How do is make Unity 8-way swipe touch control code

 public class InputController : MonoBehaviour{
 
 private Vector2 fp;  // first Touch
 private Vector2 Lp;  // last touch
 
 private int Xdistance;
 private int Ydistance;
 
 private float distance;

 distance=screen.height * 15 / 100;
 }
 
 void Update(){
