//This is the speed of the Player Object. var MoveSpeed: float = 14; var mindist:float=10; //This is so we can move the position of the Collider Mesh of the Player Object around. var myCollider: BoxCollider; function Start () {

}

function Update () {

   if(Input.GetMouseButtonDown(0))
   {
     deltaposition=Input.mousePosition;
   }
   if(Input.GetMouseButtonUp(0))
   {
       afterdeltaposition=Input.mousePosition;
   }
 
   var ydef =Mathf.Ceil(afterdeltaposition.y-deltaposition.y);
             var xdef=Mathf.Ceil(afterdeltaposition.x-deltaposition.x);
   
   var abs_ydef=Mathf.Abs(ydef);
   var abs_xdef=Mathf.Abs(xdef);
   if(abs_ydef>abs_xdef)
   {
     
     if((ydef>0) && (ydef>200))
     {Debug.Log("swiped up");
     //animation.Play("cubemove");
     Debug.Log(ydef);
     //Debug.Log(xdef);
     ydef=0;
     xdef=0;
     abs_xdef=0;
     abs_ydef=0;
     afterdeltaposition.x=0;
     afterdeltaposition.y=0;
     deltaposition.x=0;
     deltaposition.y=0;
     }
   
     else if((ydef<0) && (ydef<-200) )
     {
     Debug.Log("swiped down");
     //animation.Play("cubemove");
     Debug.Log(ydef);
     ydef=0;
     xdef=0;
     abs_xdef=0;
     abs_ydef=0;
     afterdeltaposition.x=0;
     afterdeltaposition.y=0;
     deltaposition.x=0;
     deltaposition.y=0;
     }
   }
   if(abs_ydef<abs_xdef)
   {
       if((xdef>0) && (xdef>200))
     {Debug.Log("swiped right");
     //animation.Play("cubemove");

     deltaposition.y=0;
     }
     else if((xdef<0) && (xdef<-200))
     {
     Debug.Log("swiped left");
     //animation.Play("cubemove");
     Debug.Log(xdef);
