GUIUtility.ScreenToGUIPoint

説明

スクリーン座標から、GUI 座標に変換します

::Ref::GUIToScreenPoint から計算した値を再変換させるために使用します。

Note: In Unity the screen space y coordinate varies from zero at the top edge of the window to a maximum at the bottom edge of the window. This is different from what you might expect.

using UnityEngine;

public class Example : MonoBehaviour
{
    // Check the difference between the mouse position (Screen) and
    // the converted GUI positions because of the group.

    void OnGUI()
    {
        Vector2 screenPos = Event.current.mousePosition;
        GUI.BeginGroup(new Rect(10, 10, 100, 100));
        Vector2 convertedGUIPos = GUIUtility.ScreenToGUIPoint(screenPos);
        GUI.EndGroup();
        Debug.Log("Screen: " + screenPos + " GUI: " + convertedGUIPos);
    }
}
