Question Virtual mouse weird movement issue

Hi!
I found a tutorial (

) about creating a virtual mouse and it should be kinda working, but it's not.

Base code

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.InputSystem;
3. using UnityEngine.InputSystem.LowLevel;
4.  
5. namespace nStation
6. {
7.     public class GamepadCursor : MonoBehaviour
8.     {
9.  
10.         [SerializeField]
11.         private RectTransform cursorTransform;
12.         [SerializeField]
13.         private float cursorSpeed = 1000f;
14.         [SerializeField]
15.         private RectTransform canvasRectTransform;
16.         [SerializeField]
17.         private Camera mainCamera;
18.         [SerializeField]
19.         private Canvas canvas;
20.  
21.         private bool previousMouseState;
22.         private Mouse virtualMouse;
23.  
24.         private void OnEnable()
25.         {
26.             mainCamera = Camera.main;
27.  
28.             if (virtualMouse == null)
29.                 virtualMouse = InputSystem.AddDevice<Mouse>("VirtualMouse");
30.             else if (!virtualMouse.added)
31.                 InputSystem.AddDevice(virtualMouse);
32.  
33.             if(cursorTransform!=null)
34.             {
35.                 Vector2 position = cursorTransform.anchoredPosition;
36.                 InputState.Change(virtualMouse.position, position);
37.             }
38.  
39.             InputSystem.onAfterUpdate += UpdateMotion;
40.         }
41.  
42.         private void OnDisable()
43.         {
44.             InputSystem.RemoveDevice(virtualMouse);
45.             InputSystem.onAfterUpdate -= UpdateMotion;
46.         }
47.  
48.         private void UpdateMotion()
49.         {
50.             if (virtualMouse == null || Gamepad.current == null)
51.                 return;
52.  
53.             Vector2 deltaValue = Gamepad.current.leftStick.ReadValue();
54.             deltaValue *= cursorSpeed * Time.deltaTime;
55.  
56.             Vector2 currentPosition = virtualMouse.position.ReadValue();
57.             Vector2 newPosition = currentPosition + deltaValue;
58.  
59.             newPosition.x = Mathf.Clamp(newPosition.x, 0, Screen.width);
60.             newPosition.y = Mathf.Clamp(newPosition.y, 0, Screen.height);
61.  
62.             InputState.Change(virtualMouse.position, newPosition);
63.             InputState.Change(virtualMouse.delta, deltaValue);
64.  
65.             bool aButtonIsPressed = Gamepad.current.aButton.IsPressed();
66.             if(previousMouseState!= aButtonIsPressed)
67.             {
68.                 virtualMouse.CopyState<MouseState>(out var mouseState);
69.                 mouseState.WithButton(MouseButton.Left, aButtonIsPressed);
70.                 InputState.Change(virtualMouse, mouseState);
71.                 previousMouseState = aButtonIsPressed;
72.             }
73.  
74.             // situation 2
75.             //AnchorCursor(newPosition);
76.  
77.             // situation 1
78.             //cursorTransform.anchoredPosition = newPosition;
79.         }
80.  
81.         private void AnchorCursor(Vector2 position)
82.         {
83.             Vector2 anchoredPosition;
84.             RectTransformUtility.ScreenPointToLocalPointInRectangle(canvasRectTransform, position,
85.                 canvas.renderMode == RenderMode.ScreenSpaceOverlay ? null : mainCamera, out anchoredPosition);
86.             cursorTransform.anchoredPosition = anchoredPosition;
87.         }
88.     }
89. }
90.  

The end of the UpdateMotion() method is where I set the position of the mouse cursor.
If i uncomment the situation 1(

), the mouse cursor moves in the top right quarter of the screen, and the buttons are mouse over, from a side
If I uncomment the situation 2 (

), the mouse cursor mover all the screen, but no mouse over occurs.
What am i doing wrong?

 

I think it's an issue with my scaler, but I really can`t figure it out

 

seems to be a long lasting problem

https://forum.unity.com/threads/virtual-mouse-and-canvas-scaler-scale-with-screen-size.1128836/

I don't know of any nice solution. I hacked around it somehow, but cant remember what I did exactly..

 

if you find your code and could share here, I'd be really glad. I'm still struggling
