public static method ScreenToGUIPoint(screenPoint: Vector2): Vector2;
public static Vector2 ScreenToGUIPoint(Vector2 screenPoint);


Convert a point from screen space to GUI position.

Used for reconverting values calculated from GUIToScreenPoint

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.

See Also: GUIUtility.GUIToScreenPoint.

    // Check the difference between the mouse position (Screen) and
    // the converted GUI positions because of the group.

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