Hello! I know here was theme with this problem but i cant olve it in my project. So I need a help.
I had found a C Script but its doesnt work in my project. Or maybe I not right use it.

//inside class
Vector2 firstPressPos;
Vector2 secondPressPos;
Vector2 currentSwipe;

public void Swipe()
{
     if(Input.touches.Length > 0)
     {
         Touch t = Input.GetTouch(0);
         if(t.phase == TouchPhase.Began)
         {
             //save began touch 2d point
             firstPressPos = new Vector2(t.position.x,t.position.y);
         }
         if(t.phase == TouchPhase.Ended)
         {
             //save ended touch 2d point
             secondPressPos = new Vector2(t.position.x,t.position.y);
                         
             //create vector from the two points
             currentSwipe = new Vector3(secondPressPos.x - firstPressPos.x, secondPressPos.y - firstPressPos.y);
             
             //normalize the 2d vector
             currentSwipe.Normalize();

             //swipe upwards
             if(currentSwipe.y > 0 currentSwipe.x > -0.5f  currentSwipe.x < 0.5f)
             {
                 Debug.Log("up swipe");
             }
             //swipe down
             if(currentSwipe.y < 0 currentSwipe.x > -0.5f  currentSwipe.x < 0.5f)
             {
                 Debug.Log("down swipe");
             }
             //swipe left
             if(currentSwipe.x < 0 currentSwipe.y > -0.5f  currentSwipe.y < 0.5f)
             {
                 Debug.Log("left swipe");
             }
             //swipe right
             if(currentSwipe.x > 0 currentSwipe.y > -0.5f  currentSwipe.y < 0.5f)
             {
                 Debug.Log("right swipe");
             }
         }
