Unity获取Scene窗口下的鼠标位置的世界坐标

Unity获取Scene窗口下的鼠标位置的世界坐标

因为直接Camera.main.ScreenToWorldPoint(Event.current.mousePosition);是不行的得进行转换.
直接上代码

    public static Vector3 GetMousePosToScene()
    {
        SceneView sceneView = SceneView.currentDrawingSceneView;
        //当前屏幕坐标,左上角(0,0)右下角(camera.pixelWidth,camera.pixelHeight)
        Vector2 mousePos = Event.current.mousePosition;
        //retina 屏幕需要拉伸值
        float mult = 1;
#if UNITY_5_4_OR_NEWER
        mult = EditorGUIUtility.pixelsPerPoint;
#endif
        //转换成摄像机可接受的屏幕坐标,左下角是(0,0,0);右上角是(camera.pixelWidth,camera.pixelHeight,0)
        mousePos.y = sceneView.camera.pixelHeight - mousePos.y * mult;
        mousePos.x *= mult;
        //近平面往里一些,才能看到摄像机里的位置
        Vector3 fakePoint = mousePos;
        fakePoint.z = 20;
        Vector3 point = sceneView.camera.ScreenToWorldPoint(fakePoint);
        return point;
    }
