Unity Script Reference – GUIUtility.ScreenToGUIPoint

GUIUtility.ScreenToGUIPoint

static function ScreenToGUIPoint (screenPoint : Vector2) : Vector2

Description

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.

// the converted GUI positions because of the group.
