RuntimePanelUtils.ScreenToPanel

Преобразует абсолютное положение экрана в его эквивалентную локальную координату на данной панели.

Следующий пример преобразует позицию мыши из координат экрана в координаты панели UI Toolkit:

using UnityEngine;
using UnityEngine.UIElements;

public class ScreenToPanelConverter : MonoBehaviour
{
    private UIDocument uiDocument;

    void Awake()
    {
        uiDocument = GetComponent<UIDocument>();
    }

    void Update()
    {
        if (uiDocument == null || uiDocument.rootVisualElement == null)
        {
            return;
        }

        // 1. Get the mouse position in screen pixel coordinates (origin is bottom-left).
        Vector2 screenPosition = Input.mousePosition;

        // 2. Invert the Y-axis to match UI Toolkit's top-left origin.
        screenPosition.y = Screen.height - screenPosition.y;

        // 3. Use the panel's utility function to convert from screen space to panel space.
        // This correctly handles any scaling applied by the panel (for example, Scale with Screen Size).
        IPanel panel = uiDocument.rootVisualElement.panel;
        Vector2 panelPosition = RuntimePanelUtils.ScreenToPanel(panel, screenPosition);

        Debug.Log($"Screen Position: {Input.mousePosition}, Panel Position: {panelPosition}");
    }
}
