public class CircularSlider : MonoBehaviour
{
    public RectTransform handleRect;
    public float minValue = 0f; // Minimum value of the circular slider
    public float maxValue = 1f; // Maximum value of the circular slider

    private float currentValue = 0f; // Current value of the circular slider

    private Vector2 centerPos; // Center position of the circular slider
    private Vector2 startPos; // Starting position of the drag

    private void Start()
    {
        centerPos = handleRect.position;
    }

    private void Update()
    {
        if (Input.GetMouseButtonDown(0)) // Handle drag start
        {
            startPos = Input.mousePosition;
        }
        else if (Input.GetMouseButton(0)) // Handle drag
        {
            Vector2 currentPos = Input.mousePosition;
            Vector2 dir = currentPos - centerPos;
            float angle = Vector2.SignedAngle(Vector2.up, dir.normalized);

            // Convert angle to a normalized value between minValue and maxValue
            float valueRange = maxValue - minValue;
            float normalizedValue = Mathf.InverseLerp(0f, 360f, angle);
            currentValue = minValue + (normalizedValue * valueRange);

            // Update your game logic or UI based on the currentValue
            // For example, you can update a text element to display the currentValue
            // or control the rotation of a game object based on the currentValue
        }
    }
