How can I convert old input system script into a new input system

I want to add fields on my touch screen so I can control my player and camera separately for that I have to use a script called "FixedTouchField.cs" but the problem is that this script was written in a unity old input system and I want to use this script with the unity new input system. So how can I make this script compatible with unity's new input system?

here's the video explaining how to use this script with old input system: https://youtu.be/CmCVtEZUKIs

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.EventSystems;
3. public class FixedTouchField : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
4. {
5. [HideInInspector]
6. public Vector2 TouchDist;
7. [HideInInspector]
8. public Vector2 PointerOld;
9. [HideInInspector]
10. protected int PointerId;
11. [HideInInspector]
12. public bool Pressed;
13. // Use this for initialization
14. void Start()
15. {
16. }
17. // Update is called once per frame
18. void Update()
19. {
20. if (Pressed)
21. {
22. if (PointerId >= 0 && PointerId < Input.touches.Length)
23. {
24. TouchDist = Input.touches[PointerId].position - PointerOld;
25. PointerOld = Input.touches[PointerId].position;
26. }
27. else
28. {
29. TouchDist = new Vector2(Input.mousePosition.x, Input.mousePosition.y) - PointerOld;
30. PointerOld = Input.mousePosition;
31. }
32. }
33. else
34. {
35. TouchDist = new Vector2();
36. }
37. }
38. public void OnPointerDown(PointerEventData eventData)
39. {
40. Pressed = true;
41. PointerId = eventData.pointerId;
42. PointerOld = eventData.position;
43. }
44. public void OnPointerUp(PointerEventData eventData)
45. {
46. Pressed = false;
47. }
48. }

 

Hi
Did you ever fix this?
